Step-by-step explanation:
Wooden Cars = 2 × Wooden Trains
Ratio is
2 : 1
In total there are 3 parts
228 ÷ 3 = 76 (1 part)
Wooden Cars = 2 × 76 = 152
Wooden Trains = 1 × 76 = 76
Answer:
OPTION B IS YOUR ANSWER.
You know its a quadratic when the second difference of each y value is same.
Here's what I mean.
Option B
First all x values differ by 1. So we're good on those.
Now for the y values
Which are
3, -1, -3, -3, -1
find the difference between the second and first fod each... Then do this a second time.
If it gives the same value for all the second differences... Then its quadratic.
-1-3 = -4
-3-(-1) = -3 + 1 = -2
-3-(-3) = -3 + 3 = 0
-1-(-3) = -1 + 3 = 2.
The values are -4, -2, 0, 2.
Now find the difference of these(2nd - 1st)
-2-(-4) = -2 + 4 = 2
0-(-2)= 0 + 2 = 2
2 - 0 = 2
Since all second differences gave 2 as their answer....
Option B is your Quadratic Function!!!
Hope this helps!

Answer:
Number of sundaes eaten per minute = 3 sundaes
Step-by-step explanation:
Number of sundaes eaten in 3 minutes = 9 Sundaes
So, by UNITARY METHOD:
Number of sundaes eaten in 1 minute = ![\frac{\textrm{Sundaes eaten in 9 minutes}}{\textrm{3 minutes}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctextrm%7BSundaes%20eaten%20in%209%20minutes%7D%7D%7B%5Ctextrm%7B3%20minutes%7D%7D)
=![\frac{9 }{3 } = 3](https://tex.z-dn.net/?f=%5Cfrac%7B9%20%7D%7B3%20%7D%20%3D%203)
So, number of sundaes eaten per minute = 3.
