Answer:
Your answer is about 12.48
Step-by-step explanation:
h = 3(V/pi*r²)
h = 3(640.23/pi*7²)
h = 3(640.23/153.93804)
h = 3(4.157516881)
h = 12.47703
Answer:
$50.50 = 18 + 5n
Step-by-step explanation:
Step-by-step explanation:
(i). a+(b+c) = (a+b)+c
-35+(10-5) = (-35+10)+(-5)
-35+5 = -25-5
-30 = -30
(ii). a×(b+c) = a×b + a×c
-35 × [10+(-5)] = -35×10 + -35×-5
-35 × (10-5) = -350 + 175
-35 × 5 = -350 + 175
-175 = -175
