For each pair of numbers, tell: By what percent of the first number is the second number larger? By what percent of the second number is the first number smaller? 15 and 10

1st number is 50% larger than 2nd number.

The 2nd number is 33.33% smaller than 1st number.

Step-by-step explanation:

We have been given a pair of numbers (15 and 10). We are asked to find that by what percent of the first number is larger than the second number and by what percent of the second number is smaller than the first number smaller.

We will use percent change formula to solve our given problem as:

Therefore, the 1st number is 50% larger than 2nd number.

Since the percent change is negative, this means that 2nd number is 33.33% smaller than 1st number.

The percent is negative because 15 decreased to 10.

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.

step-by-step explanation:
