Darcy harvest 8 3/4 acres of corn every 5/6 of an hour. How many acres per hour?

Answer:

x = 127

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6, thus

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720 for x

120 + 100 + 128 + 133 + 112 + x = 720, that is

593 + x = 720 ( subtract 593 from both sides )

x = 127

To find the scale factor, compare the corresponding dimensions of the two shapes. Divide the dimension of shape A by the corresponding dimension of shape B to calculate the scale factor.

In order to find the scale factor applied to shape B to make shape A, we need to compare the corresponding dimensions of the two shapes. The scale factor is determined by dividing the dimension of shape A by the corresponding dimension of shape B. In this case, we compare the lengths of the shapes, so the scale factor is determined by dividing the length of shape A by the length of shape B.

Let's calculate the scale factor:

Therefore, the scale factor is 2/3 for all dimensions of shape B to make shape A.

∠AOC

Step-by-step explanation:

The statement "A to O to C" is talking about each of the points that form an angle. Each point is given a letter as its name.

The symbol ∠ means angle.

You need two lines to form an angle, and you need two points to form a line. By reusing one of the points, you need three points to form an angle. The point that is being reused is always the point in the middle, in this case, that point is called 'O'.

Answer:

59

Step-by-step explanation:

The three interior angles in a triangle will always add up to 180°, so:

180-93-28=59

The measure of the third angle is 59 degrees.

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

Given are two angles of a triangle.

First angle = 28 degrees

Second angle = 93 degrees

We know that, the sum of the all the three interior angles of a triangle is 180 degrees.

Let x be the measure of third angle.

x + 28 + 93 = 180

x + 121 = 180

Subtracting 121 from both sides,

x = 180 - 121 = 59 degrees

Hence the third angle is 59 degrees.

The distributed form of -2(x-3)^2 is -2x^2 + 12x - 18.

Step-by-step explanation:

The given question is -2(x-3)^2

step 1 :The formula for (a-b)^2 = a^2 - 2ab + b^2

step 2 :Here, the term (x-3)^2 = x^2 - (2*3x) + 3^2

                                                  = x^2 - 6x + 9

step 3 :The expanded form = -2 (x^2 - 6x + 9)

step 4 : where -2 can be distributed to each term inside the bracket.

Therefore, -2(x^2 - 6x + 9) = -2x^2 + 12x - 18

225 employees work as instructors.

Step-by-step explanation:

You want to find what 75% OF 300 is, therefore multiplication will be required in this problem. First you want to convert 75% to a decimal which you could do by just bringing the decimal point to the left twice. which will give you the decimal 0.75.

Now multiply. 0.75*300=225. There are 225 employees that work as instructors.

Final answer:

To find out how many employees work as instructors at Bright Mind Learning, multiply 75% by the total number of employees. 225 of the 300 employees at Bright Mind Learning work as instructors.

Explanation:

To find out how many employees work as instructors at Bright Mind Learning, we need to calculate 75% of the total number of employees. First, convert 75% to a decimal by dividing it by 100: 75/100 = 0.75. Then, multiply this decimal by the total number of employees (300): 0.75 * 300 = 225.

So, 225 of the 300 employees at Bright Mind Learning work as instructors.

The weakest correlation is indicated by a correlation coefficient that is close to 0. This shows that there is little to no predictable relationship between the two variables.

The data set with the weakest correlation will have a correlation coefficient value closest to zero. The correlation coefficient is a measure of the relationship between two variables. Its value ranges from -1 to 1. A value of -1 indicates a perfect negative correlation, a value of 1 indicates a perfect positive correlation, and a value of 0 indicates no correlation. The direction of the correlation is indicated by whether the value is positive or negative, whereas the strength of the correlation is indicated by how close the value is to -1 or 1.

For example, consider two variables, hours of sleep and performance on a test. If the correlation coefficient is close to 1, this suggests that as one variable increases (hours of sleep), the other variable (test performance) also increases. This would be a strong positive correlation. But if the correlation coefficient is close to 0, there is a weak or no correlation, meaning the variables (for example, shoe size and hours of sleep) do not move together in a predictable way.

The y intercept of a graph containing the two points (3,1) and (7,-2) is [tex]\frac{13}{4}[/tex]

Solution:

Given points are (3, 1) and (7, -2)

The equation of line in slope intercept form is given as:

y = mx + c ------- eqn 1

Where, "m" is the slope of line and "c" is the y intercept

Let us first find the slope of line

The slope of line is given as:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here the points are (3, 1) and (7, -2)

[tex](x_1, y_1) = (3, 1)\\\\(x_2, y_2) = (7, -2)[/tex]

Substituting in formula, we get

[tex]m = \frac{-2-1}{7-3}\\\\m = \frac{-3}{4}[/tex]

To find the y intercept:

[tex]\text{Substitute } m = \frac{-3}{4} \text{ and } (x, y) = (3, 1) \text{ in eqn 1 }[/tex]

[tex]1 = \frac{-3}{4} \times 3 + c\\\\1 = \frac{-9}{4} + c\\\\ \text{Simplify the above equation } \\\\1 = \frac{-9+4c}{4}\\\\4 = -9 + 4c\\\\13 = 4c\\\\\text{Divide both sides by 4 }\\\\c = \frac{13}{4}[/tex]

Answer:

Step-by-step explanation:

No. Of quarters n(Q)= 3

No. Of dimes n(D) = 5

No. Of nickels n(N) = 2

Total T = 3+5+2 = 10

Prob(D) = n(D)/T = 5/10 = 1/2

Now there are 9 left since it is not replaced back

Prob(Q) = 3/9 = 1/3

Prob(D and Q) = 1/2 × 1/3 = 1/6

The probability you will pick a dime and then a quarter without putting the dime back in your pocket is 1/6

Probability is the likelihood or chance that an event will occur

If you have 3 quarters, 5 dimes, and 2 nickels in your pocket, the total coins you have will be:

Total outcome = 3 + 5 + 2

Total outcome = 10

Probability of picking a dime = 5/10 = 1/2
Probability of picking a quarter = 3/9 = 1/3

Pr( a dime and then a quarter without putting the dime back in your pocket) = 1/2 * 1/3 = 1/6

Hence the probability you will pick a dime and then a quarter without putting the dime back in your pocket is 1/6

Final answer:

The probability of picking a 1 and then a 12 from a deck of cards numbered 1-12 with replacement is 1/144, since each event is independent and each card has an equal chance of being selected.

Explanation:

The student asked about the probability of selecting a 1 and then a 12 from a deck of cards numbered 1-12, with replacement in between the picks. To find this, we need to consider the events independently, since the card is replaced after the first draw, meaning the probability of the second draw is unaffected by the first.

The formula to calculate the probability of independent events is P(A and B) = P(A) × P(B), where P(A) is the probability of the first event and P(B) is the probability of the second event occurring. Since each card has an equal chance of being picked from the deck, and there are 12 cards in total, the probability of picking any specific card, like a 1 or a 12, is 1/12.

Therefore, the probability of picking a 1 first and then a 12 is P(1 and then 12) = P(1) × P(12), which is equal to (1/12) × (1/12) = 1/144. So, the final probability is 1/144, or about 0.00694.

If n = the numerator and d = the denominator, which of the following systems of equations could be used to solve the problem?

5n = 3d and n - 2 = 2d - 4

5n = 3d and 2n - 4 = d - 2

3n = 5d and 2n - 4 = d - 2

Answer:

5n = 3d and 2n – 4 = d – 2

Solution:

Let n be the numerator of the fraction and d be the denominator of the fraction.

Given the numerator and denominator of a fraction are in the ratio of 3 to 5.

This can be written as n : d = 3 : 5.

⇒ [tex]\frac{n}{d}= \frac{3}{5}[/tex] – – – – (1)

The first few odd counting numbers are:

1, 3, 5, 7, 9, 11, 13, ...

Step 2: Determine the Formula for the Sum

The sum of the first n odd counting numbers can be calculated using the formula:

Sum = n²

This means that the sum of the first n consecutive odd numbers is equal to the square of n.

Step 3: Apply the Formula to Our Problem

In this case, we want to find the sum of the first 1000 odd numbers. Therefore, we set n to 1000:

Sum = 1000²

The Cindy's new rent be if she includes the renters insurance is $836.08

We are given that;

An annual premium = $565.00

Now,

To find Cindy's new rent, we need to add the monthly payment for the renters insurance to her current rent.

To find the monthly payment for the insurance, we need to divide the annual premium by 12, since there are 12 months in a year. We get:

565 / 12 = 47.08

So, the monthly payment for the insurance is $47.08.

Adding this to Cindy's current rent, we get:

789 + 47.08 = 836.08

Therefore, by unitary method the answer will be $836.08.

Answer:

[tex]4(x+3.5)^{2}=0[/tex]

Step-by-step explanation:

we have

[tex]4x^{2}+28x+49=0[/tex]

step 1

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex](4x^{2}+28x)=-49[/tex]

step 2

Factor the leading coefficient

[tex]4(x^{2}+7x)=-49[/tex]

step 3

Complete the square. Remember to balance the equation by adding the same constants to each side

[tex]4(x^{2}+7x+3.5^2)=-49+(3.5^2)(4)[/tex]

[tex]4(x^{2}+7x+12.25)=0[/tex]

step 4

Rewrite as perfect squares

[tex]4(x+3.5)^{2}=0[/tex]

The equation by completing the square is [tex]\[ (x + \frac{7}{2})^2 = 0 \].[/tex]

To complete the square for the quadratic equation [tex]\(4x^2 + 28x + 49 = 0\)[/tex], we need to follow these steps:

Divide the entire equation by the coefficient of [tex]\(x^2\)[/tex] to make it equal to 1. This gives us:

[tex]\[ x^2 + 7x + \frac{49}{4} = 0 \][/tex]

Next, we need to find the value to complete the square. This is done by taking half of the coefficient of [tex]\(x\)[/tex], which is [tex]\(\frac{7}{2}\)[/tex], and squaring it:

[tex]\[ \left(\frac{7}{2}\right)^2 = \frac{49}{4} \][/tex]

We add and subtract this value to the equation to complete the square:

[tex]\[ x^2 + 7x + \frac{49}{4} - \frac{49}{4} + \frac{49}{4} = 0 \][/tex]

Now, we can rewrite the equation as a perfect square trinomial and a constant:

[tex]\[ (x + \frac{7}{2})^2 - \frac{49}{4} + \frac{49}{4} = 0 \][/tex]

Simplify the equation by combining the constants:

[tex]\[ (x + \frac{7}{2})^2 = 0 \][/tex]

Step-by-step explanation:

If point J is the midpoint of segment FG with endpoints F(1,4) and G(5,12), then its coordinates are

[tex]x_J=\dfrac{x_F+x_G}{2}=\dfrac{1+5}{2}=3\\ \\y_J=\dfrac{y_F+y_G}{2}=\dfrac{4+12}{2}=8[/tex]

If point K is the midpoint of segment GH with endpoints G(5,12) and H(-1,4), then its coordinates are

[tex]x_K=\dfrac{x_G+x_H}{2}=\dfrac{5+(-1)}{2}=2\\ \\y_K=\dfrac{y_G+y_H}{2}=\dfrac{12+4}{2}=8[/tex]

The measure of JK is

[tex]JK=\sqrt{(3-2)^2+(8-8)^2}=\sqrt{1^2+0^2}=1\ unit[/tex]

Given the coordinates of their endpoints, you find that the points of interest, J and K, have coordinates J(3,8) and K(2,8), respectively. You can then apply the distance formula to find the distance between these two points, resulting in 1.

To find the distance between two points, we can apply the distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2).

Given that J is the midpoint of FG, the coordinates of J can be found using the midpoint formula ((x1 + x2) / 2, (y1 + y2) / 2). By applying this formula, we find that J = ((1 + 5) / 2, (4 + 12) / 2) = (3,8).

Similarly, the coordinates of K, as the midpoint of GH, are K = ((5 + (-1)) / 2, (12 + 4) / 2) = (2,8).

Now we can plug the coordinates of J and K into the distance formula to find JK: d = sqrt((x2 - x1)^2 + (y2 - y1)^2) = sqrt((2 - 3)^2 + (8 - 8)^2) = sqrt((1)^2 + 0) = sqrt(1) = 1.

Answer:

The volume of required foam is 0.1 cm³  

Step-by-step explanation:

Given as :

The volume of box = v = 113.14 cm³

The radius of the crystal ball = r = 3 cm

Let The volume of required foam = V cm³

According to question

Volume of  crystal ball = [tex]\dfrac{4}{3}[/tex] × π × radius³                        where π = 3.14

i.e Volume of ball = [tex]\dfrac{4}{3}[/tex] × π × 3³

Or, Volume of ball = [tex]\dfrac{4}{3}[/tex] × π × 27

Or, Volume of ball = [tex]\dfrac{4}{3}[/tex] × 3.14 × 27

Or, Volume of ball = 4 × 3.14 × 9

Or, Volume of ball = 113.04 cm³

Again

∵ volume of crystal ball = v' = 113.04 cm³

So ,  The volume of required foam = volume of box - volume of crystal ball

Or, V =  v - v'

Or, V = 113.14 cm³ -  113.04 cm³

∴   V = 0.1 cm³

So, The volume of required foam = V = 0.1 cm³

Hence, The volume of required foam is 0.1 cm³  . Answer
