belka [17]

A) Commission made last week is $ 288

B) Commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976

<em><u>Solution:</u></em>

From given,

Commission rate = 4 %

Last week,she sold $7,200 worth of stocks

<em><u>A. ) How much commission did she make last week?</u></em>

Therefore,

Commission\ amount = 4 \% of\ 7200\\\\Commission\ amount = 4 \% \times 7200\\\\Commission\ amount = \frac{4}{100} \times 7200\\\\Commission\ amount = 4 \times 72\\\\Commission\ amount = 288

Thus commission made last week is $ 288

B)

Given that,

If she were to average that same commission each week

To find the commissions earned in a year, treating a year as having exactly 52 weeks

Therefore,

commissions\ earned\ in\ a\ year = 288 \times 52\\\\commissions\ earned\ in\ a\ year = 14976

Thus commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976

Help please, also provide work
Andreas93 [3]

Answer:

9) 128
10) 78
11) 31
12) 148

Step-by-step explanation:


9) we know that the segment across from the angle 48° is double the angle.

48 · 2 = 96

The segments around the circle should all add up to 360 so we add the two segments we know to find the unknown segment.

136 + 96 = 232

360 - 232 = 128

The answer for 9 is 128.

10)

61 + 80 = 141

180 - 141 = 39

39 * 2 = 78

The answer for question 10 is 78.

11)

236 + 62 = 298

360 - 298 = 62

62 ÷ 2 = 31

The answer for question 11 is 31.

12)

50 · 2 = 100

100 + 112 = 212

360 - 212 = 148

The answer for question 12 is 148.
