How would you represent Andy’s descent as a unit rate? Express your answer as an integer.
Enter your answer in the box.

Answer:

19.81% off

Step-by-step explanation:

percentage decrease = new-old/old

599-747/ 747   = -148/747  

-148/747 x 100 = -19.81%

so the price has been reduced by 19.81%

The solution set over the interval [0°, 360°) is {120°, 240°}. The correct choice is (c) {120°, 240°}.

The given equation is csc²θ + 2 cotθ = 0 over the interval [0°, 360°).

To solve this equation, we first need to simplify it using trigonometric identities as follows:

csc²θ + 2 cotθ

= 0(1/sin²θ) + 2(cosθ/sinθ)

= 0(1 + 2cosθ)/sin²θ = 0

We can then multiply both sides by sin²θ to get:

1 + 2cosθ = 0

Now, we can solve for cosθ as follows:

2cosθ = -1cosθ

= -1/2

We know that cosθ = 1/2 at θ = 60° and θ = 300° in the interval [0°, 360°).

However, we have cosθ = -1/2, which is negative and corresponds to angles in the second and third quadrants. To find the solutions in the interval [0°, 360°), we can use the following formula: θ = 180° ± αwhere α is the reference angle. In this case, the reference angle is 60°.

So, the solutions are:θ = 180° + 60° = 240°θ = 180° - 60° = 120°

Therefore, the solution set over the interval [0°, 360°) is {120°, 240°}. The correct choice is (c) {120°, 240°}.

68.5% of Colton's gross pay is take-home pay. To find the percentage of Colton's gross pay that is take-home pay, we need to divide his net pay by his gross pay and then multiply by 100 to convert the resulting decimal to a percentage.

To find the percentage of Colton's gross pay that is take-home pay, we need to divide his net pay by his gross pay and multiply the resulting decimal by 100 to express it as a percentage. Colton's gross pay is $1421.50 and his net pay is $973.48. Dividing the net pay by the gross pay gives a result of 0.685, or 68.5% when converted to a percentage. This means that 68.5% of Colton's gross pay is take-home pay, or the amount of money that he receives after deductions are made. Therefore, Colton's take-home pay is $973.48, which is 68.5% of his gross pay.

Answer:

105°

Step-by-step explanation:

The given angles are vertical and congruent , then

8x - 21 = 6x + 3 ( subtract 6x from both sides )

2x - 21 = 3 ( add 21 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Then

6x + 3 = 6(12) + 3 = 72 + 3 = 75°

Supplementary angles sum to 180° , thus

supplementary angle = 180° - 75° = 105°

Researchers try to gain insight into the characteristics of a sample population by examining a sample of the population.

A sample is a subset of individuals or units taken from a larger population. Researchers use sampling methods to select a representative group of individuals from the population they are interested in studying. By studying the sample, researchers can make inferences and draw conclusions about the characteristics, behaviors, or trends that may exist within the entire population.

The goal of sampling is to obtain a sample that accurately represents the population in terms of its relevant characteristics. Researchers carefully select their samples to ensure that they are representative and minimize bias. This allows them to generalize the findings from the sample to the larger population with a certain level of confidence.

By examining a sample, researchers can collect data, analyze patterns, and draw conclusions about the population as a whole. This approach is more feasible and practical than attempting to study the entire population, especially when the population is large or geographically dispersed.

Therefore, researchers use samples to gain insight into the characteristics of a population, making option d. "Sample" the correct answer.

The diameter of the Ferris wheel is equal to 95 ft.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have a function that models the height of a seat on a Ferris wheel after [t] minutes.

We have the following function -

f(t) = 95 cos(π/10)t

The diameter of the Ferris wheel would be the maximum height reached by the wheel. We have -

f(t) = 95 cos[(π/10)t]

df/dt = 95 x - sin[(π/10)t] x (π/10)

df/dt = -(95π/10) sin[(π/10)t]

For maximum height -

df/dt = 0

- (95π/10) sin[(π/10)t] = 0

sin[(π/10)t] = 0

sin[(π/10)t] = sin (0)

(π/10)t = 0

t = 0

Put t = 0, in f(t) = 95 cos[(π/10)t], we get -

f(max) = 95 cos(0) = 95 ft

Therefore, the diameter of the Ferris wheel is equal to 95 ft.

Answer:

The area of the new triangle is 180 m²

Step-by-step explanation:

let the height of the triangle = h

let the base of the triangle = b

The area of right triangle is given by;

A =  ¹/₂bh

20 = ¹/₂bh

If we multiple each side of the triangle by 3, the new area of the triangle will be as follows;

A= ¹/₂(3b)(3h)

A = ¹/₂(9) (bh)

A = 9(¹/₂bh)

A = 9(20)

A = 180 m²

Therefore, the area of the new triangle is 180 m²

Answer: D

Step-by-step explanation:

First we need to find the slope between the two points:

(y2-y1) / (x2-x1)

= -3 - 5  /  -7 - 5

= -8 / -12

=  2 / 3

We have the slope. Now we need to find the y intercept.

y = (2 / 3)x + b

Using one of the points, I will be using (-7,-3)

-3 = (2 / 3)-7 + b

-3 = -14 / 3 + b

b = -3 + 14 / 3

b = 5 / 3

Therefore, the equation will be:

y = (2 / 3)x + (5 / 3)

Given dimensions of rectangular design:

Width = w1 = 5 in

Length = l1 = 8 in

As mentioned, Katie uses a copy machine to enlarge her rectangular design. Therefore,

new width = w2 = 10 in

new length = l2 = x in

Katie creates a large copy of the original design. Therefore, the ratio of length to width must remain the same (as the original design). So, we can write as:

Now, let's put all the values in the equation

or

x = 16

Therefore, the new length would be 16.

Equation B has the square of n (n^2) on the left side but not on the right side.  Thus this is not an identity.

Answer:

9,125 L

Step-by-step explanation:

The computation of the milk that can a farmer would get from a cow in one year is shown below:

As in the table it is shown that

In 2 days, the amount of milk is 50 L

In 7 days, the amount of milk is 175

and so on

So if we can see that the number of days should be multiplied by 25 to get the liters

So for 365 days, the milk would be

= 365 days × 25

= 9,125 L

When analyzing categorical data, it is often useful to examine the relationship between two variables. Crosstabs, or contingency tables, are commonly used to display the counts of observations in each combination of the two variables. However, these raw counts can be difficult to interpret, especially if the totals for each variable are different.
By transforming the counts into percentages of row or column totals, we can better understand the patterns and relationships in the data. Percentages allow us to compare the proportions of one variable within each category of the other variable, regardless of the total number of observations. This can help us identify any trends or patterns in the data that may not be immediately apparent from the raw counts.

For example, suppose we have a crosstab of gender and favorite color. The raw counts may show that more females than males prefer blue, but it's difficult to know if this difference is meaningful without knowing the total number of males and females in the sample. By transforming the counts to percentages of row totals, we can see that 40% of females prefer blue, while only 30% of males do. This suggests that there may be a relationship between gender and favorite color.

Overall, transforming raw counts into percentages of row or column totals can help us better understand the relationship between two categorical variables, especially when the totals are different.

8 hours shift because you count from 7 am to 3pm

The total number of hours between the 7 am and 3 pm shift is 8 hours.

What is meant by the hour?

Depending on the speed of the Earth's rotation, an hour is a measure of time that is traditionally calculated as 1/24  of a day and scientifically estimated to last between 3,599 and 3,601 seconds. There are 24 hours in a day and 60 minutes in an hour.

The 24-hour day is divided into two sections, a.m. and p.m., according to the 12-hour clock time convention. Latin terminology for the hours of the day, AM and PM, are commonly employed. The abbreviations AM and PM stand for Ante meridiem and Post meridiem, respectively, which indicate before noon or midday and afternoon or midday. AM is used to denote the first 12-hour period, which runs from midnight to noon, and PM is used to denote the following 12-hour period, which runs from noon to midnight.

From 7 am to 12 pm, the number of hours = 5

From 12 pm to 3 pm, the number of hours = 3

Therefore the total number of hours between the 7 am and 3 pm shift is (3+5) = 8 hours.
