pool has 45000 gallons.  It loses 780 gallons per hour, so the amount at any given time:

45000 - 780h, where h is the number of hours.

The chemical could be added once the amount of gallons in the pool hits 15000. So the equation to solve:

45000 - 780h = 15000

solve:

30000 = 780h

38.46 = h

It will take about 38.46 hours before chemical could be added.  It will not take longer than 2 days because 2 days is 48 hours, and we only need about 38 hours.

What is the length of SR?<br><br><br> 18 units<br><br> 9 units<br><br> 12 units<br><br> 15 units
Serjik [45]

Answer:


Step-by-step explanation:

RT = sqrt(20^2 - 16^2)

RT = sqrt(400 - 256)

RT = sqrt(144)

RT = 12


SR/ST=  QR/QT

SR/12 = 20/16

SR = 12 x 20 / 16

SR = 240/16

SR = 15


answer is C.

15 Units

Can 1,1,2 be the length is a triangle
Sholpan [36]
Alright, so in order to find this, you will nee to use the Triangle Inequality Theorem.
We’ll make the values = to variables to make it easier. a=1 b=1 c=2
All of the inequities need to be true.
a+b>c
b+c>a
c+a>b
Now replace the variables.
1+1>2 2>2 (False)
1+2>1 3>1 (True)
1+2>1 3>1 (True)
Since one is false, 1,1, and 2 cannot make a triangle.

Jake has two pet guinea pigs named fluffy and scruffy. Fluffy is8 1/8 inches long. Scruffy is 10 1/4 inches long. How much longe
miss Akunina [59]

Answer:

Scruffy is 2\frac{1}{8} inches longer than Fluffy.

Step-by-step explanation:

Length of Scruffy = 10\frac{1}{4} inches

Length of Fluffy = 8\frac{1}{8} inches

We have to calculate how much Scruffy is longer than Fluffy.

Difference of their lengths = 10\frac{1}{4}-8\frac{1}{8}

                                            = (10 - 8) + (\frac{1}{4}-\frac{1}{8})

                                            = 2 + (\frac{2-1}{8})

                                            = 2 + \frac{1}{8}

                                            = 2\frac{1}{8} inches

Therefore, Scruffy is 2\frac{1}{8} inches longer than Fluffy.
