Answer:

15/10, 30/20, 60/40, 120/80, 240/160, 480/320

Step-by-step explanation:

The number of push-ups is 2/3 the amount of sit-ups, so the ratio of sit-ups to push-ups is 3:2.

The easy way to do this is to double both 15 and 10 so your answer will stay an equivalent ratio. You will always have a 3:2 ratio this way.

A circle with center on (7,0) with a radius of 9.
Greeley [361]

Answer:

The answer to your question is   (x - 7)² + y² = 81

Step-by-step explanation:

Data

Center = (7, 0)

radius = 9

Process

To find the standard equation of a circle, just substitute the values of the center and the radius.

Standar equation of a circle

                     (x - h)²  +  (y - k)² = r²

-Identify the values of h and k

                     h = 7    k = 0   and r = 9

-Substitution

                    (x - 7)² + (y - 0)² = 9²

-Simplification

                  (x - 7)² + y² = 81
