Answer:
A. √10
Step-by-step explanation:
A rational number can be written as the ratio of two integers
A. √10
This cannot be simplified into the ratio of two integers, Square roots that cannot be simplified are irrational
B. -√81
- 9
-9/1 which is the ratio of two integers so it is rational
c. 5/4
This is the ratio of two integers so it is rational
d. 9.12
912/100
This is the ratio of two integers so it is rational
2 because it's 200,000 so two hundreds of people
Let the number = x
Writing the equation you have:
10x + 15 <= -17
Solve for x
Subtract 15 from both sides:
10x <= -32
Divide both sides by 10:
X <= -32/10
Simplify:
X <= -16/5 as a fraction or -3.2 as a decimal
For full circle area is π * R² [here R = radius],
for a sector of circle with angle β, area will be = (β/2) * R², β is in radian,
here let β = 22.5° = (π * 22.5/180) = π/8 radian,
now [(π/8)/2] * R² = 9π, [π/16] * R² = 9π
R² = 9 * 16 = 144,
R = √144 = 12 m
Answer:
I am not sure if this is right but the answer is
The area of a circle with circumference 18π is 254.5
