If the ratio of the dimensions is 4:7 and the shorter dimension is 10ft, we know that the 10ft corresponds to the 4 in this scenario. We can set up the equation as follows:

You have to multiply by 2.5 to get from 4 to 10. And since we want to make sure we are maintaining the ratio, we have to multiply the denominator, 7, by 2.5 as well.

This means your shorter side has a length of 10ft and your longer side has a length of 17.5ft.
AREA
The formula for the area of a rectangle is: 
So we can plug our dimensions into the formula: 
So 175 is our area. But we can't forget about units! Since this is area and we multiplied our units together, our units would be squared. That means our answer is <u>175 square feet</u>.
PERIMETER
The formula for the perimeter of a rectangle is: 
We can plug our dimensions into the formula: 
So 55 is our perimeter. Of course, we can't forget about our units. Because this is perimeter, we only added our units together, so they don't change. That means our answer is <u>55 feet</u>.
Answer:
See attached photo.
Step-by-step explanation:
y=-5x^2+10
Real distance of Earth from Sun . . . 93 million miles
= 1 AU (Astronomical Unit)
10 times farther . . . . . 930 million miles = 10 AU
Compare:
==> Saturn . . . 9.5 AU
==> Uranus. . 19.2 AU
If Earth were 10 times farther from the sun than we really are,
then our planet would be just barely past Saturn ... about 10%
of the way from Saturn to Uranus.
Answer:
The correct answer is 17.96875 or approximately 18 inches.
Step-by-step explanation:
Since the ratio of the model truck to the real truck is 5:64, and the length of the truck is 230 inches, that means the length of the model truck would be
=
= 17.96875 ≈ 18 inches.
I think it would be the last one because the top ones doesn't match up to the answer
