Terri can swim 3 laps in 2.5 minutes. To find how long it takes to swim 20 laps, you can make a proportion.
Put the amount of laps on the top and the time(minutes) at the bottom.
Cross multiply:
Divide by 3:
It would take Terri 
OR 
minutes to run 20 laps.
Add all the numbers up and divide by 5 to get your answer. I believe in you.
Answer:
f(5) = 25
Step-by-step explanation:
f(x) = 3x + 10
f(5) = 3(5) + 10
f(5) = 15 + 10
f(5) = 25
1/2 < 3/4
1/2 is = 2/4
and 2/4 < 3/4
therefore 1/2 must be < 3/4
Height = 3 cubes
Width = 5 cubes
Depth = 4 cubes
Number of Cubes = 3*4*5 = 60
Each cube is .2 inches on each side
So, it's volume = 1 * .6 * .8 = .48 cubic inches
Double - Check
Each cube is .2*.2*.2 =

cubic inches
There are 60 cubes so the volume =
60 * .008 = .48 cubic inches CORRECT !!
