Answer:
x=10
Step-by-step explanation:
x^2 + 24^2 = 26^2
x^2 + 576 = 676
x^2 = 100
√x^2 = √100
x=10
So with this equation, since the volume of the cylinder is 96 pi, plug that into the V variable, and since the radius of one of the marbles is 3, plug that into the r variable. From here, we can solve for x:
Firstly, solve the parentheses:
Next, multiply 36 pi and x:
Next, subtract 24 pi on both sides:
Lastly, divide both sides by 36 pi, and your answer will be , or B.
Answer:
Step-by-step explanation:
Let the number of weeks be x
<u>Then Kendal's CD's</u>
<u>Raymond's CD's</u>
<u>Time when they have equal CD's</u>
- 39 + x = 15 + 3x
- 3x - x = 39 - 15
- 2x = 14
- x = 7 weeks
Answer: 89
