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
The correct answer is -2 I just took the test.
Because when you divide both sides by a negative number, the inequality sign changes.
There are 65 boys, and the boy ratio is 13: so to find how they got that, divide 65 by 13 and that is 5. Since we now know it is the amount of people, divided by 5, we can take the girl ratio (15) and multiply it by 5 to get the amount of girls (which is 75). You need to find the total amount of students in the class so add the boys and girls (65+75) and get 140 total students
Answer:
A. $0.07 per square inch
Step-by-step explanation:
Chicago Pizza has a diameter of 14".
radius = diameter/2 = 7"
area = (pi)r^2 = 3.14159(7 in.)^2 = 3.14159(49 in.^2) = 153.934 in.^2
cost per sq inch = ($10.49)/(153.934 in.^2) = $0.068 per square inch
Answer: A. $0.07 per square inch
