De acuerdo con el ciclo práctico o ciclo real de funcionamiento de un motor, las válvulas de admisión y escape no se abren y cierran exactamente en los puntos muertos superior e inferior. Debido a esto se genera un instante donde están abiertas las válvula de admisión y de escape al mismo tiempo, a lo que se le conoce como traslape o cruce valvular - ¿Cómo se determina el traslape?

Answer:

[tex]mean = \frac{ \sum \: xf}{n} \\ \frac{(27 \times 2) + (28 \times 4) + (29 \times 3) + (31 \times 5) + (33 \times 6)}{(2 + 4 + 3 + 5 + 6)} [/tex]

Answer: -27/64

Step-by-step explanation:

flip to multiply by the reciprocal.

becomes:  (-3/8) · 9/8

a negative · a positive makes a negative.

multiply normally, add the negative sign after.

9 · 3 = 27

8 · 8 = 64

new fraction: 27/64 (cannot be simplified form here)

add negative sign.

final: -27/64

Answer:

[tex] \frac{3x + 1}{2} - 1 = 2x) \times 2 \\ 3x + 1 - 2 = 2x \\ 3x - 2x = 2 - 1 \\ x = 1 [/tex]

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

[tex]\frac{3x+1}{2}-1=x[/tex]

Add 1 to both sides:

[tex]\frac{3x+1}{2}-1+1=x+1[/tex]

[tex]\frac{3x+1}{2}=x+1[/tex]

Multiply both sides by 2:

[tex]\frac{3x+1}{2}\times \:2=x\times \:2+1\times \:2[/tex]

[tex]3x+1=x\times \:2+2[/tex]

Subtract 1 from both sides:

[tex]3x+1-1=x\cdot \:2+2-1[/tex]

[tex]3x=2x+1[/tex]

Subtract 2x from both sides:

[tex]3x-2x=2x+1-2x[/tex]

[tex]x=1[/tex]

Answer: Roughly Symmetrical

Step-by-step explanation: There's no super easy way to explain why other than learning with experience but if you look at about the center of the graph, there are two peaks, and each side of the graph if split at about 68 which is the center, has 7 points each. This in conjunction with the shape and relatively normal spread makes it roughly symmetrical, not quire symmetrical but getting there.

Answer:

[tex]y = \frac{1}{5} x - 9[/tex]

Step-by-step explanation:

The slope-intercept form is y = mx + b, where:

m = slope

b = y-intercept.

The slope (m) tells you the steepness of the line. It is the average rate of change which measures how the y-value changes for each one-unit change in the x-value. Hence, slope [tex]= \frac{rise}{run}[/tex].  So the given slope of 1/5 means that for every 1 unit change in the y-value, the x-value changes by 5 units (you go up 1 unit, and "run" 5 units to the right).

Next, the y-intercept is the point on the graph where it crosses the y-axis, and has the coordinates, (0, b). It is also the value of y when x = 0. Since you're given the y-intercept of -9, then that means that it is the y-coordinate of (0, b). So, it becomes (0, -9).

Now that we have our slope (m ) = 1/5, and the y-intercept (b ) = -9, we can write the equation of the line as:

[tex]y = \frac{1}{5} x - 9[/tex]

(I'm also including a screenshot of the line where it shows the y-intercept of (0, -9) on the graph).

FVRF

Step-by-step explanation:

Answer:

no you cant be certain but you can.

Step-by-step explanation:

Answer: (4,9)

Step-by-step explanation: We assume a straight line, so y=mx+b.

We can determine slope, m: Change in x is (6-5)=1. Change in y is (1-(-4)) = 5 Slope is (Change in y)/(Change in x) = 5/1, or 5

y=5x+b

Find b for (6,1)

1 = 5*6 + b

b = -29

y = 5x-29

Since A is (6,1) and m is (5,-4) we can calculate y for x=4 (point B)

y = 5(4)-29

y = -9

B is (4,-9)

Go up to from the current letter to get the answer i think?

You can try finding the pattern behind the conversion.

The code for SHARP is UJCTR

Well it depends. There are infinite possibilities.

Most of the times, if its like a question from some exam or book etc, then there is certain simple pattern which you can see if focus. Otherwise, there may be too complex, or sometimes too simple, or sometimes moderately complex patterns.

For given case, you can see that the pattern is to take the third letter from the given letter from the English alphabet.

For B it was B - C - D, thus, D

For E it was E - F - G, thus, G

For A it was A - B - C, thus, C

For D it was D - E - F, thus, F

Similarly, we get:

For S it was S - T - U, thus, U

For H it was H - I - J, thus, J

For A it was A - B - C, thus, C

For R it was R - S - T, thus, T

For P it was P - Q - R, thus, R

Thus,

Answer:

90 students

Step-by-step explanation:

Let u be 1 unit.

8u = 240

u = 240÷8

= 30

3u = 30×3

= 90

Adding all of the areas together:

5 x 6 = 30

4 x 6 = 24

3 x 6 = 18

4^2 + 3^2 = 16 + 9 = 25(square root) = 5

" " = 5

30 + 24 + 18 + 5 + 5 = 82 ft^2

Answer:

0.45 miles per minute

Step by Step Explanation:

Look at the units:  miles per hour is miles/hour

If we multiply

miles       hour         miles

-----   *     -------  =  ---------

hour       minute      minute

(27 miles/hour)(1/60 hours/minute) = 27/60

= 9/20 = 0.45 miles per minute

Answer:

The answer would be , less than one .

The difference of 1.4 - 0.95 is less than one as per the concept of subtraction.

To determine this, we can simply subtract the two values:

1.4 - 0.95 = 0.45

Since the result of the subtraction is 0.45, which is less than one, we can conclude that the difference of 1.4 - 0.95 is indeed less than one.

In numerical terms, the difference is 0.45, which is 45 hundredths or less than half of one whole unit.

When comparing the two original values, 0.95 is almost half of 1.4, making the difference smaller than one.

In summary, the difference of 1.4 - 0.95 is less than one, specifically 0.45. It is essential to pay attention to the decimal values and their magnitudes when determining the difference between two numbers.
