Answer:
10 months. Each plan will save 800 dollars.
Step-by-step explanation:
500 + 30x = y
300 + 50x = y
You want the months to give the same amount of money. The x has to be the same for both
500 + 30x = 300 + 50x Subtract 300 from both sides
500 - 300 + 30x = 50x Combine
200 + 30x = 50x Subtract 30x from both sides
200 = 50x - 30x Combine
200 = 20x Divide by 20
x = 10
So in 10 months time the amounts will be the same. How much will there be?
500 + 30*10 = 500 + 300 = 800
300 + 50*10 = 300 + 500 = 800
Y2-y1 / x2-x1
so, 3-1 =2 and 4-3=1
2/1 is 2
Answer:
25.50 depending on what you rounding to
Step-by-step explanation:
.
1st : Find the volume of the rectangular block:
12 × 10 × 20 = 2400 cm^3.
2nd : Find the volume of a cylinder

Where r is radius & h is height.
so:

= 76.02654222 cm^3
Lastly, divide the volume of the rectangular block by the volume of the cylinder
2400 ÷ 76.026 = 31.5679226
You can't round it up so the answer is F) 31
