The bottom of Ignacio's desktop is 74.5cm from the floor. Ignacio sits in his adjustable chair, and the tops of his legs are 49.3 from the floor. Each clockwise rotation of the knob on the chair raises Ignacio's legs by 4.8cm. Write an Inequality to determine the number of clockwise rotations, r, Ignacio could make with the knob, without his legs touching the desk? What is the solution set of the Inequality?

total of apples - take away four

6-4 = 2

answer is 2 apples

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:
