Given:
Height of right triangle = 9 mi
Hypotenuse = 17.5 mi
Base of right triangle = Distance across lake
To find:
The distance across the lake.
Solution:
Using Pythagoras theorem:
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.


Subtract 81 from both sides.


Taking square root on both sides.
⇒ base = 15
The distance across the lake 15 mi.

Ella has both dimes (d) and nickels (n) in her piggy bank. She has a total of 36 coins in all, and has 4 more dimes than nickels. Find how much money she has in her piggy bank using a two-variable, two-equation system.
3/4 as a number = 0.75
So 1.75 x d = 14
14/1.75 = d
14/1.75= 8
D = 8
