Answer:

Step-by-step explanation:

Y      - the measure of angle Y

5Y    - five times the measure of angle Y

5Y-12     - twelve less than five times the measure of angle Y  

Z = (5Y - 12)°

Y and Z being linear pair of angles means they create a straight angle so they add to 180°

Y + Z = 180

Y + 5Y - 12 = 180

 6Y = 192

   Y = 32

Z = (5•32 - 12)° = (160 - 12)° = 148°

For closet

For rolls:-

Cylindrical body

Volume:-

Total rolls:-

Answer:

1372

Step-by-step explanation:

Rectangular closet dimensions:

Modelling the roll of toilet paper as a cylinder with dimensions:

If we sit the rolls of toilet paper in the closet with their circular ends as their bases, then we can calculate the number of rolls that cover the base of the closet by dividing the length (and width) of the closet by the diameter of the toilet roll.

⇒ 36 in ÷ 5 in = 7.2 in

Therefore, we can fit 7 toilet rolls along the length and 7 toilet rolls along the width of the closet, meaning that we can fit 7 × 7 = 49 toilet rolls over the base of the closet.

Now calculate how many toilet rolls we can stack on top of each other.

To do this, divide the height of the closet by the height of the toilet roll:

⇒ 108 in ÷ 3.75 in = 28.8

Therefore, we can stack 28 layers of 49 toilet rolls in the closet.

So the total number of toilet rolls = 28 × 49 = 1372

There are other ways of stacking the toilet rolls in the closet (for example, turning them on their side), however, we cannot calculate the number of rolls the closet fits by simply dividing the volume of the closet space by the volume of a toilet roll, since the toilet rolls are cylinders and so there will always be some space between them.

Step-by-step explanation:

Given that,

Length of a toy jeep = 12 1/2 inches = 25/2 inches

Length of an actual jeep = 18 3/4 feet = 75/4 feet

1 foot = 12 inches

75/4 feet = 225 inches

We need to find the ratio of the length of the toy jeep to the length of the actual jeep.

\(R=\dfrac{\dfrac{25}{2}}{225}\\\\=\dfrac{1}{18}\)

So, the required ratio is 1:18.

According to the evidence from graph a and graph b, graph a indicates that the model for the data was a good fit because it is a random.

Hence, the correct option is B.

Based on graph a, the residual plot shows a random scattering of points around the horizontal line at y=0. This indicates that the residuals (the differences between the observed and predicted values) are distributed randomly and do not show any clear pattern. This suggests that the data points are evenly distributed around the regression line, indicating a good fit for a linear regression model.

On the other hand, graph b shows a residual plot with a clear pattern or trend. The residuals are not randomly scattered, but instead show a curved pattern or a fan-like shape. This indicates that the model used to fit the data may not be appropriate, as it is not capturing the underlying relationship between the variables accurately.

Hence, the correct option is B.

The volume of the solid is 4,503.22 in³.

What is volume?

A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder, or a sphere. Different shapes have different volumes

The volume of a solid with a hollow cylinder can be calculated by subtracting the volume of the inner cylinder from the volume of the outer cylinder.

Assuming the dimensions in the figure are in inches, the outer cylinder has a height of 17 inches and a radius of 9 inches, so its volume is:

\(V_{outer} = \pi * r^2 * h\)

= π × 9² × 17 ≈ 4,842.51 in³

The inner cylinder has a height of 12 inches and a radius of 3 inches, so its volume is:

\(V_{inner} = \pi * r^2 * h\) = π × 3² × 12 ≈ 339.29 in³

To find the volume of the solid, we need to subtract the volume of the inner cylinder from the volume of the outer cylinder:

\(V_{solid }= V_{outer} - V_{inner}\)

≈ 4,842.51 - 339.29 ≈ 4,503.22 in³

Hence, the volume of the solid is 4,503.22 in³.

The graph of the model is illustrated below and  the resistance when x = 85 is 1.12

The resistance of a conductor (such as a wire) is a measure of the opposition it presents to the flow of electric current. The resistance of a wire is dependent on various factors such as its length, cross-sectional area, and material. In this case, we are looking at the resistance of 1000 feet of solid copper wire, where the diameter of the wire is given in mils (0.001 inches).

The resistance of the wire can be approximated using the mathematical model:

=> y = 10,770/x² - 0.375,

where x is the diameter of the wire in mils and y is the resistance in ohms. The model is valid for values of x ranging from 5 to 100.

To complete the table, you need to plug in different values of x into the model and solve for y. For example, when x = 10,

=> y = 10,770/(10²) - 0.375 = 106.975 ohms.

The graph of the model can then be plotted by plotting the points (x,y) from the table and connecting them with a smooth curve. The graph can be used to estimate the resistance of the wire when x = 85.5 mils by finding the y-coordinate of the corresponding point on the graph.

Finally, you can use the model to algebraically confirm the estimate you found from the graph by plugging in the value x = 85.5 into the model and solving for y then we get the value as 1.12. This should give you the same answer as you found from the graph.

In conclusion, the resistance of a wire can be estimated using the mathematical model and can be used to make predictions about the resistance for different wire diameters.

Step-by-step explanation:

d = 935 − 12t

d = 517 + 26t

how many months will the number of DVDs sold equal the number of Blu-ray discs sold

Equate both equations to solve for the number of months

935 − 12t = 517 + 26t

935 - 517 = 26t + 12t

418 = 38t

t = 418 / 38

t = 11 months

How many of each is sold in that month?

d = 935 − 12t

= 935 - 12(11)

= 935 - 132

Answer:

  g = -16

Step-by-step explanation:

This is a "one-step" linear equation. To solve it, we need to have the coefficient of g be 1, not 3/4.

Since we know how to multiply fractions, we know that ...

  (3/4)(4/3) = (3·4)/(4·3) = 12/12 = 1

That is, we can multiply both sides of the equation by 4/3 and that will give us a coefficient of 1 for g.

 (4/3)(3/4)g = (4/3)(-12)

  g = (4·(-12))/3 = -48/3 = -16

The solution is g = -16.

37. The given differential equation possesses constant solutions.

38. The given differential equation does not possess constant solutions.

37. In order to determine whether the given differential equation possesses constant solutions, we need to check if the derivative of the dependent variable (y) with respect to the independent variable (x) is equal to zero. In this case, the given equation is 3xy' + 5y = 10.

Taking the derivative of y with respect to x, we get y' = (10 - 5y)/(3x). Since y' is dependent on both x and y, it is not equal to zero for all values of x and y. Therefore, the given differential equation does not possess constant solutions.

38. Similarly, for the differential equation y' * y²+ 2y - 3 = 0, taking the derivative of y with respect to x, we get y' = (3 - 2y)/(y²). Again, y' is not equal to zero for all values of x and y. Therefore, the given differential equation does not possess constant solutions.

In both cases, the derivative of y with respect to x is not identically zero, indicating that the differential equations do not have constant solutions.

To determine the number of 4-digit positive integers that satisfy the given conditions, we need to count the possibilities for each condition and then find their intersection.

Condition (A):

Each of the first two digits must be 1, 4, or 5.

Since there are 3 choices for each of the first two digits, there are

3 x 3 = 9 possibilities for condition (A).

Condition (B):

The last two digits cannot be the same digit.

There are 10 choices for the first digit, and for each of these choices, there are 9 choices for the second digit (excluding the chosen digit). Therefore, there are 10 x 9 = 90 possibilities for condition (B).

Condition (C): Each of the last two digits must be 5, 7, or 8.

There are 3 choices for each of the last two digits, resulting in 3 x 3 = 9 possibilities for condition (C).

To find the total number of 4-digit positive integers satisfying all three conditions, we multiply the possibilities for each condition together:

9 x 90 x 9 = 7290

Step-by-step explanation:

the problem with it isn't an excuse if it isn't an

To show that the general term of the quadratic number pattern is given by \(tn = n^2 + 4n - 12\) , we need to find a quadratic expression that fits the given pattern.

Let's examine the given sequence: -7, 0, 9, 20. We notice that each term is increasing by a certain amount.

First, let's find the differences between consecutive terms:
0 - (-7) = 7
9 - 0 = 9
20 - 9 = 11

We observe that the differences between consecutive terms are not constant, so this indicates that the sequence is not linear.

To determine if the sequence follows a quadratic pattern, let's find the second differences:
9 - 7 = 2
11 - 9 = 2

The second differences are constant, which suggests a quadratic pattern.

Now, let's find the quadratic expression. We know that the general term of a quadratic sequence can be written as \(tn = an^2 + bn + c\), where a, b, and c are constants to be determined.

Using the given terms, we can form three equations:

1.\(For n = 1: -7 = a(1)^2 + b(1) + c\)
2. \(For n = 2: 0 = a(2)^2 + b(2) + c\)
3.\(For n = 3: 9 = a(3)^2 + b(3) + c\)

Simplifying these equations, we get:
1. a + b + c = -7
2. 4a + 2b + c = 0
3. 9a + 3b + c = 9

Solving this system of equations, we find a = 1, b = 4, and c = -12.

Therefore, the general term of the quadratic number pattern is given by\(tn = n^2 + 4n - 12\).

The general term of the quadratic number pattern is \(tn = n^2 + 4n - 12\).

Let's start with the two consecutive numbers. We don't know what are the two numbers that are side by side (consecutive), so we'll use variables but with a twist...instead of x and y, we'll use x for the first number and x+1 for the other number because the other number is 1 more than the value of x. So part of the problem looks like this: (x)+(x+1).

The problem says "the sum of one-third of the first and one-fourth of the second equal 9." One-third of the first would be 1/3(x) and one-fourth of the second would be 1/4(x+1) so if the sum is 9, then the problem is:

1/3(x)+1/4(x+1)=9.

Since we need to solve for x, we must remove the fractions. Right now they have different denominators so we need to make them the same. The least common denominator is 12 so that's the denominator to use, thus...

1/3x becomes 4/12(x) and 1/4(x+1) becomes 3/12(x+1).

Now the equation is 4/12(x)+3/12(x+1)=9

Multiply both sides by 12 so the denominators are gone:

[12•]4/12x+3/12(x+1)=9•12

4x+3(x+1)=108

Using distribution, it's now 4x+3x+3=108. Continuing on with the math...

7x+3=108

7x=105

x=15

We found x! If x=15 the the next number must be 16. Let's check the math: Does 1/3(15)+1/4(16)=9?

5+4=9 and 9=9 so YES! The numbers are 15 and 16
