Since the interior is 720 divide it by 180 and you will get 4 so 4=n-2 where the n means number of sides. Move the 4 over to n=4+2 and you get n=6
Answer:
The rate of interest for compounded annually is 6.96 % .
Step-by-step explanation:
Given as :
The principal amount = Rs 4600
The time period = 5 years
The amount after 5 years = Rs 6440
Let The rate of interest = R %
<u>From compounded method</u>
Amount = Principal × 
or, Rs 6440 = Rs 4600 × 
Or,
= 
or, 1.4 = 
Or,
= 1 + 
or, 1.0696 = 1 + 
or,
= 1.0696 - 1
Or,
= 0.0696
∴ R = 0.0696 × 100
I.e R = 6.96
Hence The rate of interest for compounded annually is 6.96 % . Answer

I’m not very good at explaining it sorry
THis would be 62 / 0.56 = 110.71 to nearest hundredth
Percentage of pages of a book read by Katie = 32%
Total number of pages of the book read by Katie = 80
Let us assume the number of pages that the book has = x
Then
(32/100) * x = 80
32x = 80 * 100
32x = 8000
x = 8000/32
= 250
So the book has a total of 250 pages in it.
Then
The number of pages that Katie still needs to read = 250 - 80
= 170
So Katie needs to read 170 more pages in the book.
