<u>Part a)</u> Create an equation that shows the amount of money earned, E, for working x hours in a week when there is no overtime
Let
E-------> the amount of money earned
x------> number of hours worked
we know that
For 

therefore
<u>the answer part a) is</u>

<u>Part b) </u>Create an equation that shows the amount of wages earned, T, for working y hours of overtime
Let
T-------> the amount of money earned
y------> number of hours of overtime
we know that


therefore
<u>the answer part b) is</u>

<u>Part c)</u> Allison earned $610 in 1 week. How many hours (regular plus overtime) did she work?
we know that


Divide
by
----> to obtain the hours of overtime

So
Allison works


therefore
<u>the answer part c) is</u>

1 / cos^2 O - 3 / cos O - 2 = 0
1 - 3 cos O - 2 cos^2 O = 0
2 cos^2 O + 3 cos O - 1 = 0
cos O = 0.2807 , -1.78 ( -1.78 cannot be a solution)
O = 74 degrees (from 0.2807) another solution is 360-74 = 286 degrees
Its D
Answer:
2250 ml
Explanation:
1 day = 0.45 L
5 days = 0.45 x 5
=2.25 L
1 L = 1000 ml
2.25 L = 2250 ml
