The 2 sides of the right triangle is 25 and 24.
Any multiple of a Pythagorean triple is also considered a Pythagorean triple. Multiplying 3, 4, 5 by 2 gives 6, 8, 10, which is another triple. To see if a set of numbers makes a Pythagorean triple, plug them into the Pythagorean Theorem.
3,4,5 5,12,13 7,24,25 8,15,17 9,12,15
Final Result: 25,24
The main part of solving this problem is carefully looking at each and every word of the problem very minutely. The details required for solving the problem is already given in the question.
Let us assume the unknown number to be = x
Then the equation for getting to the unknown number can be written as
8x - 20 = x + 15
8x - x = 15 + 20
7x = 35
x = 35/7
= 5
So from the above deduction we can easily conclude that the unknown number in the question is 5.
Answer:
70 m/s
Step-by-step explanation:
speed = √( g x depth ); where g = 9.8m/s²
given depth = 500m
equation becomes:
speed = √( g x depth )
= √( 9.8 x 500 )
= √( 9.8 x 500 )
=√4900
=70 m/s
