Answer:
2) 4/3
Step-by-step explanation:
(4^-3 * 3^4 * 4^2)/(3^5 * 4^-2)
4^-3 * 3^4 * 4^2 = 4^-1 * 3^4
(4^-1 * 3^4)/(4^-2 * 3^5)
(3^4)/(3^5) = 1/(3^5-4)
(4^(-1))/(4^-2 * 3^(5-4)
(4^-1)/(4^-2 * 3)
4^(-1 - (-2)) / (3)
-1 - (-2) = 1
4/3
This means that every 1 inch in the drawing is 24 inches of the actual size.
Hope this helps!
Answer: A)
Step-by-step explanation: If You just look at the numbers you can single out which one is correct
Answer:
Step-by-step explanation:
since there is no given formula I'm guessing that's what we want to find?
use the dist. = rate * time formula for this kind of problem
or d = r*t ( this looks like the word "dirt" to me so I call this the dirt formula partly b/c it's dirt simple, and it's generally about moving across some give dist. of dirt :P )
so Jean's rate is 64 MPH
her total distance is 448 miles
rearrange the d = rt formula so that you are solving for the thing you don't know.. yet.... t (time) for this case
soooo...
d/r = t
plug in number
448 / 64 = t
7 = t (in hours)
18 divided by 4 this equals 4 with a remainder of 2 so i guess the 2 go in another row
