70%70, percent of a number is what fraction of that number?

Hello there!

A number that is 70% of a number is 7/10 of that number in fraction form!

I hope this was helpful and have a great rest of your day!

7/10

Step-by-step explanation:

In order to solve this you just have to make the division of 70 by 100, and thenn reduce that as much as you possibly can:

So now you know that the fraction of a number that 70% of that number represents is 7/10.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

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.
