Pamela's dog finally had her puppies!! The lightest puppy in the litter weighed 9 ounces, which is 3/4 of the weight of the heaviest puppy. The equation 3/4w
= 9 can be used to find the weight (w) in ounces of the heaviest puppy. How much does the heaviest puppy weigh??

c

step-by-step explanation:

a is the correct

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:

b is the right answer
