A bicycle tire has a circumference of 84.78 inches. What is the diameter of the tire? (C=dπ)

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

hope to and hope that my answer is brainliest.(follow me )

i can't read the graph

step-by-step explanation:

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:

-1/4 > -1 2/3. -1/4 is greater than -1 2/3 because it is closer to 0 on the number line.
