The Kirkland’s have a pool in their backyard that can hold a maximum of 4,500 gallons of water. The pool already contains 1,500 gallons of water. Mr. Kirkland begins to add more water at a rate of 30 gallons per minute. Write an inequality that shows the number of minutes, m, Mr. Kirkland can continue to add water to the pool without exceeding the maximum number of gallons.

Answers

Answer:30M + 1500 less than or equal to 4500

this should be the right awnser

Step-by-step explanation:

Answer:

100 minutes (or 1 hour and 40 minutes)

Step-by-step explanation:

to start I subtracted 4,500( how much it can hold) by 1,500 (how much it has already) to get 3,000.  

4500 - 1500 = 3000 (300 + 1500 = 4500)

so the pool would need 3,000 more gallons of water to reach the limit,

then divide 3,000 by 30 to know how many 30 gallows would be needed to reach the limit

3,000 ÷ 30 = 100 (100 x 30 = 3,00 so this is correct)


He would need to add water for 100m to avoid exceeding the limit.

That is as far as I know, you can utilize this problem to write an appropriate Inequality, I hope this is helpful!

Sally’s bank account has $650 in it. Every week sally withdraws $50 to pay for her dog sitter. What is the maximum number of weeks tajar sally can withdraw the money so that there is at least $75 remaining in the account? Write and solve an inequality to find the solution, and graph the solution on a number line.



Pls help 10 pts for this due tmrw!!!

Answers

Answer:11

Step-by-step explanation:I think

answer:  the maximum number of weeks Sally can remove $50 from the account and still have at least $75 is 11 weeks.

show my work :

Let W be the number of weeks Sally has been withdrawing money.  The total in the account would be represented by 650-50W at any given time.

To remain over or equal to $75 the equation to solve is

650 - 50W >= 75

we need to get the variable on one side and the constants on the other so subtract 650 from each side...

-50W >= 75-650

-50W >= -575

Now we need to divide out the coefficient of the variable so divide both sides by -50.   Note that multiplying or dividing an inequality by a negative reverses the inequality so...

W <= (-575)/(-50)

W <= 11.5

So in whole numbers the maximum number of weeks Sally can remove $50 from the account and still have at least $75 is 11 weeks.

[tex]m = \frac{4}{5}[/tex]

Step-by-step explanation:

Find the slope by using the slope formula:

slope [tex](m) = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (4 , 4)\\(x_2 , y_2) = (9 , 8)[/tex]

Plug in the corresponding numbers to the corresponding variables:

slope [tex](m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 - 4}{9 - 4}[/tex]

Simplify. First, subtract, and then simplify, if possible, the slope:

slope [tex](m) = \frac{8 - 4}{9 - 4} = \frac{4}{5}[/tex]

slope [tex](m) = \frac{4}{5}[/tex] is your answer.
