Which of the following expressions cannot be written as an integer? -3^0
18/3
1.2 x 10^-2
49

1.2*10^-2

Step-by-step explanation:

-3^0 is 1, because anything to the power of 0 (except for 0) is always equal to 1. 1 is an integer, so this is not the answer.

18/3=6, and 6 is an integer, so this is not the answer either.

1.2*10^-2 = 1.2*0.01 = 0.012, which is not an integer, so this is the answer.

49 is an integer, so this is not the

Therefore, the answer to this problem is 1.2*10^-2

1.2 x 10^4

Step-by-step explanation:

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.
