4. An angle is 50° more than its supplement. Find the angles.
Answers
Answer:
The angles measure \(65\)° and \(115\)°.
Step-by-step explanation:
Supplementary angles are a pair of angles whose measures add up to \(180\)°. In this case, we know that one angle is \(50\)° bigger than the other one, so if we let the measure of one angle be \(x\), then the measure of the other angle will be \(x+50\). Therefore, we can write the following equation to solve for
\(x+x+50=180\)
Solving for \(x\), we get:
\(x+x+50=180\)
\(2x+50=180\) (Simplify LHS)
\(2x+50-50=180-50\) (Subtract \(50\) from both sides of the equation to isolate \(x\))
\(2x=130\) (Simplify)
\(\frac{2x}{2}=\frac{130}{2}\) (Divide both sides of the equation by \(2\) to get rid of \(x\)'s coefficient)
\(x=65\)
Therefore, \(x+50=65+50=115\), so our final answer is that the angles measure \(65\)° and \(115\)°. Hope this helps!

report error the side lengths of $\triangle abc$ are $6$, $8$, and $10$. what is the inradius of $\triangle abc$?
Answers
The inradius of the triangle of the given dimensions will be equal to the value 2.
To find the inradius of a triangle, we need to know the semi perimeter of the triangle, which is half of the perimeter. The perimeter of a triangle is the sum of the lengths of its sides. So, the semi perimeter of triangle ABC is (6+8+10)/2 = 12.
Now that we know the semi perimeter, we can use the formula for the inradius of a triangle:
inradius = √(s-a)(s-b)(s-c)/s
where a, b, and c are the lengths of the sides of the triangle and s is the semi perimeter.
Plugging in the values for a, b, c, and s, we get:
inradius = √(12-6)(12-8)(12-10)/12 = √(6)(4)(2)/12 = √48/12} = √4 = 2
Therefore, the inradius of triangle ABC is 2.

determine whether the series is convergent or divergent. [infinity] k = 1 ke−k2
Answers
Answer:
Convergent
Step-by-step explanation:
One method to determine if \(\displaystyle \sum^\infty_{k=1}ke^{-k^2}\)is convergent or divergent is the Integral Test.
Suppose that the function we use is \(f(x)=xe^{-x^2}\). Over the interval \([1,\infty)\), the function is always positive and continuous, but we also need to make sure it is decreasing before we can proceed with the Integral Test.
The derivative of this function is \(f'(x) = e^{-x^2}(1-2x^2)\), so our critical points will be \(\displaystyle x=\pm\frac{1}{\sqrt{2}}\), but we can drop the negative critical point as we are starting at \(k=1\). Using some test points, we can see that the function increases on the interval \(\bigr[0,\frac{1}{\sqrt{2}}\bigr]\) and decreases on the interval \(\bigr[\frac{1}{\sqrt{2}},\infty\bigr)\). Since the function will eventually decrease, we can go ahead with the Integral Test:
\(\displaystyle \int_{{\,1}}^{{\,\infty }}{{x{{{e}}^{ - {x^2}}}\,dx}} & = \mathop {\lim }\limits_{t \to \infty } \int_{{\,1}}^{{\,t}}{{x{{{e}}^{ - {x^2}}}\,dx}}\hspace{0.5in}u = - {x^2}\\ & = \mathop {\lim }\limits_{t \to \infty } \left. {\left( { - \frac{1}{2}{{{e}}^{ - {x^2}}}} \right)} \right|_1^t\\ & = \mathop {\lim }\limits_{t \to \infty } \left( {-\frac{1}{2}{{e}}^{ - {t^2}}-\biggr(-\frac{1}{2e}\biggr)}} \right) = \frac{1}{2e}\)
Therefore, since the integral is convergent, the series must also be convergent by the Integral Test.

C Depreciation charge £25,000; revaluation surplus £116,000
D Depreciation charge £20,000; revaluation surplus £116,000
Answers
Accoding to the calculations , the correct answer is:
A) Depreciation charge 16,000; revaluation surplus £20,000
According to IAS 16 Property, Plant and Equipment, the depreciation charge for an asset should be based on its carrying amount, useful life, and residual value.
In this case, the buildings were purchased for £400,000 (£480,000 - £80,000) and had a useful life of 25 years. Since there is no residual value, the depreciable amount is equal to the initial cost of the buildings (£400,000).
To calculate the annual depreciation charge, we divide the depreciable amount by the useful life:
£400,000 / 25 = £16,000
Therefore, the depreciation charge for the year ended 30 September 2021 is £16,000.
Now, let's calculate the balance on the revaluation surplus as at that date.
The revaluation surplus is the difference between the fair value of the property and its carrying amount. On 1 October 2020, the property was revalued to £500,000, and the carrying amount was £480,000 (£400,000 for buildings + £80,000 for land).
Revaluation surplus = Fair value - Carrying amount
Revaluation surplus = £500,000 - £480,000
Revaluation surplus = £20,000
Therefore, the balance on the revaluation surplus as at 30 September 2021 is £20,000.
Based on the calculations above, the correct answer is:

given a 14 percent return how long would it take to triple your
investment, solve using time value formula
Answers
It would take approximately 9.4 years to triple your investment with a 14% return, assuming compound interest.
To determine how long it would take to triple your investment with a 14% return, we can use the compound interest formula
Future Value = Present Value × (1 + Interest Rate)ⁿ
In this case, the Future Value is three times the Present Value, the Interest Rate is 14% (or 0.14), and we want to solve for Time.
Let's denote the Present Value as P and the Time as n:
3P = P × (1 + 0.14)ⁿ
Now, we can simplify the equation:
3 = (1.14)ⁿ
To solve for n, we need to take the logarithm of both sides of the equation. Let's use the natural logarithm (ln) for this calculation:
ln(3) = ln((1.14)ⁿ)
Using the logarithmic property, we can bring down the exponent:
ln(3) = n × ln(1.14)
Now, we can solve for t by dividing both sides of the equation by ln(1.14):
n = ln(3) / ln(1.14)
we can find the value of t:
n ≈ 9.4
Therefore, it would take approximately 9.4 years to triple your investment with a 14% return, assuming compound interest.

Answers
To find the average value of f(x)⋅g(x) on 0≤x≤2, we need to first find the integral of f(x)⋅g(x) over the given interval. This can be done by multiplying the functions and integrating the resulting product over the given interval using the definite integral. Once we have the integral, we can divide it by the length of the interval to find the average value.
Assuming we have the functions f(x) and g(x), we can write the integral as:
∫0^2 f(x)⋅g(x) dx
Solving this integral will give us the value of the area under the curve of the product function between the limits of 0 and 2. Once we have this value, we can divide it by the length of the interval (which is 2 in this case) to get the average value of the function.
It's important to note that without knowing the specific functions f(x) and g(x), we cannot give a specific answer to this question. However, we can provide a general method for finding the average value of a product function over a given interval using integration.

Newsvendor: National Geographic still sells a considerable number of copies. Its demand for the August issue is forecasted to be normally distributed with a mean of 80 and a standard deviation of 25. If a store stocks 100 copies, how many copies can they expect to return to the publisher at the end of the month
Answers
Thus, the store can expect to return about 36 copies to the publisher at the end of the month.
The newsvendor problem is a classic inventory optimization problem that seeks to balance the costs of overstocking and understocking.
In this case, we have the demand for the August issue of National Geographic magazine, which is normally distributed with a mean of 80 and a standard deviation of 25.
The store stocks 100 copies of the magazine and wants to know how many copies it can expect to return to the publisher at the end of the month.
To solve this problem, we need to use the normal distribution formula, which is:
Z = (X - μ) / σ
where Z is the standard score, X is the number of copies sold, μ is the mean, and σ is the standard deviation.
We can use this formula to find the probability of selling all 100 copies, which is:
Z = (100 - 80) / 25 = 0.8
P(Z < 0.8) = 0.7881
This means that there is a 78.81% chance of selling all 100 copies.
To find the expected number of returns, we can subtract the expected number of sales from the initial stock:
Expected returns = 100 - (80 x 0.7881) = 36.36
Therefore, the store can expect to return about 36 copies to the publisher at the end of the month.

Answers
a) Simplifying 3^3 x 3^6/ 3^2 x 3^5 using indices rules:We can use the quotient rule of indices which states that when dividing powers of the same base, you subtract the powers. Here, we have a common base of 3.Thus,3^3 x 3^6/ 3^2 x 3^5 = 3^(3+6-2-5) = 3^2Therefore, the main answer is 3^2.b) Conversions:i) To convert 20.22% to a decimal number, we divide by 100:20.22/100 = 0.2022Therefore, 20.22% as a decimal number is 0.2022.ii) To convert 0.16 to a fraction in its simplest form, we first write 0.16 as 16/100.Then, we can simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 16:16/100 = 1/6.25Therefore, 0.16 as a fraction in its simplest form is 1/6.25.c) Finding the HCF and LCM of 24 and 60:The prime factorization of 24 is 2^3 x 3^1.The prime factorization of 60 is 2^2 x 3^1 x 5^1.The HCF is the product of the common factors with the lowest power. Here, the only common factor is 2^2 x 3^1.HCF of 24 and 60 = 2^2 x 3^1 = 12.The LCM is the product of the highest powers of the prime factors. Here, the prime factors are 2, 3 and 5.LCM of 24 and 60 = 2^3 x 3^1 x 5^1 = 120.Therefore, the answer in more than 100 words is:1. In the first part of the question, we used the quotient rule of indices to simplify the expression 3^3 x 3^6/ 3^2 x 3^5. This rule states that when dividing powers of the same base, you subtract the powers. We subtracted the powers of 3 to obtain 3^2 as our final answer.2. In the second part of the question, we performed two different conversions. First, we converted 20.22% to a decimal number by dividing by 100. Then, we converted 0.16 to a fraction in its simplest form by first writing it as a fraction with denominator 100 and then simplifying the fraction by dividing the numerator and denominator by their greatest common factor.3. In the third part of the question, we found the HCF and LCM of 24 and 60. We used the prime factorization method to find the prime factors of both numbers and then used these prime factors to find the HCF and LCM. The HCF is the product of the common factors with the lowest power, while the LCM is the product of the highest powers of the prime factors.
a) Using laws of Indices, we have the solution as: 3²
b) 0.2022.
ii) 4/25
c) HCF = 12
LCM = 12
How to solve Laws of Indices?a) We want to simplify the expression given as:
(3³ × 3⁶)/(3² × 3⁵)
Using the quotient law of indices, we know that when dividing powers of the same base, we subtract the powers. While when multiplying, we add the powers.
The common base is 3 and as such the solution will be:
3³⁺⁶⁻²⁻⁵ = 3²
b) i) We want to convert 20.22% to a decimal number. We can rewrite it as:
20.22/100 = 0.2022.
ii) We want to convert 0.16 to a fraction in its simplest form. This can be rewritten as:
0.16 = 16/100.
Simplifying further gives us 4/25.
c) We want to find the HCF and LCM of 24 and 60.
The prime factors of 24 are: 2 * 2 * 2 * 3.
The prime factorization of 60 gives: 2 * 2 * 3 * 5.
The HCF is the product of the common factors with the lowest power. Thus, HCF of 24 and 60 = 2 * 2 * 3 = 12.
LCM is the product of the highest powers of the prime factors.
Thus, LCM of 24 and 60 = 2 * 2 * 2 * 3 * 5 = 12

Shelby made equal deposits at the beginning of every 3 months into an RRSP. At the end of 9 years, the fund had an accumulated value of $55,000. If the RRSP was earning 3.50\% compounded monthly, what was the size of the quarterly deposits? Round to the nearest cent
Answers
The size of the quarterly deposits in Shelby's RRSP account was approximately $147.40.
Let's denote the size of the quarterly deposits as \(D\). The total number of deposits made over 9 years is \(9 \times 4 = 36\) since there are 4 quarters in a year. The interest rate per period is \(r = \frac{3.50}{100 \times 12} = 0.0029167\) (3.50% annual rate compounded monthly).
Using the formula for the future value of an ordinary annuity, we can calculate the accumulated value of the RRSP fund:
\[55,000 = D \times \left(\frac{{(1 + r)^{36} - 1}}{r}\right)\]
Simplifying the equation and solving for \(D\), we find:
\[D = \frac{55,000 \times r}{(1 + r)^{36} - 1}\]
Substituting the values into the formula, we get:
\[D = \frac{55,000 \times 0.0029167}{(1 + 0.0029167)^{36} - 1} \approx 147.40\]
Therefore, the size of the quarterly deposits, rounded to the nearest cent, is approximately $147.40.

We can say that the y intercept is at the location (0,-1)
This is where the graph crosses the vertical y axis. This is 1 unit below the origin.
This is assuming each tickmark on the grid represents 1 unit.
Answer:
The y- intercept is (0,-1)
Step-by-step explanation:
A y- intercept is when a point intercepts (crosses) the y- axis. Since the dot does not cross the x- axis, that point will be 0. It is below the y- axis, meaning it will be -1.
A company currently has 200 units of a product on-hand that it orders every two weeks (14 days) when the salesperson visits the premises. Demand for the product averages 20 units per day with a standard deviation of 5 units. Lead time for the product to arrive is seven days. Management has a goal of a 95 percent probability of not stocking out for this product. The salesperson is due to come in late this afternoon when 180 units are left in stock (assuming that 20 are sold today). How many units should be ordered?
Answers
To determine the number of units that should be ordered, we need to consider the lead time, demand, and the desired probability of not stocking out.
1. First, let's calculate the demand during the lead time. Since the lead time is 7 days and the average daily demand is 20 units, the demand during the lead time is 7 days * 20 units/day = 140 units.
2. Next, we calculate the safety stock needed to achieve the 95% probability of not stocking out. The safety stock is the product of the standard deviation and the Z-score corresponding to the desired service level. For a 95% probability, the Z-score is 1.65. So, the safety stock is 1.65 * 5 units = 8.25 units (rounding up to 9 units).
3. Now, we calculate the reorder point, which is the sum of the demand during the lead time and the safety stock. Reorder point = 140 units + 9 units = 149 units.
4. Finally, we subtract the current on-hand units and the units sold today from the reorder point to determine the number of units to be ordered. Units to be ordered = 149 units - 180 units + 20 units = -11 units.
Since we cannot order a negative number of units, we conclude that no units should be ordered in this scenario.
Based on the given information and calculations, no units should be ordered in this case as there is no need to replenish the stock.

jackie has a checking account. For each day that her checking account balance falls below zero, she is charged by the bank a fee of $7.50 per day. Her current balance in the account is –$12.50. If she does not make any deposits or withdrawals, what will be the new balance in her account after 2 days? Show your work.
Answers
The new balance in Jackie's account after 2 days will be -$27.50.
How to illustrate the expression?It should be noted that for each day that her checking account balance falls below zero, she is charged by the bank a fee of $7.50 per day.
Since her current balance in the account is –$12.50, the new balance after 2 days will be:
= -12.50 + (-7.50 × 2)
= -12.50 + -15
= -27.50
The balance is -27.50

There are a total of 8 tiles in the bag containing the
following letters: G, I, R, V, I, A, I and N.
a) What is the probability of selecting an I, keeping it, then an A?
The probability of selecting an I is
b) Does the probability of selecting an A increase or decrease after the first “I” tile is pulled from the bag?
c) What is the probability of drawing all three “I” tiles from the bag, one at a time?
d) Will drawing an “A,” keeping it, then drawing an “I” be more or less likely than drawing an “I,” keeping it, then drawing another “I”?
Answers
Answer:
a) P(IA) = 3/56; P(I) = 3/8
b) increases
c) 1/56
d) less
Step-by-step explanation:
You want various probabilities related to drawing letters from a bag containing the letters G, I, R, V, I, A, I, and N.
The probability of drawing a given letter is the ratio of the number of that letter in the bag to the total number of letters in the bag.
a) P(IA) without replacementThere are 3 letters I in the bag. There is only one of each of the other 5 letters.
P(I) = 3/8
P(A after I) = 1/7
The probability of a sequence of I then A is the product of these probabilities:
P(IA) = (3/8)(1/7) = 3/56
b) Change in P(A)
Before the first I is pulled from the bag, P(A) = 1/8.
After the first I is pulled from the bag, P(A) = 1/7, an increase in the probability.
(You can see that the probability of selecting an A increases after each non-A letter is drawn. Ultimately, after the other 7 letters are drawn, P(A) = 1, as it is the only one left.)
c) P(III)P(I) = 3/8 on the first draw
P(I) = 2/7 after the first I is drawn
P(I) = 1/6 after the second I is drawn
P(III) = (3/8)(2/7)(1/6) = 1/56
d) P(AI) vs P(II)
P(AI) = (1/8)(3/7) = 3/56
P(II) = (3/8)(2/7) = 6/56 = 3/28
Drawing A then I is less likely than drawing I then I.

The sum of a geometric series is 55.5625. The first term of the series is 28, and its common ratio is 0.5. How many terms are there in the series?
(Type a whole number.)
Answers
The number of terms in geometric series with common ratio 0.5 is 5.
What is a geometric series?A geometric series is a set of integers where each term following the first is created by multiplying the term before it by a predetermined value called the common ratio. To put it another way, each term in the series is created by multiplying the term before it by a set integer.
The sum of a finite geometric sequence is given by the formula:
\(S = a(1 - r^n)/(1 - r)\)
Where, S is the sum of the series,
a is the first term,
r is the common ratio, and n is the number of terms.\(55.5625 = 28(1 - 0.5^n)/(1 - 0.5)\\\\55.5625(1 - 0.5) = 28(1 - 0.5^n)\\27.5625 = 28 - 28(0.5)^n\\0.4375 = (0.5)^n\\n = log(0.4375)/log(0.5)\\n = 4.17\)
Rounding the numbers, we have n = 5.
Hence, the number of terms in geometric series is 5.
