The answer is B. You have 6 letters, and 3 are vowels. so you get 1/2. That means the answer is 0.5 because 0.5 equals 1/2
Answer:
45 sweets.
Step-by-step explanation:
6:2:1
To solve how many Jim and Dan has I did 6 x n and 1 x n until the difference of the two numbers equaled 25.
6 x 5 = 30
1 x 5 = 5
30 - 5 = 25.
So, Jim as 30 candy and Dan has 1. How much does David have?
Just do the same thing but with 2 x n:
2 x 5 = 10.
Now add them together:
30 + 10 + 5 = 45.
Therefore, 45 sweets!

Make it more general, and see what happens when you try to reduce the exponent of
x in the following integral:
Now, integrate it by parts:
where
So after one iteration, the exponent of
x was decreased by one unit.
The question is:
after how many iterations will the exponent of x equals zero? After exactly
k iterations, of course.
Therefore, for
k = 7, you have to apply integration by parts
7 times, to get rid of that polynomial factor. Then, there will be one last integral left to evaluate:
But this one doesn't need to be evaluated by parts. You can directly write the result:
Shortly, for the integral
you have to apply integration by parts
7 times (not
8 times).
I hope this helps. =)

The answer will be 8.555555555555555556 (it's a repeating decimal)
200 ÷ 5 = 40
4 • 40 = 160
