Answer:
A
Step-by-step explanation:
90/2 = 45
45/2 = 22.5
Using linear function concepts, it is found that consumption would increase by $800.
<h3>What is a linear function?</h3>
A linear function is modeled by:

In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem, the function is given by:
C = 200 + 0.8Y.
Which means that the slope is of m = 0.8 per unit of Y.
For 1000 units:
0.8 x 1000 = 800.
Consumption would increase by $800.

11/3 divides by 60/11 = 660/33 = 20
Answer: 53.6
Explanation:
When given a side and its opposing angle and another angle, to find its opposing side you may use the sine rule.
sin(Angle)/opposing side = sin(Angle)/opposing side
Applying this formula will give us the following:
1) sin90/x = sin66/49
2) 1/x = 0.01864
3) 1/0.01864 = x
4) x ≈ 53.6
