A swimming pool holds 250,000 gallons of water and is being drained at 200 gallons per minute. How many gallons remain in the pool after 5 minutes than after 20 minutes?

Answers

Answer:

After 5 minutes, the pool will hold 249,00 gallons of water.

After 20 minutes, the pool will hold 246,000 gallons of water.

After 5 minutes the pool will have 249,000 gallons since 5x200=1000 and 250,000-1000=249,000.
After 20 minutes it will be at 246,000 gallons since 20x200=4000 and 250,000-4000= 246,000.

x = 0 is a vertical line.

If a point is reflected across a vertical line, x-value becomes the distance from the reflection line and the sign changes most likely.

Thus if (-4,3) is reflected across a vertical line, its sign change and it becomes (4,3)

The answer is (-3,4) because mirrored give you -3 and then mirror the -4 and you get just 4

Youssef has $40 in his piggy bank and he spends $2 a day on a soft pretzel at lunch. Tiernan is selling his lunch each day at school to save up for an electric skateboard. After 3 days, he has a total of $22 and after 6 days he has a total of $34. In how many days will the two have the same amount of money?

Answers

Answer: 5 days

Explanation:
Tiernan
10 + 4d
10 + 4(5) = 30





Youssef
40 - 2d
40-2(3) = 34
40-2(4)= 32
40-2(5) = 30

They two shall have the same amount of $30 after 5 days

[Consider "d" is number of days, "y" is total amount]

For Youssef:

Starting amount = $40Spending amount = $2

1) Equation created: y = 40 - 2d ____ eq(1)

For Tiernan:

3 days = $226 days = $34

Unit rate: (change in amount)/(change in day) = (34 -22)/(6-3) = $4

2) Equation created:

y - 22 = 4(d - 3)y = 4d - 12 + 22y = 4d + 10 ____eq(2)

For them to have same amount, solve simultaneously:

4d + 10 = 40 - 2d4d + 2d = 40 - 106d = 30d = 30/6 = 5 days

Amount after 5 days: 4(5) + 10 = $30
