The ratio of width to length will be the same  so

4/7 = 16/l
l = (7*16) / 4 = 7 * 4 = 28

length = 28 inches

You want to buy an item that costs $100. Which of these is the most cost-effective choice for buying the item?. a. using a paid
Paraphin [41]

<u>Answer</u>

c. buying it at a 10 percent discount without sales tax.


<u>Explanation</u>

We are going to compare the 3 choices and then determine the most cost effective.

<em>a. using a paid membership card to buy it at a 10 percent discount.</em>

10% of $100 = 10/100×100 = $10

cost = $100 - $10 = $90

On top of this $90 there is the charges of the membership card.

<em> b. buying it online at a 10 percent discount with a $5 shipping charge.</em>

100%-10% = 90%

90% of 100 = $90

Cost: $90 + $5 = $95

<em>c. buying it at a 10 percent discount without sales tax.</em>

100% - 10% = 90%

90/100 × 100 = $90. This is the must cost effective method since there is no other cost involved.

WHAT IS 18 TONS 42 POUNDS DEVIDED BY 3
Alecsey [184]

A ton is 2,000 pounds so multiply 2,000 x 18

2,000 x 18 =  36,000 pounds, now add the 42 pounds to the 36,000

36,000 + 42 = 36,042 pounds. Now divide 36,042 by 3

36,042 ÷ 3 = 12,014

Your answer is 12,014 pounds

If you need your answer in tons it's 6.007 tons

Calculations for pounds to tons

12,014 ÷ 2,000 = 6.007

Hope this helps. :)
