Answer:
x = 33
Step-by-step explanation:
Two angles are complementary as the sum of two angles is 90
x + 24 + x = 90 {Combine like terms}
2x + 24 = 90 {Subtract 24 from both sides}
2x = 90 - 24
2x = 66
x = 66/2
x = 33
Answer:
31 animals
Step-by-step explanation:
1 rabbit + 6 elephants + 6*2=12monkeys + 12 parrots = 31 animals
You can use estimation.
80×130=10,400
Clearly 10,400 and 94 are way off.
Surface area = 2(ab+bc+ac)
a=5.2 ft, b=2.4 ft, c=3.5ft
Surface area = 2(5.2 * 2.4 + 2.4 * 3.5 + 3.5 * 5.2) =
2(12.48 + 8.4 + 18.2) =
2 * 39.08 =
78.16 ≈ 78.2 ft² ← <span>to the nearest tenth</span>
S(5) = -16*(5)*2 + 550 = 390
you just replace t with 5
