Volume formulas:
rectangle prism: l×w×h
cube: s^3
cylinder:(pi)r^2×h
triangle prism: (a×b/2)×h
cylinder:(pi)r^2×h
box:l×w×h
40) 5m×3m×4m =15m×4m= 60m^3
41) 6 ft × 6 ft ×6 ft = 36 ft × 6 ft = 216 ft^3
42) d=2r 10/2=5 r=5
3.14×5^2×14=78.5×14= 1099cm^3
43) 15=a×b/2 (area of trianlge)
15×12= 180in^3
44) c=2 (pi)r 8pi=2r (pi)
r=4
3.14×4^2×7=50.24×7=351.68
45) 24 ft^3 =2 ft × 3 ft × height
24=6×h
÷6 both sides
h=4ft
Answer:
73.5
Step-by-step explanation:
y=kx
where k is a constant
y=7
x=2
7=2k
k=3.5
what about when x=21
y=3.5*21
y=73.5

Answer:
The answer is A.
Step-by-step explanation:
To find the value you have to know how many hours the repairman took to repair. Then after you find how many hours he took multiply the hours by 35 than add 25.
So the equation would look like 35x hr+25 =
hr=hours
