It would be 29 because 8hours - 45minutes =7hours 15 minutes
7hours 15minutes divided by 15 minutes =29
Answer: always decreasing
Step-by-step explanation:
Answer:
Step-by-step explanation:
f(x)= -4x+9 solve f(c+2)
f(c+2) = - 4 (c+2)+9 = -4c -8+9
f(c+2) = - 4c +1
Answer:
a = 7, b = 9 and c = 4.
Step-by-step explanation:
7 ^ (9/4)
= (7^9) ^ 1/4
= ⁴√(7^9)
so a = 7, b = 9 and c = 4.
Let
x--------> the total length of the water main
we know that
the number of 20 ft pipes is x/20
and
the number of 18 ft pipes is x/18
Since they differ by 14 pipes,
we have the equation
x/18 - x/20 = 14
Solve for x (by canceling fractions)
20x - 18x = 14*18*20
x = (14*18*20)/2
x = 2,520 ft
therefore
the answer is
the total length of the water main is 2,520 ft
