T = k/R where k is the constant of variation, T=time and R=speed.
Plug in the given values:-
12 = k/60
k = 12*60 = 720
So the equation of variation is T = 720/R
At 85 mph we have
T = 720 / 85 = 8.47 hours (answer)
Answer:
41-50 ⇒ 4
Step-by-step explanation:
Numbers 42,43,45 and 48 in the range of 41-50 so there are 4 numbers in the range
Ok i found it now i can help
Answer:
B'(6, 6) ; C'(12, 6)
Step-by-step explanation:
The points are not labeled so I'm going to assume the points are as follows:
A(3, 9)
B(3, 3)
C(6, 3)
In order to dilate with a scale factor of 2, simply multiply the x and y coordinates by 2.
B(3, 3) ⇒ B'(6, 6)
C(6, 3) ⇒ C'(12, 6)
C is not equivalent to all the expressions
