d = distance between home and school

v₁ = average speed while going from home to school = 32 mph

t₁ = time taken to travel distance going from home to school

time taken to travel distance going from home to school is given as

t₁ = d/v₁

t₁ = d/32                                  eq-1

v₂ = average speed while going from school to home = 48 mph

t₂ = time taken to travel distance going from school to home

time taken to travel distance going from school to home is given as

t₂ = d/v₂

t₂ = d/48                                                     eq-2


t = total time of travel = 1 hour 15 min = 1.25 hour

total time of travel is given as

t = t₁ + t₂

using eq-1  and eq-2

1.25 = (d/32) + (d/48)

d = 24 miles

SSSSS [86.1K]

The answer to this question is 10 cm

In this question, you asked the height and given the volume of water(2400cm3), aquarium length(20cm), and aquarium width(12cm).

Then you need to divide the volume with the length and width. The equation would be:

Aquarium height= volume / length / width

Aquarium height= 2400 cm3 / 20cm / 12 cm = 10cm.

The table lists how financial aid income cutoffs (in dollars) for a family of four have changed over time. Use the midpoint form
Kipish [7]
You can see that every decade the income increases by 6,250. So if you want to do 5 years instead you would have to add 3,125 to the income of 1980 to find what the income was for 1985. Now you add 33,750+3,125= 36,875. The financial aid cutoff for 1985 would be $36,875.

The length of a screw produced by a machine is normally distributed with a mean of 0.65 inches and a standard deviation of 0.01
Makovka662 [10]
Notice it is +/-4 times standard deviation (0.65-0.04 = 0.61, 0.69-0.04=0.65)

That's almost everything. So (D) is the answer.
