The perimeter of a wheat field is 640 yards. The length of the field is 3 times the width. The system 2l + 2w =640 and l =3w represents this situation, where, is the length of the field in yards and was the width in yards. Graph the system to determine the solution. What does this solution represent?

step-by-step explanation:

well what did you do it matters what you did : )

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:

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.
