Answer:
Step-by-step explanation:
The marked angles form a linear pair, so have a sum of 180°.
(4a +10) +(6a) = 180
10a = 170 . . . . . . . . . . subtract 10
a = 17 . . . . . . . . . . . . . divide by 10
__
Then the measure of angle ABC is ...
∠ABC = 4a +10 = 4(17) +10 = 68 +10 . . . . . substitute 17 for 'a'
∠ABC = 78°
It’s easy just find the slope and the answer is gonna be obvious
Slope= y2-y1/x2-x1
Slope = -2-(-1)/0-4 = -1/-4 = 1/4
Slope = 1/4x
So the answer should be C
Raw material for 500 units per week = 500 x $10 = $5000
Cost of hiring 20 workers per week = 20 x 40 x 25 = $12000
Rental = $2250
Total = 5000 + 12000 + 2250 = $19 250
