A snack mix recipe calls for cups of raisins and almonds in the ratio 15 to 18. Which of the following ratios of ralsins to almonds are equivalent to 15:18? Select all that apply.

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:

493 would be the correct answer
