Addie walked 2 1/2 miles in 45 minutes. Suzie covered 2 2/5 miles in 2/3 of an hour.
N76 [4]

Answer:

Suzie's speed was 3.6 mph

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ----> the speed in mph (miles per hour)

x ----> the distance in miles

y ----> the time in hours

so

s=\frac{x}{y}

Find Suzie's speed

we have

x=2\frac{2}{5}\ mi

y=\frac{2}{3}\ h

substitute

s=2\frac{2}{5}:\frac{2}{3}

Convert mixed number to an improper fraction

2\frac{2}{5}=2+\frac{2}{5}=\frac{2*5+2}{5}=\frac{12}{5}

substitute

s=\frac{12}{5}:\frac{2}{3}=\frac{36}{10}=3.6\ mph

A local artist creates a piece with two glass cylinders filled with colored water. The second cylinder has the same radius, but
KonstantinChe [14]
The formula for calculating volume of the cylinder is

V= B * H

First volume V1= B * H1  and second volume V2= B * H2

H1= 2 H2 

when we divide V2/V1 = (B*H2)/(B*H1) =>  when we shorten B and B we get

V2/V1 = H2 / H1 when we replace H1 we get V2/V1 = H2/ 2H2

when we shorten H2 and H2 we get V2/V1 = 1/2

The correct answer is the volume of the second cylinder is one-half the volume of the first cylinder.

Good luck!!!
