Answer:
10 6/8 or 10 3/4
Step-by-step explanation:
Calculate out how many times the denominator goes into the numerator. To do that, divide 86 by 8 and keep only what is to the left of the decimal point:
86 / 8 = 10.7500 = 10
Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.
86 - (8 x 10) = 6
Keep the original denominator and use the answers from Step 1 and Step 2 to get this:
10 6/8
Minimize the fraction part from Step 3 by dividing the numerator and denominator by 2, which is the greatest common factor, to get the final answer. 86/8 as a Mixed Number is:
10 3/4
It wouldn’t be any of these I don’t think, however I don’t know what the # means.
I thought it would be C = 15 + x(0.20)
Hope this helps
Answer:
Not a right triangle.
Step-by-step explanation:
If this triangle is a right triangle, then the Pythagorean theorem would work on it. According to the Pythagorean theorem, 
, so c would always be greater than a or b. In this scenario, the greatest number here is 18, so c = 18. Since a or b don't matter if given both legs, we have the following equation that may or may not be equal: 
. We know 8 squared is 64, and 11 squared is 121, and 18 squared is 324. This means that 
according to the Pythagorean theorem, and since 64 + 121 = 185, and 185 does not equal 324, the Pythagorean theorem does not work and the triangle is not a right triangle.
