Step-by-step explanation:
Answer:
1047.2 cubic inches
Step-by-step explanation:
V = 4(pi)(r³/3)
V = 4(pi)(125/3)
V = 523.6 cubic inches (1 ball)
V = 2(523.6) = 1047.2 cubic inches (total)
Answer:
x=-23
Step-by-step explanation:
-3.8x-5.9x=223.1
-9.7x=223.1
x=223.1/-9.7
x=-23
Answer:
Her test score would be an 85 because 5x3=15 and then you would subtract 15 from 100 which would be 85
equation would be x=100-(5y)
