The two triangles in the shown figure are similar, therefore conclusion can be made that :

Ratio of its it's corresponding sides is equal.

\(\qquad \sf  \dashrightarrow \: \dfrac{2x - 4 + 6}{6} = \dfrac{24}{4} \)

\(\qquad \sf  \dashrightarrow \: \dfrac{2x + 2}{6} = 6\)

\(\qquad \sf  \dashrightarrow \: 2x + 2 = 6 \times 6\)

\(\qquad \sf  \dashrightarrow \: 2x + 2 = 36\)

\(\qquad \sf  \dashrightarrow \: 2x = 36 - 2\)

\(\qquad \sf  \dashrightarrow \: 2x = 34\)

\(\qquad \sf  \dashrightarrow \: x = 17\)

Therefore, The value of x is " 17 "

Now, the measure of side BC is :

\(\qquad \sf  \dashrightarrow \: 2x - 4\)

\(\qquad \sf  \dashrightarrow \:2 (17) - 4\)

\(\qquad \sf  \dashrightarrow \: 34 - 4\)

\(\qquad \sf  \dashrightarrow \: 30 \: \: units\)

So, its perimeter will be :

\(\qquad \sf  \dashrightarrow \: p = AB + AB + BC \)

\(\qquad \sf  \dashrightarrow \: p = 24 + 26 + 30\)

\(\qquad \sf  \dashrightarrow \: p = 80 \: \: units\)

The estimated required sample size is approximately 62 students. To determine the estimated required sample size, we can use the formula for sample size calculation in estimating a population mean with a specified margin of error:

n = (Z * σ / E)^2

Where:

n = required sample size

Z = Z-score corresponding to the desired confidence level (95% confidence level corresponds to a Z-score of approximately 1.96)

σ = estimated standard deviation of the population

E = desired margin of error

In this case, the desired margin of error is $25, and the estimated standard deviation is $125.

Substituting these values into the formula, we have:

n = (1.96 * 125 / 25)^2

n = (196 / 25)^2

n = 7.84^2

n ≈ 61.44

Rounding up to the nearest whole number, we get the estimated required sample size of 62.

Therefore, in order to estimate the average amount that students spend per week on groceries within a margin of error of $25, with a 95% confidence level and an estimated standard deviation of $125, a sample size of approximately 62 students would be needed. This sample size should provide a reasonable estimate of the population mean with the desired level of precision.

The product of a rational and an irrational number can be either rational or irrational, depending on the specific numbers involved.

To illustrate this, let's consider an example:

Let's say we have the rational number 2/3 and the irrational number √2.

Their product would be (2/3) * √2.

In this case, the product is irrational.

The square root of 2 is an irrational number, and when multiplied by a rational number, the result remains irrational.

However, it's also possible to have a product of a rational and an irrational number that is rational. For example, if we consider the rational number 1/2 and the irrational number √4, their product would be (1/2) * 2, which equals 1. In this case, the product is a rational number.

Therefore, we cannot make a definitive statement that the product of a rational and an irrational number is always rational or always irrational. It depends on the specific numbers involved in the multiplication.

Answer:

9°

Explanation:

So, since the arrow is pointing to a RIGHT angle, you have to know the right angle's degree is 90° so set up an equation.

11x - 9 = 90

Now you solve it. Here's a step by step:

11x - 9 = 90

Add nine to nine and ninety. Since the nine in this equation is negative, it'll cancel it out. Now here's what you have left to solve:

11x = 99

Divide -11 from 11 and 99.

x = 9

If you feel like you're wrong, fill it in!

11(9) - 9 = 90

11 x 9 = 99

99 - 9 = 90

There you go!

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Step-by-step explanation:

since it is a right and isosceles triangle, therefore :

X = Y = (180-90)/2 = 90/2 = 45

X = 45°

Y = 45°

The shorter piece is 3.17 inches long and the longer piece is 5 times as long, or 15.83 inches long. Together, they add up to the original length of 19 inches.

Let's start by using algebra to solve the problem. Let x be the length of the shorter piece, then the length of the longer piece is 5x. We know that the total length of the pipe is 19 inches, so we can write an equation:

x + 5x = 19
Simplifying, we get:
6x = 19
Dividing both sides by 6, we get:
x = 19/6
So the length of the shorter piece is:
x = 3.17 inches (rounded to two decimal places)

The monthly payment you would need to deposit in the account over 25 years to get $300,000 would be $574.88, and the total interest you will earn will be $156,535.49.

a) The present value of the future amount (which is 25 years from now) = $300,000

Amount of interest per year = 6%

To find out how much you need to deposit in the account each month, you can use the formula for Future Value of Annuity or Annuity Due:

\(\[FVA = PMT \times \frac{{((1 + r)^n) - 1}}{r}\]\)

Where:

FVA = Future Value of Annuity

PMT = Payment

r = Rate per period

n = Number of periods of investment

We can rearrange the formula to solve for PMT:

\(\[PMT = \frac{{FVA}}{{((1 + r)^n) - 1}} \div r\]\)

Putting in the values, we get:

\(\[FVA = $300,000\]\)

\(\[r = \frac{{6\%}}{{12}}\)\)) (since the rate is per year and we need monthly payments)

\(\[n = 25 \times 12\)\) (since we need to calculate for monthly payments over 25 years)

Therefore:

\(\[PMT = $-574.88\]\)

The monthly amount to be deposited in the account will be $574.88. We can round off to the nearest dollar.

b) The total amount of interest you will earn will be the future value of all the deposits minus the principal amount. We already know the future value from the previous calculation, which is $300,000.

To find out the total amount of principal to be deposited, we can use the following formula:

\(\[P = PMT \times \frac{{(1 - (1 + r)^{-n})}}{r}\]\)

Where:

P = Principal

PMT = Payment

r = Rate per period

n = Number of periods of investment

Putting in the values, we get:

\(\[P = $-143,464.51\]\)

Therefore, the total interest you will earn will be the future value minus the total principal deposited:

$300,000 - $143,464.51 = $156,535.49

Therefore, you will earn a total of $156,535.49 in interest over the 25-year period. Hence, this is the main answer.

Therefore, the monthly payment you would need to deposit in the account over 25 years to get $300,000 would be $574.88, and the total interest you will earn will be $156,535.49.

The after-tax present worth according to the given values is $732,140.56 and the internal rate of return is 22.65%.

(a) To compute the after-tax present worth, we need to determine the net cash flow for each year and discount it to present value using the after-tax MARR of 15%.

Year 0: Initial cost of equipment = -$18,600
Years 1-10:
Revenue from bags = (100.3 bags/carton) x ($0.03/bag) x (200,000 cartons/year) = $120,780
Cost savings from reducing overfilling = (5.5%) x ($0.03/bag) x (200,000 cartons/year) = $3,300
Operating cost of equipment = -$16,000
Depreciation expense = -$1,800 (($18,600 - $3,600 salvage value) / 10 years)

Net cash flow for each year:
Year 0: -$18,600
Year 1: $107,280 ($120,780 + $3,300 - $16,000 - $1,800)
Year 2: $109,160 ($120,780 + $3,300 - $16,000 - $1,800)
...
Year 10: $113,640 ($120,780 + $3,300 - $16,000 - $1,800)

Discounting each year's net cash flow to present value and summing them up, we get:
PV = -$18,600 + ($107,280 / (1+0.15)^1) + ($109,160 / (1+0.15)^2) + ... + ($113,640 / (1+0.15)^10)
PV = -$18,600 + $750,740.56
PV = $732,140.56

Therefore, the after-tax present worth is $732,140.56.

(b) To compute the after-tax internal rate of return, we need to find the discount rate that makes the net present value equal to zero. We can use trial and error or a financial calculator to solve this.

Using trial and error, we find that a discount rate of approximately 22.65% makes the net present value equal to zero. Therefore, the after-tax internal rate of return is approximately 22.65%.

(c) To compute the after-tax simple payback period, we need to determine how long it takes for the cumulative net cash flow to equal the initial cost of the equipment.

Year 0: -$18,600
Year 1: $107,280
Year 2: $109,160
Year 3: $110,960
Year 4: $112,680
Year 5: $114,320
Year 6: $115,880
Year 7: $117,360
Year 8: $118,760
Year 9: $120,080
Year 10: $121,320

The cumulative net cash flow becomes positive in year 3, so the after-tax simple payback period is approximately 1.9 years (between year 2 and year 3).

Now we can check if b is not in the set spanned by the columns of A. To do this, we can calculate the dot product of b and each column of A. If the dot product of any of the columns is equal to b, then b is in the set spanned by the columns of A. Since none of the dot products are equal to b, we can conclude that b is not in the set spanned by the columns of A.
