Answer:
6 times
Step-by-step explanation:
The chance of spinning it once is 1/5 because 2/10 of the spaces are red and simplify it to 1/5. So it is simple from here, you just multiply how many times your are spinning it (which is 30) by 1/5 cause that's the chance of it landing on red.
Answer:
Step-by-step explanation:
Let x is the total population of the world.
Therefore, by the condition given the population of North America is 
Again it is given that 
fraction of the world's population lives in the United States of America.
So, 
is the population of USA.
Therefore, the fraction of the population of North America that is the population of USA will be 
(Answer)
The answer in fraction form is 1/27
x = 1/27
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°
