Durning the martinez family trip, they drove from home to a ski lodge, a distance of 64 4/5 miles, and then drove an additional 18 4/5 miles to visit friends. If the family drove the same route back home, what was the distance traveled durning their trip?

.

Step-by-step explanation:

Since

Total distance traveled during the trip =

Hence, the distance traveled during their trip was .

i think the answer is b

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:
