Answer:

200.96\ ft

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=\pi D

in this problem

D=64\ ft

substitute

C=\pi (64)=64\pi\ ft -----> exact value of the circumference

Find the approximate value of the circumference

assume

\pi=3.14

64\pi\ ft=64(3.14)=200.96\ ft

A video game is on sale for 20% off. The sale price of the game is $35.00. How much did the game ORIGINALLY cost?
Elena-2011 [213]

Answer:

$43.75

Step-by-step explanation:

To find how much the game would have been 20% off from 43.75, you would have needed the expression

43.75*0.8

So to go from 35 to 43.75, you need the expression

35/0.8.

This expression in simpler terms means What is 38, 80% of?

That is how we get 43.75.

35/0.8 = 43.75.

The value of y varies directly with x, and y= -10 when x=40. Identify the value of y when x=-5
scoray [572]

Answer:

y = 1.25

Step-by-step explanation:

Use the direct variation equation y = kx, and solve for k:

y = kx

-10 = k(40)

-0.25 = k

So, the equation is y = -0.25x. Solve for y when x = -5

y = -0.25x

y = -0.25(-5)

y = 1.25

So, y = 1.25 when x = -5
