Answer:
h = -2
Step-by-step explanation:
subtract 5 from both sides (5-8h-5=21-5)
simplify (-8h=16)
divide both sides by -8 (both -8's cancel, leaving 16/-8 which is -2.)
I think it is D but i am not too sure
I’m pretty sure it’s the last one! :)
Answer:
r = 1.68 ft
Step-by-step explanation:
Volume of a sphere, V = 4/3πr³
V = 20 ft³
π = 3.14
r = ?
V = 4/3πr³
20 = 4/3 × 3.14 × r³
20 = (4×3.14×r³)/3
Cross product
20 × 3 = 4 × 3.14 × r³
60 = 12.56r³
r³ = 60/12.56
= 4.7771
r = 3√4.7771
= 1.6842
Approximately
r = 1.68 ft to the nearest hundredth
