Answer:

Step-by-step explanation:

the formula for finding  the volume of a cone would be V= 3.14 r sqaured * h/3

so plug that in and it would be   3.14(5.1) sqaured * 13/3

3.14 is the formula of pie which is in the formula for finding the volume of

5.1*5.1=  26.01

3.14* 26.01= 81.67    

13/3= 4.34

81.67* 4.34= 354.45

The volume of a right circular cone that has a height of 13 in and a base with a circumference of 5.1 inches is 8.97824.

Since

We know that

Volume = [tex]\pi r^2 \frac{h}{3}[/tex]

Since the circumference is 5.1 inches

So here the radius be like

Circumference = [tex]2\pi r[/tex]

5.1 = 2(3.14) r

r = 0.8121

Now the volume should be

[tex]= 3.14 \times (0.8121)^2 \frac{13}{3}[/tex]

= 8.97824

Hence, The volume of a right circular cone that has a height of 13 in and a base with a circumference of 5.1 inches is 8.97824.

Answer:

yoy didnt put a picture of the answer choices, so I'm not sure which one this would be, but the answer would be C=5 + .72P

Step-by-step explanation:

C is the total cost, so that would be on the opposite side of the equal sign from P. the 5 would be the constant, since that is the starting price for all packages, and the .72 is the price per pound, so you would have to multiply .72 by P pounds in order to complete the equation.

Answer:

x = 20, the number of chickens as well as the number of ducks.

........

20 chickens, 20 ducks and 10 Dogs 50-20-20

And...checking

$400 + $600 + $500 = 1500

x the number of chickens as well as the number of ducks

20x + 30x + 50(50-2x) = $1500

-50x = -1000

Step-by-step explanation:

Hope this helps

The system of 3 equations to model the situation are;

x + y + z = 50

20x + 50y + 30z = 1500

x = z

The equation:

x + y + z = 50

20x + 50y + 30z = 1500

number of chicken = number of ducks

x = z

Therefore, the equations are;

x + y + z = 50

20x + 50y + 30z = 1500

x = z

Answer: The equation is

The cost of 18 roses is 53.10.

Step-by-step explanation:

Given:

A florist sells a dozen roses for 35.40. She sells individual roses for the same unit price.

Now, to find the cost of 18 roses and write an equation to represent the relationship between the number of roses, x, and the total cost of the roses, y.

1 dozen = 12.

Now, to get the cost of 18 roses we use unitary method:

If 12 roses cost = 35.40.

So, 1 roses cost = 2.95.

Thus, 18 roses cost = 53.10.

Therefore, the cost of 18 roses = 53.10.

Now, to write an equation the relationship between the number of roses and the total cost of the roses:

Cost of per rose = 2.95.

As, given in question:

Number of roses =

Total cost of the roses =

Total cost of the roses = Cost of per rose × Number of roses.

So, the equation is:

Therefore, the equation is And the cost of 18 roses is 53.10.

Answer:  One face is 16 square centimeters.

Step-by-step explanation: To find the area of a face, you need to know the length of the side. All the sides of the cube are the same, so take the cube root of 64.

[tex]\sqrt[3]{64}=4[/tex] cm is the length of the side

The area of one face is the side length squared 4² = 16

4cm × 4cm = 16 square centimeters.

Answer:

surface area of one face of the cube will be 16 cm².

Step-by-step explanation:

Cassie has a small cube shaped box.

Volume of the box is 64 cm³

We have to find the area of one face of the box.

Let one side of the box is x

Then volume = x³ = 64

                       x³ = 4³

                       x = 4

Now area of one face of the cube = x²

     then area = 4² = 16 cm²

Therefore, surface area of one face of the cube will be 16 cm².

Answer:

The $6.03 for 7 bags of ice is a better deal

Step-by-step explanation:

In order to find out which is a better deal we find the unit price.

To find the unit price we do the cost divided by how many bags of ice.

6.02 divided by 7 = 0.86, so the unit price is 0.86/1

5.52 divided by 6 = 0.92, so the unit price is 0.92/1

Finally, we can see which has a lower unit price which is the $6.03 for 7 bags of ice

S=$1800+$110*N

t = 1.5 x 4

t = 6
