The lengths of two sides of a right triangle are 12 inches and 15 inches. What is the difference between the two possible length

andrew11 [14]

we know that

In a right triangle

Applying the Pythagorean Theorem

$c^{2} =a^{2} +b^{2}$

where

a and b are the legs of the triangle

c is the hypotenuse of the triangle

Step N $1$

Assume that the third side is a leg

In this case we have

$a=12\ in\\c=15\ in\\ b=?$

$c^{2} =a^{2} +b^{2}$

Solve for b

$b^{2}=c^{2} -a^{2}$

substitute the values

$b^{2}=15^{2}-12^{2}$

$b^{2}=81$

$b=9\ in$

Step N $2$

Assume that the third side is the hypotenuse

In this case we have

$a=12\ in\\b=15\ in\\ c=?$

$c^{2} =a^{2} +b^{2}$

substitute the values

$c^{2}=12^{2}+15^{2}$

$c^{2}=369$

$c=19.2\ in$

Step N $3$

Find the difference of the third sides

$19.2\ in-9\ in=10.2\ in$

therefore

the answer is

$10.2\ in$

At high school basketball game, the athletic department sold 250 tickets and brought in 837.50. Adult tickets cost $5 and studen

Tpy6a [65]

Answer:

The system of equations is:

$a+s = 250\\5a+2.50s = 837.50$

Here a is the number of adult tickets and s is the number of student tickets

Step-by-step explanation:

We will use the given statements to make a system of equations for the given scenario.

First of all we have to decide which variables to be used.

Let a be the number of adult tickets and

Let s be the number of student tickets

So according to the statement that the department sold 250 tickets in total, the equation will be:

$a+s = 250$

This is equation one of the system of equations

According to the statement that cost of adult ticket is $5, total cost of adult tickets will be: $5a$

According to the statement that cost of student ticket is $2.50, total cost of student tickets will be: $2.50s$

The total earning was $837.50 so the second equation will be:

$5a+2.50s = 837.50$

Hence,

The system of equations is:

$a+s = 250\\5a+2.50s = 837.50$

Here a is the number of adult tickets and s is the number of student tickets
