The water is flowing into the pool at 1.5 gallons per minute and it would take 20 minutes to be filled.

An equation is used to show the relationship between two or more numbers and variables.

The pool holds 30 gallons of water. After 5 minutes, the pool is about one fourth full. Hence:

Time to full the pool = 5 minutes * 4 = 20 minutes

Rate of water flow = 30 gallons/20 minutes = 1.5 gallons per minute

The water is flowing into the pool at 1.5 gallons per minute and it would take 20 minutes to be filled.

Answer:

x = 12

Step-by-step explanation:

I am unable to decipher what "x = 9/36 x/48" means.

I'll assume that the question is to find a value of x such that:

   x/48 = 9/36

If so, cross multiply:

  36x = (48*9)

 36x =  432

  x = 12

Answer:

NVM MY BAD

x=19

quadrilateral have the internal degree sum of 360

not 365

Answer:

I'm not sure if you need the value of x or the entire angle measure, so I'll give you both.

x = 19

The angle measure is 46 degrees

Step-by-step explanation:

The sum of a quadrilateral's interior angles is 360 degrees. With that knowledge, we can subtract the angle measures we have from 360. To do that, we must first add 115 + 118 + 81, which equals 314. Now, we do 360 - 314, which gives us the measure of the unknown angle, which is 46 degrees.

Now, we must find x. We write the equation 2x + 8 = 46 since we know what the angle measure is now. Then, we subtract 8 from both sides, which leaves us with 2x=38. Finally, we need to divide 2 on both sides. If your math is correct, you should end up with x = 19. Hope this helps!

Answer:

4.4

the only thing that goes in 22 and 5 is 4 and 2 is going to remain because 5 times 4 is 20 so after that add a decimal after the 4 and add a zero next to 22 and bring it down to the 2 so noe the 2 turns into 20 sense 20 goes in 5 4 times the answers is 4.4.

Answer:

She'll need 3 more hours to complete the project

Step-by-step explanation:

Because (3/4) × (4/3) = 1, you can multiply 9 by 4/3 to find the total amount of time needed for the project. You'll get a total time of 12 hours. To find how many more hours needed you would do 12 - 9 = 3 hours

Answer: You simply need to match each fraction to where they belong

Step-by-step explanation:

Answer:

  B

Step-by-step explanation:

The dimensions of A and B are, respectively, (3, 2) and (2, 2). This means the dimensions of the product will be (3, 2), the same as A. This eliminates answer choices A and C immediately.

__

To determine whether the answer is B or D, find a term in which those matrices differ. Then compute that term from A and B.

Here, term (1, 2) is -37 in choice B and -32 in choice D. The actual product term is the dot product of row 1 of A and column 2 of B:

  [1, -4]·[7, 11] = (1)(7) +(-4)(11) = 7 -44 = -37 . . . . matches choice B

__

Your scientific or graphing calculator can probably compute the matrix product for you. Certainly, any spreadsheet can, as shown in the attachment.

Step-by-step explanation:

The rate of decay r is -0.139.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The exponential function [tex]y = 3.31(0.87)^x[/tex] can be written in the form

[tex]y = ab^x,[/tex]

where a = 3.31 and b = 0.87.

The formula for the rate of decay for an exponential function in the form

[tex]y = ab^x[/tex]is r = ln(b)

where ln is the natural logarithm.

In this case,

r = ln(0.87) ≈ - 0.139.

Since r represents the rate of decay as a decimal, the answer is r = - 0.139.

Thus,

The rate of decay r is - 0.139.
