Answer:

Frosts second mile and steadys 6th mike

Step-by-step explanation:

Part A: The two plans will cost the same amount when the distance to the airport is 12 miles.

Part B: For a 20-mile distance, Mr. Gardner should choose Fost Shuttle, costing $10 compared to $12 for Steady Shuttle.

Let's solve Part A first:

Part A:

Let's denote the distance to the airport as d miles.

For Fost Shuttle:

Cost = Pick-up fee + Cost per mile × Distance

Cost = $5 + $0.25 × d

For Steady Shuttle:

Cost = Pick-up fee + Cost per mile × Distance

Cost = $2 + $0.50 × d

Now, we'll set up an equation to find when the two plans cost the same amount:

[tex]\[5 + 0.25d = 2 + 0.50d\][/tex]

Solving for d:

[tex]\[0.25d - 0.50d = 2 - 5\]\[-0.25d = -3\]\[d = \frac{-3}{-0.25}\]\[d = 12\][/tex]

So, the two plans will cost the same amount when the distance is 12 miles.

For Part B:

Given the distance is 20 miles, let's calculate the cost for each company:

For Fost Shuttle:

Cost = $5 + $0.25 × 20 = $5 + $5 = $10

For Steady Shuttle:

Cost = $2 + $0.50 × 20 = $2 + $10 = $12

Comparing the costs, Mr. Gardner should choose Fost Shuttle as it costs $10 compared to $12 for Steady Shuttle.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the time in seconds

y ---> the distance in meters

In this problem we have a proportional relationship between the variables x and y

Find the constant of proportionality k

[tex]k=\frac{y}{x}[/tex]

For x=2, y=25 ---> [tex]k=\frac{25}{2}=12.5[/tex]

For x=4, y=50 ---> [tex]k=\frac{50}{4}=12.5[/tex]

For x=6, y=75 ---> [tex]k=\frac{75}{6}=12.5[/tex]

For x=8, y=100 ---> [tex]k=\frac{100}{8}=12.5[/tex]

so

The value of k is [tex]12.5\ \frac{m}{sec}[/tex]

In this problem the value of k or slope represent the speed of the train

The linear equation is equal to

[tex]y=12.5x[/tex]

Answer:

The total weight of the water in a full tank, to the nearest pound is 3527 pounds per cubic foot

Step-by-step explanation:

Given:

Diameter  of the hemispherical tank = 6 feet

Weight of water per cubic foot =  62. 4 pounds

To Find:

The total weight of the water in a full tank, to the nearest pound?

Solution:

We know that the volume of a sphere is:

[tex]V =\frac{4}{3}\pi r^3[/tex]

where  

r = is the radius

In the question we are given with diameter,

So

[tex]radius = \frac{diameter}{2}[/tex]

radius = [tex]\frac{6}{2}[/tex]

Radius = 3

We need the volume of the hemisphere

So the volume of the hemisphere will be half of the volume of teh sphere

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

Thus the volume of the hemisphere is

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

Now substituting the values

[tex]V = \frac{2}{3} \pi(3)^3[/tex]

[tex]V = \frac{2}{3}\pi(27)[/tex]

[tex]V = \frac{54 \pi}{3}[/tex]

[tex]V = \frac{169.56}{2}[/tex]

V=  56.52 cubic foot

Now, the total weight of water of:

W =  56.52 x 62.4

W= 3526.848 pounds per cubic foot

To the nearest pounds

W= 3527 pounds per cubic foot

[tex]=17y(117x^2 + 154x - 475) + 5(117x^2 + 154x - 475)\\=1989x^2y + 585x^2+ 2618xy + 770x - 8075y - 2375[/tex]

Therefore after simplifying , we get

[tex](9x + 25) (13x - 19) (17y + 5)=1989x^2y + 585x^2+ 2618xy + 770x - 8075y - 2375[/tex]

Through algebra, we found that Xavier's current age is 61, which makes Yolanda 65. Subtracting the 40 years of marriage from their current ages, we determined that Yolanda was 25 years old when they got married.

The question given by the student is a problem that can be solved with simple algebra. To find out how old Yolanda was when they married, we first need to establish the current ages of Xavier and Yolanda based on the information given.

Let's denote Xavier's current age as x years. Consequently, Yolanda's current age will be x + 4 years (since she is 4 years older than Xavier). According to the problem, the sum of their ages now is 126 years. We can set up the following equation based on this information:

x + (x + 4) = 126

By solving the equation:

Combine like terms: 2x + 4 = 126

Subtract 4 from both sides: 2x = 122

Divide both sides by 2: x = 61

This means that Xavier is now 61 years old, and Yolanda is x + 4, which is 65 years old. Since they have been married for 40 years, we subtract 40 from their current ages to get their ages at the time they got married. So, Yolanda was 25 years old when she got married.

Final answer:

The independent variable in the scenario is the time spent baking, and the dependent variable is the number of cookies baked. The size of the oven might be another independent variable if comparing productivity between different bakeries.

Explanation:

In the context of the question where a baker bakes 40 cookies in an hour, we are being asked to identify the dependent and independent variables in this scenario. First, let's define these terms:

In this particular case, the independent variable could be the time spent baking, because it is what the baker controls. The dependent variable is the number of cookies baked, which depends on the amount of time the baker spends baking. If, for example, the baker decides to bake for two hours instead of one, we would expect the number of cookies baked to potentially double, assuming productivity remains constant.

In a different scenario, where comparing the productivity of bakers with different oven sizes – such as a Canadian worker with an industrial-size oven versus a U.S. worker with a smaller oven – the size of the oven could be seen as the independent variable affecting the dependent variable of productivity measured by the output of loaves of bread in an hour.

The depth of sun after 5 minutes is 809.82 feet

Solution:

A submarine dives at an angle of 13 degrees to the surface of the water

The submarine travels at a speed of 720 feet per minute

The figure is attached below

ACB is a right angled triangle

AB is the distance between surafce of water and submarine

BC is the depth of submarine

Let "x" be the depth of sun after 5 minutes

Therefore, distance between submarine and surface of water is:

[tex]AB = 720 \frac{feet}{minute} \times 5 \text{minute} = 3600 feet[/tex]

Submarine dives at an angle of 13 degrees to the surface of the water

Therefore, angle A = 13 degrees

Now we have to find BC

By definition of sine,

[tex]sin \theta = \frac{opposite}{hypotenuse}[/tex]

Here, opposite = BC = x

hypotenuse = AB = 3600 feet

Thus, we get,

[tex]sin \theta = \frac{BC}{AB}\\\\sin \theta = \frac{x}{3600}\\\\sin 13 = \frac{x}{3600}\\\\0.2249 = \frac{x}{3600}\\\\x = 3600 \times 0.2249\\\\x = 809.82[/tex]

Thus the depth of sun after 5 minutes is 809.82 feet

Now, to solve it by substitution.

[tex]x=4-2y[/tex]  .....(1)

[tex]3x-2y=4[/tex]  ......(2)

Now, solving the equation (2) by substitution:

[tex]3x-2y=4[/tex]

Substituting the value of [tex]x[/tex] from equation (1):

[tex]3(4-2y)-2y=4[/tex]

[tex]12-6y-2y=4[/tex]

[tex]12-8y=4[/tex]

Subtracting both sides by 12 we get:

By calculating the shipping fees for regular and rush delivery for a 26.5 pound computer, we find that regular shipping saves approximately 14.90 dollars.

We must first calculate the fee for each method and then subtract the regular "shipping fee" from the rush delivery fee to find the savings.

Using the given expression, the regular shipping fee for a 26.5 pound computer is: 0.5*26.5 + 4.49 = 17.74 dollars. Meanwhile, the rush delivery fee for the same computer, using the other given expression, would be: 0.99*26.5 + 6.49 = 32.635 dollars.

Subtracting the regular fee from the rush fee, we find: 32.635 - 17.74 = 14.895 dollars. Therefore, you save about 14.90 dollars by choosing regular shipping over rush delivery.

The store initially bought 82 half gallons of milk.

To solve the problem, we need to find out how many half gallons of milk the store initially bought. We can set up an equation to represent the situation where the cost of milk is subtracted from the sales to find the profit.

Let's assume the store bought x half gallons of milk. Then, the cost of the x half gallons is x multiplied by $2.70:

Cost = 2.70x dollars

The store ruined 12 half gallons, so they can only sell x - 12 half gallons. The revenue from selling each half gallon is $4.02, so the total revenue from selling x - 12 half gallons is:

Revenue = 4.02(x - 12) dollars

We are told the store made a profit of $60, so the revenue minus the cost equals the profit:

4.02(x - 12) - 2.70x = 60

Now we solve for x:

4.02x - 48.24 - 2.70x = 60

1.32x - 48.24 = 60

1.32x = 108.24

x = 82 half gallons

Therefore, the store initially bought 82 half gallons of milk.

Final answer:

The sine of the angle between the ground and the line connecting the top of the shadow to the top of the tree, given a 50-foot tree and a 9-foot shadow, is approximately 0.984, calculated using the definition of sine in a right triangle and the Pythagorean theorem.

Explanation:

The question involves finding the sine of the angle between the ground and the line connecting the top of the shadow to the top of the tree, given that a 50-foot tree casts a 9-foot long shadow. In this scenario, we can visualize a right triangle where the tree represents the opposite side (height), the shadow represents the adjacent side (base), and the hypotenuse is the line from the top of the tree to the end of the shadow on the ground.

To find the sine of the angle, we use the definition of sine in a right triangle, which is sine(angle) = opposite / hypotenuse. However, before we can do that, we need to determine the length of the hypotenuse using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a² + b² = c²).

Let's calculate:

a (opposite) = 50 feet (Height of the tree)

b (adjacent) = 9 feet (Length of the shadow)

c (hypotenuse) = √(50² + 9²) = √(2500 + 81) = √2581 = 50.8 feet (approximately)

Now, we can calculate the sine of the angle:

sine(angle) = opposite / hypotenuse = 50 / 50.8 ≈ 0.984

Therefore, the sine of the angle between the ground and the line connecting the top of the shadow to the top of the tree is approximately 0.984.
