Answer:
scale factor of the smaller prism to the larger prism is B. 21/23
Step-by-step explanation:
Given
surface areas of two similar hexagonal prisms are 882cm² and 1,058 cm²?
scale factor is ratio of sides of two similar objects
thus scale factor for given prism will be = side of smaller prism / side of larger prism
in general rule
If shape of solid has scale factor of k
scale factor of area = k²
scale factor of volume = k³
_____________________________
Given in the problem area of two prism is given
we know area = side^2
scale factor of area = k²
k^2 = area of smaller prism / area of larger prism
Thus, correct option is B 21/23.
Answer:
Step-by-step explanation:
initial distance, d = 50 m at t = 0 s
t = 10 s , speed, v = 1 m/s
distance, d' = 1 x 10 = 10 m at t = 10 s
Now t = 10 s to t = 15 s it is at rest
speed, v' = 20 m/s , t' = 20 s
distance, d'' = 2 x 20 = 40 m at t = 15 s to 35 second
The graph is given below:
