Solve for x and then determine the measure of the exterior angle.

neonofarm [45]

Answer:

x=25, 120

Step-by-step explanation:

The two angles form a straight line so they add to 180

60 + 4x +20 =180

Combine like terms

4x+80 = 180

Subtract 80 from each side

4x+80-80 =180-80

4x= 100

Divide by 4

4x/4 =100/4

x= 25

The exterior angle is

4x+20 = 4*25+20 =100+20 =120

Volume of a cylinder= (height) x area of the base (circle)

We know the height = 160 cm (given), let's find the radius of the base.

The circumference of the base = 87.92 = 2πR==> R=87.92/(2π) =13.993 cm

Area of circle = πR²=π(13.993)² = 615.128 cm²

Hence the volume of the cylinder = 615.128 x 160 = 92,420.48 cm³

What is the ratio AC: CB?

sleet_krkn [62]

Answer:

D. 1 : 2

Step-by-step explanation:

Given:

A(-6, -2),

B(6, 7),

C(-2, 1)

Required:

Ratio of AC : CB

SOLUTION:

Find AC:

$AC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$A(-6, -2) = (x_1, y_1)$

$C(-2, 1) = (x_2, y_2)$

$AC = \sqrt{(-2 -(-6))^2 + (1 -(-2))^2}$

$AC = \sqrt{(4)^2 + (3)^2}$

$AC = \sqrt{16 + 9} = \sqrt{25}$

$AC = 5$

Find CB:

$CB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$C(-2, 1) = (x_1, y_1)$

$B(6, 7) = (x_2, y_2)$

$CB = \sqrt{(6 -(-2))^2 + (7 - 1)^2}$

$CB = \sqrt{(8)^2 + (6)^2}$

$CB = \sqrt{64 + 36} = \sqrt{100}$

$CB = 10$

Find AC : CB

AC : CB = 5 : 10 = 1 : 2

For the first 2 home football games, the concession stand sold a total of 70 hamburgers. How many hamburgers can they expect to

sasho [114]

Answer:

385 hamburgers.

Step-by-step explanation:

So the data they have given us is that there have been 2 home games, with 70 hamburgers sold. If we divide the number of hamburgers sold by the number of games (70/2), we come up with the average hamburgers sold per game, which is 35. We can use an equation to find the amount of hamburgers sold for every x amount of games. $h = 35x$ , with x being the amount of games, and h being the total amount of hamburgers. If you plug in 11 for x, you will get 385.
