We can figure out how many times a heart beats in one minute (so we can figure out how many minutes it will take for 140 times) by dividing 700 by 10. This gives us 70. Now we know that a heart beats 70 times each minute. Now we know it would take 2 minutes for a heart to beat 140 times because 70×2=140.

Two minutes is the answer.

Lewis directs the school marching band. He uses scale drawings of the football field to design marching formations for the band.
Andrews [41]

Answer:

Assuming you have the lengths in inches.

Do this: (length in inches * 10) x (length in inches * 10)

Step-by-step explanation:

There's information missing from this question. "The football field is 100 yards long and yards wide", but to find out the area of a rectangle you just need to times the two numbers together.

I assume you have a picture with the lengths in inches on, if you can see how many inches are on the scale drawing, times the inches by 10 for the length in yards for each side. Then times the two lengths (in yards) together for the area.

:)
