Answer:
Given
if p:q=2/3:3 and p:r=3/4:1/2, calculate the ratio p:q:r giving your answer in its simplest form
We need to find the ratio p:q:r
Given p:q = 2/3 : 3 = 2/3 / 3 = 2/9
and p : r = 3/4 : 1/2 = 3/4 / 1/2 = 3/2
Now p/q = 2/9 and p/r = 3/2
We need to make p equal numerators so we get
p/q = 2/9 x 3/3 = 6/27 and
p/r = 2/3 x 3/2 = 6/4
Therefore p : q : r = 6 : 27 : 4
When you mention the coefient of the squared term, I assume you mean the value of a in y=a(x-h)²+k and not the value of a in y=ax²+bx+c (actually they are the same)
so
using vertex form
y=a(x-h)²+k
vertex is (h,k)
so, given vertex of (4,-3)
y=a(x-4)²-3
also, a point is when x=5, y=-6 so (5,-6) is a point
sub to find a
-6=a(5-4)²-3
-6=a(1)²-3
-6=a-3
-3=a
so the answer is C
Answer: 117
Step-by-step explanation: Angle FAB is just 360 degrees minus all the other angles except 30. If you view the green/shaded area as a circle, there are 360 degrees, and FAB is a section of it. So 360-70-71-48-54=117. I hope this helps!
Loss: 3 (spaceships) * 20 (points per spaceship)
Gain: 250 (points)
Total: -(3*20) + 250 = +190
