Tina is saving to buy a notebook computer. She has two options. The first option is to put $500 away initially and save $30 ever

r-ruslan [8.4K]

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

Can someone help with this question

NikAS [45]

1st : Find the volume of the rectangular block:
12 × 10 × 20 = 2400 cm^3.

2nd : Find the volume of a cylinder
$\pi {r}^{2} h$
Where r is radius & h is height.
so:
$\pi \times 2.2 {}^{2} \times 5.0$
= 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
