Two sides of a right triangle have the lengths 4 and 5. What is the product of the possible lengths of the third side? Express the product as a decimal rounded to the nearest tenth.

Answers

Answer 1

Answer:

Answer:

19.2

Step-by-step explanation:

1st Case:

4 and 5 are legs of the right triangle.

Using the pythagorean therom: a^2+b^2=c^2

We can say that 4^2+5^2=x^2

16+25=x^2

41=x^2

x=√41

√41 is about 6.4

x=6.4

2nd Case

5 is the hypotenuse of the right triangle and 4 is the legs.

Using the pythagorean therom: a^2+b^2=c^2

We can say that 4^2+x^2=5^2

16+x^2=25

x^2=9

x=3

Final Step

We need to multiply the two possible lengths for x. So for case 1 the length of x was 6.4 and for case two the length was 3. 6.4*3=19.2

Reserved seats for the football game cost $4.00 each and general admission tickets for $3.00 each. After the game was over, it was found that 1787 total tickets were sold and $5792 was made. Find the number each sold . SHow your work

Answers

There were 431 reserve seat tickets and 1356 general admission tickets sold.

What is Cost Function?

A cost function is a mathematical formula used to used to chart how production expenses will change at different output levels. In other words, it estimates the total cost of production given a specific quantity produced.

Let 'x' represent the number of reserve seats that were sold,

then '1787-x' represents the number of general admission tickets sold

we then have the following cost equation:

5792 = 4x + 3(1787-x)

solving for 'x' we have:

x = 431

1787-431 = 1356

Thus, there were 431 reserve seat tickets and 1356 general admission tickets sold.

Equation for tickets sold: Equation for money made:
x+y=1787 4x+3y=5792
Solve for x using substitution:
x=1787-y
Plug it into the other equation to find the value of y:
4(1787-y)+3y=5792
7148-4y+3y=5792
-y=-1356
y=1356
Now plug y back into any equation:
x+1356=1787
x=431

1356 general admission tickets were sold, and 431 reserved seats were sold.
