Answer:
The base of the triangle is decreasing at a rate of 1.4167 inch/hour.
Step-by-step explanation:
Area of a triangle:
The area of a triangle of base b and height h is given by:

In this question:
We have to derivate the equation of the area implicitly in function of time. So

The altitude of a triangle is increasing at a rate 2 inch/hour while the area of the triangle is decreasing at a rate of 0.5 square inch per hour.
This means that:

At what rate is the base of the triangle is changing when the altitude is 6 inch and the area is 24 square inch?
This is
when 
Area is 24, so the base is:



Then





The base of the triangle is decreasing at a rate of 1.4167 inch/hour.
920 +(-559) +(-100) +(-441) +(175) +(-139)
=-144
The answer is E
Answer:
Yes, it's 13r.
Step-by-step explanation:
5r+8r=13r
Linear scale factor =1/2
volume scale factor=(1/2)³=1/8
the volume of the larger figure will be:
volume=length*width*height
volume=16×15×6
volume=1440 cubic inches
thus volume of the small sink will be:
1/8×1440
=180 cubic inches
