Alex's porch has a length and width of 12 feet each. He wants to paint the porch with a
water sealant that costs $35 per square foot. However, his wife wants him to change
the length of the porch to 14 feet. What would the difference in cost of applying sealant
be if Alex does extend his porch length?

Answer: Let's assume that Denise buys "x" pounds of pecans and "y" pounds of almonds. Since she wants to buy a mixture of nuts that weighs 5 pounds, we can write:

x + y = 5

We also know that Denise plans to spend $35.74 on nuts. The cost of the pecans and almonds combined is:

8.15x + 6.48y

So, we can write another equation:

8.15x + 6.48y = 35.74

We now have two equations with two variables, which we can solve simultaneously. Let's solve for "y" in the first equation:

y = 5 - x

We can substitute this expression for "y" into the second equation:

8.15x + 6.48(5 - x) = 35.74

Simplifying this equation, we get:

8.15x + 32.4 - 6.48x = 35.74

1.67x = 3.34

x = 2

So, Denise will buy 2 pounds of pecans. We can substitute this value of "x" back into the first equation to find the amount of almonds she will buy:

2 + y = 5

y = 3

Therefore, Denise will buy 2 pounds of pecans and 3 pounds of almonds.

Answer:

56 feet

Step-by-step explanation:

This is a trigonometry problem. It makes use of tangent. You can take the tangent of an angle and it will equal the side opposite divided by the side adjacent that isn't the hypotenuse.

In this case the angle is 35 degrees.

Tangent of the angle = opposite/ adjacent side

Tan(35) = (x)/(80)

Tan(35) = 0.7 so

(0.7)= (X)/(80)

Using algebra each side can be multiplied by 80.

(80)(.7)=X

56=x

X is in feet, so X is equal to 56 feet.

Hope this helps!

There are 8 cutting machines and each machine can cut 4 cases every 15 seconds, or 16 cases per minute (4 cases/15 seconds x 60 seconds/minute = 16 cases/minute). Therefore, all 8 machines can cut a total of 8 x 16 = 128 cases per minute.

If 25% of the machines are removed for maintenance, then 2 machines (25% of 8) will be taken out of service. This leaves 6 machines to continue cutting phone cases.

The 6 remaining machines can cut 6 x 16 = 96 cases per minute (since each machine still cuts 16 cases per minute). Therefore, the 6 remaining machines cut 128 - 96 = 32 fewer cases per minute than all 8 machines together.

So the answer is that the remaining machines cut 32 fewer cases per minute when compared to the number of cases per minute all 8 machines cut.

Therefore, the rate/slope between the two given points is 60.

In mathematics, slope refers to the steepness or incline of a line. It measures how much a line rises or falls over a certain horizontal distance, which is called the "run." Slope is usually denoted by the letter m and is defined as the ratio of the change in y (the vertical distance) to the change in x (the horizontal distance) between any two points on the line.

Here,

1. To find the rate/slope between the coordinates (1,60) and (2,120), we can use the slope formula:

slope = (change in y) / (change in x)

So, we have:

slope = (120 - 60) / (2 - 1)

= 60 / 1

= 60

2. The equation given is y = 65x, where x is the time in hours and y is the number of miles. To find the rate/slope, we can see that the equation is in the form of y = mx, where m is the slope. So, the slope of this equation is 65. Therefore, the rate/slope for the given equation is 65.

3.The slope of the graph is the change in y over the change in x for any two points on the line, whereas the slope of the equation is the coefficient of x. In this case, the slope of the graph is not given, so we cannot compare it directly to the slope of the equation.

1) In the set of triangles given, x = 48ft. The triangle are similar because the ratio of each side to the others are the same that is - 5:3
2) In this case, x = 16ft.
The Ratio is 1:1, thus they are similar.

1)

a )To solve for x, we must state that:

50/30 = 80/x

To solve for x in the equation:

50/30 = 80/x

You can begin by cross-multiplying the fractions. That means multiplying the numerator of the first fraction by the denominator of the second fraction, and vice versa. This gives:

50x = 30 * 80

Simplifying the right-hand side of the equation:

50x = 2400

Now, to solve for x, you can divide both sides of the equation by 50:

x = 2400/50

Simplifying this expression:

x = 48

Therefore, x is equal to 48.

b) The ratio is the comparison of two quantities. In this case, the ratio can be found by simplifying the fractions on both sides of the equation:

50/30 = 5/3

80/48 = 5/3 (by dividing both numerator and denominator by 16)

Therefore, the ratio is 5:3, which means that the two quantities being compared are in the ratio of 5 to 3.

2)

a) To solve for x, we must state that:

if 6/4.5 = x/12

To solve for x in the equation:

6 / 4.5 = x / 12
6 * 12 = 4.5 * x
x = (6 * 12) / 4.5
x = 72 / 4.5

x = 16

b)

To justify that both triangles are similar, we must look at the ratio of their sides.


The ratio between the first fraction 6/4.5 and the second fraction 16/12 can be found by simplifying both fractions to their lowest terms and then comparing the resulting values.

To simplify 6/4.5, we can divide both the numerator and denominator by their greatest common factor, which is 1.

6/4.5 = (6 ÷ 1)/(4.5 ÷ 1) = 6/4.5

To simplify 16/12, we can divide both the numerator and denominator by their greatest common factor, which is 4.

So the simplified ratio between the two fractions is:

6/4.5 : 16/12

= 6/4.5 : 4/3

To compare these ratios, we can cross-multiply to get:

(6 * 3) : (4.5 * 4) = 18 : 18 = 1 : 1

Therefore, the ratio between 6/4.5 and 16/12 is 1:1 or simply 1.

This means the two triangles are similar.

The value of x when triangles CDE and CBA are similar is 9.

In geometry, a triangle is a polygon with three sides and three angles. It is one of the most basic and fundamental shapes in mathematics, and it appears frequently in geometry, trigonometry, and other branches of mathematics. A triangle can be classified based on the length of its sides and the measure of its angles. Triangles have many important properties and relationships that make them useful in mathematics and other fields. For example, the sum of the interior angles of a triangle is always 180 degrees, and the Pythagorean theorem relates the sides of a right triangle to the length of its hypotenuse. Triangles also appear frequently in trigonometry, where they are used to model and solve problems involving angles and distances.

Here,

Since the triangles CDE and CBA are similar, we know that the corresponding sides are proportional. Therefore, we can set up the following proportion:

CD / CB = DE / BA

Substituting the given values, we get:

30 / (11x + 11) = 21 / 77

Cross-multiplying and simplifying, we get:

30 * 77 = 21 * (11x + 11)

2310 = 231x + 231

Subtracting 231 from both sides, we get:

2079 = 231x

Dividing both sides by 231, we get:

x = 9

The probability of getting two heads and one tail in any order is 3/8.

What is probability ?

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. For example, the probability of flipping a coin and it landing heads up is 0.5, because there are two equally likely outcomes (heads or tails) and one of them is heads.

Probabilities can also be expressed as percentages or fractions. For instance, a probability of 0.25 can be expressed as a percentage of 25%, or as a fraction of 1/4.

According to the question:
The sample space for flipping three coins is:
HHH

HHT

HTH

THH

HTT

THT

TTH

TTT

where H represents heads and T represents tails.

Out of these eight outcomes, there are three outcomes in which two heads and one tail come up in any order: HHT, HTH, and THH. Therefore, the probability of getting two heads and one tail in any order is 3/8, or 0.375, which can also be written as a fraction.

To see why this is the case, you can also use a tree diagram to represent the sample space:
     H              T

   /   \          /   \

  H     T        H     T

 / \   / \      / \   / \

H   T H   T    H   T H   T

Each branch represents the outcome of one coin flip, and the branches lead to the possible outcomes of flipping three coins. The outcomes with two heads and one tail are HHT, HTH, and THH, which occur in three out of the eight possible outcomes, as previously stated. Therefore, the probability of getting two heads and one tail in any order is 3/8.

The correct answer is: √(6² + 2²), and tan⁻¹(2/6) represents the magnitude and direction angle of the vector.

What is Pythagoras' Theorem?

Pythagoras' theorem is a fundamental principle in geometry that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The magnitude of a vector is the length of the vector. For a vector that passes from the origin to the point (6,2),

the magnitude can be calculated using the Pythagorean theorem, which states that for a right triangle with legs of length a and b and hypotenuse of length c,

c² = a² + b².

In this case, the vector is the hypotenuse of a right triangle with legs of length 6 and 2, so the magnitude is:

magnitude = √(6² + 2²) = √(40) = 2*√(10)

The direction angle of a vector is the angle that the vector makes with the positive x-axis, measured counterclockwise. The direction angle can be calculated using the inverse tangent function, which is the inverse of the tangent function. In this case, the direction angle is:

direction angle = tan⁻¹(2/6) = tan⁻¹(1/3)

Therefore, the correct answer is: √(6² + 2²), and tan⁻¹(2/6) represents the magnitude and direction angle of the vector.

Oliver's result of 85.4° for angle A is wrong. This is because the sum of angles of a triangle should add up to 180°.

Triangles are classified according to the lengths of their sides and the measure of their angles.

In this triangle, we have two angles, angle A and angle B. If angle A is 85.4°, then angle B must be 94.6°. But, the angles of a triangle should add up to 180°, which is not the case here.

We can solve for angle A using the Law of Cosines:

Cos A = (b² + c² - a²)/2(bc)

A = [tex]cos^{-1}[(15^2 + 10^2 - 12^2)/2(15)(10)]}[/tex]

A = [tex]cos^{-1}(0.6)}[/tex]

One of the main goals of SPC is to distinguish between normal random variation in the process and variation that is caused by assignable or special causes.

By identifying and eliminating the assignable causes of variation, the process can be improved and the quality of the output can be maintained or improved over time. Therefore, the primary objective of SPC is to detect assignable cause variations versus normal random variations in the process.

Options 1, 2, and 4 are related to quality control and monitoring, but they do not capture the essence of what SPC is trying to achieve. SPC is focused on monitoring and improving the process, rather than simply accepting or rejecting batches of raw materials or finished goods or identifying variable versus attribute measures.

Therefore, the correct option is '3' - detect assignable cause variations versus normal random variations in the process.

Yes, it is an observational study because the groups are not randomly assigned by the researchers. Instead, the students self-select which group to join based on their own TV watching habits.

An observational study is a type of study where the researchers observe the people in the study and take measurements or survey them. The researchers do not modify or control any variable in this type of study. In other words, an observational study observes, records and concludes based on the observation of data collected. It does not make use of control groups or experimental treatments in order to arrive at a conclusion.

From the given question, this is an observational study because the groups were not randomly assigned by the researchers; rather, the students self-selected which group they wanted to join based on their television-watching habits. Additionally, the researchers did not manipulate any variables or conditions, and the study only measured the characteristics and behaviors of the two pre-existing groups. Therefore, the researchers could only observe the differences between the groups, but they could not determine causality or control any extraneous variables that may have influenced the results.

For given functions, the correct statement is D i.e. The graph of h is the graph of g vertically shifted up 1 unit.

What is the definition of a function?

A function is a rule or correspondence in mathematics that assigns each element in a set (called the domain) to a unique element in another set (called the range). In other terms, a function is a connection between two sets of numbers or quantities that creates exactly one output value for each input value (or argument).

Now,

The function h(x) = g(x) + 1 is obtained by taking the function g(x) = x² and adding 1 to its output for every input value of x. This means that the graph of h will be the same as the graph of g, but shifted up by 1 unit for all points on the graph.

Therefore, the correct statement that describes how the graph of h is different from the graph of g is:

D. The graph of h is the graph of g vertically shifted up 1 unit.

Rounding to the nearest tenth of a meter, we get the width of the rectangle to be approximately 7.5 meters.

Area is a measure of the size of a two-dimensional surface, such as the surface of a plane or a geometric shape. It is usually measured in square units, such as square meters (m²) or square feet (ft²).

Here,

Let's assume that the width of the rectangle is x meters. Then, according to the problem statement, the length of the rectangle is 3x meters. The area of a rectangle is given by the formula:

A = length x width

Substituting the values from the problem statement, we get:

170 = (3x) x (x)

Simplifying and solving for x, we get:

3x² = 170

x² = 56.67

x ≈ 7.5
