Divide 5/6 in a calculator, write down the answer.

Clear your calculator and then divide 1 by 2.

now with those answers, clear your calculator and write the number you got when you divided 5/6 and then subtract what you got from 1/2.

5/6 -1/2 = 1/3
first you write out the problem then figure out the common denominator ; 12 then see how many times the old denominator goes into the new denominator ; 2 and 6 , then multiply the numerator to get 10 & 6 . subtract 10/12 by 6/12 to get 4/12 then divide. answer it 1/3

Triangle ABC has sides with lengths of 11, 18, and 8 units. Determine whether this triangle is a right triangle.

Arturiano [62]

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, $a^2+b^2=c^2$ , 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: $8^2+11^2=18^2$ . We know 8 squared is 64, and 11 squared is 121, and 18 squared is 324. This means that $64+121=324$ 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.
