Step-by-step explanation:
when 2 shapes are similar, it means that all their angles are the same compared with each other.
and all distances (incl. side lengths) if one shape correlate to the corresponding distances in the other shadow by the same ratio or factor.
we have one side (30 m in A and 50 m in B), where we have both measures.
we see that the ratio to "go" from A to B is 30/50 = 3/5.
that means a distance in A is the same distance in B multiplied by 3/5.
and that factor is the same also for every other side.
therefore,
x = 15 m × 3/5 = 3 m × 3 = 9 m
y × 3/5 = 18 m
3y = 90 m
y = 30 m
A=(3.14)r^2
A=(3.14)3^2
A=(3.14)9
A=28.26ft^2
Hope it helps and is correct :)
Answer:
y=-5
Step-by-step explanation:
-3y=15
-3y/-3=15/-3
y=-5

Step-by-step explanation:
The question is incomplete, as the required data are not given.
I will use the following data as an illustration of how to calculate median and range.
We have:
<u>Calculate range</u>
Identify the highest and the least
So, the range is:
<u>Calculate the median</u>
The number of data we are using is 6 (i.e. even).
So, the position of the median item is:
A decimal result implies that the median is the mean of the integer values before and after the result.
In this case, the median is the mean of the item at 3rd and 4th positions.
So:
