S_A_V [24]

In this question, you are given the width( 20 miles), the length(28 miles) and the height( 1 inch). You are asked to count the rain water volume which was going with formula length x width x height. But the unit asked is ft, so you need to convert them all. The calculation would be:

Water volume= length x width x height
Water volume= 20 miles x 5280ft/miles x 28 miles x 5280ft/miles x 1inch x 1ft/12inch
Water volume = 1300992000 cubic ft.

fabiana decides to save the money she is earning from her after school job for college. she makes an initial contribution of 300

Oxana [17]

Answer:

A. Total Money Contributed after n months = $\$ 3000 + \$ (500\times n)$

B. Total Money Contributed after 24 months = $\$ \ 15000$

Step-by-step explanation:

Given:

Initial contribution = $\$\ 3000$

each month contribution = $\$\ 500$

After 1 month contributed = $\$\ 3000 + \$\ 500 \times 1= \$ \ 3500$

Solving for Part A

let n be the number of months

∴ Total Contribution after n months = Initial contribution + (each month contribution $\times$ Number of months = $\$\ 3000 + \$\ 500 \times n$

Solving for Part A

Now n= 24 months

∴ Total Contribution after 24 months = $\$\ 3000 + \$\ 500 \times 24 = \$\ 3000 + \$\ 12000= \$\ 15000$
