The answer is B because
12^2+16^2=c^2
144+256=400
Square root of 400 is 20
Hello,
x= number of points for each multiple choice question correct
L= Louann's score
C= Carla's score
Louann got 14 multiple choice questions correct and 24 points for her essay, so:
Carla got 16 multiple choice questions correct and 14 points for her essay, so:
But we know that they got the same score, then:
Answer: Each multiple choice question was 5 points
Write the equation based on the problem
r stands for the price of a regular ticket, v stands for the price of a VIP ticket.
⇒ 69r + 40v = 12,601
⇒ 80r + 55v = 16,300
Solve the equation using elimination method.
I'm eliminating v, so I can find the r. We can eliminate v by changing the coefficient of first and second equation into the same number.
69r + 40v = 12,601 (multiply 11)
80r + 55v = 16,300 (multiply 8)
-----------------------------------------
759r + 440v = 138,611
640r + 440v = 130,400
------------------------------ - (substract)
119r = 8,211
r = 69
Subtitute 69 as r to one of the equation and find v
80r + 55v = 16,300
80(69) + 55v = 16,300
5,520 + 55v = 16,300
55v = 10,780
v = 196
So the price of a regular ticket is $69 and the price of a VIP ticket is $196
Find the difference
difference = 196 - 69
difference = 127
The difference is $127
Answer:
How do you write a perpendicular equation?
Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.
