The answer is B 10(3+4) since 10 times 3 is 30 and 10 times 4 is 40 and this is 30+40
Answer:
Head: 113.04 in³
Basketball: 33.5 in³
Step-by-step explanation:
suppose Ronnie's head and basketball are spheres
V = 4/3πr³
Head: V₁ = 4/3 * 3.14 * 3³ = 113.04
Basketball: C = 2πr
r = C / 2π = 12.57 / 6.28 = 2.00 (it's a small ball :))
V₂ = 4/3 * 3.14 * 2³ = 33.49
8a - 1 + 0.5b = 8(1/4) - 1 + 0.5(10)
= 2 - 1 + 5
= 1 + 5
= 6
10*9=90
10+10+9+9=38
90-38=52
52 tiles
and 38 feet of base board
9⁹ ÷ 9⁶.
The expression 9³ is equivalent to 9⁹ ÷ 9⁶.
Using the law of exponents aⁿ÷aˣ = aⁿ⁻ˣ
9⁹÷9⁶= 9⁹⁻⁶ = 9³
