A florist sells a dozen roses for $35.40. She sells individual roses for the same unit cost. Write an equation to represent the relationship between the number of roses, x, and the total cost of the roses, y. How much would 18 roses cost?
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.

Which is a better deal?
An ice company charged $6.02 for 7 bags of ice. If a
convenience store sold 6 bags of ice for $5.52, which is a
better buy?
Explain/Justify your answer
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

Find the volume of a right circular cone that has a height of 13 in and a base with a
circumference of 5.1 in. Round your answer to the nearest tenth of a cubic inch.
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.
Calculation of the volume of right circular cone:
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.

Jane is asked to buy some chickens, dogs and ducks for her farm. The total number of animals she needs to buy is 50. She has a budget of $1500 to spend on $20/chicken, $50/dog, and $30/duck. Additionally, the number of chickens should be equal to that of ducks. Create a system of 3 equations to model the situation. Assume the number of chickens is x, dogs is y and ducks is z.
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
How to write equation?number of chickens = xnumber of dogs = ynumber of ducks = zcost of each chicken = 20cost of each dog = 50cost of each duck = 30Total cost = 1500Total number of animals = 50The 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

You take a package to the local shipping company. They charge $0.72 per pound, and also has a fixed cost of $5
per package. If P represents the number of pounds of your package, and C is the total cost of shipping your
package, which of these is the correct relationship between P and C?
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.

Plant A is 4 inches tall and growing at a rate of 4 centimeters per
week. Plant B is 10 inches tall and growing at a rate of 1 centimeter per
week. After how many weeks will both plants have the same height?
Choose the equation that best represents this situation.
A.) 4 - 4y = 10 - Y
B.) 4 + 4y = 10 + y
C.)4 + y + 4y = 10
D.)4(y + 4y) = 10
Answer:1/2t + 4 = 1/4t + 5.5
1/2t - 1/4t = 5.5 - 4
2/4t - 1/4t = 1.5
1/4t = 1.5
t = 1.5 x 4
t = 6
h = 1/2t + 4
h = 1/2(6) + 4
h = 3 + 4
h = 7
solution is (7,6)
means that the plants will both be 7 cm tall after 6 weeks

Cassie has a small cube shaped box. Its volume is 64 cubic cm. What is the area of one face of tje box.
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.
