Let the reduced price be x

If he paid for 6 rounds, he paid 1 round at full price of $19 and 5 rounds at reduced price:
19 + 5x = 59
5x = 59 - 19
5x = 40
x = 40 ÷ 5
x = 8

The reduced price is at $8 per round.

Alexus [3.1K]

Answer:

A. 4.40 square units

Step-by-step explanation:

The triangle is isosceles with base angles of 70°. The a.pex angle will be ...

180° -2(70°) = 40°

The area of a triangle can be computed from two sides and the angle between them as ...

A = (1/2)ab·sin(γ)

A = (1/2)(3.7)(3.7)sin(40°) ≈ 4.40 . . . square units
