Answer:

1.8 miles

Step-by-step explanation:

For this case we can model the problem as a rectangle triangle.

 We know:

 Length of the sides of the triangle

 We want to know:

 Length of the hypotenuse

 Using the Pythagorean theorem we have:

 d=\sqrt{3^{2} +3^{2} }\\d = \sqrt{2(3^2)} \\d = 3\sqrt{2} \\d = 4.2 miles

 Then, the distance that he would have saved if he travels directly is:

 3 + 3 - 4.2 = 1.8 miles

 Answer:

 he would have saved:

 1.8 miles

Am I correct? If not what did I do wrong
LUCKY_DIMON [66]

    You are not correct. Here's an explanation as to why: First of all, the triangle is isosceles, since it has two congruent sides that leads to the conclusion of two congruent angles, one opposite each side. This means that all three angle measurements of the triangle are x degrees, x degrees, and 40 degrees. To solve for x, add all three values together and set them equal to 180 degrees, the sum of three angles in any triangle. Your mistake is adding only one x to 40, which isn't inclusive of all three triangles. I hope this helped!

The Moores family paid $6 more for skate rentals than the Cotters did. Together the two families paid $30 for skate rentals. How
Mademuasel [1]
<span>Moores Family Paid = 6 dollars mores for skate rental than the cotters did.
30 dollars = the total amount they paid for skate rentals.
Let Family Moore have the variable X
Let the Family Cotters have the variable Y
=> x = y + 6
=> y = 30 – 6 / 2
First, let’s solve the Y
=> Y – 30 – 6 / 2
=> Y = 24 / 2
=> y = 12
Now, let’s solve for X
=> X = y + 6
=> x = 12 + 6
=> X = 18
