Answer:
6. 175/125=x/100
Cross products equal 125x=17500
Solve for x and you get 140%
7. 20% of 720 is 144. You need to find 120% so add the full 720 (100%) to the 144 and you get 864 (120%)
Step-by-step explanation:
Hello!
You find the volume of a rectangular prism if the length is x, the width is x2, and the height is 5x2 + 4x + 1. Use the formula
<span>V = l ⋅ w ⋅ h, where l is length, w is width, and h is height, to find the volume.
</span>
Solution:
So in this Case, we can see that the Length = x, Width = x², and Height = 5x2 + 4x + 1. Remember: (V = l . w . h)<span>
Use the formula:</span>
<span>V = l ⋅ w ⋅ h,=x×x²×(5x²+4x+1)
</span>
<span>=x³×(5x²+4x+1)
</span>
=5x^5+4x^4+x³

Inversely proportional: z = k/r
k = 32 * 1.5 = 48
Plug that into equation
8 = 48/r
Multiply both sides by r
8r = 48
Divide by 8
r = 6
Answer:
Step-by-step explanation:
Let t represent the number of hours of lessons Audrey can take. Then 15t will be the cost of the lessons. Her total cost will be ...
15t +45 = 120 . . . an equation
15t = 75
t = 5
Audrey can afford 5 hours of lessons.
