A dilation produces a smaller figure. Which is a possible scale factor? –2 One-third 1 4

Ghella [55]

Answer:

1/3 (one-third)

Step-by-step explanation:

A scale factor that produces an image smaller than the original figure is less than 1. A scale factor that produces an image bigger than the original figure is more than 1.

Thus, the only option that's less than 1 is one-third.

You are running a fuel economy study. One of the cars you find is blue. It can travel 44 and one half miles on 1 and one fourth

Radda [10]

Unit rate of blue car is 35.6 miles/gallon and unit rate of red car is 36 miles/gallon. The red car could travel the greater distance on 1 gallon of gasoline.

Explanation

Unit rate for each car can be calculated using the below formula...

Unit rate = (Distance traveled) / (Amount of gasoline)

For Blue car, distance traveled $=44\frac{1}{2} = \frac{89}{2} miles$ and amount of gasoline $=1 \frac{1}{4}= \frac{5}{4} gallons$

So, the unit rate for blue car = $\frac{89}{2}$ ÷ $\frac{5}{4}$ = $\frac{89}{2}$ × $\frac{4}{5}$ = $\frac{356}{10} = 35.6$ miles/gallon

Now for Red car, distance traveled $= 28\frac{4}{5} = \frac{144}{5} miles$ and amount of gasoline $= \frac{4}{5} gallons$

So, the unit rate for red car = $\frac{144}{5}$ ÷ $\frac{4}{5}$ = $\frac{144}{5}$ × $\frac{5}{4}$ = $\frac{144}{4} = 36$ miles/gallon

As the unit rate for red car is greater than the blue car, that means the Red car could travel the greater distance on 1 gallon of gasoline.
