Answer:
n = 30
Step-by-step explanation:
Let n represent the number. Then (2/3)n = 20.
Solve for n by multiplying both sides by (3/2): n = (3/2)(20) = 30
- 17/12 should be the answer.
Lines f and g are parallel and the two angles are same-side angles, so they add up to 180 degrees. An equation for this would add up to 180, then solve for x to find the answer to the problem.
5x + (9x + 26) = 180, combine the like terms.
14x + 26 = 180, subtract 26 from both sides.
14x = 154, divide both sides by 14.
x = 11; so your answer is B. 11.
Answer:
20π square units
Step-by-step explanation:
The sector area is found using the proportion ...
sector area / circle area = sector angle / whole circle angle
Multiplying by "circle area", we get ...
sector area = (circle area)( sector angle / whole circle angle)
= (100π)(2/5π)/(2π)
= (100π)(1/5)
sector area = 20π
Domain. The domain of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The domain is the set of all possible x-values which will make the function "work", and will output real y-values.
