1. Cell phone bills are based on a flat monthly fee and the number of minutes used. In the equation c= 0.07m +29.99, what does the
variable m represent?
a. The number of months billed.
b. The total amount of the bill.
c. The number of minutes used.
d. The phone number.

answer: 12

step-by-step explanation:

because yes

if i put something wrong your not gonna like it so rather not say nothing.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
