Answer:
a2 = 11
Step-by-step explanation:
15 + 45
GCF = 15
15/15 = 1
45/15 = 3
(15 * 1) + (15 * 3) =
15(1 + 3) <===
Answer:
15 boys.
Step-by-step explanation:
A class constituting of boys and girls:
Has a total of 35 students.
The number of girls outnumber that of boys by 5.
Let the number of boys be x such that the number of girls is x + 5.
∴
x + x + 5 = 35
2x + 5 = 35
2x = 35 - 5 = 30
x = 30/2 = 15
So there are 15 boys and 35 - 15 = 20 girls.
*<em>I believe you can now solve the second question.</em>
Answer:
512 ways
Step-by-step explanation:
Given
Selection
Faculty Member = 1
Male Student = 1
Female Student = 1
Parent = 1
School Board Member = 1
Select from:
Faculty Member = 2
Male Student = 4
Female Student = 4
Parent = 4
School Board Member = 4
Required
Determine how many ways they can be selected
There are 2 faculty members of which 1 will be selected from.
Any of these two members may be selected.
So, Selection = 2
There are 4 male students of which 1 will be selected from.
Any of these four students may be selected.
So, Selection = 4
There are 4 female students of which 1 will be selected from.
Any of these four students may be selected.
So, Selection = 4
There are 4 parents of which 1 will be selected from.
Any of these four parents may be selected.
So, Selection = 4
There are 4 school board members of which 1 will be selected from.
Any of these four members may be selected.
So, Selection = 4
Total number of selection is then calculated as thus:
<em>Hence, there are 512 ways</em>
