Answer:
The simplest form of the given expression (2y/y + 2) + (4/y + 2) is
6 + 4y
Step-by-step explanation:
It is given an expression in variable y
(2y/y + 2) + (4/y + 2)
<u>To find the simplest form</u>
(2y/y + 2) + (4/y + 2) = 2y/y + 2 + 4y + 2
= 2 + 2 + 4y + 2
= 6 + 4y
Therefore the simplest form of the given expression is 6 + 4y
Answer:
80 Students were surveyed.
Step-by-step explanation:
To find the answer we need to do a Rule of Three. The Rule of Three is a Mathematical Rule that will help us to solve problems based on proportions.
1. I know that a 65% of students are 52 students. I need to know how many students represent that 100%.
2. So if 52 students mean _____ 65%
X students mean _____ 100%
Pay attention here. We have to put the same elements in the same columns. Students with studients and percentage with percentage.
3. Now I have to cross these details. I have to multiple 52*100. So:
52*100= 5200
4. Then divide that result by 65.
5200/65= 80
5. So 80 is the total number of students surveyed.
Answer:
64π
Step-by-step explanation:
Since the diameter of the circle is 16, the radius is half of that which is 8.
Area = πr² = 64π
