Morgan is working two summer jobs, washing cars and walking dogs. she must work
no less than 14 hours altogether between both jobs in a given week. write an inequality that would represent the possible values for the number of hours washing cars, w, and the number of hours walking dogs, d, that morgan can work in a given week.

Step-by-step explanation:

w = washing cars, d = walking dogs

w + d > = 14 (thats greater then or equal to)

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
