Step-by-step explanation:

Get the square root of 316 which is 17.8

To get surface area you do cross section area x6

17.8×17.8×6=1896

To get volume you do length ×height ×width

17.8×17.8×17.8=5639.752cm³ or 5640cm³ if rounded off

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

Based on the inequality above, explain why the 'greater than' sign ( > ) changes to a 'less than' ( < ) sign.

if there are 65 boys in a classroom and the ratio of boys to girls is 13:15, how many students are in the class?
V125BC [204]
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

Chicago Pizza charges $10.49 for a medium 14" pepperoni pizza and NY Pizza charges $20.99 for an x-large 18" pepperoni pizza.
olganol [36]

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
