The perimeter of the infield of a baseball field is
360 feet. If the length is 90 feet, what is the width
of the infield?

90 feet

Step-by-step explanation:

Because the infield of a baseball field is a square, the distance between each set of bases is equal.

P = 2l + 2w

360= 2(90) + 2w

360 = 180 + 2w

180 = 2w

90 = w

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
