Jason ran 4 miles in 30 minutes. which of the following is an equivalent rate of running?
a. 6 miles in 50 minutes
b. 3 miles in 20 minutes
c. 10 miles in 75 minutes d. 8 miles in 80 minutes

c

Step-by-step explanation:

30 divided by 4 = 7.5

75 divided by 10 = 7.5

The answer is C. Jason goes 2 miles per every 15 minutes. If Jason goes 10 miles you would multiply 15 by 5 and that is 75.

i think it would be 42cm

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
