a paper airplane can be made out of two different pieces of paper: a circular piece 10 inches wide and a square piece 11 inches
madreJ [45]
Compare the areas of the 2 different pieces of paper.

For the circle, the area is A=pi * r^2, which works out to A = pi(5 inches)^2.

For the square, the area is A = s^2, where is the side length, which here is 11 inches.

Finish these calculations, and then compare your two areas.  Which is the larger?

Graham drove 42 1/3 miles in 1 1/3 hours. A. How many miles did he drive in one hour?
Nonamiya [84]

change to  improper fractions

42 1/3

(3* 42 +1) /3 = 127/3

1 1/3 = (3*1 +1) /3 = 4/3

127/3 divided by 4/3

copy dot flip

127/3 * 3/4

127/4

31 3/4 miles per hour

He drove 31  3/4 miles in one hour

31 3/4 miles  1 mile

------------     = ------------

1 hours             x hour

using cross products

31 3/4 * x =1*1

x = 1/  127/4 (copy dot flip)

x = 1 * 4/127

x = 4/127

it takes 4/127 of 1 hour (approx .03 hours)
