Answer:

1) Mistake is that vertical angles are congruent and equal meaning the product of 5x should be equal to the other side being 100. Answer is x=20

2) Mistake is that the angle's measure should've added up to 90. Answer is x=17

3) The math is done incorrectly with the first step as the coefficients can't be added with constants. Answer is x=21.5

Answer:

1. Since the angles on the both sides are the same

5x = 100

x = 20

The mistake is that it is absolutely unnecessary to use 180.

2. It is a right angle, which means it would be 90 degrees instead of 180.

3x + 39 = 90

3x + 39 - 39 = 90 - 39

3x = 51

3x = 17

3. The process is wrong

It should be

6x + 2x + 8 = 180

8x + 8 = 180

8x = 172

x = 21.5

Answer: V=9651 ft^3

Explanation: This is a volume question and the formula for volume of a cylinder is πr^2h.

The radius is the diameter divided by 2, which is 8.

We can put the equation in terms of π by doing π*(8^2*48)=3072π.

Solving this gives us about 9650.972632, which you can round to get 9651.

Using the model equation, the predicted mean score on the final given a score of <em>10 points above the class mean</em> in the mid term exam is 50.7

<u>The Least - Square Regression equation which models the relationship between midterm and final exam score is</u> :

γ=46.6 + 0.41x

x = 10 points ; <u>substitute the value of x = 10 into the regression equation</u> ;

γ=46.6 + 0.41(10)

γ=46.6 + 4.1

γ = 50.7

The <em>number of points above the mean</em> he'll score in the final exam is predicted to be 50.7

Help me please find the value of x then find the measure of each unknown angle

neonofarm [45]

The value of x is 103.

The value of x is 59.

The value of x is 134.

The value of x is 12

The value of x is 50

The value of x is 135

<h3>What is the value of x?</h3>

The sum of angles on a straight line add up to 180 degrees.

180 - 77 = 103

180 - 121 = 59

180 - 46 = 134

12 x + 36 = 180

12x = 180 - 36

12x = 144

x = 12

24 + 3x + 6 = 180

3x = 180 - 24 - 6

3x = 150

x - 50

$\frac{x}{3}$ + 99 + 36 = 180

$\frac{x}{3}$ = 180 - 36 - 99

$\frac{x}{3}$ = 45

x = 45 x 3

x = 135
