Answer:

w = 9

m <4 = 157

m<2 = 23

Step-by-step explanation:

The measure of the arc of a straight line is 180⁰.

so angle 1 + angle 3 = 180⁰.

(3w - 4) + 157 = 180

3w = 27

w = 9

Finding the rate of a tax or commission
Ksju [112]

Answer:

The commission rate in percentage = 16%

Step-by-step explanation:

Given

Commission Amount = $352

Sales Price  = $2200

To determine

Find the commission rate in percentage.

Using the formula

Commission percentage = Commission Amount / Sales Price

substituting Commission Amount = 352 and Sales Price  = 2200

                                          = 352 / 2200

                                          = 0.16

Multiply by 100 to get the percentage:

0.16 × 100 = 16%

Therefore, the commission rate in percentage = 16%

louine bought a computer for 180$ and paid 10.80$ what percent of the cost is the sales tax? (Please help and explain)
leonid [27]
6%
to find the percentage you divide 10.80$ by 180$ and get 0.06
0.06 is 6% in decimal form 
therefore there was 6% sales tax (sales tax is usually 6-8% so this makes sense anyway)
