Answer:

5127079.21 cubic feet

Step-by-step explanation:

The silo is in the shape of a cylinder and a cone.

The volume of the silo will be the sum of the volumes of the cylinder and the cone.

Therefore, its volume is:

[tex]V = \pi r^2h + \frac{1}{3} \pi rH[/tex]

where r = radius of cylinder and cone

h = height of cylinder

H = height of cone

The radius of the base is 120 feet, the height of the roof (cone) is 25 feet. The height of the entire silo is 130 feet. This means that the height of the cylinder is:

130 - 25 = 105 feet

Therefore, the volume of the silo is:

[tex]V = (\pi * 120^2 * 105) + (\frac{1}{3} * 120^2 * 25)\\\\V = 4750088.09 + 376991.12\\\\V = 5127079.21 ft^3[/tex]

The volume of the silo is 5127079.21 cubic feet.

Answer:

the answer is b. (since you accidentally typed 759 not 750)

Step-by-step explanation:

The formula for simple interest is

A = P (1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

and the interest is going to be 750 after you plug it in, they are not asking for the amount of money total, but the amount of interest earned.

3 percent simple interest for 5 years means you are getting 0.03 percent of money from the 5,000 initial value and for 5 years. The total interest is $750.

Answer:

f is decreasing on the interval from x = 1 to x = 2.

Step-by-step explanation:

f has a relative minimum when f' changes signs from - to +.

f has a relative maximum when f' changes signs from + to -.

f is decreasing when f' is negative.

f' is not changing signs at x=-1.5 or x=1.5, so neither of these are minimums or maximums of f.  However, f does have relative minimums at x=-3 and x=2, and a relative maximum at x=1

f' is negative between x=1 and x=2.  So f is decreasing in this interval.

Answer:

The area he can cover with that weapon is 1,256 miles².

Step-by-step explanation:

Assuming that the Jedi won't move and that he can shoot in every direction, he'd be shooting at a circle with a radius of 20 miles. Therefore the are that he can cover with that weapon is the area of the circle, which is shown below:

area = pi*r²

area = 3.14*(20)²

area = 3.14*400

area = 1,256 miles²

The area he can cover with that weapon is 1,256 miles².

The area a projectile can land in can be determined by considering the distance the missile can travel as the circle's radius. The area of this circle, calculated by the formula A = πr², is the area the shell can land in.

The area where the projectile can land is determined by considering the weapon as the centre of a circle and the possible distance it can travel as the radius. This forms a circular area where the projectile can land. The area A of a process is calculated using the formula A = πr², where r is the circle's radius.

Here, our radius is 20 miles, the distance the projectile can travel. Therefore, we substitute this distance into our formula to find the area:

A = π(20)²

Calculating the above will give you the area that the projectile can land in.

The arc length of a partial circle can be calculated using the formula Arc length = (θ/360) * 2πr, where 'θ' is the angle of the sector in degrees and 'r' is the radius of the circle. This is applicable in high school Mathematics.

The subject of your question is the arc length of a partial circle, a concept in Mathematics. The arc length of a partial circle can be calculated using the formula: Arc length = (θ/360) * 2πr, where 'θ' is the angle of the sector in degrees and 'r' is the radius of the circle.

For instance, if a circle has a radius of 8 units and the angle of the sector is 60 degrees, the arc length can be calculated as follows: Arc length = (60/360) * 2 * 3.14 * 8 = 8.38 units (in terms of 3.14 for n π). Using n π, the exact answer would be expressed as: Arc Length = 4π/3 units.

Answer:

3 dogs, $15

5 dogs, $25

Step-by-step explanation:

Jane charges $5 per dog.

When she walks 3 dogs ;

1 dog = $5

3 dogs = x

x × 1 dog = $5 × 3 dogs

x= $5 × 3 dogs/ 1 dog

x= $5 × 3 = $15

When Jane Walks 5 dogs she receives,

y= $5 × 5

y= #25.

For 3 dogs, Jane would charge $15. For 5 dogs, she would charge $25. You find these amounts by multiplying the number of dogs by the charge per dog, which is $5.

Since Jane charges $5 for each dog she walks, you can find the charge for any number of dogs by multiplying the number of dogs by 5.

For 3 dogs, she would charge $15 (3 dogs x $5 per dog = $15).

For 5 dogs, she would charge $25 (5 dogs x $5 per dog = $25).

So, the completed table would look like this:
Dogs | Charge in dollars
1 |$5
3 |$15
5 |$25

Each pizza slice has an area of approximately 12.82 square inches, rounded to the nearest hundredth.

To find the area of each pizza slice, we first need to find the total area of the pizza and then divide it by the number of slices.

The formula for the area of a circle is [tex]\( A = \pi r^2 \)[/tex], where [tex]\( \pi \)[/tex] is approximately 3.14 and r is the radius of the circle.

Given that the radius of the pizza is 7 inches, we can calculate the total area of the pizza:

[tex]\[ A_{\text{total}} = \pi \times (7)^2 \]\[ A_{\text{total}} = 3.14 \times 49 \]\[ A_{\text{total}} \approx 153.86 \text{ square inches} \][/tex]

Now, to find the area of each pizza slice, we divide the total area by the number of slices (12):

[tex]\[ A_{\text{each slice}} = \frac{A_{\text{total}}}{12} \]\[ A_{\text{each slice}} \approx \frac{153.86}{12} \]\[ A_{\text{each slice}} \approx 12.82 \][/tex]

So, the area of each pizza slice is approximately 12.82 square inches.

Answer:

The radius has an increase of 41.4%

Step-by-step explanation:

We have that the surface area formula is equal to:

a = 4 * pi * r ^ 2

in this case if you assume an area of 100 and we calculate the radius it would be:

100 = 4 * pi * r ^ 2

we solve for r:

r ^ 2 = 100/4 * pi

r ^ 2 = 100 / (4 * 3.14)

r ^ 2 = 7.9617

r = 2,822

now if we double the area, that is 200:

r ^ 2 = 200 / (4 * 3.14)

r ^ 2 = 15.9236

r = 3,990

So the change of the radius would be:

3.99 / 2,822 = 1,414

That is to say that the radius has an increase of 41.4%

Answer: 0.15km/min and 0.3km in 2 mins

Step-by-step explanation:

Given Data:

Cyclists speed = 9km/hr

1. Some traveling 60 km/h is traveling one km/min

60/60= 1 km/min

Rate in km/min

= 9km/hr / 60min

= 3/20 km/min

= 0.15 km/min

Kilometers travelled in 2mins

= 2 / 60

= 1 / 30

= 9km/hr * 1 / 30

= 9 / 30

= 0.3 km in 2mins

Answer:

Rate(in km/min) = 0.15 km/min

Distance traveled in 2 mins = 0.3 km

Step-by-step explanation:

Rate = 9 km/hr

1 hr = 60 mins

In 60 minutes, the cyclist rides 9 km

in 1 minute, the cyclist will ride 9/60 km

Therefore, the rate in km/min = 9/60 km/min

Rate(in km/min) = 0.15 km/min

Since the cyclist rides 0.15 km in 1 min,

In 2 mins, the cyclist will ride 0.15 * 2 km = 0.3 km

Distance traveled in 2 mins = 0.3 km

Answer:

[tex]\frac{23}{24}[/tex]

Step-by-step explanation:

1/8 of the stones in Johnny's bowl are red and 5/6 of the stones are white.

The fraction of stones that are red or white is obtained by adding the fraction that are red with the fraction that are white. That is:

[tex]\frac{1}{8} + \frac{5}{6} = \frac{23}{24}[/tex]

The fraction of the stones that are red or white is [tex]\frac{23}{24}[/tex].

Follow below steps:

The fraction of Johnny's stones that are white or red can be calculated by adding the fractions of white and red stones.

Given that 1/8 of the stones are red and 5/6 of the stones are white:

Red stones: 1/8

White stones: 5/6

Total fraction of white or red stones: 1/8 + 5/6 = 5/24 + 20/24 = 25/24

Since the total is greater than 1, it indicates a mistake in the initial information provided.

Answer:

$61

Step-by-step explanation:

To determine the cost per person to attend these events, you have to add the cost of the tickets for the concert plus the cost of the tickets for dinner theater. After finding the total amount that was spent, you have to divide this by 4 that is the number of people:

Total cost= $104+$140

Total cost= $244

Cost per person= $244/4

Cost per person= $61

According to this, the cost per person to attend these events is $61.

Answer:

Cost of first event: $26 per person

Cost of second event: $35 per person

Cost of both events together: $61 per person

Step-by-step explanation:

In the first event, the four people spent $104, so the cost per person of this event is:

104 / 4 = $26

Each person pays $26 for this event.

For the second event, the four people spent $140, so the cost per person of this event is:

140 / 4 = $35

The cost per person to attend both events together is:

26 + 35 = $61
