Answer:
<h2>The volume will be 549
in
hours.</h2>
Step-by-step explanation:
A mound of sand at a rock-crushing plant is growing over time means the volume will increase with passing time.
The relation between the time and the volume is given by , where t, time is in hours and v, volume is in .
We need to find the time, when the volume v will be = 549 .
Hence,
.
The average rate of changeis given by:
m = (y2-y1) / (x2-x1)
m = (0.50-0.15) / (2002-2009)
Rewriting:
m = (0.35) / (- 7)
m = -0.05 $ / year
Answer:
the average rate of change in the cost is:
m = -0.05 $ / year
It means that the cost per print decreases 0.05 $ per year

Answer:
Degrees
Step-by-step explanation:
3x+15°+8x+7°+3x-16°
bringing the like terms together . Like terms are those terms which contains the same variable. Hence here we have 3x , 8x and 3x our like terms and the constant terms are also like terms
3x+8x+3x+15°+7°-16°
adding the similar terms and simplifying the constant terms
14x=22°-16°
14x=6°
Dividing both the sides by 14
