Step-by-step explanation:

Final answer:

The volume of the shoe box is calculated using the formula for the volume of a rectangular prism, resulting in a total of 450 cubic inches.

Explanation:

The formula for finding the volume of a rectangular prism (which is the shape of a shoe box) is Volume = Length × Width × Height. However, before calculating, we need to ensure all dimensions are in the same unit. Since the given width is in mixed number form, we will convert 6 2/3 inches to an improper fraction which is 20/3 inches. We then multiply the length, width, and height.

Volume = (13.5 inches) × (20/3 inches) × (5 inches)
Volume = (13.5 × 20/3 × 5) cubic inches
Volume = (270/3 × 5) cubic inches
Volume = (90 × 5) cubic inches
Volume = 450 cubic inches

The shoe box's volume is 450 cubic inches.

Answer:

x=16, x=8

Step-by-step explanation:

since x in |x-12| can be both negative and positive, we have to find two numbers for each senario. if x-12 is negative, we flip them so it becomes 12-x. so 12-x=4 is easily solved and the answer would be 8. if it is positive, we would keep it and x-12 would be 4. we also solve this to get 16. we can check our work by putting them in to get 16-12 is 4 and |8-12| is 4

ANSWER

y-intercept:

(0,-13)

x-intercept:

[tex](4 \frac{1}{3} ,0)[/tex]

EXPLANATION

The given line has equation

[tex]y + 1 = 3(x - 4)[/tex]

At y-intercept , x=0.

This implies that;

[tex]y + 1 = 3(0 - 4)[/tex]

[tex]y = - 12 - 1[/tex]

[tex]y = - 13[/tex]

The y-intercept is

(0,-13).

At x-intercept y=0,

This implies that;

[tex]0+ 1 = 3(x - 4)[/tex]

[tex] \frac{1}{3} = x - 4[/tex]

[tex] \frac{1}{3} + 4 = x[/tex]

[tex]4 \frac{1}{3} = x[/tex]

The x-intercept is

[tex](4 \frac{1}{3} ,0)[/tex]

Answer:

x-intercept = [tex]\frac{13}{3}[/tex]

y-intercept = [tex]-13[/tex]

Step-by-step explanation:

We are given the following equation of a line and we are to find the x and y intercepts for it:

[tex] y + 1 = 3 ( x - 4 ) [/tex]

In order to find the x-intercept, we will substitute 0 in place of y to get:

[tex] 0 + 1 = 3 ( x - 4 ) \\\\ 1 = 3 x - 12 \\\\ 3 x = 1 + 12 \\\\ x = \frac { 13 } { 3 } [/tex]

And to find the y-intercept, we need to substitute 0 in place of x:

[tex] y + 1 = 3 ( 0 - 4 ) \\\\ y + 1 = -124 \\\\ y = - 12 - 1 \\\\ y = - 13 [/tex]

So the x-intercept is [tex]\frac{13}{3}[/tex] while the y-intercept is [tex]-13[/tex].

Answer:

Step-by-step explanation:

The area of a triangle is base*height/2

So one triangle is 2*4/2=4

Multiplied by 4 sides, 4*4=16

Finally the base is a square, so 2*2=4

Therefore the entire shape is 16+4=20 square feet

The amount of paper it will take to make each tree, including the bottom is 20 ft²

Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object.

Surface area of paper tree = sum of areas of those 4 slant standing triangles + area of base

Area of each of those 4 triangles are same (assuming they're symmetric).

Each triangle has height of 4 ft and base of 2 ft. (the base is a square of side length 2 ft).

Thus, we get:

Area of 4 triangles = 4(area of each tree ) = [tex]4\left (\dfrac{1}{2} \times \text{base} \times \text{height}\right) = 4\left (\dfrac{1}{2} \times 2 \times 4\right) = 16 \: \rm ft^2[/tex]

Area of square base = [tex]\text{side}^2 = 2^2 = 4 \: \rm ft^2[/tex]

Thus, we get:

Surface area of paper tree = 16 + 4 = 20 ft²

Thus, the amount of paper it will take to make each tree, including the bottom is  20 ft²

[tex] \frac{.7}{1 - .1} = \frac{.7}{.9} = \frac{7}{9} [/tex]

To factor out the greatest common factor from 30 and 42, first, find the GCF. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The greatest common factor is 6. Using the distributive property, 30 + 42 becomes 6(5 + 7). So, the final answer is 6 times the sum of 5 and 7, which is 72.

To factor out the greatest common factor (GCF) from the expression 30 + 42, we first need to find the GCF of the two numbers, which is 6. Then we can rewrite the expression using the distributive property.

Step 1: Find the GCF of 30 and 42:

The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.

The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.

The common factors are 1, 2, 3, and 6. The greatest common factor is 6.

Step 2: Rewrite the expression using the GCF:

[tex]\[30 + 42 = 6 \times 5 + 6 \times 7\][/tex]

Step 3: Apply the distributive property:

[tex]\[30 + 42 = 6 \times (5 + 7)\][/tex]

Step 4: Perform the addition inside the parentheses:

[tex]\[30 + 42 = 6 \times 12\][/tex]

Step 5: Multiply:

30 + 42 = 72

So,30 + 42 equals 72 after factoring out the greatest common factor using the distributive property.

Answer:

[tex]\large\boxed{y=-\dfrac{2}{3}x+\dfrac{1}{3}}[/tex]

Step-by-step explanation:

The skope-intercept form:

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

m - slope

b - y-intercept

The formula of a slope:

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

We have the points (2, -1) and (5, -3). Substitute:

[tex]m=\dfrac{-3-(-1)}{5-2}=\dfrac{-3+1}{3}=\dfrac{-2}{3}=-\dfrac{2}{3}[/tex]

We have the equation:

[tex]y=-\dfrac{2}{3}x+b[/tex]

Put the coordinates of the point (2 , -1) to the equation:

[tex]-1=-\dfrac{2}{3}(2)+b[/tex]

[tex]-1=-\dfrac{4}{3}+b[/tex]           add 4/3 to both sides

[tex]\dfrac{1}{3}=b\to b=\dfrac{1}{3}[/tex]

Finally we have:

[tex]y=-\dfrac{2}{3}x+\dfrac{1}{3}[/tex]

The correct answer is: Triangle MNO

A reflection of a triangle over the X-axis involves flipping the triangle about this axis. Each point in triangle ABC (A, B, and C) is reflected to a corresponding point A', B', and C' in the reflected triangle such that their Y-coordinates are negated while the X-coordinates remain the same.

To understand the concept of the reflection of a triangle, you need to visualize flipping the triangle over a line, in this case, the X-axis. When a triangle named ABC is reflected over the X-axis, the positions of the points change as follows: A (x, y) becomes A' (x,-y), B (x, y) becomes B' (x, -y), and C (x, y) becomes C' (x, -y). Therefore, the triangle that is a reflection of triangle ABC over the X-axis is triangle A'B'C'.

Answer:

L ∪ (M ∩ N) = {0, 10, 20, 40, 80, 100}

Step-by-step explanation:

L ∪ (M ∩ N) means "take what's common of set M and set N" and then "add it to all the elements of set L".

So, what are the common elements of set M and set N?

They are 10 & 20. So,

M ∩ N = {10,20}

Now, we add it to all the elements of set L. Note that we don't need to count 20 twice.

Thus L ∪ (M ∩ N) = {0, 10, 20, 40, 80, 100}

Step-by-step explanation:

The pipes can fill the pool individually in 16 and 20 hours respectively, by solving the simultaneous equations: 1/x + 1/y = 1/5 and 1/2x + 1/2y = 18.

Let's assume one pipe can fill the pool in x hours, while the other pipe can fill it in y hours. When the two pipes work together, they complete one job in 5 hours, which can be expressed as 1/x + 1/y = 1/5.

When each pipe fills half the pool, it takes 18 hours. Since each of them is doing half the work, this can be represented as 1/2x + 1/2y = 18.

To solve these simultaneous equations, it is best to use the substitutive method. We can set the two equations equal to each other to get x = 36 - y. Plugging this into the first equation and solving for y, we find y = 20. Substituting y back into the equation x = 36 - y, we find x = 16.

So, one pipe could fill the pool alone in 16 hours, while the other could do it in 20 hours.

The first pipe would take approximately 6.92 hours to fill the pool if it were working alone, and the second pipe would take 18 hours to fill the pool if it were working alone.

Let's assume that the first pipe can fill the pool in x hours, and the second pipe can fill the pool in y hours.

When the two pipes fill the pool together, they can complete the job in 5 hours. So, their combined rate of work is 1/5 of the pool per hour.

When the first pipe fills half the pool, it takes over for the second pipe, which then finishes filling the pool. This entire process takes 18 hours. So, the first pipe fills half the pool in 18 hours, which means that its rate of work is 1/18 of the pool per hour.

Using the concept of work done, we can set up the following equation:

1/x + 1/y = 1/5 (equation 1)

1/y = 1/18 (equation 2)

Solving the equations simultaneously, we can find the values of x and y:

From equation 2, y = 18 hours.

Substituting the value of y in equation 1, we get:

1/x = 1/5 - 1/18 = (18 - 5)/90 = 13/90.

Therefore, x = 90/13 hours.

So, the first pipe would take approximately 6.92 hours to fill the pool if it were working alone, and the second pipe would take 18 hours to fill the pool if it were working alone.

Answer:

The correct answer is: descriptive and inferential statistics.

Step-by-step explanation:

The two branches of the study of statistics are generally referred to as descriptive and inferential statistics.

Descriptive statistics are the brief summary statistic which summarizes a given data set, which can be a representation of the entire population or just a sample of it.

While Inferential statistics is the way data analysis is used to deduce the properties of an underlying probability distribution.

The study of statistics generally branches into descriptive statistics, which involves summarizing and displaying data, and inferential statistics, which makes predictions about a population based on sampled data.

The two branches of the study of statistics are generally referred to as descriptive statistics and inferential statistics. Descriptive statistics involves the organization, summarization, and display of data. It seeks to describe a situation or sample population without offering any conclusions or inferences about the data. Examples include calculating averages, measures of central tendency like mean, median, mode, and variability measures such as range, variance, and above all standard deviation.

On the other hand, inferential statistics is a method to make predictions or inferences about a population based on a sample of data. It is used when it is not practical or impossible to examine the entire population. Examples of inferential statistics methods include hypothesis testing, chi-square tests, t-tests, ANOVA, regression analysis etc.

So a/b would equal 2.

4b/a indicates that you are going to multiply b times 4, meaning that in this scenario you would multiply 2 times 4.

4(2) = 8

and 8 divided by (4) is 2.

Why 4? Because remember a = 4 (in this scenario).

Other examples:

20 miles

Step-by-step explanation:

The formula for distance is

d =rt  where r  is the rate and t is the time

We need to convert the time to hours since the rate is in mph

15 minutes * 1 hour/ 60 minutes = 1/4 hour = .25 hours

d = (80 mph) * .25 hours

d = 20 miles

The train goes 80 miles in an hour which is 60 minutes. 60 minutes divided by 15 minutes equals 4. 80 miles divided by 4 equals 20 miles. The train went 20 miles in 15 minutes.
