Choose the correct expression to represent the situation: the cost of a telephone call is $1.25 plus 50 cents times the number of minutes (m). *
1.25 + 0.50m
1.25m + 0.50
1.25 + 0.50 + m

1.25 + 0.50m

Step-by-step explanation:

This is because 1.25 is the call fee plus 50 cents per minute, the word per is a key word for multiplication there for 50 times m so the equation is $1.25 fee + 0.50m

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
