Answer:
similarity
Step-by-step explanation:
look , dude
the two triangles have the following features:
the angle B= angle C = 90 degree
the angle A= the angle F 
so  the third angle in the first triangle = the third angle in the second triangle
so you have one condition of similarity which is the three angles are equal 
to get the answer for lengths :
ab/fe= constant of proportionality 
thus ab/fe=2.5/5=.5
so ac/13=.5 thus ac=6.5
and 6/de=.5 so de=12 
 
        
             
        
        
        
The price of Ravi's lunch, before tax and tip was added to the total cost of the meal is $13.19.
<h3>What is the price of the lunch?</h3>
Both the tax and the tip paid would increase the cost of the meal. Thus, their dollar value has to be subtracted from the total amount he pays.
Value of the lunch after the tip has been removed = (1 - 0.2) x 17.92 = $14.34
Value of the lunch after the tax has been removed = (1 - 0.08) x $14.34 = $13.19

Answer:
Y = 50x
Step-by-step explanation:
Remember that slope intercept form is Y = mx + b indicating that m is the slope
To solve this equation use the formula
Y2 - y1 , x2 - x1: 
50 - (- 50) = 100
25 - (-25) = 50 
100/50 = 50/1
So the answer is y = 50x

Answer:
The height is 2.25 meters. 
Step-by-step explanation:
The volume of a right rectangular prism is the product of the length, width, and height. So it would be V=w*l*h.
Because you have been given the values of the volume, width, and length, you can plug in those values into the equation to find the height. It should look like this: 43.875=5 * 3.9 * h
Then you can divide both sides of the equation by 5 * 3.9. 
So... 43.875/(5*3.9)=h
therefore h= 2.25. 
hope this explanation makes sense!
