100 minus 95 equals 5
25 equals 5%
100 divided by 5 equals 20
20 times 25 equals 500
500 minus 25 equals 475
Answer:475 students present/ 500 students total in school
        
             
        
        
        
P=2.50x+100
The slope of the function is 2.50 which represents the commission Dylan makes for each computer sale. :)
 
        
             
        
        
        
Answer:
First type of fruit drinks: 48 pints
Second type of fruit drinks: 32 pints
Step-by-step explanation:
Let's call A the amount of first type of fruit drinks. 55% pure fruit juice
Let's call B the amount of second type of fruit drinks. 80% pure fruit juice
The resulting mixture should have 65% pure fruit juice and 80 pints.
Then we know that the total amount of mixture will be:

Then the total amount of pure fruit juice in the mixture will be:


Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -0.8 and add it to the second equation:



                +

--------------------------------------



We substitute the value of A into one of the two equations and solve for B.


 
        
             
        
        
        
d(x) = { (x,y): y = sqrt(x) and y >=0 }
since sqrt function requires x to be >=0 so 
<u>x >= 0</u>
 
        
                    
             
        
        
        
This problem is solved better well when given the drawing
or the figure. It may have been given and you forgot to attach it in the
question. However, so that we can solve this now, I drew the figure on my own
(see the attached pic).
We can see from the figure that two parallel lines are
intersected by a straight line. This type of scenario creates special angles.
Angle PXY and angle RYX are called alternate interior angles since they are on
the interior opposite sides of the cut. 
By virtue of alternating interior angles, angle PXY and
angle RYX are congruent hence:
m∠RYX = m∠PXY 
m∠RYX = 64.36°
