If you have a square that has sides measuring 5 inches what is the measure of its diagonal​
Oxana [17]

Answer:

5√2 Inches

Step-by-step explanation:

By definition of a square, all it's sides are the same measurement (typically signified by the variable <em>s</em> on all sides).

In a triangle (as with a intersection from one corner to the other (diagonal), It would create a right triangle. Remember, the two leg sides are the same measurement (typically placed as 1). There is one triangle side measurement rule:

1 , 1 , √2

Plug in the corresponding numbers to the corresponding units. the 5 inches is a side (not the hypotenuse), so it belongs in the 1:

1 x 5 = 5

1 x 5 = 5

√2 x 5 = 5√2

The measurement of it's diagonal (hypotenuse) is 5√2.

Billy’s employer pays for 65% of his annual health insurance premium. Billy has the rest deducted in equal amounts from his payc
Alenkasestr [34]

Answer:

4712.54

Step-by-step explanation:

His total annual premium 4712.54 . Billy received the deducted by $105.73 paycheck, twice a month throughout the year, so he received 24 deducted paychecks in a year.  The sum of all the deducted $105.73 amount throughout the year will be the 35% of Billy's total annual health insurance premium.

To get the amount his employer contribute towards his health insurance on an annual basis, we will have to multiply the sum deducted by twice a month throughout the year in which he received deducted paychecks.    

105.73 * 24  = 2537.52

The next step is to divide our answer with 35% of Billy's total annual health insurance premium.  

x = 2537.52/.35

x = 7250.06

7250.06 * 0.65 = 4712.54
