Answer:

6 cups

Step-by-step explanation:

When two things are directly proportional (e.g. y and x), we can model the relationship with the direct variation equation, which is

y = kx, where

Step 1:  To find k, we can allow y to represent Jackie's total revenue from selling lemonade ($9) and x to represent the quantity of cups of lemonade sold ($3):

9 = 3k

k = 3

Step 2:  Now that we've found the constant of proportionality, we can plug in 18 for y and 3 for k, allowing us to solve for x:

18 = 3x

6 = x

Thus, in order for Jackie to earn $18, she must sell 6 cups in all.

Nakeisha sold 8 lollipops and 5 fruit snacks yesterday to earn a total of $18.25.

Let's use a system of equations to solve this problem. Let x be the number of lollipops sold and y be the number of fruit snacks sold. From the problem, we know that:
- The price of each lollipop is $1.50, so the total amount of money earned from selling x lollipops is 1.5x.
- The price of each fruit snack is $1.25, so the total amount of money earned from selling y fruit snacks is 1.25y.
- Yesterday, Nakeisha made $18.25 from selling a total of 13 lollipops and fruit snacks, so we can write the equation:
1.5x + 1.25y = 18.25
We also know that Nakeisha sold a total of 13 lollipops and fruit snacks, so we can write the equation:
x + y = 13
Now we have two equations with two variables, which we can solve using substitution or elimination. Let's use substitution:
- Rearrange the second equation to solve for one variable in terms of the other:
x + y = 13
y = 13 - x
- Substitute y = 13 - x into the first equation:
1.5x + 1.25y = 18.25
1.5x + 1.25(13 - x) = 18.25
- Simplify and solve for x:
1.5x + 16.25 - 1.25x = 18.25
0.25x = 2
x = 8
- Substitute x = 8 back into y = 13 - x to find y:
y = 13 - x
y = 13 - 8
y = 5
Therefore, Nakeisha sold 8 lollipops and 5 fruit snacks yesterday to earn a total of $18.25.

The view factor from the 2 cm side to the 4 cm side of the infinitely long three-sided triangular enclosure is approximately 0.5.

The view factor (F) from Surface A to Surface B can be calculated using the formula:

F = A / (A + B)

where A and B are the areas of Surface A and Surface B, respectively.

The area of a triangle can be calculated using Heron's formula:

Area = sqrt(s * (s - a) * (s - b) * (s - c))

where s is the semi-perimeter of the triangle and a, b, and c are the side lengths of the triangle.

For Surface A:

a = 2 cm

b = 3 cm

c = 4 cm

s = (a + b + c) / 2 = (2 + 3 + 4) / 2 = 4.5 cm

Area_A = sqrt(4.5 * (4.5 - 2) * (4.5 - 3) * (4.5 - 4))

= √(4.5 * 2.5 * 1.5 * 0.5)

=√(5.625) ≈ 2.37 cm²

For Surface B:

a = 2 cm

b = 4 cm

c = 3 cm

s = (a + b + c) / 2 = (2 + 4 + 3) / 2 = 4.5 cm

Area_B = √(4.5 * (4.5 - 2) * (4.5 - 4) * (4.5 - 3))

= √(4.5 * 2.5 * 0.5 * 1.5)

=√(5.625) ≈ 2.37 cm²

Now we can calculate the view factor (F):

F = Area_A / (Area_A + Area_B)

= 2.37 / (2.37 + 2.37)

≈ 0.5

Therefore, the view factor from the 2 cm side to the 4 cm side of the infinitely long three-sided triangular enclosure is approximately 0.5.

Answer:

20 water fountains can be made when the cost is 770.

Verbal statement: The cost equals 30 times the fountains for cats plus 170

Step-by-step explanation:

Lets review the defined variables.

f = fountains for cats

C = cost

We are given the value of the cost, but not the amount of fountains for cats. This means we will have to solve for f in the equation.

Substitute 770 for C

[tex]770=30f+170[/tex]

Subtract 170 on both sides

[tex]600=30f[/tex]

Divide by 30

[tex]20=f[/tex]

20 water fountains can be made when the cost is 770.

To prove this, plug our numbers into the expression.

The correct option for the demand requirement constraint in a production scheduling LP is option (c): beginning inventory + production - ending inventory = demand.

In a production scheduling LP, the demand requirement constraint represents the balance between the available inventory and the demand for the product. The constraint ensures that the production and inventory levels are sufficient to meet the specified demand.

Option (c) represents this relationship accurately by stating that the beginning inventory, production, and ending inventory, when subtracted from each other, should equal the demand. This equation reflects the concept of maintaining a balance between the production output and inventory changes to meet the demand

Option (a) is incorrect because it uses the greater than or equal to (≥) symbol, which does not accurately represent the constraint.

Option (b) is also incorrect because it uses the equality (=) symbol, which implies an exact balance between the inventory and demand, disregarding the changes in inventory.

Option (d) is incorrect because it uses the greater than or equal to (≥) symbol, which does not accurately represent the constraint.

Therefore, option (c) is the correct representation of the demand requirement constraint in a production scheduling LP.

2.5(6.25x + 0.5) = 11

15.625x + 1.25 = 11

The correct reason for line 4 of Raya's solution is the Distributive property of equality. This property states that for any real numbers a, b, and c, a(b + c) = ab + ac. In line 4 of Raya's solution, the Distributive property is applied to distribute 2.5 to the terms inside the parentheses (6.25x and 0.5).

To see why the Distributive property is used, let's consider the expression 2.5(6.25x + 0.5). To simplify this expression, we can use the Distributive property as follows:

2.5(6.25x + 0.5) = 2.5(6.25x) + 2.5(0.5)

Now, we can use the Multiplication property of equality to simplify the expression further:

15.625x + 1.25 = 11

This means that 15.625x + 1.25 is equal to 11, and we can continue solving for x.

In summary, the Distributive property of equality is used to simplify expressions by distributing a factor to the terms inside parentheses.

Of all the milkshakes sold at Ezra's Ice Cream Shops, 59.29% were sold at the old store.

To calculate the percentages, we need to find the conditional probabilities based on the given information.

Let's calculate the percentages step by step:

Customers at the old store bought milkshakes about:

Milkshakes sold at the old store = 13,400

Total sales at the old store

= 52,100 (Ice Cream) + 13,400 (Milkshakes) = 65,500

Percentage

= (Milkshakes sold at the old store / Total sales at the old store) x 100

Percentage = (13,400 / 65,500) x 100 ≈ 20.46%

Customers at the new store bought milkshakes about:

Milkshakes sold at the new store = 9,200

Total sales at the new store = 25,800 (Ice Cream) + 9,200 (Milkshakes) = 35,000

Percentage = (Milkshakes sold at the new store / Total sales at the new store) x 100

Percentage = (9,200 / 35,000) * 100 ≈ 26.29%

Of all the milkshakes sold at Ezra's Ice Cream Shops, the percentage sold at the old store:

Total milkshakes sold at both stores = Milkshakes sold at the old store + Milkshakes sold at the new store = 13,400 + 9,200 = 22,600

To find the perimeter of a scale drawing, we need to use the same scale factor that was used to create the drawing. In this case, the scale factor is 7 inches: 28 feet, or 1 inch: 4 feet. This means that every inch in the drawing represents 4 feet in the actual floor.

To find the perimeter of the floor in the scale drawing, we need to add up the lengths of all the sides. Since the floor is rectangular, it has two pairs of equal sides. The length of the floor is 28 feet, so the length of the scale drawing is 28 / 4 = 7 inches. The width of the floor is 24 feet, so the width of the scale drawing is 24 / 4 = 6 inches.
