Determine the volume formula for the cylinder. Plug in your given volume and radius to solve for h (height). See image above
Answer:
y = -27
Step-by-step explanation:
- Multiply the entire equation by 6

2*(y + 1) - (3y - 1 ) = 30
- Multiply (y +1) by 2 and (3y - 1) by (-1)
2y + 2 - 3y + 1 = 30
- Isolate y term by taking the constant term to RHS
2y - 3y = 30 - 2 - 1
-y = 27
y = -27
Area of parallelogram
A = bh
A = 11 x 9 = 99
area of triangle
A = 1/2bh
A = 1/2 (7)(11)
A = 38.5
area of figure
99 + 38.5 = 137.5
answer
137.5 cm^2
The probability that a student participates in both sports and music is 108/1376
<u>Explanation:</u>
Let x be the number of students participating in both sports and music
According to the question:
P(A or B) = P(A) + P(B) - P(A and B)
P(sports or music) = P(sports) + P(music) - P(sports and music)

P(sports and music) = 
Therefore, the probability that a student participates in both sports and music is 108/1376
