Answer:
40%
Step-by-step explanation:
18/45 × 100
2/5 × 100
40%
Answer:
B
Step-by-step explanation:
5a^2 - 44 = 81 Add 44 to both sides
5a^2 = 81 + 44 Collect like terms
5a^2 = 125 Divide both sides by 5
a^2 = 125/5
a^2 = 25 Take the square root of both sides
√a^2 = √25
a = +5
a = -5
The answer is B

Answer:
469.42 ft²
Step-by-step explanation:
w/sin27 = 38/sin40
w = sin27*38/sin40
w = 26.84 ft
∡X = 180 - 27- 40 = 113º
A = 0.5*(26.84)*(38)*sin(113)
A = 469.42 ft²
