Answer:
The volume of the silo is approximately 147,026.6 ft.³.
The most correct option is 147,026.5 ft.³
Step-by-step explanation:
The given dimensions of the silo are;
The shape of the silo = Composite figure of tower and roof
The shape of the tower = Cylindrical
The shape of the roof = Cone
The radius of the base of the silo, 'r' = 30 feet
The height of the cone roof of the silo, h₁ = 12 feet
The height of the entire silo = 60 feet
For the cone roof, we have;
The volume of a cone, V = 1/3 × Base area × Height
The volume of the cone roof, V₁ = 1/3×π·r² × h₁
∴ V₁ = 1/3 × π × (30 ft.)² × 12 ft. ≈ 11,309.7336 ft.³
For the cylindrical tower, we have;
The height of the entire silo = The height of the tower + The height of the roof
∴ The height of the tower = The height of the entire silo - The height of the roof
The height of the tower, h₂ = 60 ft. - 12 ft. = 48 ft.
The volume of a cylinder = Area of base × Height
The volume of the cylindrical tower, V₂ = π·r² × h₂
∴ V₂ = π × (30 ft.)² × 48 ft. ≈ 135,716.803 ft.³
The volume of the cylindrical tower, V₂ ≈ 135,716.803 ft.³
The volume of the (entire) silo, Vₙ = V₁ + V₂
∴ Vₙ = 11,309.7336 ft.³ + 135,716.803 ft.³ = 147,026.573 ft.³
The volume of the (entire) silo, Vₙ ≈ 147,026.6 ft.³.
Answer:
147,026.5 ft.³

Step-by-step explanation:
Devon’s tennis coach says that 72% of Devon’s serves are good serves. Devon thinks he has a higher proportion of good serves. To test this, 50 of his serves are randomly selected and 42 of them are good. To determine if these data provide convincing evidence that the proportion of Devon’s serves that are good is greater than 72%, 100 trials of a simulation are conducted. Devon’s hypotheses are: H0: p = 72% and Ha: p > 72%, where p = the true proportion of Devon’s serves that are good. Based on the results of the simulation, the estimated P-value is 0.06. Using Alpha= 0.10, what conclusion should Devon reach?
Group of answer choices
Because the P-value of 0.06 < Alpha, Devon should reject H0. There is convincing evidence that the proportion of serves that are good is greater than 72%.
Because the P-value of 0.06 < Alpha, Devon should fail to reject Ha. There is convincing evidence that the proportion of serves that are good is greater than 72%.
Because the P-value of 0.06 < Alpha, Devon should fail to reject Ha. There is not convincing evidence that the proportion of serves that are good is greater than 72%.
Because the P-value of 0.06 < Alpha, Devon should reject H0. There is not convincing evidence that the proportion of serves that are good is greater than 72%.
Answer:
Because the P-value of 0.06 < a, Devon should reject H0. There is convincing evidence that the proportion of serves that are good is greater than 72%.
Step-by-step explanation:
Right on edge 2022
The conclusion is (a) Because the P-value of 0.06 < Alpha, Devon should reject H0. There is convincing evidence that the proportion of serves that are good is greater than 72%.
How to determine the conclusion?The given parameters are:
Null hypothesis H0: p = 72% Alternate hypothesis Ha: p > 72%,p value = 0.06α = 0.10By comparison, the p-value is less than the alpha value
i.e. 0.06 <0.10
When the p-value is less than the alpha value, the null hypothesis is rejected.
Hence, the conclusion is (a)

3(x+8)2 + 8 = 83

Step 1
(x + 8)2 = 225
Step 2
X + 8 = +15
Step 3
X = 7 or x = -23 Step 4
Answer:
Step-by-step explanation:
I think you mean 3(x+8)², not 3(x+8)2. If you cannot type ², use ^ to mark the exponent: 3(x+8)^2.
3(x+8)² + 8 = 83
3(x+8)² = 75
(x+8)² = 25
x+8 = ±√25
x+8 = ±5
x = -8 ± 5 = -3, -13

What is the value of s? Uhm uh why is this so difficult.
Answer:
s = 47
Step-by-step explanation:
The measure of the exterior angle of a triangle is equal to the sum of the opposite interior angles
s+45 = s+6 + s-8
Combine like terms
s+45 = 2s-2
Subtract s from each side
s+45-s =2s-2-s
45 =s-2
Add 2 to each side
45+2 = s-2+2
47 =s

Step-by-step explanation:
13. A sales lady is paid commission at the rate of 3% on all goods she sells. During
one month, she sold 12 television at sh. 15,500 each, 8 D.V.D player at sh. 5,650
and 4 refrigerators at sh. 21,700 each. Calculate the total commission she earned
in that month.
Answer: Sh. 9540
Step-by-step explanation:
First, we have to calculate the cost of the total things sold. This'll be:
12 television at sh. 15,500 each = sh. 186000
8 D.V.D player at sh. 5,650 = sh. 45200
4 refrigerators at sh. 21,700 each = sh. 86800
Total cost = sh. 186000 + sh. 45200 + sh. 86800 = sh. 318000
Since the sales lady is paid commission at the rate of 3% on all goods she sells, the total commission that she earned
in that month will be:
= 3% × sh. 318000
= 0.03 × sh. 318000
= Sh. 9540

Answer:
a = 30°
b = 11°
Step-by-step explanation:
JK = 360 - 110 - 130 - 54 = 66°
Inscribed angles = 1/2 their arc
∠K = 1/2(130 + 54) = 92°
∠J = 1/2(110 + 130) = 120°
∠M = 1/2(66 + 110) = 88°
8b = 88°
b = 11°
∠L = 1/2(54 + 66) = 60°
2a = 60°
a = 30°

To prepare for a bake-off, Amy used 0.64 kilograms of flour each day for 3 weeks. How many grams did Amy use in those 3 weeks?
1 kg = 1,000 g
Answer: 13440 grams
Step-by-step explanation:
Since 1 kg is 1000 g, multiply 0.64 by 1000 to find how many grams are in a kilogram.
0.64x1000
=640 grams
She uses 640 grams each day.
How many grams does he use in 3 weeks?
1 week has 7 days
3 weeks has 21 days
3x7=21
