Answer: 12 inches
Step-by-step explanation: There are 12 inches in 1 foot.
Total Time = (M x K) / (M + K)
5 = (8 x K) / (8 + K)
40 + 5 K = 8K
40 = 3K
King can do the job in 13.33 Hours
King could mow (1 / 13.33) of the lawn in one hour.
Subsitute -4y for x
-4y+6y=18
2y=18
divide both sides by 2
y=9
sub back
x=-4y
x=-4(9)
x=-36
(x,y)
(9,-36)
Answer:
Step-by-step explanation:
3. V triangular prism =B*h=18*12*35=7560 cubic feet
4. V cone= pi*r^2*h=pi*8^2*9=3.14*64*9=1808.6 cubic feet
5. V=B*h/3=15*9*13/3=5*9*13=585 cubic milimeters
