Mariam measured the distance for 8 wavelengths of visible light as 5,600 nanometers. what is the distance for 1 wavelength

700 nanometers

Step-by-step explanation:

8 wavelengths had a combined length of 5,600 nanometers.

We want to find the wavelength (in nm) of 1 of those wavelengths.

We will assume all of them are same wavelength. So, we can basically divide the total of 8 wavelengths by 8 to get 1 wavelength. Thus:

5600/8 = 700

Hence,

1 wavelength distance is 700 nanometers (or 700 nm)

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.
