You want to include photos on the cover of a program for the school play, two across the page. the cover is 6 1/2 inches wide and the left and right margins are 3/4 inch each. the space between the pictures is 1/2 inch. how wide can you make each picture if they are the same width?

2 1/4 inches

Step-by-step explanation:

First, subtract all of the margins from the width to get 4 1/2 inches. Then, divide this by two to get 2 1/4.

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:
