Answer:
The number of integers that can't be expressed as a difference between the squares of two integers is 250.
Step-by-step explanation:
(Assuming dogs have 4 feet, birds have 2 and buyers have 2)
One possibility is 4 dogs, 2 birds and 2 buyers [16 + 4 + 4]
Hi there!
One way to find the solution is to list out all of the possible combinations- which, in most cases, will take a long time.
<u>Another more effective way</u> to find the possible combinations is to multiply the amount of each component together and find the product of all of the amounts of items combined.
In this case, you would multiply:
6 * 3 * 3 * 3 * 3
= 486.
So, there'd be 486 combinations.
Hope this helps!
That is the formula to find the volume of a sphere. It's best to just memorize it as it is hard to come up with. The (4/3) is a constant (it is always that fraction). Pi is also a constant but it is a never ending decimal number so they use the Greek number pi to represent it. Most schools use 3.14 to equal pi but some just use 3 so be sure to check with your teacher. The r here is referring to the radius of the sphere which is the measurement from the center out to the edge. To find the volume you need to multiply (4/3) times Pi times (the radius squared)
