One scale factor equation is y=cx
y is the new factor    (in this case, 60 or 75)
c is the scale factor   (in this case, unknown)
x is the old factor      (in this case, 24 or 30)
so:   plug in the values
60=c(24)         divide both sides by 24
c=2.5

you can check again with the other numbers
75=c(30)           divide both sides by 30.
c= 2.5

your scale factor is 2.5

9. The experimental probability that it will rain on any given day in Houston Texas is about 15%. Thus, out of 365 days, 15% of that are the predicted days the it will rain in the Place. => 365 days is the total number of days in a year => 15% is the predicted days to rain => 365 * .15 = 54.75 Since this is a decimal number, let’s round this off to 55 days. Why 55 because the value of tenths is more than 5.

What is the radius of a circle with an area of 113.04 cubic inches? Use 3.14 for pi. Enter your answer in the box. in.
gizmo_the_mogwai [7]

Answer:

6 inches.  

Step-by-step explanation:

We have been given that area of a circle is 113.04 cubic inches and we are asked to find the radius of the circle.

We will use area of circle formula to find the radius of our circle.

\text{Area of circle}=\pi r^2

Upon substituting the area of given circle we will get,

113.04=\pi r^2

Substituting \pi=3.14 we will get,

113.04=3.14*r^2  

\frac{113.04}{3.14}=\frac{3.14*r^2}{3.14}  

36=r^2

Upon taking square root of both sides of our equation we will get,

r=\pm 6  

Since the radius of the circle can not be negative, therefore, the radius of circle will be 6 inches.
