Given that t<span>here
are 20 light bulbs in 5 packages.
The table to find the rate
that gives you the number of light bulbs in 3 packages is given as follows:
Three different ways in which the rate can be written are:
12 light bulbs to 3 packages
12 light bulbs : 3 packages
12 light bulbs / 3 packages

Answer:
The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.
Step-by-step explanation:
Volume of a sphere:
The volume of a sphere is given by the following equation:
In which r is the radius.
Implicit derivatives:
This question is solving by implicit derivatives. We derivate V and r, implicitly as function of t. So
The radius of a sphere is increasing at a rate of 4 mm/s.
This means that
How fast is the volume increasing (in mm^3/s) when the diameter is 60 mm?
This is when . So
The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.
Answer:i am not sure
Step-by-step explanation:
This question is very hard to answer
Answer:
- The height of the other book is <em>2 3/4</em> inches.
Step-by-step explanation:
<em>From the information,we get:</em>
Two stacks of books together are = 7 1/2 inches tall.
One stack is given,that is = 4 3/4 inches.
To Find:
Solution:
Let us assume that the other height of the book be x.
Then the equation will be:
- Solve for x to get the other book's height.
Convert the mixed fractions to fractions:
<em>Subtract 19/4 from both sides:</em>
<u>Hence, we can conclude that:</u>
The height of the other book is 2 3/4 inches.
If..m/n = 5
then .. m = 5n
substitute 5n for m
(5n)² - 25n²
25n² - 25n² = 0
