A 4-cylinder engine has a bore of 3 inches and a stroke of 3 inches. What’s the total piston displacement

Answers

Answer 1

Answer:

Piston displacement = 84.8

Step-by-step explanation:

We will find the volume of the cylinder in order to find the piston displacement.

Here, (bore = diameter, so r = diameter/2) (height = stroke)

Volume = [tex] \pi r^2h[/tex] [tex]=3.14\times1.5^2\times 3[/tex] = 21.2 cubic units

Since the engine has 4 cylinders, so we will multiply the piston displacement by 4 to get:

Piston displacement = [tex]21.2 \times 4[/tex] = 84.8

Answer 2
Final answer:

The total piston displacement for a 4-cylinder engine with a bore and stroke of 3 inches can be calculated using the formula: pi/4 * bore^2 * stroke * number of cylinders. For this example, it is approximately 113.097 cubic inches.

Explanation:

To calculate the total piston displacement, we use the formula for the displacement of a single cylinder, which is pi/4 * bore^2 * stroke * number of cylinders.

In this scenario, the bore and stroke are both 3 inches and it's a 4-cylinder engine. Therefore, we plug in these values into the formula.

So, the total displacement is pi/4 * (3inch)^2 * 3inch * 4. This calculates to approximately 113.097 cubic inches.

There is a pie eating contest with 9participants. There are 46 pies that are all eaten. Which of the following best describes how many pies each person ate if they are very evenly matched?​

Answers

To determine the average number of pies eaten by each participant in a contest with 9 participants and 46 pies, divide the total pies by the total participants. The result is approximately 5.11 pies per person, indicating they ate very evenly with most having eaten about 5 pies.

The question asks us to find out how many pies each person ate in a pie eating contest with 9 participants and 46 pies consumed. To calculate this, we divide the total number of pies by the number of participants. Here's the calculation:

Divide 46 pies by 9 participants to get the average number of pies per person.

The result is approximately 5.11 pies per person.

Since we can't have a fraction of a pie eaten in a real context, it suggests that participants ate either 5 or 6 pies each, if they are very evenly matched.

Therefore, the best description of how many pies each person ate, assuming they are very evenly matched, would be approximately 5 pies per person, with some participants possibly having eaten 6 pies to account for the total of 46 pies.

Answers

Answer:

41.04 meters

Step-by-step explanation:

The questions which involve calculating the angles and the sides of a triangle either require the sine rule or the cosine rule. In this question, the two sides that are given are adjacent to each other the given angle is the included angle. The initial position is given by A. The tree is denoted as C and the fence post is denoted as B. Since the use of sine rule will complicate the question, it will be easier to solve this question using the cosine rule. Therefore, cosine rule will be used to calculate the length of BC. The cosine rule is:

BC^2 = AB^2 + AC^2 - 2*AB*AC*cos(BAC).

The question specifies that AC = 70 meters, BAC = 25°, and AB = 35 meters. Plugging in the values:

BC^2 = 35^2 + 70^2 - 2(35)(70)*cos(25°).

Simplifying gives:

BC^2 = 1684.091844.

Taking square root on the both sides gives BC = 41.04 meters (rounded to two decimal places).

Therefore, the distance between the point on the tree to the point on the fence post is 41.04 meters!!!

What is the solution to the system of linear equations?

(–1.7, –2.8)
(0, –7)
(3, 0.5)

Answers

The solution to the system of linear equations is (3, 0.5).

To solve the system of linear equations by graphing, we'll plot the two equations on the same set of axes and find the point of intersection, which represents the solution.

Start with the first equation, y = -x - 7. Choose a few x-values, calculate the corresponding y-values, and plot the points on the graph.For the second equation, x + 2y = 4, rewrite it in slope-intercept form (y = mx + b) by solving for y: 2y = -x + 4 → y = -0.5x + 2. Plot points using this equation.The point where the two graphs intersect is the solution. Confirm that the coordinates of this point satisfy both equations.

The solution is (3, 0.5). Confirming for the first equation: y = -3 - 7 = -10 and for the second equation: 3 + 2(0.5) = 4. The coordinates match both equations.

The coordinates of △ABC are A(−11,7), B(−5,−3), C(−2,3). After a dilation, the coordinates are A'(22,−14), B'(10,6), C'(4,−6). Find the scale factor.

Answers

Answer:

Step-by-step explanation:

Before a dilation you have the point (x,y).

After a dilation of a scale factor of r you have (r*x,r*y).

Let's look at one pair of corresponding points.

A(-11,7)  and A'(22,-14)

We need to figure out what we can multiply to -11 to get 22.

We need to figure out what we can multiply to 7 to get -14.

Hopefully it is the same number or this isn't a dilation.

So to get from pre-image to image you need to multiply by -2 because -11*-2=22 and 7*-2=-14.

The scale factor is -2.

The dilation is this: (x,y)->(-2x,-2y)

The required scale factor is -2

What is scale factor?

The scale factor is a measure for similar figures, who look the same but have different scales or measures.

How to find the scale factor? We know that if  we have the point (x, y) before a   dilation     and  (ax, ay) after a dilation, then a is the scale factor

Let's consider one pair of corresponding points.

A(-11,7)  and A'(22,-14)To get the scale factor we need to find out what we can multiply to -11 and 7 to get 22 and -14

Clearly we need to multiply by -2.

This is applicable for all the points

So, the scale factor is -2.

the scale of a map is 1:500000 the actual distance between two town is 172 km calculate the distance, in centimeters, between two towns on the map. ​

Answers

Answer:

34.4 cm

Step-by-step explanation:

The scale of the map is 1:500000

This means 1 cm in the map is equivalent to 500000 cm in actual.

So, first we need to convert the distance between the 2 towns in centimeters.

The distance between two towns is 172 km

172 km = 172 x 1000 meters = 172,000 meters

172,000 meters = 172,000 x 100 cm = 17,200,000 cm

500,000 cm in actual on the map = 1 cm

1 cm in actual on the map = [tex]\frac{1}{500000}[/tex] cm

17,200,000 cm in actual on the map will be = [tex]\frac{1}{500000} \times 17200000 = 34.4[/tex] cm

Thus, 172 km actual distance would be represented by 34.4 cm on the map

The distance between two towns on a map, with a scale of 1:500000 is 34.4 cm.

The question asks us to calculate the distance, in centimeters, between two towns on a map given the scale of the map is 1:500000, and the actual distance between the two towns is 172 km. First, we convert the actual distance from kilometers to centimeters by multiplying 172 km by 100,000 (since 1 km = 100,000 cm). This gives us 17,200,000 cm. Then, we use the map's scale to find the map distance. The scale 1:500000 means that 1 cm on the map equals 500000 cm in the real world. Therefore, we divide the real-world distance in centimeters by the scale factor (17,200,000 cm / 500000 = 34.4 cm). Thus, the distance between the two towns on the map is 34.4 cm.

How many multiples of three are between 10 and 787 and show work pls

Answers

787-10=777
777/3=259

259 multiples of 3

As per the concept of arithmetic sequence, there are 259 multiples of three between 10 and 787

To solve this problem, we need to find the first and last multiples of three within the given range and then count how many integers are there in between

Step 1: Find the first multiple of three greater than or equal to 10.

The first multiple of three greater than or equal to 10 is 12.

Step 2: Find the last multiple of three that is less than or equal to 787.

The largest multiple of three less than or equal to 787 can be calculated as follows:

Divide 787 by 3:

787 ÷ 3 ≈ 262.33

The largest multiple of three less than or equal to 787 is:

262 × 3 = 786

Step 3: Count the multiples of three within the range.

Now that we have found the first and last multiples of three within the range, we need to count the number of multiples of three between them, including the endpoints.

The multiples of three between 12 and 786 are:

12, 15, 18, ..., 783, 786.

Step 4: Calculate the total count of multiples.

To calculate the total count, we can use the formula for finding the number of terms in an arithmetic sequence:

Number of terms = (last term - first term) / common difference + 1.

In this case, the first term is 12, the last term is 786, and the common difference (the difference between consecutive terms) is 3.

Number of terms = (786 - 12) / 3 + 1

Number of terms = 774 / 3 + 1

Number of terms = 258 + 1

Number of terms = 259.

Answers

Answer:

the probability is the event is certain to happen

Step-by-step explanation:

Answer:

This event is certain to happen.

The probability is 1.

Step-by-step explanation:

Probability theory aims to explain the chance of an event occurring. In this case, there are 3 yellow balls, 4 blue balls and 8 red balls. The total of balls will be 3 + 4 + 8 = 15

If a random ball is removed, it can be any of three colors. The color that has the most balls will have a higher chance of being chosen from the 15 totals.

Likelihood of drawing a red ball: 8/15

Probability of a yellow ball: 3/15

Blue ball probability: 4/15

The question explains that only one ball will be removed and explains that there are only 3 colors. Therefore, when removing a ball, it will certainly be one of three colors.

This can be confirmed by adding the probability of each ball: 8/15 + 3/15 + 4/15 = 15/15 = 1

Thus, if a primary ball is removed, it will certainly be one of three colors. Moreover we can say that chance of being red is greater than being blue, which is greater than being yellow.

Why is this the graph of the function f(x)=4x^2-8x+7?

Answers

Answer:

I'll be referring to this form: ax^2-bx+c

The 4x^2 is the rate that it goes up. If a is greater than 1, then that means the graph gets narrower from the parent function x^2. You can clearly see that in that graph.

The c is always the y-intercept. In this case, you can see that it's 7. The graph clearly shows 7 as it's y-intercept as well, so that matches well.

Sadly, I do not know how to compare the 8x into this situation without a calculator, but that information should be quite enough to see how that function is in that graph.

     = [tex]\sqrt{12^2+(-11)^2}[/tex]

     = [tex]\sqrt{144+121}[/tex]

     = [tex]\sqrt{265}[/tex] ≈ 16.3 ( to 1 dec. place )

Answers

Answer:

The correct option is C

Step-by-step explanation:

The given expression is:

=y²+7y+12/y²-3y-18

Break the middle term of both the numerator and denominator:

=y²+4y+3y+12/y²-6y+3y-18

Take the common from the expressions:

=y(y+4)+3(y+4)/y(y-6)+3(y-6)

=(y+3)(y+4)/(y+3)(y-6)

The same terms will be cancelled: Then we have,

=(y+4)/(y-6)

Therefore the correct option is C....
