Divide (8.6 x 108) by (3.2 x 103). Express your answer in scientific notation.
1 answer:
In doing this division, we will first divide the 8.6 by the 3.2 to get 2.6875. Thankfully, that number is already in scientific notation so we don't have to worry about changing it. Now for the rest of the problem. When the bases are the same, and they are both 10's, you subtract the exponents. 
gives us 10^5. The answer then in scientific notation is

The complete question is
"A theater production group is making frames to support wall-like props. Three-foot beams form right triangles with 10-foot beams to allow them to stand, as shown in the image.
What is x, the angle at which the diagonal beam meets the 10-foot beam at the top of the frame?
16.7°, 17.5°, 72.5°,73.3°"
The value of angle x would be 16.7 degrees.
<h3>What is the right triangle?</h3>A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.
The angle of a right angle is always 90 degrees.
In order to find the value of x, a tan would be used.
This is because we have given the opposite and adjacent sides as 10 ft and 3 ft.
Tan Ф = opposite / adjacent
Tan Ф = (3/10)
= 16.7 degrees
The value of angle x would be 16.7 degrees.
