I’m not sure but i think 66 hours because both pumps must fill half of the pool which would split the timing for each which would make pump 1 take 36 hours to fill half and pump two take 30 hours to fill the rest. when you add these hours it equals 66. i hope i helped :)

Can somebody help me with this question, please? I have no idea how to do this or find the answer. :/ How many ways are there to
san4es73 [151]

Answer:

28 different ways

Step-by-step explanation:

This is a combination question. Combination has to do with selection.

Total number of element in the set = 8

Number divisible by 6 or 8 are {-98, -48, -42, -36, -18, -6}

Total number divisible by 6 or 8 is 6

The number of ways we can choose 6 items from 8 is expressed as;

8C6 = 8!/(8-6)!6!

8C6 = 8!/(2)!6!

8C6 = 8*7*6!/2!6!

8C6 = 8*7/2

8C6 = 56/2

8C6 = 28 ways

Hence there are 28 different ways

Using substitution, determine the solution to the system of equations. Include a photo of your work
kiruha [24]

Answer:

I can't submit a photo but here:

x = 4, y = 16

(4,16)

You can choose whichever format

Step-by-step explanation:

We have x given to us already. Since we know the value of x, we can input the value into the other equation to solve for y

Solve:

Substitute 4 for x:

  • y = 2x + 8
  • y = 2(4) + 8
  • y = 8 + 8
  • y = 16

Our solution is x = 4 and y = 16, or (4,16)
