Answer:

  • h =  V/πr²
  • h = 10 inches

Step-by-step explanation:

  • V = πr²h

<u>1. Solving for h:</u>

  • V = πr²h
  • πr²h = V
  • πr²h/πr² = V/πr²
  • h =  V/πr²

<u>2. Finding the height of given cylinder, using formula above:</u>

  • V = 90π, r = 3 inches, h = ?
  • h =  V/πr²
  • h = 90π/π3²
  • h = 10 inches

How do you find a variable to 4-2(v+9)=26
garik1379 [7]

Answer:

V=20

Step-by-step explanation:

Simplify both sides of the equation.

4−2(v+9)=26

4+(−2)(v)+(−2)(9)=26(Distribute)

4+−2v+−18=26

(−2v)+(4+−18)=26(Combine Like Terms)

−2v+−14=26

−2v−14=26

Step 2: Add 14 to both sides.

−2v−14+14=26+14

−2v=40

Step 3: Divide both sides by -2.

−2v

−2

=

40

−2

v=−20

Dave surveyed 80 7th-graders and 90 8th-graders. He found that about 75% of the 7th-graders like pop music, while 80% of the 8th
dimaraw [331]

<u>8th Grade: </u>90 x 0.80 = 72

<u>7th Grade:</u> 80 x 0.75 = 60

Conclusion: 8th Graders like pop music more because 72 out of the 90 in 8th grade Dave surveyed enjoy it, compared to the 60 out of 80 in 7th grade that enjoyed it.

(x-1)(x+2)=5(x-1) divided by x-1
anyanavicka [17]
Assuming that your question is (x-1)(x+2) = [5(x-1)]/x-1

On the right side, the x-1's will cancel out, leaving you with (x-1)(x+2) = 5

expand the left side, giving you x^2 + x -2 = 5
which goes to x^2 +x -7 = 0
the possible values for x are 2.93 and -3.93. I don't think this was your question, so I'll do the other possible question that you might have been asking.

(x-1)(x+2) = 5(x-1)

divide by x-1 on both sides, leaving you with x+2=5
x+2=5
x=5-3
x=3
