In american football, the playing field is 53.33 yards (yd) wide by 120 yards (yd) long. for a special game, the field staff want to paint the playing field orange. of course, they will use biodegradable paint available for purchase in 25-gallon (gal) containers. if the paint is applied in a thickness of 1.2 millimeters (mm) in a uniform layer, how many containers of paint will they need to purchase?

68 containers of paint.

Step-by-step explanation:

First, we need to make the conversion from milimeters to yards. Knowing that:

We get:

Knowing that the playing field is 53.33 yards wide by 120 yards long, and the paint will be applied in a thickness of 1.2 millimeters () , we can find the volume:

Now we must make the conversion from cubic yards to gallons. Since , we get:

To find the number of containers of paint they will need to purchase, we must divide by :

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:

m
