Using the triangle diagram below in the rules for special right triangles, discover the four missing links and choose them from

Nady [450]

Answer:

The solution for the system of right triangles are, respectively: $a = 2\sqrt{6}$ , $b = 4\sqrt{3}$ , $c = 4\sqrt{6}$ , $d = 6\sqrt{2}$

Step-by-step explanation:

By Geometry, we get the following equivalencies:

$a = 2\sqrt{6}$ (45 - 45 - 90 Theorem)

$b = \sqrt{2}\cdot (2\sqrt{6})$ (45 - 45 - 90 Theorem)

$b = 4\sqrt{3}$

$c = \frac{2\sqrt{6}}{\frac{1}{2} }$ (30 - 60 - 90 Theorem)

$c = 4\sqrt{6}$

$d = \frac{2\sqrt{6}}{\frac{\sqrt{3}}{3} }$ (30 - 60 - 90 Theorem)

$d = 6\sqrt{2}$

I rent a gym for $150.00 for 30 students. Another time I rent the gym for

Mamont248 [21]

Answer:

$60.

Step-by-step explanation:

Let x be the number of students and y be the total cost of renting the gym.

We are told that we rent a gym for $150.00 for 30 students. Another time we rent the gym for $270.00 for 70 students.

To find the fixed rate let us write the equation of line representing the total cost of renting gym for x students.

We will write equation of the line representing total cost in slope-intercept form of equation.

$y=mx+b$ , where,

m = Slope of the line,

b = y-intercept or initial value.

Let us find slope of our line using slope formula.

$m=\frac{y_2-y_1}{x_2-x_1}$

Upon substituting coordinates of our points (30,150) and (70,270) in slope formula we will get,

$m=\frac{270-150}{70-30}$

$m=\frac{120}{40}$

$m=3$

Therefore, the slope of our line is 3, which represents cost of using gym per student.

Let us substitute m=3 and coordinates of point (30,150) in slope-intercept form of equation.

$150=3*30+b$

$150=90+b$

$150-90=90-90+b$

$60=b$

So the equation $y=3x+60$ represents the total cost of renting gym for x students.

As total cost of renting gym includes charges per student plus fixed rate. The cost of using gym per student is $3.

Since, y-intercept represents the initial value. Therefore, the fixed rate for the gym is $60.
