Answer:
48 yellow triangles
Step-by-step explanation:
this problem can be represented as a ratio
4b : 12y (4 blue to 12 yellow)
16 blue triangles is 4 more time the amount than the original ratio.
16b : ?y
you can solve this problem by multiplying 12 by 4
12 * 4 = 48
this now means that for the 16 blue triangles, there should be 48 yellow.
16b : 48y
i hope this makes sense to you, and i was helpful.
stay safe!!

Answer:
y-y1 = m (x-x1)
where
m is the slope
and (x1,y1) is one of the points given.
You have been given 2 points (-12,8) and (9,1). You can call one of them (x1,y1) and the other (x2,y2). It doesn't matter which one is which.
But before we go further, we need to determine the slope.
We can do this from the points as well.
y2-y1
m = ---------
x2-x1
Let's say
(x1,y1) = (-12,8)
(x2,y2) = (9,1)
This gives us a slope of
y2-y1 1-8 -7 -1
m = --------- = ---------- = ---- = ---
x2-x1 9-(-12) 21 3
Now that we have everything we need
y-8 = (-1/3)[x-(-12)]
Distribute the -1/3
y-8 = (-1/3)x -4
If we add 8 to both sides we have the equation in the slope intercept form (y=mx+b)
y = (-1/3)x + 4
Answer:
99.0 in²
Step-by-step explanation:
The area (A) of the sector of the circle is calculated as
A = area of circle × fraction of circle
= πr² × 
( where r is the radius )
Here r = 9, thus
A = π × 9² × 
= 81π × ≈ 99.0 in²
