A percent is just that number over hundred, so if it was 20%, it would be 20/100. That could be termed to differentiate the quantity amounts
Answer:
That sign means raise to power e.g 5^2.
5 in 2 places which is 25.
Also meaning 5× 2= 25
Answer:
1. False 2. True
Step-by-step explanation:
For a geometric sequence,
1. The sequence is :
3, 13, 23, 33,...
It is not geometric. It is false
2. The sequence is :
5, -25, 125, -625
So, the sequence is geometric as the common ratio is same. It is true.
The area of the square is 9 in^2
The side of a square is the square root of the area.
Side of square = √9 = 3 inches.
The side of the square is the diameter of the inscribed circle.
Circumference of a circle is PI x diameter.
Circumference of inscribed circle = 3.14 x 3 = 9.42 inches
The diameter for the circumscribed circle would be the diagonal of the square which is 3√2 = ( Side length x √2) ≈ 4.2426
The circumference = 3.14 x 3√2 = 13.321
Find the ratio between the two circles:
Circumscribed / inscribed =
13.321 / 9.42 = 1.41
7/3 = 1/x
7x = 3
x = 3/7
