What is the percent increase from 250 to 900? 1. write the percent change formula for an increase. percent increase = amount of increase original amount 2. substitute the known quantities for the amount of the increase and the original amount. percent increase = 900 − 250 250 3. subtract. percent increase = 650 250 4. express the ratio as a percent: %           

260 %

Step-by-step explanation:

1) Since, the percentage formula is,

2) Given,

Original amount = 250,

New amount = 900

So, the amount of increase = New amount - Original amount = 900 - 250 = 650

By substituting the values,

3) Now, for expressing the ratio into percentage we need to multiply by 100,

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
