Answer 1

Answer:

  3.  (x, y) = (20, 30)

  4.  (x, y) = (30, 4)

Step-by-step explanation:

You have equilateral triangles in two different configurations, and you want to find the values marked x and y.

3.

All of the angles marked with an arc are congruent, so all are 60°. The angle marked 80° is an external angle to the top/left triangle. Its value is the sum of the values of the remote interior angles:

  80° = 60° +x°

  20° = x° . . . . . . . subtract 60°

  x = 20

The sides of the equilateral triangle are congruent, so all are length 46. That means the right side is ...

  16 +y = 46

  y = 30 . . . . . . . subtract 16

  (x, y) = (20, 30)

4.

All of the angles marked with an arc are congruent, so all are 60°. The top 60° angle of the equilateral triangle is an external angle to the isosceles triangle at top/right. Its two base angles are the remote interior angles with respect to that 60° exterior angle, so their sum is 60°:

  x° +x° = 60°

  x = 30

The two marked legs of the isosceles triangle are both 20, which means all sides of the equilateral triangle are length 20.

  5y = 20

  y = 4 . . . . . . . divide by 5

  (x, y) = (30, 4)

Find three consecutive odd numbers whose sum is 1899.

Answers

Answer:

631, 633, 635

Step-by-step explanation:

Odd numbers exists in AP with common difference of 2.

That is; 1, 2, 5, 7 etc

So lets say the middle number of the three consecutive numbers is x, the next number to it Will be (x+2), and the previous number will be (x-2)

Therefore, the sequence is (x-2), x, (x+2) ... (1)

and the series will be, (x+

-2) + x + (x+2) = 1899

Solve for x;

x + x + x - 2 + 2 = 1899

3x + 0 = 1899

x = 1899 ÷ 3

x = 633

Therefore the consecutive odd numbers (following 1) is: (633 - 2), 633, (633+2) = 631, 633, 635

Given is that there are two times the amount of milk chocolate bars as there are dark chocolate bars in a box. There are a total of 138 candy bars in the box.

Assume that there are [x] chocolate bars in the box. Then, there will be [2x] milk bars. So, we can write -

2x + x = 138

3x = 138

x = 138/3

x = 46

Therefore, there are 46 chocolate bars and (2 x 46) or 92 milk bars in the candy box.

Answers

The parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3) is a rectangle as two sides are equal, so option A is correct.

What is parallelogram?

A unique kind of quadrilateral created by parallel lines is called a parallelogram. A parallelogram can have any angle between its neighboring sides, but for it to be a parallelogram, its opposite sides must be parallel.

Given data:

The parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3),

Calculate the distance of sides as shown below

[tex]AB = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

AB = [tex]\sqrt{[-7-(-8)]^2 + (8-5)^2}[/tex]

AB =  √(1² + 3²)

AB = √10

Calculate

BC = [tex]\sqrt{[-1-(-7)]^2+(6 - 8)^2}[/tex]

BC = √(36 + 4)

BC = √40 or 2√10

Similarly,

CD = √10

And AD = 2√10

Here AB = CD and BC = AD, opposite sides equal, so it is a rectangle. Therefore, the parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3) is a rectangle as two sides are equal.

Answers

The probability statements after continuity correction are given as follows:

P(x > 118) = P(x > 117.5).P(X < 118) = P(X < 118.5).P(X = 118) = P(117.5 < x < 118.5).

What is continuity correction?

Continuity correction is used as a "correction" when a continuous distribution is used to approximate a discrete distribution. One example of this is the approximation of the binomial distribution to the normal distribution.

Hence, using continuity correction, the range of values that corresponds to a number of exactly x is given as follows:

x - 0.5 < x < x + 0.5.

Thus the range of values of 118 is given as follows:

The linear function that has the greatest initial value is Function C.

Function B has the greatest rate of change.

What is a function?

function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Function A:

The initial value is o.

f(0) = 0

The rate of change.

= (f(4) - f(2)) / 4 - 2

= (10 - 5) / 2

= 5/2

= 2.5

Function B:

The initial value is

y = 3x - 1

y = 3 x 0 - 1 = 0 - 1 = -1

Let y = f(x)

The rate of change.

= (f(2) - f(1)) / (2 - 1)

= (5 - 2) / 1

= 3

Function C:

The initial value is 2.

(0, 2) is considered as when x = 0, y = 2.

Take two coordinates from the graph.

(3, 3) and (6, 4)

The rate of change.

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

For instance, the ratio of half of 10 marbles to half of 50 marbles is 10. When determining if two ratios or fractions are equivalent, the proportion formula is utilized.

2. heads with a coin

3. red or green marble

5. <7 on a 6 sided die.

Step-by-step explanation:

1. The probability of rolling 4 on a 6-sided die is 1/6, as each side is equally probable.

2. The probability of flipping a coin onto heads is 1/2, as there are 2 equally probable outcomes.

3. The probability of drawing red or green out of 6 red, 5 blue, 3 green is 9/14 (9 positive outcomes out of 14).

4. The probability of rolling a 7 with a 6 sided die is 0, as there is no such number on the die.

5. The probability of rolling a number less than 7 on a 6 sided die is 100%, or 1, because any outcome is positive (we can only roll numbers smaller than 7).

The probabilities are:

1. 1/6

Find a solution to the linear equation y=2x+6 by filling in the boxes with a valid value of x and y.

Answers

Answer:

The answer to the linear equation y = 2x + 6 is (x, y) = (1, 2.5). This means that if we plug in x = 1 into the equation, we get y = 2.5.

Step-by-step explanation:

To find the solution to the linear equation y = 2x + 6, we can first rewrite the equation in slope-intercept form. This is done by rearranging the equation to have the form y = mx + b, where m is the slope of the line and b is the y-intercept.

In this case, we have y = 2x + 6. To put this equation in slope-intercept form, we need to isolate the y-term on one side of the equation. We can do this by subtracting 2x from both sides, which gives us y - 2x = 6.

Next, we need to divide both sides of the equation by the coefficient of the y-term, which is -2 in this case. This gives us the equation y = -(1/2)x + 3.

Finally, we can plug in any value of x that we want to find the corresponding value of y. For example, if we plug in x = 1, we get y = -(1/2) * 1 + 3 = 2.5. Therefore, the solution to the equation y = 2x + 6 is (x, y) = (1, 2.5).

In general, if we want to find the solution to a linear equation in slope-intercept form, we can plug in any value of x that we want to find the corresponding value of y. This process is called graphing the line, and it is a useful way to visualize the solutions to linear equations.
