Answer:

The length is 24, width is 6

Step-by-step explanation:

Since we know the length and width cannot both be 12 (to make 144), other factors of 12 can be tested to be a product of 144. Half of 12 is 6, and 24 * 6 = 144. If we add up 12 + 12 + 6 + 6, we get 60, or the given perimeter.

The length and width of the rectangle, set up and solve a system of equations based on the given area and perimeter. By factoring the quadratic equation obtained from the area and perimeter formulas, it is determined that the rectangle's width is 12 inches and its length is 18 inches.

The length and width of a rectangle with an area of 144 square inches and a perimeter of 60 inches, we can set up a system of equations using the formulas for area and perimeter of a rectangle, which are Area = length  imes width and Perimeter = 2  imes (length + width), respectively. Let the length be represented by 'l' and the width by 'w'.

Step 1: Set up the equations

Area = l  times w = 144
Perimeter = 2l + 2w = 60

Step 2: Solve the system of equations

First, simplify the perimeter equation to get l + w = 30. Then, express l in terms of w: l = 30 - w. Now substitute l in the area equation: (30 - w)w = 144.

Step 3: Solve the quadratic equation

Expand the equation: 30w - w² = 144.
Rearrange to form: w²- 30w + 144 = 0.
Factoring the quadratic equation gives: (w - 12)(w - 18) = 0.

Step 4: Find w and l

Setting each factor equal to zero gives us two possible widths: w = 12 or w = 18. If w = 12, then l = 30 - w = 18. If w = 18, then l = 30 - w = 12. Since both options give us the same pair of numbers, and a rectangle's sides can be switched without changing its shape, the rectangle's width is 12 inches and its length is 18 inches, or vice versa.

1 and 5 are the same angle, so if added together equal 100, then each angle is 50 degrees.

Angle 1 and angle 2 make a straight line which means they need to equal 180 degrees.

Angle 2 = 180 - 50 = 130 degrees.

Answer:

angle 2= 130

Step-by-step explanation:

180-50=130

B is the correct answer.

Look at the picture of it then match it .. the answer is B

Answer:

Dividing two binomials will not always result in a polynomial. For instance, divide (x+2) over (x+3) and we won't get a polynomial. The result is known to be a rational expression but not a polynomial. So that's why division is not closed for polynomials.

Contrast that with addition, subtraction and multiplication. For any of those operations taking two polynomials and adding them, subtracting them, or multiplying them will lead to another polynomial. That's why these operations are closed for polynomials.

Answer:

x = 16

y = 11

Step-by-step explanation:

Let the larger number = x

Let the smaller number = y

x  - y = 5

x = 2*y - 6

Put the second equation into the first. Substitute for x

2y - 6 - y = 5                          

combine

y - 6 = 5

and 6 to both sides.

y - 6 + 6 = 5 + 6

Combine

y = 11

=======================

Find x

x - y = 5           Substitute for y

x - 11  = 5          Add 11 to both sides.

x - 11+11=5+11

x = 16

Answer:

A sphere

Step-by-step explanation:

A sphere is a round three dimensional object with no sharp corners or vertexes.  Since a basketball fits this criteria, it is a sphere.

To determine the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum of a data set, you need to follow these steps:

1. Order the Data Set: Arrange the data set in ascending order.

2. Minimum and Maximum: Identify the smallest and largest values in the ordered data set.

3. Median (Q2): This is the middle value of the data set. If there is an odd number of observations, it is the middle one. If there is an even number of observations, it is the average of the two middle values.

4. First Quartile (Q1): This is the median of the first half of the data (the lower 50%). If the number of observations is odd, do not include the median in this half.

5. Third Quartile (Q3): This is the median of the second half of the data (the upper 50%). If the number of observations is odd, do not include the median in this half.

Let's consider an example data set to illustrate these steps:

Example Data Set: 3, 7, 8, 5, 12, 14, 21, 13, 18

1. Order the Data Set: 3, 5, 7, 8, 12, 13, 14, 18, 21

2. Minimum and Maximum:

  - Minimum = 3

  - Maximum = 21

3. Median (Q2):

  - Since there are 9 data points (odd number), the median is the 5th value.

  - Median = 12

4. First Quartile (Q1):

  - The lower half of the data (excluding the median) is: 3, 5, 7, 8

  - Median of this lower half = (5 + 7) / 2 = 6

5. Third Quartile (Q3):

  - The upper half of the data (excluding the median) is: 13, 14, 18, 21

  - Median of this upper half = (14 + 18) / 2 = 16

So, the five-number summary for the example data set is:

- Minimum = 3

- First Quartile (Q1) = 6

- Median (Q2) = 12

- Third Quartile (Q3) = 16

- Maximum = 21

Let D = difference between mean and median of data.

Mean = (22 + 8 + 10 + 18 + 12 + 20)/6

Mean = 90/6

Mean = 15

Let m = median

m = 8, 10, 12, 18, 20, 22

m = (12 + 18)/2

m = 30/2

m = 15

D = M - m

D = 15n- 15

D = 0

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

[tex]m = \frac {y2-y1} {x2-x1}[/tex]

According to the data we have two points through which the line passes, then we can find the slope:

[tex](x1, y1) = (0,3)\\(x2, y2) = (7,0)[/tex]

[tex]m = \frac {0-3} {7-0} = - \frac {3} {7}[/tex]

Then, the equation is given by:

[tex]y = - \frac {3} {7} x + b[/tex]

We substitute a point to find "b":

[tex]3 = - \frac {3} {7} (0) + b\\b = 3[/tex]

Finally, the equation is:

[tex]y = - \frac {3} {7} x + 3[/tex]

Answer:

[tex]y = - \frac {3} {7} x + 3[/tex]

To determine how long it will take for $10,000 to triple with a continuous compounded interest rate of 5.5%, we use the continuous compound interest formula. Solve the equation for t by taking the natural logarithm of both sides and dividing by the interest rate, which yields t = ln(3) / 0.055.

The subject at hand deals with Continuous Compound Interest. The formula used to calculate this is A = Pe^(rt), where A is the final amount, P is the initial principal, r is the yearly interest rate and t is the time in years.

In this case, the initial principal P is $10,000, the final amount (A) we want is $30,000 (because we want to triple the money), and the rate r is 5.5% or 0.055 as a decimal. We want to find t.

Plugging into the formula, we get 30000 = 10000 * e^(0.055t). Dividing both sides by 10000 yields 3 = e^(0.055t). If we take the natural log (ln) of both sides, the equation simplifies to ln(3) = 0.055t. Finally, solving for t, we get t = ln(3) / 0.055.

This will give you the number of years it'll take for the money to triple at an interest rate of 5.5% compounded continuously.

Step-by-step explanation:

32 touchdowns divided by 12 interceptions

32/12 = 26.66666%

26.66666 rounds up to 26.67%

Final answer:

The simplified ratio of touchdowns to interceptions that Max threw is 8:3, found by dividing both the number of touchdowns (32) and interceptions (12) by their greatest common divisor, which is 4.

Explanation:

To find the most simplified form of the ratio of touchdowns to interceptions that Max threw, we divide the number of touchdowns by the number of interceptions. Max threw 32 touchdowns and 12 interceptions. To simplify this ratio, we need to find the greatest common divisor (GCD) that both numbers share. In this case, the GCD of 32 and 12 is 4.

Dividing both numbers by the GCD, we get: 32 ÷ 4 = 8 and 12 ÷ 4 = 3. Therefore, the simplified ratio of touchdowns to interceptions is 8:3.
