Asheet of paper is 8 1/2 inches wide and 11 inches long. the sheet is printed with a margin 1 1/4 inches wide on all four sides. find the perimeter of the printed part of the page

Step-by-step explanation:

Given:

Dimensions of the paper:

Length, l = 11 in

Width, b = 8 × 1/2 in

= 17/2 in

Printed paper dimensions:

Length, lp = length, l - margin

= 11 - 1 × 1/4

= 39/4 in

Width, bp = width, w - margin

= 17/2 - 1 × 1/4

= 29/4 in

Perimeter of a rectangle, P = 2 × (lp × bp)

= 2 × (39/4 + 29/4)

= 68/2 in

= 34 in

answer: im gonna go with milli

step-by-step explanation:

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:
