Identify and solve the inequality that represents how many $20 bills, n, you can withdraw from the account without going below the minimum balance. 20n+100 =320, n+100<=320, or 100n+20=320?

the circle one

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:
