All of them.
1. If you multiply by 2, they will be equal.
2. If you multiply by 5000 they will be equal.
3. If you divide by 3 they will be equal.
Find 75% of 150
First, let's convert 75% to decimal by dividing by 100:

Now, we will multiply 0.75 with 150 to find out answer:

Answer112.5
Remark
For every 3 units for NP will be 4 units. You can set up a proportion.
3*NP = 4*45
3*NP = 180 Divide by 3
NP = 180/3
NP = 60
Answer C
Answer:
Step-by-step explanation:
The area of the square is 3 units by 3 units. because the area of a square is side length squared.
side length = 3
side length^2 = 3 * 3 = 9
The area of a circle is much harder to reason out. You could start with the area of a square and use the diameter is 3 units. But the corners are rounded and you don't know off hand what the area of one of them is, let alone all 4. You are given a formula for circles area, but you have no real idea what the formula actually means. Does it take the corner area into account? At the beginning levels, we don't know.
Answer:
8% increase
Step-by-step explanation:
In this question, we are asked to calculate the percentage increase that a certain increment will give over a period of 10 years.
Let the increment be x
Mathematically from the question, we can obtain that ;
(1+x)^10 = (1+1.2)
(1+x)^10 = 2.2
1+ x = 2.2^1/10
1+x = 1.082
x = 1.082 - 1
x = 0.082
This means that x = 8.2% which is approximately 8%
