Tina and nonly wanted to s whose car gets better gas mileage, so they each drove 210 miles and recorded how much gas they used. use the bar graph to find how many miles per gallon each person's car gets. round to the nearest tenth. plz

Tina's car = 17.5 miles and Noly's car = 10.5 miles

Step-by-step explanation:

You know what's so funny, I am doing the winter break homework and I have the same question! Okay, let's do this one together.

Step 1

Do 210 divided by 12 for Tina's car. This equals 17.5 when you round to the nearest tenth.

Step 2

Do 210 divided by 20 for Noly's car. This equals 10.5 when you round to the nearest tenth as well.

So, it's that simple! ( apparently! I was stuck on this problem for 2 days!) Tina's car = 17.5 miles and Noly's car = 10.5 miles. Hope this helped!

sorry, i can't understand your question. will later if you describe more clearly!

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
