Anna wants to rent movies from either service a or service b. service a charges $37.92 as a subscription fee with a charge of $2.18 per movie. service b charges $33.25 as a subscription fee plus $3.55 per movie. service b is running a special offer where the first movie is free.

given that anna always rents at least 1 movie in a given subscription period, how many movies would she have to rent for the average cost per movie to be equal at service a or service b?
a.
6
b.
0
c.
1
d.
7

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
