Answer:
<em>D. 69 Km</em>
Step-by-step explanation:
<u>Scaling</u>
Maps usually represent real areas on the field, but since they cannot fit in pieces of paper, we use scales where sizes and distances are all proportional to the real measurements.
On the map of the question, we know 1 cm represents 30 Km. It means that we can know approximate real distances by measuring the distances on the paper or blueprints.
Two cities are 2.3 cm apart on the map, it means that they are really 2.3*30 =69 Km apart
It’s the first one clearly because of y=kx or mostly because you multiply it
Answer:
D
Step-by-step explanation:
Because the closed dot is connected to the one less than 1, we know that one of the equation is less than or equal to 1. So this eliminates A.
B makes no sense because it shows two equations for when x < 1. So this one can be ruled out immediately.
We also notice the shape of the functions, the one on the bottom looks like a cube, you can make out the beginning of the chair shape. So the one that is less than or equal to 1 is the cubic function. Which eliminates C.
This leaves D and you can plug in values of x and y to confirm this is correct.
Volume Equation: V=4/3(pi)r^3
Surface Area: A=4(pi)r^2
She can add 35 and 9 which equals 44
