Arctan(53/22) = 67.5 degrees
Answer:
8
Step-by-step explanation:
Since there are 3 (an odd number) ages, the median is the middle one. So, we know two of the ages are 10 and 15. In order for the mean of the three ages to be 11, their total must be 33. The total of the two known ages is 25, so the remaining one must be ...
33 -25 = 8
The youngest child is 8.
Given
part a
Convert each fraction to a decimal by dividing. Tell if it terminating or repeating.
It is terminate
Part b
It is repeating
Answer:
Width = 12
Length = 16
Step-by-step explanation:
Width = x
Length = x + 4
2x + 2(x+4) = 56
2x + 2x + 8 = 56
4x = 56 - 8
x = 48/4
x = 12
Answer:
Step-by-step explanation:
First, you can reduce it
4(n^2-11n+30)
This should make it easier to work with. But remember, keep the 4 there. You cannot just get rid of it because it would change the value of the equation
Now find factors of 30 that have a difference or ad up to 11.
Factors of 30:
1, 30
2, 15
3, 10
5, 6
Ahh yes, 5 and 6 add to 11
4(n-5)(n-6)
