Is 5 m, 20 m, 25 m a right triangle
2 answers:
Answer:
No
Step-by-step explanation:
We can check this using the Pythagorean Theorem, .
First, we can plug our two smaller sides in for a and b, and the largest side in for c.,
Next, we can check the left side of the equation, which we find to be:
Then, we can add these products and achieve the result of 425
Finally, we can solve the right side of the equation, which equals 625
As 425 ≠ 625, this equation fails the Pythagorean Theorem, and is therefor false.

Answer:
6 L
Step-by-step explanation:
Given two solutions:
1st solution is 90% saline solution. Let the volume of this solution be litres.
2nd solution is 50% saline solution. Volume of this solution = 4 L
Resultant solution is 74% saline.
To find:
The volume of 1st solution = ?
Solution:
Total volume of the 74% saline mixture = (4+) Litres
We can write equation here, as per the percentage of saline in the mixtures.
90% of L + 50% of 4 L = 74% of (
+4)
Therefore, the volume must be <em>6 L</em>.
