Her regular weekly pay is $62 and her annual salary is $3100.
Step-by-step explanation:
Given that her hourly wage=$15.50 / hour
As she works 40 hours per week, so her weekly pay = 15.50 x 40 = $62/ week.
If she works 50 weeks each year, so her yearly pay = 62x50=$3100 /year.
Hence, her regular weekly pay is $62 and her annual salary is $3100.

Step-by-step explanation:
Answer:
0.7, 7/8, 1 7/10, 1.78
Step-by-step explanation:
Use a calculator to find the decimal value of each fraction and put the decimals in order.
We are given : Number of diagonals of a polygon = 1127 diagonals.
We know relation between number of diagonals and number of sides of the polygon.
<h3>
, Where n is the number of sides of the polygon and d is number of diagonals.</h3>
Plugging d=1127 in above formula, we get
Multiplying both sides by 2, we get
Solving quadratic equation by factoring, we get factors
Solving for n, we get
n-49=0
n=49.
n+46=0.
n=-46.
We can't take number of sides by a negative number.
Therefore, number of sides does the polygon have 49 side.
