Answer: h= 5.08
Step-by-step explanation:
In a parallelogram , the formula to find the area of the parallelogram is given by :-
, where b is the base and h is the height of the parallelogram.
Given : A=64 h=? b= 12.6
Substitute these values in the above formula , we get
Divide both sides by 12.6 , we get
∴ The missing variable : h= 5.08
Initially Kevin had 25
Step-by-step explanation:
Given that,
James have 20 more than Kevin
J = K + 20
If Kevin loose 10 then james will have 3 time Kevin
J = 3( K - 10)
Equate both the equation,
3(K-10) = K+20
3k - 30 = k +20
3k - k = 20 + 30
2k = 50
K = 25
So initially Kevin had 25
Answer: 15 crocodriles
Step-by-step explanation:
We know that the ratio is 4:3
This means that for each 4 hippos, we have 3 cocodriles.
We know that there are 20 hippos.
How many groups of 4 hippos we have?
n = 20/4 = 5
So we have 5 groups of 4 hippos, this means that we also have 5 groups of 3 crocodiles, then we have:
3*5 = 15 crocodiles
You just put each x number into the fraction, so the first one would be 3/1 = 3 which means y = 3, the second would be 3/2 = 1.5 which means y = 1.5, etc
