Answer: 8 = 1x + 2y

Step-by-step explanation:

this could be multiple answers, is this a multiple-choice question? follow that equation to find the answer that fits.

I got the equation by these steps:

total money spent is $8, so you start with 8 =

you don't know the specific number of pens so make that x. the cost of pens is $1, so the total cost will be $1 times however many pencils are bought, ie 1x.

repeat that for pencils, replacing $1 with $2, and making pencils mean y. you get 2y.

now to find your answer, insert numbers into x and y until they equal 8.

possible answers:

x=4, y=1

x=2, y=2

x=0, y=4

Answer:

If the slope of a line is negative, it means that the line is sloping downward from left to right. In other words, as the value of x increases, the value of y decreases. This is in contrast to a positive slope, where as the value of x increases, the value of y also increases. So, if the slope of the line y = x is changed to a negative value, the line will still have the same general shape, but it will be flipped upside-down and will slope downward from left to right

The missing length and the missing angle are approximately 40.447 and 20.034°.

In this question we have a geometric system formed by a equilateral triangle divided into two triangles by a line segment. The missing sides and angles can be found by means of algebra properties, Euclidean geometry and trigonometry.

First, obtain the missing side by taking approach of properties for equilateral triangles:

y = 46 - 16

y = 30

Second, find the length of line segment by law of cosine:

l = √(46² + 16² - 2 · 46 · 16 · cos 60°)

l ≈ 40.447

The missing length is approximately 40.447.

Third, the measure of the missing angle by law of sine:

16 / sin x = 40.447 / sin 60°

sin x = (16 / 40.447) · sin 60°

sin x = 0.343

x ≈ 20.034°

  (c)  F

Step-by-step explanation:

You want the different names for the angles shown, and for their parts.

This question is about naming bits of geometry. Here, you're mainly naming rays and combinations that form angles. A ray is always named by naming its end point first, then another point on the ray. An angle is formed by two rays with a common end point.

An angle can be named by naming rays that form it (with the vertex in the middle of the name), by naming the vertex alone (if that is unambiguous), or by using a designator, such as ∠2.

Angle 2 is made from rays FH and FE, so can be named either of ...

If ray FG were not present, it could also be named angle F, the name of the vertex point.

The 3-letter angle name tells you the names of the sides. The end point of each ray must be named first in the ray name. It is named in the middle of the angle name.

The vertex of angle 1 is the point that is also the vertex of angle 2:

a. The orthocenter for the coordinates (0,0), (6,3), and (3,24) is (24, 2).

b. The orthocenter for the coordinates (5,3), (8,6), and (4,10) is (8, 6).

The orthocenter is the point where the altitudes of the triangle coincide. An obtuse triangle, will be outside the triangle. For a right triangle, it will be the right angle vertex. Of course, each altitude is a line through a vertex and perpendicular to the opposite side.

The equation can be written as,

y -y₃= -(x₂ -x₁)/(y₂ -y₁)(x -x₃)

This can be rearranged to something resembling standard form:

(x₂ -1x₁)(x -x₃) +(y₂-y₁)(y -y₃) = 0

(x₂ -x₁)x +(y₂ -y₁)y = (x₂ -x1)x₃ +(y₂ -y1)y₃ . . . . line through P3, ⊥ to P1P2

Part(a).

For the first altitude, we choose P1 = (0, 0), P2 = (7, 3), and P3 = (3, 51). This gives,

(x₂-x₁) = 7 -0 = 7

(y₂ -y₁) = 3 -0 = 3

altitude equation = 7x +3y = 7·3 +3·51 = 174

For the second altitude, we choose P1 = (0, 0), P2 = (3, 51), and P3 = (7, 3). This gives,

(x₂ -x₁) = 3 -0 = 3

(y₂ -y₁) = 51 -0 = 51

altitude equation = 3x +51y = 3·7 +51·3 = 174

Finding the point of intersection of these two equations can be done in a number of ways. Cramer's Rule provides a quick solution:

x = ((3)(-174) -(51)(-174))/(7·51 -3·3) = 8352/348 = 24

y = ((-174)(3) -(-174)(7))/348 = 696/348 = 2

The orthocenter for the triangle is (24, 2).

Part(b).

We can use the method just described, or we can verify the triangle is a right triangle, as it appears to be when the points are plotted.

The slope of P1P2 is (6 -3)/(8 -5) = 3/3/ = 1.

The slope of P2P3 is (10 -6)/(4 -8) = 4/-4 = -1

These slopes have a product of -1, so the segments are perpendicular. The vertex P2 has the right angle, hence the orthocenter.

The weight of 45 gallons of fuel is 2412 pounds.

What is weight ?

The force exerted on an object by gravity is known as the weight of the object in science and engineering. The gravitational force acting on the item is referred to as weight in several common textbooks. Some people refer to weight as a scalar quantity that measures the gravitational force's strength.

Weight is a gauge of how strongly gravity is pulling something down. It relies on the mass of the item and the acceleration brought on by gravity, which on Earth is 9.8 m/s2. F = m 9.8 m/s2 is the formula for computing weight, where m is the object's mass in kilograms and N is the object's weight in Newtons (N).

The weight of one gallon is

w = (2296 - 2122) / (35 - 20)

   =  174 / 17

   = 11.6 pounds

Now, to answer the question, we need to add the weight of (45-35) = 10 gallons of fuel to the weight of the plane

carrying 35 gallons of fuel, 2296 pounds.

So, the answer is 2296 + 10*11.6

The distance between the dog and its owner when the dog is 46 meters at the northernmost point of the track.

As per the question, the circumference of the circular track is

⇒ 2 × 3.14 × 14 = 87.92 meters.

Since the dog is running at a constant speed of 9 meters per second, it will take the dog 87.92 / 9 = 9.77 seconds to complete one lap of the track.

The angle θ is defined as the angle between the position of the dog and the position of the owner, measured from the center of the track.

Since the track is circular, the angle theta will change at a constant rate of 360 degrees per lap. Since it takes the dog 9.77 seconds to complete one lap, the rate at which the angle θ is changing is 360 / 9.77 = 36.9 degrees per second.

To answer the second question, we must first calculate the distance between the dog and its owner when the dog is at the northernmost point of the track.

The owner is standing a distance of 48 meters from the center of the track, and the radius of the track is 14 meters, the distance between the dog and its owner is given by the Pythagorean theorem: d = √(48² - 14²) = 46 meters.

The domain is the set of all possible input values (x-values).

The range is the set of all possible output values (y-values).

From inspection of the graph, the endpoints of the continuous curve are:

As the endpoints are open circles, the x-values are excluded from the domain.  Therefore, the domain in interval notation is:

The smallest y-value is y = -6 and the greatest y-value is y = 2.  

y = -6 is excluded from the range since it is the y-value of the open circle endpoint, whereas y = 2 is included in the range.  Therefore, the range in interval notation is:

The graph is a function as is each input (x-value) is related to exactly one output (y-value).

From inspection of the graph, the endpoints of the continuous line are:

As the graph is a straight line, the x and y values of the endpoints are the x and y values of the domain and range.

As the (-6, -1) endpoint is an open circle, the values are excluded from the domain and range.

As the (6, 5) endpoint is a closed circle, the values are included in the domain and range.

Therefore, the domain and range in interval notation are:

The graph is a function as is each input (x-value) is related to exactly one output (y-value).

Formula we use,

→ Slope = (y2 - y1)/(x2 - x1)

Now required slope will be,

→ m = (y2 - y1)/(x2 - x1)

Answer:

Jacks Rate: 3 miles per hour

Jills Rate: 4.5 miles per hour

Time: 40 minutes or 2/3 of an hour

Step-by-step explanation:

This problem in it self isn't necessarily too complex, but a crucial part of it is taking the context given and somehow making that into a algebraic expression which we can then use to solve the equation.

So let's first assign two unknowns to the rates at which Jack and Jill walk. Since both of there names start with J, I'll use a subscript to differentiate between the two.

[tex]\text{let }J_a=\text{Jack's walking rate}\\\text{let }J_i = \text{Jill's walking rate}[/tex]

Notice that both have a J, but there is a little letter to the right and below, which is a subscript. This way we can easily tell which person we are referring to while not having to write out their entire name as a variable.

Now let's assign two variables. First let's assign distance: [tex]D=\text{distance from top of hill}[/tex]

and let's also assign time to a variable: [tex]t = \text{time in hours}[/tex]

Now let's start making some equations! If jack is two miles away from the top of the hill, in general, the distance from the hill can be calculated using the following equation: [tex]D=2-t*j_a[/tex]

Essentially, Jack starts off with a distance of two miles away, and after one hour, Jack will walk [tex]j_a[/tex] miles, this is his rate, what Jake travels in one hour. After another hour passes, he will do the same thing, but twice. So this is why we're multiplying by time. Since for each hour that passes, he will walk a further: [tex]j_a[/tex] miles, meaning he will be that much closer, so we subtract it from 2, the initial distance.

The same logic can be applied to Jill, except with an initial distance of 3 miles and using the unknown: [tex]j_i[/tex] which is Jill's rate. So we get the following equation: [tex]D=3-t*j_i[/tex]

If we're looking for when they reach the top of the hill, that means that the distance from the hill is zero. So let's set both equations to zero.

[tex]0=3-t*j_i\\0=2-t*j_a[/tex]

From here let's solve for time for both equations. So let's start with the first equation.

[tex]0=3-t*j_i[/tex]

From here let's subtract 3 from both sides to get rid of the 3 on the right side.

[tex]0-3=(3-3)-t*j_i\implies-3=-t*j_i[/tex]

from here let's divide both sides by Jill's rate.

[tex]\frac{-3}{j_i} = \frac{-t*j_i}{j_i} \implies \frac{-3}{j_i}=-t[/tex]

From here let's divide both sides by -1 to get t isolated.

[tex]\frac{\frac{-3}{j_i}}{-1} = \frac{-t}{-1} \implies \frac{3}{j_i}=t[/tex]

We can essentially apply the same steps to the equation we derived from Jack's rate.

[tex]0=2-t*j_a\\\\(0-2)=(2-2)-t*j_a \implies -2 = -t*j_a\\\\ \frac{-2}{j_a} = \frac{-t}{j_a} \implies \frac{-2}{j_a} = -t\\\\\frac{\frac{-2}{j_a}}{-1} = \frac{-t}{-1} \implies \frac{2}{j_a} = t[/tex]

Now we have the equations:

[tex]\frac{2}{j_a} = t\\\\\frac{3}{j_i} = t[/tex]

and this represents the time needed to reach the top of the hill (since we set both equations equal to zero)

From here we need to look once more at the question, specifically where it says: "It takes them the same amount of time to get there". So we set the equations equal to each other.

[tex]\frac{2}{j_a} = \frac{3}{j_i}[/tex]

Now we use our last piece of needed context: "Jill walks 1.5 miles per hour faster than Jack".  We can set up one more equation: [tex]J_i = J_a+1.5[/tex].

This is super useful to have, since we can now make a substitution give this equation, converting our two-variable equation into a one-variable equation, allowing us to solve for one numerical value.

We have: [tex]\frac{2}{j_a} = \frac{3}{j_i}[/tex] and we know that: [tex]J_i = J_a+1.5[/tex], so let's simply plug in [tex]J_a+1.5[/tex] for [tex]j_i[/tex].

This gives us the equation:

[tex]\frac{2}{J_a}= \frac{3}{J_a + 1.5}[/tex].

Cross Multiply:

[tex]2(J_a+1.5) = 3(J_a) \implies 2J_a + 3 = 3J_a[/tex].

Subtract [tex]2J_a[/tex]:

[tex]3=J_a[/tex].  

We can solve for Jills value, since Jill's value is just 1.5 miles per hour more than this, so [tex]J_i = 3+1.5=4.5[/tex]

Now let's take Jacks value and substitute it into his time equation

[tex]t = \frac{2}{3}[/tex]

we can keep this in hours, or we can convert this into minutes. We can convert this in to minutes by multiplying the amount of minutes in an hour by 2/3, so: [tex]60 * \frac{2}{3} = \frac{120}{3} = 40\text{ minutes}[/tex]

Answer:

To maximize profit, the Banana Apple company should determine the number of each kind of apple box that they should make. To do this, they need to know the number of each type of apple that they have, as well as the price of each box.

Based on the information provided, the company has 2800 Golden apples, 2200 Macintosh apples, and 2300 Red Ida apples. This means that they can make 700 Box A's (2800 / 4 = 700), 1100 Box B's (2200 / 2 = 1100), and 575 Box C's (2300 / 4 = 575).

The price of each box is also given: Box A costs 3€, Box B costs 3€, and Box C costs 4€. This means that if the company makes 700 Box A's, they will earn 2100€ (700 x 3 = 2100€), if they make 1100 Box B's, they will earn 3300€ (1100 x 3 = 3300€), and if they make 575 Box C's, they will earn 2300€ (575 x 4 = 2300€).

To maximize profit, the company should make as many of the most profitable box as possible. In this case, the most profitable box is Box B, which earns 3€ per box. The company should make 1100 Box B's, which will earn them a total of 3300€.

Answer:

To solve this problem, we need to determine how many boxes of each type the company should make to maximize their profit. We can set up a system of equations to represent the number of apples in each box and the total number of apples the company has.

Let's call the number of boxes of type A x, the number of boxes of type B y, and the number of boxes of type C z. We can represent the number of apples in each box using the following equations:

x + y + z = 2800

4x + 6y + 0z = 2200

2x + 2y + 6z = 2300

To maximize the profit, the company should make as many boxes as possible while still having enough apples to fill all the boxes. We can solve this system of equations using substitution to find the values of x, y, and z that maximize the profit.

First, we can solve the first equation for z in terms of x and y:

z = 2800 - x - y

Next, we can substitute this expression for z into the second and third equations to eliminate z:

4x + 6y + 0(2800 - x - y) = 2200

4x + 6y = 2200

2x + 2y + 6(2800 - x - y) = 2300

2x + 2y + 17600 - 6x - 6y = 2300

2x + 2y = -15300

We can then solve this system of equations using substitution. From the second equation, we have:

4x + 6y = 2200

2x + 2y = -15300

We can solve the second equation for y in terms of x:

y = -15300/2 - x/2

We can substitute this expression for y into the first equation to solve for x:

4x + 6(-15300/2 - x/2) = 2200

4x - 45300 - 3x = 2200

x = (2200 + 45300) / (4 - 3)

x = 13600/1

x = 13600

We can then use this value of x to find the value of y:

y = -15300/2 - 13600/2

y = -13650

Finally, we can use these values of x and y to find the value of z:

z = 2800 - 13600 - (-13650)

z = 1650

Therefore, the company should make 13600 boxes of type A, -13650 boxes of type B, and 1650 boxes of type C to maximize their profit.
