Mr. Smith's class has collected 72 cans in a food drive. They plan to sort the cans into bags, with an equal number of cans in each bag. Write an expression to show how many cans there will be in each bag.

C

Step-by-step explanation:

They are dividing the number of cans in to x bags equally.

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:

okay..i will pick 8!
