cara works at a fine jewelry store and earns a commission on her total sales for the week. her weekly paycheck was in the amount

Gekata [30.6K]

Cara's rate of commission is 12%.

Step-by-step explanation:

Given,

Paycheck = $6500

Salary = $1000

Commission = Paycheck - Salary

Commission = 6500-1000 = $5500

Total sales for the week = $45000

Commission rate = $\frac{Commission}{Total\ Sales}*100$

$Commission\ rate=\frac{5500}{45000}*100\\\\Commission\ rate=\frac{550000}{45000}\\\\ Commission\ rate=12.22\%$

Rounding off to nearest whole number.

Commission rate = 12%

Cara's rate of commission is 12%.

A regular hexagon has an apothem of 14. 7 inches and a perimeter of 101. 8 inches. What is the area of the hexagon?.

AleksAgata [21]

Answer:

748.23 in²

Step-by-step explanation:

<u>Area of a Regular Polygon</u>

$\textsf{Area of a regular polygon}=\dfrac{n\:l\:a}{2}$

where:

n = number of sides
l = length of one side
a = apothem

Given:

n = 6
l = 101.8 ÷ 6
a = 14.7

Substituting the given values into the formula and solving for A:

$\implies \textsf{A}=\dfrac{6 \cdot \dfrac{101.8}{6} \cdot 14.7}{2}$

$\implies \sf A=\dfrac{101.8 \cdot 14.7}{2}$

$\implies \sf A=\dfrac{1496.46}{2}$

$\implies \sf A=748.23$

Therefore, the area of the hexagon is 748.23 in²
