To find g(f(4)), work from the inside out.

f(4) is 4^2+3, or 16+3, or 19.  Now, we must find g(19).

This is 19+5/19.  This is already a mixed number, though if you want an improper fraction solution, we have:

361/19+5/19

Which simplifies to:

366/19

Therefore, 366/19 is the answer.

Therefore,

1st angle = 51.67 degree

2nd angle = 58.67 degree

Shashi Rimoko earns $620 per week as a chef. He has group
finlep [7]

Out of the weekly amount that Shashi Rimoko makes, a deduction of $37.93 is made for insurance.

The total Medical cost is $9,560 and out of this, the amount paid by Shashi per year is:

<em>= Amount x (1 - percentage paid by restaurant)</em>

= 9,560 x ( 1 - 80%)

= $1,912

The amount he pays for Dental coverage is:

<em>= Amount x (1 - percentage paid by restaurant)</em>

= 172 x (1 - 65%)

= $60.20

The total amount he pays for insurance per year is:

<em>= Medical + Dental </em>

= 1,912 + 60.20

= $1,972.20

The weekly deduction is:

<em>= Year amount / No. of weeks in year </em>

= 1,972.20 / 52

= $37.93

In conclusion, $37.93 is deducted from his paycheck every week.
