3 friends share 6 pounds of grapes equally. Each pound has 40 grapes. How many grapes does each friend get

80 grapes

Step-by-step explanation:

6 pounds x 40 = 240

240 / 3 = 80

or you can do:

6 / 3 = 2

2 x 40 = 80

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:
