<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. (3 points)
x hours in a week and there is no overtime and x <= 35 so equation:
E(x) = 16x
<u>Part B:</u> Create an equation that shows the amount of wages earned, T, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 35 hours. (3 points)
Regular hours = E(x) = $16 x 35 = $560
T(y) = 21y + 560
<u>Part C:</u> Marco earned $602 in 1 week. How many hours (regular plus overtime) did he work? Show your work. (4 points)
21y + 560 = 602
21y = 42
y = 2
Marco worked 37 hours (35 regular plus 2 hours overtime)
Answer:
Mean = Mean is all of the numbers added up and divided by the amount of numbers you have added up. Therefore its 414 ÷ 15 = 27.6
Mode = Most common number = 35
Range = Largest number - Smallest number
40 - 5 = 35
Median = 32 (Middle number)
Answer:
18 units^2
Step-by-step explanation:
There are two trianges each with a base of 3 and a height of 3, making each 4.5 units^2 and together, 9. Add the area of the triangles with the square to get 18.
Answer:
80 units ^2
Step-by-step explanation:
The semicircle that is added on to the rectangle can be translated to fit into the slot where a semicircle has been removed (both semicircles are congruent as they have the same diameter). This leaves us with a plain rectangle, with area b * h, or 8 * 10, or 80.
