Step-by-step explanation:

A quadrilateral measured 360. if you do not know that you can multiply 360 by 2 because there are 2 triangles in a quadrilateral. Then you subtract 360 by 75,115, and 90. And you will get 80 degrees

a wildlife photographer spent 5 minutes taking pictures of a bison at a park. when the bison then decided she didn't want her ph
ZanzabumX [31]

The percent of time the photographer spent negotiating with the bison greater than the time he spent taking pictures is 500%

<h3>Percentage</h3>

  • Time spent taking pictures = 5 minutes
  • Time spent negotiating = 30 minutes

Percentage of time negotiating greater than taking pictures = (difference in time) / time to take pictures × 100

= (30 - 5) / 5 × 100

= 25/5 × 100

= 5 × 100

= 500%

2) A salesperson earns commission on the sales that she makes each month.
mixer [17]
Part A
Commission total = Commission 1+ Commission 2
Where
Commision 1 = 5% of first 45000
Commission 2 = 7.5% of the amount left after $5000 is subtracted
thus 
Commision 1 = $5000x.05
                      = $250

Commission 2= $3000 x.075
                        = $225
Commission total = $250+$225
                              = $475
The total commission she earned is $475ion

Part B.
Total sales = Sales with 5% commission+Sales with 7.5% commission
Sales with 5%commission= $5000
Commision At 7.5% = Total commision -Commission with 5%
                           =    $1375-$250
              Sales x.075=  $1125
              Sales with 7.5% commision = $15000
Total sales = $5000+$15000
Total sales = $20000
Total sales for commission of $1375 is $20000
