A park is in the shape of a rectangle 8 miles long and 6 miles wide. How much shorter is your walk if you walk diagonally across the park than along two sides of it?
Answers
8 + 6 = 14
Find the hypotenuse of the triangle.
a^2 + b^2 = c^2
Where 'a' and 'b' are the two legs and 'c' is the hypotenuse.
Plug in what we know:
6^2 + 8^2 = c^2
Simplify the exponents:
36 + 64 = c^2
Add:
100 = c^2
Find the square root of both sides:
c = 10
14 - 10 = 4
So walking diagonally across will be 4 miles shorter than walking around the edges.
this would be a right triangle with the legs being 8 miles and 6 miles. using the Pythagorean theorem, the hypotenuse would be 10 miles long. therefore, he would be walking a total of four miles less if he walked diagonally.

maria is buying a digital camera on layaway for $193. if she makes a down payment of $25 and pays $24 each week, how many weeks will it take maria to pay for the digital camera.
Answers
Price of the digital camera that Maria is buying from layaway = $193 Amount of money that Maria pays as down payment = $25 Amount of money that Maria pays each week = $24 Let us assume the number of weeks required by Maria to pay for the digital camera = x then 25 + 24x = 193 24x = 193 - 25 24x = 168 x = 168/24 = 7 So Maria will require 7 weeks to pay for the digital camera.
