We know 20% is 15
and now we find 80%
since 20% x 4 = 80%, we can multiply 15 by 4 to get 80% of 75
15 x 4 = 60
80% of 75 = 60
A good way to find the answer to these questions is to find it algebraically. Let's call the first number 'n'.
n + (n + 2) + (n + 4) = 54
3n + 6 = 54
3n = 48
n = 16
Therefore the numbers are 16, 18, 20
If set D is a subset of set E, it means that set E includes set D. D ∩ E = D The answer to your question is A. I hope that this is the answer that you were looking for and it has helped you.
Answer:
Find the area of each triangle and then add it up. As you are aware, to find the area of a triangle the equation is B times Height divided by 2. And to make it easier do the top left triangle and the top right triangle, add them together and then divide that by 2.
Step-by-step explanation:
3 time 5 equals 15 divided by 2 equals 7.5
5 times 8 equals 40 divided by 2 equals 20
7.5 plus 20 equals 27.5
27.5 times 2 equals 55
therefor your answer should be 55m
