4.5
Step-by-step explanation:
1/2 times base times height
( Area of a triangle )
1/2(3)(3)
=4.5
This is a trick question. 7 families had a parakeet.
N(N ∩ S ∩ K) = 10
n(ξ) = 250
n(S ∪ K) = 15 - 10 = 5
n(N ∪ S) = 20 - 10 = 10
n(N ∪ K) = 30 - 10 = 20
n(S) = 50 - 10 - 5 - 10 = 25
n(K) = 55 - 20 - 5 - 10 = 20
n(N) = 100 - 10 - 20 - 10 = 60
n(N ∪ S ∪ K) = 10 + 5 + 10 + 20 + 25 + 20 + 60 = 150
Therefore, n(N ∪ S ∪ K)' = 250 - 150 = 100
Therefore, 100 million people do not read any of the three papers.
You need k by itself, so the only way to do that is to divide both sides by 5
Answer:
q =90
Step-by-step explanation:
q/18=5
Multiply each side by 18
q/18 * 18=5* 18
q =90
