Rate of flow of water in the fish tank will be given by:
rate=volume/time
the rate of our tank is 15 gallons every 10 minutes. Thus,
rate=15/10=1.5 gallons/ minute
Therefore time taken for the tank to overflow will be:
time=volume×rate
volume of the tank=315 gallons
rate=1.5 gallons per minute
hence:
time=315×1.5
=472.5 minutes
=7 7/8 hours=7.875 hours
Answer:
450 cm^3 (Answer D)
Step-by-step explanation:
Volume of a rectangular box of dimensions L, W, H is V = L*W*H. The order in which these measurements are multiplied together is immaterial. Thus,
this particular box has volume V = (5 cm)(9 cm)(10 cm) = 450 cm^3
Recall that
is only defined for
, and under this condition we have that
. But 1.7 > 1, so
is not a real number.
Answer:
y = 2x + 11
Step-by-step explanation:
Parallel means the two lines have the same slope. The slope = 2 because the two is in front of the x. Whatever number is in front of the x is the slope.
So far what you know is
y = 2x + b
The point (-3,5) is what you need to get b.
y = 2x + b
y = 5
x = - 3
5 = -3(2) + b
5 = -6 + b
b = 5 + 6
b = 11

Equation
y = 2x + 11
