Mailing on a weekly salary of $385 plus a 70% commission on a sale at a gift shop how much would she make in a work week if she had sold for 4300 worth of merchandise

Answers

Answer:

Total Amount made by Mailing in a week is $3395.

Step-by-step explanation:

Given:

Fixed Salary = $385

Percentage of Commission on Sale = 70%

Total Sale = 4300

we need to find Total amount made by Mailing in a week.

We will first find the amount made on commission.

Amount made on commission  = (70)/(100) * 4300 = \$3010

Now Total Amount made by Mailing in a week is equal to sum of Fixed Salary and  Amount made on commission.

Framing in equation form we get;

Total Amount made by Mailing = $385 + $3010 = $3395.

Hence Total Amount made by Mailing in a week is $3395.

Solve this inequality: j/4 – 8 < 4. A. j < –48 B. j < 48 C. j > –12 D. j < 12

Answers

(j)/(4) - 8 \ \textless \ 4 \n \n (j)/(4) \ \textless \ 4 + 8 \n \n (j)/(4) \ \textless \ 12 \n \n j \ \textless \ 12 * 4 \n \n j \ \textless \ 48 \n \n

The final result is: j < 48.
j/4 - 8 < 4

j/4 < 4 + 8
j4 < 12
j < 12 X 4
j < 48

Perform each of the following conversions, making sure to use the correct abbreviations for units? A) 7.000 cubic centimeters to kiloliters B) 80. cm2 to inches2

Answers

A) To convert 7.000 cubic centimeters to kiloliters:

7.000 cm^3 * (1 kL / 1,000,000 cm^3) = 0.000007 kL

B) To convert 80. cm^2 to square inches:

80. cm^2 * (1 in^2 / 6.4516 cm^2) ≈ 12.44 in^2

If (m, 1) is on a circle with center (8, 1) and radius 7, what is a value of m?A)m=1
B)m=-1
C)m=14
D)m=-8=-+sqrt33

Answers

A) m=1

The equation for the circle is:

(x-8)^2 + (y-1)^2 = 49

If we take 'y' as 1, then

(x-8)^2 + 0 = 49

x-8 = √49

x = ±7 + 8

x = 15 or x = 1
