52
Step-by-step explanation:
I don't really know what the other numbers are for but I'll just answer the first line.
Basically, you have to find what 10% of 130 is and multiply that number by 4.
130/10 = 13 (10% of 130)
4(13) = 52 (40% of 130)
You can verify this by typing in your calculator (130 x 0.40) and you should get 52.
You can also take 100% of 130 and substract by 60% of 130 to find 40%.
Answer:
I believe it is 32
Step-by-step explanation:
I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do.. 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32
Answer:
f(x)=x-4
Step-by-step explanation:
For these types of questions just find a way to turn x into y consistently so that every point works.
Answer:
Population management is important due to the fact that humans rely on different types of animals for food that if we populate to much that we could all run out of food because say if there are 30 humans and 5 pigs even if they both multiply there well still not be enough in the long run. Which throws the balance over nature off. So if we keep on populating we are practically killing are selves, population management is essential if you do not want the human race to die out.
