I would give you an answer but I dont have enough information, I'm sorry for the inconvenience.
Answer:
see explanation
Step-by-step explanation:
the volume (V) of a cylinder is calculated using the formula
V = area of base × height
here the base is a circle with radius r = 2x²y
area of base = πr² = π × (2x²y)² = π × 4y² = 4y²π
V = 4y²π × 3x³
= 12y²π
Answer:
The mean of the combined group is 76.67 ≈ 77
Step-by-step explanation:
- The sum of the grades in Tom's group is 20×70 = 1400
- The sum of grades in Alice's group is 10×90=900
- The sum of gradees in the combined group is =1400+900=2300
- Then the mean grade of the combined group is
where
- 2300 is the sum of the all grades in the combined group
- 30 is the total number of people in the group
Answer:
y = -5
Step-by-step explanation:
2y - 10y + 30 = 70
-8y + 30 = 70
-8y = 70 - 30
-8y = 40
y= -5
Answer:
x = 119°, y = 73°
Step-by-step explanation:
y = 73° ( they are alternate angles )
x and 61° are same-side interior angles and are supplementary, hence
x = 180° - 61° = 119°
