A silo is a composite of a cylindrical tower with a cone for a roof. What is the volume of the silo if the radius of the base is 30 feet, the height of the roof is 12 feet, and the height of the entire silo is 60 feet?
147,026.5 ft
135,716.8 ft
180,955.7 ft
169,646.0 ft
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

Answer:
x=5 y=-6
Step-by-step explanation:
3x+y=9 ------eqn1
y=4-2x -------eqn2
using substitution
put y=4-2x into eqn1
3x+4-2x=9
x=5
put x=5 into eqn2
y=4-2(5)
y=4-10
y=-6
From a distance of 1217 feet from a spotlight,the angle of elevation to a cloud base is 43 degrees. Find the height of the cloud base to the cloud base to the nearest foot
Answer:
1134.9 ft
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE FIQURE
From, trigonometry,
Tan(X) = opposite/ adjacent
Distance from the spotlight = 1217 ft, which is the adjacent sides
Let the height of the cloud= X
, Which is the opposite sides
Then substitute, we have
Tan(43°)= X/1217
(0.9325)= X/1217
X= 0.9325×1217
= 1134.9 ft
Hence, the height of the cloud base to the cloud base to the nearest foot is 1134.9 ft
A water spout is filling a large container with water. After 5 hours the container held 24L of water. After 8 hours the container held 30L of water. At this rate, how much water was in the container at 2 hours?
Answer:
Step-by-step explanation:
This is a direct proportionality. If a water spout is filling a large container with water, hence the time taken to fill the container is directly proportional to the volume v of water. MAthematically;
t = kV
If after 5 hours the container held 24L of water, then;
5 = 24k
k = 5/24
Also if after 8 hours the container held 30L of water
8 = 30k
k = 8/30
To get the rate of the container at 2 hrs

Answer:
5[tex]\frac{7}{8}[/tex]
Step-by-step explanation:
You subtract all those distances from 22 to calculate the remaining distance.
22-4[tex]\frac{3}{4}[/tex]= 17[tex]\frac{1}{4}[/tex]
17[tex]\frac{1}{4}[/tex]-5[tex]\frac{1}{8}[/tex]=12[tex]\frac{1}{8}[/tex]
12[tex]\frac{1}{8}[/tex]-0=12[tex]\frac{1}{8}[/tex]
12[tex]\frac{1}{8}[/tex]-6[tex]\frac{1}{4}[/tex]=5[tex]\frac{7}{8}[/tex]
So the answer is 5[tex]\frac{7}{8}[/tex]

Triangle DEF is translated five units up. If point D has coordinates (-3, -5) what are the coordinates of D'?
A.
(-3, 0)
B.
(2, -5)
C.
(-3, -10)
D.
(2, -10)
Answer:
A
Step-by-step explanation:
A translation of 5 units up means adding 5 to the y- coordinate
Then
D (- 3, - 5 ) → D' (- 3, - 5 + 5 ) → D' (- 3, 0 ) → A

7. After a discount of 30%, you pay $49.00 for a video game. What was the original price of the game?
Answer:
$70.00
Step-by-step explanation:
Percentage of original price paid
= 100% -30%
= 70%
70% of original price ----- $49.00
1% of original price ----- $49.00 ÷70= $0.70
100% of original price ----- $0.70 ×100= $70.00

Miranda sold movie DVD’s for $12 and television DVD’s for $9 and has collected $1167 from the sales of both. The number of movies sold is 4 less than 3 times the number of television shows. How many movie DVD’s were sold, and how many television DVD’s were sold?
Answer:
number of be television be 27 and the number of movies would be 50
Step-by-step explanation:
The computation of the number of DVD sold and the number of television sold is shown below:
Let us assume the number of television be x
So, the number of movies would be (3x - 4)
Now according to the question the following equation is made
12(3x - 4) + 9x = $1167
36x - 48 + 9x = $1,167
45x = $1,215
x = 27
So, the number of be television be 27
And, the number of movies would be
= (3x - 4)
= 3(27) - 4
= 50

Heather puts together 25 of a puzzle on Saturday and 310 on Sunday. Nicole has the same puzzle, and she puts together 45 of her puzzle. How much more of the puzzle does Nicole put together than Heather? A. 110 B. 310 C. 15 D. 45
Answer:
1/10
Step-by-step explanation:
Here is the correct answer
Heather puts together 2/5 of a puzzle on Saturday and 3/10 on Sunday. Nicole has the same puzzle, and she puts together 4/5 of her puzzle.How much more of the puzzle does Nicole put together than Heather? A. 1/10 b. 3/10 c. 1/5 d 4/5
total puzzle heather put together =
[tex]\frac{2}{5} + \frac{3}{10}[/tex]
[tex]\frac{4 + 3}{10}[/tex] = 7/10
the next step is to subtract 7/10 from the fraction Nicole put together
[tex]\frac{4}{5} - \frac{7}{10}[/tex]
[tex]\frac{8-7}{10}[/tex] = 1/10
