Answer:
yes
the sum of the squares of the width and length is equal to the square of the diagonal
Step-by-step explanation:
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
24^2 + 70^ = 576 + 4900 = 5476
square root = 74
Answer:
136
Step-by-step explanation:
Take 68 x 2 since the side lengths are equal.
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>.
I believe the answer for the first question is A. but not 100% sure, it's the only one I can figure out to be right.
The answer for the second question is C. 90% of 30 is 27.
I hope this helps.
