Answer:
Step-by-step explanation:
If given tables in the picture show the proportional relationship,
Number of wheels (w) ∝ Number of buses (b)
w ∝ b
w = kb
Here, k = proportionality constant
k =
Number of buses (b) Number wheels (w) Wheels per bus
5 30
8 48
10 60
15 90
Here, proportionality constant is 6.
Similarly, If number of wheels (w) ∝ Number of train cars (t)
w = kt
Here, k = proportionality constant
k =
Number of train cars(t) Number of wheels(w) Wheels per train car ()
20 184
30 264
40 344
50 424
Since, ratio of w and t is not constant, relation between number of wheels and number of train cars is not proportional.
So set up an equation!
7* n/4 > 7
So trying to get the variable alone...
n/4 > (7/7) aka 1
n> 1*4
n> 4
Try it out!
7* 6/4 = 42/4 = 21/2= 10 and 1/2
It is greater than 7
Refer to the diagram below
If we draw a line that connects the center of rotation to one of the points, say point N, and take this line as the 0° position, then we need three 'turn' of 90° to get to 270°.
Coordinate of N' (-3, 4)
Coordinate of M' (-9, 5)
