8v + 8b = 240
4v + b = 54....multiply by -2
-------------------
8v + 8b = 240
-8v - 2b = - 108 (result of multiplying by -2)
------------------add
6b = 132
b = 132/6
b = 22 <== buses hold 22 students
4v + b = 54
4v + 22 = 54
4v = 54 - 22
4v = 32
v = 32/4
v = 8 <== vans hold 8 students
Answer:
Step-by-step explanation:
If an angle measures x degrees, the measure of its supplement is (180-x) degrees.
This means that x-62.4 = 180-x, meaning that x=121.2.
So, the angles are 121.2 and 58.8 degrees.
Answer:
467 is the correct answer.
(This is not rounded, and should be one of your options as the answer.)
From that equation we know the center is: (1,-1) and the radius is three. Since the distance from the center to (0,0) is:
d^2=1^2+1^2
d^2=2
d=√2
Since d<r, √2<3, the circle intersects the y-axis two times.
So the statement saying that the circle intersects the y-axis is true.
Well if i had to make an educated guess my assumption would be similar to the hypothesis of this complicated situation now what i'm trying to say is i have no idea hope you find someone who can help you.
