Answer:
a) 80
b) 56
Step-by-step explanation:
a) Calculate the volume of the the cup using volume of cylinder equation:
Where V = Volume, r=radius, and h=height. Your answer should be in cubic inches ().
You're given diameter, so use equation to find radius.
Substituting these equations will give you:
However, the given volume of the sink is 3000, meaning that you should modify your results to match this value. Do not substitute
for 3.14..., leave it as a symbolic value. Your final V of the cup should = 37.5
Divide the volume of the sink by the volume of the cup. This number will be the amount of cups needed to empty it. In equation form: # of cups.
Note the the will cancel each other out, so there's not need to factor that in.
b) Repeat the steps above with the new d (diameter) value.
Answer: y = (-2/5)x - 7
This is the same as writing
======================================================
Explanation:
Any linear equation is of the form y = mx+b, known as slope-intercept form
m = slope
b = y intercept
We'll replace m with -2/5 and replace b with -7 to get y = (-2/5)x + (-7) which simplifies to y = (-2/5)x - 7
