The true statement is (b) Xavier used 15 oz of pineapple to with 24 oz of orange juice

From the question, we have the following parameters that can be used in our computation:

The graph that represents the ratio of orange juice to pineapple juice

The graph passes through the origin

So, we have

slope = 16/10

Evaluate

slope = 1.6

When pineapple juice is 15, we have

orange = 15 * 1.6

orange = 24

Hence, the true statement is b

Step-by-step explanation:

15 is not a fraction as is you can put any number over a one and that whole number immediately becomes a fraction:

\(\frac{7}{1} or \frac{43}{1} or \frac{987}{1} or \frac{1}{1} or \frac{15}{1}\)

15/1 is your fraction so 15/1 divided into 15 equals 1

The force required to keep a hockey puck sliding at a constant velocity, neglecting ice friction and air resistance, is equal to its weight. The correct option is "equal to its weight."

When a hockey puck is set in motion across a frozen pond and there is no ice friction or air resistance, the only force acting on the puck is its weight, which is the force due to gravity pulling it downward. According to Newton's first law of motion (the law of inertia), an object at a constant velocity will continue to move at that velocity unless acted upon by an external force.

Since the puck is already in motion and we want to maintain its constant velocity, the force required to counteract its weight and keep it sliding is equal to its weight. This is because the weight of an object is the force exerted on it by gravity, and in the absence of other forces, an equal and opposite force is needed to maintain the object's motion without acceleration.

Answer:

A. \( 82\degree\)

Step-by-step explanation:

By the theorem of intersecting chords inside a circle.

\( m\angle OVU=\frac{1}{2} (m\widehat {GK} +m \widehat {OU}) \)

\( m\angle OVU = \frac{1}{2} (142\degree + 54\degree) \)

\( m\angle OVU=\frac{1}{2} \times 196\degree \)

\( m\angle OVU = 98\degree \)

\( m\angle OVU + m\angle OVU = 180\degree \)

(Linear pair angles)

\(m\angle OVG + 98\degree = 180\degree \)

\( m\angle OVG =180\degree - 98\degree\)

\( m\angle OVG = 82\degree\)

Step-by-step explanation:

A price markdown is a reduction that is deliberate when selling a product. From the question, we are informed that a video game that usually costs $30.65 is marked down 60%.

The find the new price of the video game, we have to subtract the amount reduced from the original price. The amount reduced is:

= 60% of $30.65

= 60/100 × $30.65

= 0.6 × $30.65

= $18.39

The new selling price = $30.65 - $18.39

= $12.26

The error that Kelvin made when he determined that the new price of the game would be $18.39 was that he didn't subtract the value from the original price of the video game.

The equation of the surface of revolution generated by revolving x = (1/z)^z about the z-axis is x = e^(-y).

To find the equation of the surface of revolution, we start with the parametric equation x = (1/z)^z, y = t, z = t. We eliminate the parameter t by substituting z for t in the equation x = (1/z)^z. Simplifying further, we obtain x = e^(-y).

This equation represents the surface of revolution generated by revolving the curve x = (1/z)^z about the z-axis. The exponentiation by e^(-y) signifies that the x-coordinate changes exponentially as the y-coordinate varies.

Therefore, as we revolve the curve around the z-axis, it forms a surface with an exponential decay in the x-direction. Hence, the equation x = e^(-y) describes the surface of revolution.

Answer:

I think the length remains the same

Step-by-step explanation:

The first law of thermodynamics is a fundamental principle in physics that states energy cannot be created or destroyed, only converted from one form to another. It can be expressed in terms of heat and work through the equation:

ΔU = q - w

where ΔU represents the change in internal energy of a system, q represents the heat added to the system, and w represents the work done on or by the system.

Now, let's address when the quantities q and w would be negative numbers.

1) When q is negative: This occurs when heat is removed from the system, indicating an energy loss. For example, when a substance is cooled, heat is extracted from it, resulting in a negative value for q.

2) When w is negative: This occurs when work is done on the system, decreasing its energy. For instance, when compressing a gas, work is done on it, leading to a negative value for w.

In both cases, the negative sign indicates a reduction in energy or the transfer of energy from the system to its surroundings.

In summary, the first law of thermodynamics can be expressed as ΔU = q - w, and q and w can be negative numbers when energy is lost from the system through the removal of heat or when work is done on the system.

A student taking an examination is required to answer exactly 10 out of 15 questions.

(a) In how many ways can the 10 questions be selected?

There are 15 questions and 10 questions are to be selected. The 10 questions can be selected from 15 in (15C10) ways.

Explanation:

Here, the number of ways to select r items out of n is given by nCr, where n is the total number of items, and r is the number of items to be selected. Thus, the required number of ways in which 10 questions can be selected from 15 is:15C10 = 3003.

Answer:

h = 9n

Step-by-step explanation:

Since h (height) is a function of number of DVDs then we can express in the form of:

\(\displaystyle{h = an+b}\)

where h is height, a is rate of change, n is number of DVD and b is the initial height which of course is 0 (proportional). Henceforth, we will be with the equation:

\(\displaystyle{h = an}\)

Next, we will be finding the rate of change of how much the dependent values change with respect to the independent values. That can be expressed as:

\(\displaystyle{a = \dfrac{h_2 - h_1}{n_2-n_1} = \dfrac{\Delta h}{\Delta n}}\)

delta means "change of/in"

We will pick \(\displaystyle{(n_1,h_1) = (2,18)}\) and \(\displaystyle{(n_2, h_2) = (3,27)}\). Therefore, substitute in the rate of change formula:

\(\displaystyle{a = \dfrac{27-18}{3-2}}\\\\\displaystyle{a = \dfrac{9}{1}}\\\\\displaystyle{a = 9}\)

Therefore, the rate of change is 9. Substitute a = 9 in and therefore, the equation for the table is:

\(\displaystyle{h = 9n}\)

Al estudiante le falta caminar \(\frac{1}{3}\) de kilómetro.

Step-by-step explanation:

Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio. Dos tercios equivale a la fracción \(\frac{2}{3}\) .

El estudiante avanza medio kilómetro en bus. Un medio equivale a la fracción \(\frac{1}{2}\), por lo tanto un medio es la mitad de una cantidad.  Para calcular la distancia recorrida en bus se realiza la siguiente multiplicación:

\(\frac{1}{2} *\frac{2}{3}\)

Resolviendo:

\(\frac{1}{2} *\frac{2}{3} =\frac{1*2}{2*3} =\frac{2}{6} =\frac{1}{3}\)

Entonces, la distancia recorrida en bus es \(\frac{1}{3}\) de kilómetro.

Para calcular la distancia recorrida a pie se calcula la diferencia entre la distancia total a recorrer por el estudiante y la distancia recorrida en bus. Esto es:

\(\frac{2}{3} - \frac{1}{3}\)

Resolviendo:

\(\frac{2}{3} - \frac{1}{3}=\frac{2-1}{3} =\frac{1}{3}\)

Al estudiante le falta caminar \(\frac{1}{3}\) de kilómetro.

C. Quadratic model

Step-by-step explanation:

Determine what type of model best fits the given situation: Farmer Joe has 1,000 bushels of corn to sell. Presently the market price for corn is $5.00 a bushel. He expects the market price to increase by $0.15 per week. For each week he waits to sell, he loses ten bushels due to spoilage. A. none of these B. exponential C. quadratic D. linear

Given:

The quantity of corn Farmer Joe has to sell = 1,000 bushels

The present market price for corn = $5.00 a bushel

The amount by which he expects the market price to rise per week =$0.15

The number of bushels lost to spoilage per week = 10

The price of the corn per bushel with time = 5 + 0.15×t

The amount of corn left with time= 1000 - 10×t

Where;

t = Time in minutes

Value of the corn = Amount of corn left × Price of corn

Value of the corn = (1000 - 10×t) × (5 + 0.15×t)

=(1000-10t) × (5+0.15t)

=5,000 + 150t - 50t - 1.5t²

= -1.5t² +100t + 5000

Value of the corn= -1.5t² +100t + 5000.
