24 - 6 is 18
Answer:
B. 255 m
Step-by-step explanation:
<u>use similar triangle</u>
L / 60 = 85 / 20
L = (85 * 60) / 20
L = 255 m
A triangle with an angle >90 is an obtuse triangle the other two remaining angles would be acute <90
total degrees must = 180
Answer:
- Cost is Increasing at a rate of 20,000 per week
- Revenue is decreasing at a rate of 100,000 per week
- Profit is decreasing at a rate of 120,000 per week
Step-by-step explanation:
The cost, revenue, and profit equations for a company manufacturing calculators are given below:
- Cost, C=90000+40x
- Revenue,

- Profit = R - C
When Production output x=4000
<u />
<u>Change in Cost</u>
Cost, C=90000+40x

<u>Change in Revenue</u>

<u>Change in Profit</u>

Therefore, when production output is 4000 and increasing at a rate of 500 calculators per week,
- Cost is Increasing at a rate of 20,000 per week
- Revenue is decreasing at a rate of 100,000 per week
- Profit is decreasing at a rate of 120,000 per week
