two sides of a rectangular fence are 5 5/ 8 feet long. the other two sides are 6 1/4 feet long. what is the perimeter
Levart [38]
Perimeter is how far around, so you are going to total the 2 lengths and 2 widths.  A way to write that is P=2l+2w.  

P = 2(5 5/8) + 2 (6 1/4)

2(5 5/8) = 10 10/8 or 11 2/8 or 11 1/4

2(6 1/4) = 12 1/2

P = 11 1/4 + 12 1/2

P = 23 3/4

$59.75 camera, 4% sales tax <br> please show in full detail
jek_recluse [69]

Answer:

The total cost would be: $62.14

Step-by-step explanation:

First convert the percent to a decimal, so since it is 4%, you move the decimal two places to the right, so it would be .04.

Next, multiply $59.75 x .04%.  This equals $2.39.

Then, take the product and add it to $59.75. So, $59.75 + $2.39.

This equals $62.14!
