You need to use the Pythagorean theory. a² + b² = c². So you would end up with 10²+10²=c². So, 10²=100, therefore you would end up with 200=c². In order to find the length of the hypotenuse, you need to find C. To do this, you need to undo the square and find the square root of 200 and C. So, you would get √200=√c² which would equal 14.1 inches. Then, if needed to check the answer, plug the 10,10,and 14.1 back into the a²+b²=c² and it should make the statement true.
The answer to 89+27+11 is 127
Answer:
John have to pay back $23,327.50 at the end of two years
Step-by-step explanation:
Simple Interest (I) = (PRT) ÷ 100
where P = Principal, R = Rate, T= Time
I = ($150500 × 7.75 × 2) ÷ 100
I = ($2332750) ÷ 100
I = $23,327.50
8/12 is .67, when rounded. In order to find her percentage, multiply .67 by 100 to get it. She got 66.7%, when rounded, on the test.
