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.

m <1 = 30

Step-by-step explanation:

The sum of the angles of a triangle add to 180

Let x be the unknown angle

75+75+x = 180

Combine like terms

150+x =180

Subtract 150 from each side

150-150+x = 180-150

x = 30

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:

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

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:

$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

Step-by-step explanation:

You can get 12 servings of 2/3 cup each from an 8-cup container of juice. You find this by dividing the total volume (8 cups) by the volume of each serving (2/3 cup).

To find out how many 2/3 cup servings you can get from an 8-cup container of juice, you simply divide the total volume by the volume of each serving.

In this case, you divide 8 (the total volume) by 2/3 (the volume of each serving). Here are the step-by-step calculations:

Final answer:

To find the width of the image on the tablet, set up a proportion using the diagonals of the computer monitor and the tablet. Solve for the unknown width using cross multiplication.So,on tablet it would be 0.84mm.

Explanation:

To determine the width of the image on the tablet, we can use a proportion based on the diagonals of the computer monitor and the tablet. The proportion can be set up as follows:

Computer Diagonal / Tablet Diagonal = Computer Width / Tablet Width

Substituting the given values, we have:

21 inches / 9.1 inches = 19 centimeters / x

Cross multiplying and solving for x, we get:

x = (9.1 inches * 19 centimeters) / 21 inches

Converting the units, the width of the image on the tablet should be approximately 8.43 centimeters=0.84mm

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: 1.57

Step-by-step explanation:

When solving for the arc you have to find the circumference.

For circumference you'll need the diameter which is 2x the radius.

So, your equation would be

or

1/4{(3.14)(2)} = x

To Solve:

3.14 times 2 equals 6.28

Divide by 4 or multiply by 1/4 to get 1.57

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:

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:

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.
