Answer:
13x+2
Step-by-step explanation:
I used the addition
The surface area for a cube is just the sum of the areas of all six sides which is:
A=6s^2, since s=8mm
A=6*64=384 mm^2
21.25% as a fraction is a pretty easy, but very complex problem to solve. The very first thing I would do is turn the percent to a decimal by simply moving the decimal two spaces to the left, or by dividing by 100. This makes it a lot easier.
21.25% = 0.2125
From here, the decimal reads: two thousand, one hundred and twenty five ten thousandths.
So as a fraction, it is 2125/10000.
Next, we’ll need to reduce this. I would start by dividing by twenty five:
85/400
Divide by five:
17/80
Therefore, your answer is 17/80.
Complimentary means they add up to 90
x is the angle we're looking for
x + 89 = 90
Subtract 81
x = 90 - 89
x = 1
A is the correct answer.
