At a tree farm, there are 9 rows of 36 spruce trees. In each row, 14 of the spruce trees are blue spruce. How many spruce trees are not blue spruce?

198

Step-by-step explanation:

In all, there are 324 trees. There are 126 blue spruce. Which means that there are 198 trees left.

There are two way to figure this out.

A.) 9 * 36 = 324

9 * 14 = 126

324 - 126 = 198

B.) 36 - 14 = 22

9 * 22 = 198

Hope this helps

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:
