#1. Joseph wants to find the side length of a square that has an area of 150
feet. Should his answer be rational or irrational? Explain your reasoning."

The answer is irrational

Step-by-step explanation:

we know that

The area of a square is given by the formula

where

b is the length side of the square

In this problem we have

substitute in the formula

take the square root both sides

simplify

Remember that

A Rational Number is a number that can be made by dividing two integers

so

The length side is not a integer

therefore

The answer is irrational

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
