Answer: a child ticket costs $14.50

Step-by-step explanation:

x=children ticket

x+4.50=adult ticket

3 children and 2 adult

3x+2(x+4.50)=81.50

3x+2x+9.00=81.50

5x+9.00=81.50

5x+9.00-9.00=81.50-9.00

5x=72.50

5x/5=72.50/5

x=14.50

Find the missing side of the triangle. Round your answers to the nearest tenth if necessary.
Alik [6]

Given:

In a right angle triangle, the measures of two legs are 5 ft and 5.6 ft. The measure of the hypotenuse is x.

To find:

The value of x.

Solution:

Pythagoras theorem: In a right angle triangle,

(Hypotenuse)^2=(Base)^2+(Perpendicular)^2

Using Pythagoras theorem, we get

(x)^2=(5)^2+(5.6)^2

x^2=25+31.36

x^2=56.36

Taking square root on both sides, we get

x=\sqrt{56.36}

x=7.50733

x\approx 7.5

The measure of missing side is 7.5 ft. Therefore, the correct option is D.
