Answer:
1.- If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.
2.- The square root of a number is that number which when multiplied by itself two times gives us that number.
Example:
Let us use the square root of 64.
√64 = x , so that (x)(x) = 64
We know that, (8)(8) = 64
∴ √64 = 8
The cube root of a number is that number which when multiplied by itself three times gives us that number.
Example:
Let us use the square root of 64
∛64 = x , so that (x)(x)(x) = 64 ,
We know that, 4 x 4 x 4 = 64
∴ ∛64 = 4
Answer:
C
Step-by-step explanation:
We need to use the distance formula, which says that for two points 
and 
, the distance between them is:
d = 
Here, the two points are (-2.5, 4.5) and (4.75, 4.5), so:
d = 
= 7 1/4
The answer is C.
Answer:
25
Step-by-step explanation:
5 boys: 4 girls = x boys: 20 girls
Multiple of 5 to get from 4 girls to 20 girls

5 boys x 5 = 25
Answer:
(3,0)
Step-by-step explanation:
y is the verical axis
4 + 4 = 8
4 - 4 = 0
the x would stay the same because its not moving horizontally
I believe the answer is A
