the length of a leg on a 45-45-90 triangle given the hypotenuse is half the length of the hypotenuse times sqrt(2)
hypotenuse = 10
10/2 =5
so the answer should be 5sqrt(2), which I don't see as a choice

Answer:
625
Step-by-step explanation:
<u>here we are in an inverse proportion situation :</u>
<em>As the number of days increases </em>
<em>when the number of students decreases and vice versa.</em>
__________________
Say n is the original number of students.
___________________________________________
<u>After 15 days, the rest of food is enough for n students for 45 days, </u>
<u>or enough for n+500 students for 25 days.</u>
Then
45n = 25×(n + 500)
Then
45n = 25n + 25×500
Then
45n - 25n = 25×500
Then
20n = 12500
Then
n = 12500÷20
= 625
and thus , there were 625 students in the hostel.
Answer:
-1, 2, 6
Step-by-step explanation:
We have to solve the equation as follows: 1/(x-6) + (x/(x-2)) = (4/(x²-8x+12)).
Now, we have,
⇒
⇒
⇒
⇒
⇒ or,
If, (x-2)(x-6) =0, then x=2 or x=6
If, , then
and (x-6)(x+1) =0
Therefore, x=6 or -1
So the solutions for x are -1, 2 6. (Answer)
