\(\qquad\displaystyle \tt \dashrightarrow \: x = 20\)
Value of x = 20°
Hey! there . Thanks for your question :)
Answer:
20° is the correct answer.Step-by-step explanation:
In this question we are given with two interior angles of the triangle that are 40° and 70° , also we are given an exterior angle that is (5x + 10)°. And we are asked to find the value of angle x.
Solution :-
For finding the value of angle x , we have to use exterior angle property of triangle which states that sum of opposite interior angles of triangle is equal to the given exterior angle. So :
Step 1: Making equation :
\( \longmapsto \: \sf{40 {}^{°} + 70 {}^{°} = (5x + 10) {}^{°} }\)
Solving :
\( \longmapsto \: \sf{110 {}{°} = (5x) {}^{°} +10 {}^{°} }\)
Step 2: Subtracting 10 on both sides :
\( \longmapsto \sf{ 110 {}^{°} - 10 {}^{°} = 5x + \cancel{10 {}^{°}} - \cancel{10 {}^{°} } }\)
We get ,
\( \longmapsto \sf{(5x ){}^{°} = 100 {}^{°} }\)
Step 3: Dividing both sides by 5 :
\( \longmapsto \dfrac{ \cancel{5}x {}^{°} }{ \cancel{5}} = \dfrac{ \: \: \: \: \cancel{ 100} {°}^{} }{ \cancel{5} }\)
On cancelling , we get :
\( \longmapsto \underline{\boxed{\red{\sf{ \bold{ x = 20 {}^{°} }}}}} \: \: \bigstar\)
Therefore , value of x is '20°'Verification :-
For verifying sum of both the interior angles is equal to given exterior angles. As we get the value of x as 20 we need to substitute it's value in place x and then L.H.S must be equal to R.H.S :
40° + 70° = 5(20°) + 10°110° = 100° + 10°110° = 110°L.H.S = R.H.STherefore , our answer is correct .

The marginal cost when x = 25 and when x = 100 are $0.1 and $0.05 respectively.
What is a Marginal Production Cost?A marginal production cost is a derivative of a cost function. From the information given, the total cost is:
C(x) = \(\mathbf{\sqrt{x}}\)The marginal production cost can be expressed as:
\(\mathbf{C'(x) = \dfrac{d}{dx}(\sqrt{x})}\)
\(\mathbf{C'(x) = \dfrac{1}{2\sqrt{x}}}\)
However, when the cost is 25, the marginal production is:
\(\mathbf{C'(25) = \dfrac{1}{2\sqrt{25} }}\)
\(\mathbf{C'(25) = \dfrac{1}{2\times5}}\)
\(\mathbf{C'(25) = \dfrac{1}{10}}\)
C' (25) = $0.1
Also, when the cost is 100, the marginal production is:
\(\mathbf{C'(100) = \dfrac{1}{2\sqrt{100} }}\)
\(\mathbf{C'(100) = \dfrac{1}{2\times10}}\)
\(\mathbf{C'(100) = \dfrac{1}{20}}\)
C' (100) = $0.05

what’s the quotient of -15b^5+18b^3/3b
This is the quotient of (-15b^5 + 18b^3) divided by 3b. The expression simplifies to -5b^4 + 6b^2.
To find the quotient of the expression (-15b^5 + 18b^3) divided by 3b, we can perform the division by simplifying each term separately.
First, let's divide -15b^5 by 3b:
(-15b^5) / (3b) = -15/3 * b^5/b = -5 * b^(5-1) = -5b^4
Next, let's divide 18b^3 by 3b:
(18b^3) / (3b) = 18/3 * b^3/b = 6 * b^(3-1) = 6b^2
Now, we have simplified each term individually. The resulting expression is:
-5b^4 + 6b^2
This is the quotient of (-15b^5 + 18b^3) divided by 3b. The expression simplifies to -5b^4 + 6b^2.

_____________________
25/x = 5.5/9.9
25 × 9.9 = x × 5.5
247.5 = x × 5.5
x × 5.5 = 247.5
x = 247.5 : 5.5
x = 45 wooden
Good luck! :)
Answer:
45
Step-by-step explanation:
In questions such as these it is implied Anita can and does work at a constant rate. Therefore, we can set up the following proportion:
\(\frac{25}{5.5}=\frac{x}{9.9}\), where \(x\) represents the number of wooden slats she can paint in 9.9 hours.
Multiplying both sides by 9, we get:
\(x=\frac{9.9\cdot 25}{5.5},\\x=\boxed{45}\)

Answer:
(2,5)
Step-by-step explanation:
\(\left(\frac{9-5}{2}, \frac{0+10}{2} \right)=(2,5)\)
The Midpoint of the Line Segment AB that has the endpoints A(9,0) and B(-5,10) is (2,5).
What is the lie segment?In geometry, a line segment is a part of a line that is bounded by two end points, and contains every point on the line that is between end points.
Now it is given that,
The endpoints of line segment is A(9,0) and B(-5,10)
So, x₁ = 9
y₁ = 0
x₂ = -5
y₂ = 10
To find the midpoint of AB we have,
{[(x₁+x₂ )/2] , [(y₁+y₂ )/2]}
Put the values, we get
{[(9+(-5) )/2] , [(0+10 )/2]}
solving them,
{(4/2) ,(10/2)}
or,
(2,5)
which is the required midpoint of the line segment.

Which set of numbers can represent the side lengths, in centimeters, of a right triangle?
A set of numbers that can represent the side lengths, in centimeters, of a right triangle is any set that satisfies the Pythagorean theorem, where the square of the hypotenuse's length is equal to the sum of the squares of the other two sides.
A right triangle is a type of triangle that contains a 90-degree angle. According to the Pythagorean theorem, in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Let's consider a set of numbers that could represent the side lengths of a right triangle in centimeters.
One possible set could be 3 cm, 4 cm, and 5 cm.
To verify if this set forms a right triangle, we can apply the Pythagorean theorem.
Squaring the length of the shortest side, 3 cm, gives us 9. Squaring the length of the other side, 4 cm, gives us 16.
Adding these two values together gives us 25.
Finally, squaring the length of the hypotenuse, 5 cm, also gives us 25. Since both values are equal, this set of side lengths satisfies the Pythagorean theorem, and hence forms a right triangle.
It's worth mentioning that the set of side lengths forming a right triangle is not limited to just 3 cm, 4 cm, and 5 cm.
There are infinitely many such sets that can be generated by using different combinations of positive integers that satisfy the Pythagorean theorem.
These sets are known as Pythagorean triples.
Some other examples include 5 cm, 12 cm, and 13 cm, or 8 cm, 15 cm, and 17 cm.
In summary, a right triangle can have various sets of side lengths in centimeters, as long as they satisfy the Pythagorean theorem, where the square of the hypotenuse's length is equal to the sum of the squares of the other two sides.

The population of a city in Texas is about 1,030,000. The population of the city in t years can be predicted using the equation P = 1,030,000(1.12)t. According to this equation, what will the approximate population of the city be in 9 years? 10,382,400
Answer:
2,856,271
Step-by-step explanation:
We presume your equation is intended to be ...
P = 1,030,000(1.12)^t
To find the prediction in 9 years, put 9 where t is and do the arithmetic.
P = 1030000(1.12^9) ≈ 2,856,271
In 9 years, the population is predicted to be about 2,856,271.
Answer:
To predict the population in nine years, substitute 9 for t in the equation and simplify:
P = 1,030,000(1.12)9

a) The mean of the data-set is of 2.
b) The range of the data-set is of 4 units, which is of around 4.3 MADs.
How to obtain the mean of a data-set?The mean of a data-set is obtained as the sum of all observations in the data-set divided by the number of observations in the data-set, which is also called the cardinality of the data-set.
The dot plot shows how often each observation appears in the data-set, hence the mean of the data-set is obtained as follows:
Mean = (1 x 0 + 5 x 1 + 3 x 2 + 5 x 3 + 1 x 4)/(1 + 5 + 3 + 5 + 1)
Mean = 2.
The range is the difference between the largest observation and the smallest, hence:
4 - 0 = 4.

The simplified expression is d/ c⁴.
To simplify the expression cd³ c⁻⁵ x d⁻², we can combine the variables with the same base (c and d) by adding their exponents:
Using the property of exponents as
Product Rule:When multiplying two exponential expressions with the same base, you can add the exponents. This can be expressed as follows:
aᵇ x aⁿ= aᵇ⁺ⁿ
Quotient Rule:When dividing two exponential expressions with the same base, you can subtract the exponents. This can be expressed as follows:
aᵇ / aⁿ= aᵇ⁻ⁿ
So, cd³ c⁻⁵ x d⁻²
= c¹⁻⁵ x d³⁻²
= c⁻⁴ x d¹
= dc⁻⁴
Again from the property of exponents
a⁻ᵇ = 1/aᵇ
So, dc⁻⁴

Answer: 2x+5=75. X=35.
Step-by-step explanation: Let’s make the number x. It says twice the number. So that would be x times 2 or two x. Then the sum of twice a number and five. So it would be 2x+5. That equals to 75. So the equation would be 2x+5=75. Then to solve it, subtract five from both sides. 2x=70. Then divide the whole thing by two. X=35.

Answer:
(a): \(\bar x = 5.54\) and \(Median = 4.86\)
(b): \(\bar x = 5.27\) and \(Median = 5.21\)
(c): New York Yankees
Step-by-step explanation:
Given
Data of New York ERA and Baltimore ERA
Solving (a): Mean and Median of New York ERA
Mean is calculated as:
\(\bar x = \frac{\sum x}{n}\)
For New York ERA, n = 19. So, we have:
\(\bar x = \frac{3.13 + 2.88 + 4.99 + 3.99 + 4.68 + 5.80 + 6.81 + 0.98 + 4.86 + 5.93 + 2.88 + 3.92 + 4.08 + 3.00 + 7.50 + 9.00 + 5.40 + 7.36 + 18.00}{19}\)
\(\bar x = \frac{105.19}{19}\)
\(\bar x = 5.53631578947\)
\(\bar x = 5.54\)
To calculate the median value, we first arrange the data (in ascending order):
So, we have:
0.98, 2.88, 2.88, 3.00, 3.13, 3.92, 3.99, 4.08, 4.68, 4.86, 4.99, 5.40, 5.80, 5.93, 6.81, 7.50, 7.36, 9.00, 18.00
The median value of odd number of data is:
\(Median = \frac{1}{2}(n+1)\ th\)
Substitute 19 for n
\(Median = \frac{1}{2}(19+1)\ th\)
\(Median = \frac{1}{2}(20)\ th\)
\(Median = 10th\)
So, the median is the 10th item.
\(Median = 4.86\)
(b): Mean and Median of Baltimore ERA
Mean is calculated as:
\(\bar x = \frac{\sum x}{n}\)
For Baltimore ERA, n = 17. So, we have:
\(\bar x = \frac{4.58+ 5.77+ 5.21+ 6.51+ 4.29+ 2.50+ 5.23+ 4.31+ 4.87+ 3.14+ 2.57+ 7.92+ 7.79+ 5.40+ 2.92+ 10.13+ 6.52}{17}\)
\(\bar x = \frac{89.66}{17}\)
\(\bar x = 5.27411764706\)
\(\bar x = 5.27\) --- approximated
Arrange in ascending order:
2.50 , 2.57 , 2.92 , 3.14 , 4.29 , 4.31 , 4.58 , 4.87 , 5.21, 5.23 , 5.40 ,5.77 , 6.51 , 6.52, 7.79 , 7.92 , 10.13
\(Median = \frac{1}{2}(n+1)\ th\)
\(Median = \frac{1}{2}(17+1)th\)
\(Median = \frac{1}{2}(18)th\)
\(Median = 9th\)
So, the median is the 9th item.
\(Median = 5.21\)
(c): Who has a better record
Statistically, the average ERA of New York Yankees is better than the average ERA of Baltimore Orioles.
Hence, New York Yankees hold the better record

raul wants to know if reading a book or watching a movie has a lower cost per minute the book Costs $15 and takes Raul 200 minutes to read the movie costs 14 and takes Raul 2 hours and 39 minutes to watch does the book or the movie have a lower cost per minute
The book has a lower cost per minute than the movie.
To find the cost per minute of the book, we divide the cost by the number of minutes:
cost per minute of book = $15 / 200 minutes = $0.075 per minute
To find the cost per minute of the movie, we need to convert the time to minutes.
2 hours and 39 minutes is equal to:
2 hours x 60 minutes/hour = 120 minutes
39 minutes = 39 minutes
Total minutes = 120 + 39 = 159 minutes
cost per minute of movie = $14 / 159 minutes = $0.088 per minute
Therefore, the book has a lower cost per minute than the movie.
