Well if you add 14 and 21 you get 35. with 35 you can have 7 groups of 5 but if they have to be equal with the number of boys and girls in each group it would still be 7. two boys in each group with three girls in each group.
Answer:

Step-by-step explanation:
To find the total mass you will add the following masses together:
1/4 + 1/4 + 2/4 + 2/4 + 2/4 + 3/4 + 3/4
For every X you list the number that many times.
The sum is 14/4 or 3 2/4 or
3 1/2.
The answer is choice D.
Answer:
Option d.
Step-by-step explanation:
Total employment for sheet metal workers in 2016 is projected to be = 201,000
This is a 6.3% increase from 2006.
Let the number of workers in 2006 be n
n + (6.3% of n) = 201,000
n + ( 0.063n) = 201,000
1.063n = 201,000
n = 
n = 189,087. 4882 ≈ 189,000
the total employment in 2006 was approximately 189,000
Option d is the answer.
To find the magnitude of the resultant vector, the formula is written as:
R² = x² + y²,
where
x and y are the perpendicular vectors along x and y axes, respectively.
So, any pair of x and y must satisfy the given equation. There are a lot os possibilities. Let's say, if x = 12, then,
20² = 12² + y²
y = 16
One answer would be a horizontal x vector equal to 12 m, and a vertical y vector equal to 16 m.
