find the circumference use 3.14 for pie r=2 m

Answer:

1. 90      2. 130       3. 55

Step-by-step explanation:

Every triangle when you add all the angles will = 180 degrees for this you add the 2 angles that you have and subtract it from 180

1.   35+55+ C = 180

90 = 180

C = 90

2. 25+25+C = 180

50 + C = 180

C = 130

3. 62 + 63 + C = 180

125 + C = 180

C = 55

Answer:

Step-by-step explanation:

sum of all the angles of triangle = 180

1) ∠1 + ∠2 + ∠3 = 180

35 + 55 + ∠3 = 180

90 + ∠3 = 180

       ∠3 = 180 -90

            ∠3 = 90

If one angle is 90, then, it is a right angled triangle.

2) 25 + 25+ ∠3 =180

        50 + ∠3 =180

             ∠3 =180 -50

       ∠3 = 130

If two angles are equal, then it is an isosceles triangle.

3) 62 + 63 + ∠3 =180

             125 +∠3=180

                     ∠3 = 180-125

                     ∠3 = 55

All the angles are different, so it is a scalene triangle

On solving the system of linear equations y = -x + 2 and 3x - y = 6, the point of solution is obtained as option 3: (2,0).

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The system of linear equations are -

y = -x + 2....(1)

3x - y = 6....(2)

Writing equation (2) in standard form y = mx + b -

- y = -3x + 6....(3)

Now solving the equation (1) and (3) by adding -

y + (-y) = -x + 2 + (-3x + 6)

0 = -4x + 8

4x = 8

x = 2

Now, substituting the value of x = 2 in equation (1) -

y = -x + 2

y = -(2) + 2

y = -2 + 2

y = 0

Therefore, the values for x and y are 0 and 2 respectively.

Answer:

l = 194999.45

Step-by-step explanation:

I'm going to assume that you meant 3.14 by 3,14.

336,765 = 3.14 × 0.55 × (l + 0.55)

336,765 ÷ (3.14 × 0.55) = l + 0.55

(336,765 ÷ (3.14 × 0.55)) - 0.55 = l

l = 194999.45

Step-by-step explanation:

1. 9x4/5= 7.2<9

2. 4x6/5= 4.8>4

The constant of proportionality is 1 point for every 10 minutes of play.

The equation that represents the relationship is:

Points = (Time played in minutes) / 10

The number of points awarded for 12 minutes of play is 1.2 points.

Part A: Scenario 1: For every 2 minutes of play, the game awards 1/2 point.

Scenario 2: For every 15 minutes of play, the game awards 1 1/4 points.

Scenario 1: 2 minutes → 1/2 point

Scenario 2: 15 minutes → 1 1/4 points (which is equal to 5/4 points)

2 minutes / 1/2 point = 15 minutes / 5/4 points

(2 minutes / 2) / (1/2 point) = (15 minutes / 2) / (5/4 points)

1 minute / (1/2 point) = 7.5 minutes / (5/4 points)

1 minute * (2/1 point) = 7.5 minutes * (4/5 points)

2 minutes / point = 30 minutes / 5 points

Finally, let's simplify the equation by multiplying both sides by 5:

10 minutes / point = 30 minutes / 1 point

From this equation, we can see that the constant of proportionality is 1 point for every 10 minutes of play.

Part B: The equation that represents the relationship is:

Points = (Time played in minutes) / 10

Part C: To graph the relationship, we'll plot points on the y-axis and time played in minutes on the x-axis. The points awarded increase linearly with time, and for every 10 minutes played, the player receives 1 point. Therefore, the graph will be a straight line with a positive slope of 1/10. The y-intercept will be at (0, 0) since no points are awarded for 0 minutes played.

Part D: To find the number of points awarded for 12 minutes of play, we'll use the equation from Part B:

Points = (Time played in minutes) / 10

Substituting the value of 12 minutes:

Points = 12 / 10 = 1.2 points

So, 1.2 points are awarded for 12 minutes of play.

All correct proportions include the following:

A. \(\frac{AC}{CE} =\frac{BD}{DF}\)

D. \(\frac{CE}{DF} =\frac{AE}{BF}\)

In Mathematics and Geometry, two geometric figures are said to be similar when the ratio of their corresponding side lengths are equal and their corresponding angles are congruent.

Hence, the lengths of the pairs of corresponding sides or corresponding side lengths are proportional to one another when two (2) geometric figures are similar.

Since line segment AB is parallel to line segment CD and parallel to line segment EF, we can logically deduce that they are congruent because they can undergo rigid motions. Therefore, we have the following proportional side lengths;

Step-by-step explanation:

The answer is D. None of the above, the long-term DPMO is 25137, which is equivalent to a Z-value of 3.46. The short-term Z-value is usually 1.5 to 2 times the long-term Z-value,

so it would be between 5.19 and 6.92. However, these values are not listed as answer choices. The Z-value is a measure of how many standard deviations a particular point is away from the mean. In the case of DPMO, the mean is 6686. So, a Z-value of 3.46 means that the long-term defect rate is 3.46 standard deviations away from the mean.

The short-term Z-value is usually 1.5 to 2 times the long-term Z-value. This is because the short-term process is more variable than the long-term process. So, the short-term Z-value would be between 5.19 and 6.92.

However, none of these values are listed as answer choices. Therefore, the correct answer is D. None of the above.

after reversing the order of integration, the integral ∫∫[R] 13e²(2x) dx dy evaluates to (117/2)e²6 - (39/4).

To evaluate the integral ∫∫[R] 13e²(2x) dx dy, where R is the region defined by 0 ≤ x ≤ 3 and 0 ≤ y ≤ 3x, we can reverse the order of integration.

The original integral can be rewritten as:

∫[0 to 3] ∫[0 to 3x] 13e²(2x) dy dx

Now we will reverse the order of integration:

∫[0 to 3] ∫[0 to 3x] 13e²(2x) dy dx

The inner integral with respect to y becomes:

∫[0 to 3] [13e²(2x) × y] evaluated from 0 to 3x dx

Simplifying the inner integral:

∫[0 to 3] 13e²(2x) × (3x - 0) dx

∫[0 to 3] 39xe²(2x) dx

To evaluate this integral, we can use integration by parts. Let u = x and dv = 39e²(2x) dx.

Differentiating u with respect to x gives du = dx and integrating dv gives v = (39/2)e²(2x).

Using the formula for integration by parts:

∫ u dv = uv - ∫ v du

we can rewrite the integral:

∫[0 to 3] 39xe²(2x) dx = [(39/2)x × e²(2x)] evaluated from 0 to 3 - ∫[0 to 3] (39/2)e²(2x) dx

Evaluating the limits of the first term:

[(39/2)(3) × e²(2(3))] - [(39/2)(0) × e²(2(0))] - ∫[0 to 3] (39/2)e²(2x) dx

Simplifying:

(117/2)e²6 - 0 - ∫[0 to 3] (39/2)e²(2x) dx

Now we evaluate the remaining integral:

∫[0 to 3] (39/2)e²(2x) dx = [(39/4)e²(2x)] evaluated from 0 to 3

[(39/4)e²(2(3))] - [(39/4)e²(2(0))]

Simplifying:

(39/4)e²6 - (39/4)

Therefore, after reversing the order of integration, the integral ∫∫[R] 13e²(2x) dx dy evaluates to (117/2)e²6 - (39/4).

None of the statements about quantitative versus qualitative research are true.

This is because the comparison between quantitative and qualitative research is not a matter of one being objectively better or more subjective, richer, or more time-consuming than the other. They are different approaches to research, each with its strengths and limitations, and the choice between them depends on the research question, the nature of the data, and the research design.

Quantitative research is characterized by the collection of numerical data that can be analyzed using statistical methods to identify patterns, relationships, and trends. This approach is used when the research question requires an objective measurement of variables that can be quantified and compared across groups. For example, a quantitative study may examine the relationship between height and weight in a population, using statistical techniques to identify the strength of the relationship and its significance.

In an arithmetic series where the first term is 1 and the nth term is 3, the task is to determine the value of n. By using the formula for the nth term of an arithmetic sequence and solving the equation, it is found that n equals 2 in this case.

The value of n in the arithmetic series, we can use the formula for the nth term of an arithmetic sequence, which is given by a_n = a_1 + (n - 1)d, where a_n represents the nth term, a_1 is the first term, n is the number of terms, and d is the common difference.

In this case, a_1 = 1 and a_n = 3. We need to find the value of n.

Using the formula, we can rewrite it as 3 = 1 + (n - 1)d.

Since we know that the common difference is constant in an arithmetic series, we can subtract 1 from both sides to get 2 = (n - 1)d.

Now, we have a_1 = 1 and a_n = 3. By substituting these values into the formula, we can write it as 3 = 1 + (n - 1)(a_n - a_1).

Substituting the known values, we get 3 = 1 + (n - 1)(3 - 1).

Simplifying further, we have 3 = 1 + 2(n - 1).

Expanding the expression, we get 3 = 1 + 2n - 2.

Combining like terms, we have 3 = 2n - 1.

Adding 1 to both sides, we get 4 = 2n.

Dividing both sides by 2, we find n = 2.

Therefore, the value of n in the given arithmetic series is 2.
