Donna is ordering chocolate chip cookies for her company's picnic. The cookies are sold in packages of 6. She needs 336 cookies. How many packages should Donna buy?

Answer:

The correct answer option is dependent.

Step-by-step explanation:

We are given the following two equations and we are to determine whether these are independent, dependent or inconsistent:

[tex]y = 3x + 6[/tex] --- (1)

[tex]6x - 2y = -12[/tex] --- (2)

To compare these equations with each other, it is a good idea to write them in the same format with y being the subject. So rearranging equation (2) to get:

6x - 2y = -12

6x + 12 = 2y

2y = 6x + 12

y = 3x + 6

A system of equations is said to be dependent when the same line is written in two different forms so that there are infinite solutions.

Hence, this system of equations is dependent having infinite solutions.

The system of equations are classified as independent

To classify the system of equations as independent, dependent, or inconsistent, we can analyze their coefficients.

The given system of equations is:

y = 3x + 6

6x - 2y = -12

Comparing the coefficients, we can see that the slopes of the equations are equal (-2/-6 )

Reduce the fraction to smaller forms, we get;

1/3

Now, since the slopes are different, the system is consistent and has a unique solution, indicating an independent system.

Thus, the equations are independent.

There is only one unique triangle that can be drawn with side lengths of 4cm, 5cm, and 10cm.

A triangle is defined by its side lengths. In order for a triangle to be formed, the sum of any two side lengths must be greater than the third side length. In this case, we have side lengths of 4cm, 5cm, and 10cm. We can check if these lengths can form a triangle by checking the triangle inequality:

Since all three inequalities are true, a triangle can be formed with side lengths of 4cm, 5cm, and 10cm. Therefore, there is only one unique triangle that can be drawn with these side lengths.

Answer:

(x - 5i)(x + 5i)

Step-by-step explanation:

Find the roots by solving x² + 25 = 0

hence x² = - 25 ( take the square root of both sides )

x = ± 5i

x² + 25 = (x - 5i)(x + 5i)

Answer:

The 52nd term is -125

Step-by-step explanation:

The formula for an arithmetic sequence is

an = a1+d(n-1)

where a1 is the first term and d is the common difference.

a1 = 28

d = 25-28 = -3

Let's check  19-22 = -3  so the common difference is correct

an = 28 - 3(n-1)

We want to find the 52 term  so n = 52

a52 = 28 -3 (52-1)

a52 = 28 -3(51)

a52 = 28 -153

a52 = -125

Answer:

1x^2 - 4x is the quotient and remainder is 7

Step-by-step explanation:

Let use synthetic division

First we write all the coefficients of x^3 - 5x^2 + 4x + 7 inside

we need to divide by x-1. x-1=0 so x= 1

so we put 1 outside

The coefficients of x^3 - 5x^2 + 4x + 7  is 1, -5, 4, 7

    1                       1            -5           4            7

                                            1             -4         0

                 -------------------------------------------------------------

                            1              -4             0         7

Here 7 is the remainder

Now we write the answer in descending powers of x

1  -4  and 0 we have

The highest exponent in the question is x^3

when we divide by x-1 then highest exponent becomes x^2

Answer:

W >_2/7

Step-by-step explanation:

width = perimeter/2 - length

w = 74/2 - 5 = 32

32/4 = 8 - 3 = 5

The length of the rectangle is 5.

The width of the triangle is 32

As per the given values, the length of the rectangle is 29 meters and the width is 8 meters.

To find the length and width of the rectangle, we can use the information given: the length is 3 meters less than four times the width, and the perimeter is 74 meters. Let's assume the width is 'w' meters. So, the length would be '4w - 3' meters. The perimeter of a rectangle is found by adding the lengths of all its sides, which in this case is twice the length plus twice the width.

We can set up an equation to solve for 'w': 2(4w - 3) + 2w = 74. Solving this equation will give us the width of the rectangle, and we can substitute that value back to find the length.

Step 1: Set up the equation:

2(4w - 3) + 2w

= 74.

Step 2: Simplify the equation:

8w - 6 + 2w

= 74.

Step 3: Simplify further:

10w - 6 = 74.

Add 6 to both sides.

Step 4: Continue to simplify:

10w = 80.

Divide both sides by 10.

Step 5: Solve for 'w':

w = 8.

The width of the rectangle is 8 meters.

Step 6: Find the length

= 4w - 3

= 4(8) - 3 = 32 - 3

= 29 meters.

We can multiply 336 by 2/3 to find out.

2/3(336)

To make this easier, we can change 336 to 336/1, which does not change it's value.

Multiply 336 by 2.

336 * 2 = 672

Multiply 1 by 3.

1 * 3 = 3

Our new value is 672/3

Evaluate, divide both sides of the fraction by 3.

672/3 = 224.

3/3 = 1

Step-by-step explanation:

Alright, so we are given a triangle where all the angles are the same. Now - we need to write a proof that when IE bisects KM, it creates equal angles.

Given:

IKM is equiangular

IE is perpendicular to KM

This is enough to prove that IKE is congruent to IME because:

IEK and IEM are both 90 degrees, since IE is perpendicular to KM

KIE and MIE are the same degree measure, since I is being bisected.

This leaves us with only one angle remaining, and since we already know that the first two angles are congruent to their counterpart - we also know that IKE is congruent to IME because all interior angles of triangles add up to 180°, and we know the other two angle sets to be congruent.

Answer:

48,000. Look at the tens place, If the number is 5 or higher then you round up, if its 4 or lower the hundreds place stays the same. Since the number in the tens place is higher than 4 you round up, meaning you would add 1 to 9 which give you ten. You would carry that ten over, giving you 48,000

The correct answer is 48,000.

To round the number 47,963 to the nearest hundreds:

Identify the digit in the tens place, which is 6.

Since the digit in the tens place is greater than or equal to 5, round up the hundreds place.

The current digit in the hundreds place is 9.

Rounding up the hundreds place from 9 results in increasing it to the next number, which is 10.

When the hundreds place increases to 10, it affects the thousands place as well:

The 7 in the thousands place becomes 8, because adding 1 to 9 in hundreds place essentially adds 1,000 to the overall number.

Set all digits to the right of the hundreds place to zero.

Thus, 47,963 rounded to the nearest hundreds becomes 48,000.

This process ensures accurate rounding based on standard rounding rules.

That is, if F is a function such that [tex]F(x_1) \neq F(x_2)[/tex]

Then, [tex]x_1[/tex] and [tex]x_2[/tex] must be distinct.

But according to the given table,
