Given:
The scale of a map is
.
The distance between two buildings is 60 miles.
To find:
The distance between the given building on the map.
Solution:
We have,

It means, 80 miles in real life =
on the map.
1 mile in real life =
on the map.
60 mile in real life =
on the map.
=
on the map.
=
on the map.
Therefore, the buildings are
apart on the map.
It shows the Ora scale for area multiply width and length
C=2pr
r=C/(2p) and we are given C=85 so
r=85/(2p) meters
r≈13.53 meters (to nearest one-hundredth of a meter)
Answer:
B
Step-by-step explanation:
The equation of proportionality is
y = kx ← k is the constant of proportionality
Here k = 2 , then
y = 2x
This means that the y- coordinate is twice the x- coordinate
The only point where this is true is the point
(2, 4 ) → B
