In these problems, it is always a good idea to find the total population. In this case, it would be the total number of people who went on the field trip.
28+18+4=50
There are 50 people total.
To find each fraction, just put the number of students/parents/teachers over 50 and simplify.
Students
28/50=14/25
Parents
18/50=9/25
Teachers
4/50=2/25
Hope this helps!
Answer:
StartFraction 16 over 81 EndFraction
Step-by-step explanation:
There are 4 prime numbers from 2 to 10 (2, 3, 5, 7) and 9 numbers from 2 - 10. Total possibilities: 9 * 9 = 81
Prime possibilities: 4 * 4 = 16
Therefore the answer is 16/81 or StartFraction 16 over 81 EndFraction
The area of the parallelogram is 36 inches square.
We have a parallelogram shaped window whose dimensions are as follows-
base (b) : 12 inches
height (h) : 
= 6 inches
Other side = 10 inches
We have to find the area of the window.
<h3>What is the formula to calculate the area of a parallelogram of given base (b) and height (h).</h3>
The area of the parallelogram is given by -
In the question given - We can apply the above formula to estimate the area of the window.
A = 
= 36 inches square.
Hence, the area of the parallelogram is 36 inches square.
