Answer:
Each side of the field is <u>9 yards</u> long.
The correct answer is Ⓑ 9 yd.
Step-by-step explanation:
Given:
A square field has an area of 81 square yards.
Now, to get the length of each side of the field.
As, the square field is having an area of 81 square yards.
Now, to get the side of the square field we put formula:

Therefore, each side of the field is 9 yards long.
The correct answer is Ⓑ 9 yd.
Answer – 30
Solving for 11 + 5 + 3 x 2 + 8 x 1
Using the Order of Operations – BODMAS
Multiplication is prioritized above addition
Therefore, 11 + 5 + 3 x 2 + 8 x 1
= 11 + 5 + (3 x 2) + (8 x 1)
= 11 + 5 + 6 + 8
= 30

Answer:
43,680 ways.
Step-by-step explanation:
We have been given that an experiment involves 16 participants. From these, a group of 4 participants is to be tested under a special condition. We are asked to find the number of groups of 4 participants that can be chosen, assuming that the order in which the participants are chosen is irrelevant.
We will use permutations formula to solve our given problem.

For our given problem
and
.


Therefore, 4 participants can be chosen in 43,680 different ways.
To find the number you can set up a small equation (x being the number) and solve for x.
It can be written as 2 ( x + 4) < 12
Solve for x to find the number.
2 ( x + 4) < 12
Distribute the 2
2x+8<12
Subtract 8 on both sides
2x<4
Divide by 2 on both sides
x<2
Therefore the number is any number less than 2
