Part b
8.
the home builder is now planning the size of a food pantry. the floor of the pantry will
have an area of 24 square feet and a perimeter of 20 feet.
what will be the length and width of the floor of the pantry?
a
width = 3 feet, length = 8 feet
width = 4 feet, length = 6 feet
width = 5 feet, length = 5 feet
width = 7 feet, length = 3 feet

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

3x + 4y -25 =0 represents the amount of change sianna should recieve

the answer is 13/48
