Answer:
<h2>Graph
D</h2>
Step-by-step explanation:
When the process starts, the water is flowing slowly, since there is only 1 valve open. That represents the part on this where the line is going almost horizontally.
When the operator opens the second valve also, then there will be more water released at once, which means that the water will come out faster, and take less time. That represents the middle part of the line, which is almost vertical.
When the operator shut's down the second valve, then the process gets slower, and that represents the part which is going slow again. And that represents the 3rd part, where the line is going almost horizontal again.
Mark me brainliest if this could help! Thanks!
That would be (4/6) of 45 minutes, or 180/6 minutes, or 30 minutes.
You could also find her rate: 6 miles / 45 minutes, or 8 miles / 60 minutes.
Write an equation of ratios:
8 mi 4 mi
---------- = ------------
60 min x
Solving for x: 8x = 240; x = 30 minutes
y=2x+1
(2x) is the slope because the slope is going up the slope will be positive and the (1) is the y intercept which means where the slope crosses the vertical line
Answer:
16
Step-by-step explanation:
21.60 divided by 1.35=16
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
