There are 198 boys in the introductory Chinese course
<h3>How to determine the number of boys?</h3>
The given parameters are
Total = 363
Ratio = Boys : Girls = 6 : 5
So, we have
Boys =6/(5 + 6) * total number of students
This gives
Boys = 6/11 * 363
Evaluate
Boys = 198
Hence, there are 198 boys in the introductory Chinese course

Answer:
D. 9:1
Step-by-step explanation:
The formula for the volume of a cylinder is πr² · h (pi · radius² · height) (use 3.14 for pi).
The two right circular cylinders have the same height. The larger cylinder has a radius that is three times the size of the smaller radius.
4 · 3 = 12
However, in the equation for volume, the radius is squared. Because of this, the larger cylinder is 9 times the size of the smaller cylinder because 3² = 9.
You can check your work by finding the volume of the two cylinders using the volume formula πr² · h:
3.14 · 4² · 5 = 251.2
3.14 · 12² · 5 = 2,260.8
The cylinder with a radius of 12 cm is 9 times the size of the cylinder with a radius of 4 cm.
2.260.8 ÷ 9 = 251.2
I believe the answer is 21
Answer:
The mean change of the stock price of those 5 days is $1.34.
Step-by-step explanation:
First let's list the differences then find the mean.
1.20, 2.30, 1.00, 1.80, 0.40
Now we add up all of the numbers and divide by how many numbers there are.
Mean = 1.34
The mean change of the stock price of those 5 days is $1.34.
Answer:
n = 59
Step-by-step explanation:
There's definitely a better way, i just did math randomly but here goes:
First i squared both sides. which gets you:
Cleaning this up gives you:
Now move everything to the other side so we can square this equation again
Divide both sides by -2
square again
subtract n^2 from both sides, add 6n, and add 50
Put this back into the equation and you get a correct answer!
sqrt(59 + 5) = sqrt(64) = 8
sqrt(59-10) = sqrt(49) = 7
8 - 7 = 1
