Answer:

The volume of the cube is 1/2 x 1/2 x 1/2 = 1/8

length x width x height = volume

1x2x2.5=5

2 1/2 = 2.5 because 1/2=0.5

to divide fractions multiply the reciprocal. The reciprocal is the fraction flipped over

5 / 1/8 = 5 x 8/1

5x8/1=40

40 cubes

Answer:

16.4 m to the nearest tenth.

Step-by-step explanation:

After the next bounce it rises to 50*(0.8)^2 = 32 m

So after the 5th bounce it rises to 50(0.8)^5 = 16.4 m. (answer).

Given the function below, find x if f(x)=11<br> f(x) = 3x + 5

sattari [20]

X = 2
plug in 11 into f(x) and you get 11 = 3x + 5
subtract 5 from both sides and you get 6 = 3x
divide 3 from both sides and you get x = 2
if you plug in 2 for x, you should get 11.
