The equation that represent the whole slices is as follows:

2 / 3 x = 4 .

Therefore, the answer is A.

A pizza was cut into equal slices. Ben ate 4 of the slices.  The amount Ben ate was 2/3 of the whole pizza.

Therefore, the equation that represent a way to find the total number of slices that were in the whole pizza can be calculated as follows:

Let

x = amount of the whole pizza

Therefore,

2 / 3 x = 4

cross multiply

2x = 4(3)

2x = 12

x = 12  /2

x = 6

Therefore, the whole slice is 6.

Hence, the equation is 2 / 3 x = 4

Answer:

18 dollars

Step-by-step explanation:

he is left with 8 dollars. He buys one granola bar (2), one smoothie (3), and one sandwich (5).

This means that he has spent 2 dollars, 3 dollars, and 5 dollars, which totals  10 dollars (2 + 3 + 5 = 10). He is left with 8 dollars, so we know that he originally had 18 dollars because 10 + 8 = 18.

The function to calculate her regular pay rate is y = 55x  + 75.

Her regular pay rate is 12 dollars.

Juliana expects to work overtime this week. She will work 40 hours at her regular pay rate.

She usually work 15 hours at 5 dollars per hour more than her regular rate.

Therefore, the function to calculate how much money she will make base on her regular pay rate is as follows:

let her regular pay rate = x

Therefore,

y = 40x + 15(x + 5)

y = 55x  + 75

Let's find her regular pay rate when she earns 735 dollars(including the overtime)

Therefore,

735 = 40x + 15(x + 5)

735 = 40x + 15x + 75

735 - 75 = 55x

660 = 55x

x = 660 / 55

x = 12

Therefore, her regular pay rate is 12 dollars.

b leg = 5

The formula to find the hypotenuse is [tex]\sqrt{a^{2}+b^{2} } = \sqrt{9^{2} +5^{2} } = \sqrt{81+25} = \sqrt{106} = 10.246\\[/tex]

The required container can hold approximately 1570.8 cubic inches of soil.

By enclosing units in containers—that is, by circling, boxing, or otherwise enclosing units—container numbers indicate magnitude. The worth of each container's contents is multiplied by the number system's fundamental unit. Typically, the basis is either 2 or 10 (the decimal system) (the binary system).

To find the volume of the container, we can use the formula for the volume of a cylinder:

[tex]$$ V = \pi r^2 h $$[/tex]

where r is the radius of the base (half the diameter) and $h$ is the height of the cylinder.

In this case, the diameter of the container is 10 inches, so the radius is half that, or 5 inches. The height is given as 20 inches. Substituting these values into the formula, we get:

[tex]$$ V = \pi (5\text{ in})^2 (20\text{ in}) = \pi (25\text{ in}^2)(20\text{ in}) \approx 1570.8 \text{ in}^3 $$[/tex]

Therefore, the container can hold approximately 1570.8 cubic inches of soil.

Answer:

No, rhombuses are not necessarily rectangles. While both shapes are quadrilaterals with opposite sides parallel, there is an additional requirement for a rectangle that is not present in a rhombus. Specifically, a rectangle must have all interior angles measuring 90 degrees, while a rhombus can have any angle between 0 and 180 degrees.

On the other hand, all rectangles are parallelograms, while not all parallelograms are rectangles. Similarly, all squares are both rhombuses and rectangles, but not all rhombuses or rectangles are squares. In summary, a rhombus is a quadrilateral with four equal sides, while a rectangle is a quadrilateral with four right angles. While there is some overlap between the definitions, they are not equivalent.

Answer:

Rhombuses are not rectangles

Step-by-step explanation:

This is because rhombuses do not have 4 right angles.

A square would be a rectangle because its a quadrilateral with 4 right angles

while a rectangle wouldn't be a square because it doesn't have 4 equal sides

A rhombus is a quadrilateral that has 4 equal sides but doesn't have 4 right angles, making it not a rectangle

Sure! Tidal energy is a type of renewable energy that is harnessed from the movement of ocean tides. There are different approaches to harnessing tidal energy, but the three options given in the question are:

I. Floating platform with turbines: This approach involves anchoring a floating platform in the tidal zone, where the rise and fall of the tides can be used to turn turbines and generate electricity. The turbines are connected to generators, which convert the mechanical energy of the turning turbines into electrical energy. This approach is commonly used in commercial tidal energy projects, such as the MeyGen tidal energy project in Scotland.

II. Floating ship with turning pendulum: This approach, also known as the "pendulor" or "pendulum" system, involves a floating ship or barge that is anchored in the tidal zone. The ship is designed to swing back and forth with the movement of the tides, and this movement is used to turn a pendulum, which in turn drives a generator. The idea behind this approach is that the ship's movement can be used to generate more energy than just the up-and-down motion of a floating platform with turbines. However, this approach is still in the experimental phase and has not yet been deployed on a commercial scale.

III. Having water spin turbines attached to fence: This approach involves installing turbines directly in the flow of tidal currents. The turbines are attached to a fence-like structure, which guides the flow of water and increases the speed of the current as it passes through the turbines. The spinning turbines generate electricity, which is then sent to a generator and converted into usable power. This approach is also known as "barrage" or "fence" technology, and it has been used in a few commercial tidal energy projects, such as the La Rance tidal power plant in France.

So, to answer the question, the correct answer is "I and III" since both involve using turbines to generate electricity from the movement of ocean tides.

Floating platform with turbines and Having water spin turbines attached to fence best  describes an approach used to harness tidal energy.

Energy is the capacity to do work

The approach used to harness tidal energy is described by option I and III.

I. Floating platform with turbines - This involves placing turbines on floating platforms that are anchored to the seabed.

As the tide comes in and out, the water flows through the turbines, generating electricity.

III. Having water spin turbines attached to fence - This involves building a fence-like structure across a tidal inlet.

As the tide comes in and out, the water flows through the fence and spins turbines, generating electricity.

Option II, floating ship with turning pendulum, does not describe an approach used to harness tidal energy.

Therefore, floating platform with turbines and having water spin turbines attached to fence best  describes an approach used to harness tidal energy.

Step-by-step explanation:

sorry that's all i can do..

Answer: 3.5714286e^-10 or 0.00000000035714286 or 3.5714286 × 10^-10

Step-by-step explanation:

First, we divide 0.0001 by 28, which equals 3.5714286e-6.

And since we added 4 zeros to the equation, the negative (e) will be pushed by -4. So, it should look like this: 3.5714286e-10, and the equation is complete.

According to given information the correct answer is [tex]$t =[/tex] [tex]\frac{5}{4}$[/tex] seconds.

An equation is a mathematical statement that asserts the equality of two expressions. It typically consists of two expressions separated by an equals sign (=), with the expression on the left side equal to the expression on the right side. The equals sign indicates that the two expressions have the same value for some or all values of the variables involved.

The equation that gives the height [tex]($S$)[/tex] of the ball at time [tex]($t$)[/tex] is:

[tex]$$S = 140 + 128t - 16t^2$$[/tex]

To find the time [tex]($t$)[/tex] when the ball is at a certain height, we can set the equation equal to that height and solve for [tex]t$.[/tex]

For example, if we want to find the time when the ball is at a height of 200 feet, we would set [tex]$S = 200$[/tex] and solve for [tex]t$:[/tex]

[tex]$$200 = 140 + 128t - 16t^2$$[/tex]

Rearranging and simplifying, we get:

[tex]$$16t^2 - 128t + 60 = 0$$[/tex]

Dividing both sides by 4, we get:

[tex]$$4t^2 - 32t + 15 = 0$$[/tex]

We can solve for [tex]$t$[/tex] using the quadratic formula:

[tex]$$t[/tex]= [tex]\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$[/tex]

where  [tex]a = 4$, $b = -32$,[/tex]  and  [tex]c = 15$.[/tex]

Plugging in these values, we get:

[tex]$$t[/tex] = [tex]\frac{-( -32) \pm \sqrt{(-32)^2 - 4(4)(15)}}{2(4)}$$[/tex]

Simplifying, we get:

[tex]$$t =[/tex] [tex]\frac{32 \pm \sqrt{484}}{8}$$[/tex]

[tex]$$t =[/tex][tex]\frac{32 \pm 22}{8}$$[/tex]

Therefore, the possible values of [tex]$t$[/tex] are:

[tex]$$t =[/tex] [tex]\frac{7}{2} \quad \text{or} \quad t = \frac{5}{4}$$[/tex]

Since the ball is thrown upward, the time when the ball is at a height of 200 feet is the time it reaches the height of 200 feet on its way up, not on its way down.

Therefore, according to given information the correct answer is [tex]$t =[/tex] [tex]\frac{5}{4}$[/tex] seconds.

According to the above, the figure rotated 180° would remain as shown in the image in the fourth quadrant of the Cartesian plane (+ , -)

To rotate the figure 180 degrees we must take into account its initial position. Additionally, we must remember that each quadrant is equivalent to 90°, so we would have to rotate it two quadrants. In this case it is not important to know if it rotates counterclockwise or clockwise because we know it will be in quadrant #4.

In this case, we must be guided by the coordinates that the figure has to draw it again. From the above we can see that it has four coordinates at the top. In the case of the figure rotated in quadrant #4, these four coordinates would be at the bottom because the figure has been rotated 180°.

In response to the query, we can state that The p-value, rounded to four probability decimal places, is 0.0056.

Mathematicians use probability theory to determine the chance that an event will occur or a statement is true. A probability of about 0 reflects how probable an event appears to occur, whereas a risk is a value between 0 and 1, where 1 suggests certainty. Probability is a mathematical representation of the likelihood that a specific event will take place. Other ways to express probabilities are as integers between 0 and 1 or as percentages between 0% and 100%. the ratio of events among equally likely options that lead to a certain event to all other outcomes.
