Otto has some whipping cream that is 30% butterfat and some milk that is 2% butterfat. He wants to make a 500 mL mixture of them that is 12% butterfat. Here's a graph that shows a system of equations for this scenario where x is the volume of whipping cream he uses and y is the volume of milk he uses. A graph with two lines and a point. what does k represent?

12cm

the answer is d

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:
