The circumference of the circular table on colton’s porch is 72π inches. what is the radius of the table

Step-by-step explanation:

The formula for circumference is: C = 2πr

π = 3.14

r = radius.

The Circumference given to us is 72π. Plug in 72π for C

72π = 2πr

Isolate the variable, r. Divide 2 and π from both sides

(72π)/2π = (2πr)/2π

r = (72π)/2π

r = 36

36 in. is your answer

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
