Step-by-step explanation:
First, you need to find the difference 3201-2750=451, it has increased by 451, then divide the difference by the original number, which is 2750 because thats what she started off with (3201 would be the new number)
Increase% = Increase ÷ Original Number ×100
451÷2750×100=16.4%
Hello there, and thank you for posting your question here on brainly.
The median is the middle number in the set.
Take one number out from each side, until you get the one in the middle.
In that case, your answer is 90.
Hope this helped!! ☺♥
I found this for you. It even tells you how the answer was achieved.
Lengths of corresponding sides of similar polygons are in proportion.
That means that 2 is to 3 as 7 is to x where x is the length of the side of the other
triangle.
2/3= 7/x
2x = 21
x = 21/2 = 10 1/2
Answer: b) 10 1/2
