Answer:
About 11.31 cm
Step-by-step explanation:
If one of the legs of a right iscosceles triangle is 8, then the length of the other one must also be 8. Therefore, by the Pythagorean Theorem:

Hope this helps!
Answer:
b

Answer:
The probability of the student incorrectly solves the next problem is 44%.
Step-by-step explanation:
Let E be the event of solving a problem correctly.
Then E' is the event that the problem is solved incorrectly.
Now, recall the definition of probability.
probability of an event = 
So,
p(E) = 
Also,
p(E) + p(E') = 1 and
p(E') = 1 - p(E)
= 1 - 
= 
= 
= 
= 
= 44% rounded.
Hence, the probability of the student incorrectly solves the next problem is 44%.
Let us consider the number of edges = x
we know that a triangle will have 3 edges and a square will have 4 edges. Using this details we can form an equation.
3x + 4x = 8484
7x = 8484
x = 8484/7
= 1212
Then
Number of square tiles = 1212/4
= 303
So there are 303 square tiles in the box. I hope the procedure is clear enough for your understanding. You can always use this method for solving similar problems.
