Answer:
A = 20.25π sq meters
Step-by-step explanation:
C = 2πr
9π = 2πr
divide π from each side to get:
9 = 2r
r = 9/2 or 4 1/2
A = πr²
A = π (4.5²)
A = 20.25π
Answer: I am pretty sure the answer is 7.
Step-by-step explanation:
15≥2p+1
subtract 1 from each side to get
14≥2p
divide 2 by each side to get
7≥p
I hope this helped
Answer:
The value of g in the relative frequency table is 33%.
Step-by-step explanation:
We are given the following information; A 4-column table with 3 rows. The first column has no label with entries likes A, B, total. The second column is labeled C with entries 20%, 32%, 51%. The third column is labeled D with entries g, 16%, 49%. The fourth column is labeled total with entries 53%, 47%, 100%.
Representing the above information in tabular form, we get;
C D Total
A 20% g 53%
B 31% 16% 47%
Total 51% 49% 100%
Now, after seeing the whole table, it is clear that value of g is given by;
20% + g = 53%
g = 53% - 20%
g = 33%
Hence, the value of g in the relative frequency table is 33%.
C - is a hypotenuse,
so we can use Pythagorean theorem.
c² =a² +b²
c² = 8²+12²=64 + 144 = 16*4 +16*9=16(4+9) =16*13
c²=16*13
c=√(16*13)=√16*√13=4√13
c=4√13
Answer C. 4√13
