Answer:

c) 12/15 = 4/5

Step-by-step explanation:

imagine we mirror the triangle up, so that Z is on top.

then you can clearly see that 6 is cos(X) times r (and r is then 7.5).

XY is sin(X)×7.5

and again, 7.5 is r (the line making the X angle).

so, the cosine ratio of X is

6 = cos(X)×7.5

cos(X) = 6/7.5 or then 12/15. or simplified 4/5.

A salesperson at a jewelry store earns ​5% commission each week. Last​ week, Jarrod sold $640 worth of jewelry. How much did he
Aleksandr-060686 [28]

He made $32 in commission.

<em>Additional comment</em>

Many calculators and all spreadsheets can work with percentages directly. If yours can't, or if you can't do this arithmetic mentally, you can use the equivalent decimal or fraction for 5%.

  5% = 5/100 = 0.05 = 1/20

Then 5% × $640 = $640/20 = $64/2 = $32.

She earned 1149, which is between 436 and 1506 so you would use the 2nd row for the information.

the tax rate says 15% for the amount over 436
 so fist find the amount that is taxable:

1149 - 436 = 713
 now multiply that amount by 0.15 ( 15% as a decimal)

713 * 0.15 = 106.95

now add the base tax to that amount for the total amount of tax:  
106.95 + 34.90 = 141.85 total tax withheld
