3 10 in . = 7 8 mi . what is the unit rate
Answers
Answer: (3/10) in = (7/8) mi
1 in = (7/8) mi ÷ (3/10)
= 7/8 * (10/3) = 70/24
1 in = (70/24) mi
It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.

Lynn took a taxicab from the office to the airport. She paid $4 per mile plus a $6 flat fee. Her total cost was $66. How many miles was the trip?
Answers
Answer:
12
Step-by-step explanation:
Answer:
15 miles
Step-by-step explanation:
To answer this question, we must break up the question. First, we know Lynn paid a total of $66 for the trip. She had to pay $4 per mile, and the flat fee was $6, meaning that no matter how many miles they rode, she had to pay an extra $6 on top of that. So, we can subtract the total cost by the flat fee:
66 - 6 = 60
Then, we divide that number by the amount it costs to ride each mile, which is 4:
60 / 4 = 15
So, Lynn's trip was 15 miles

How do numbers help us predict the ebbs and flows in our lives? Think about things like circadian rhythms.
Answers
Numbers play a crucial role in helping us predict the ebbs and flows in our lives. They are used to measure and quantify patterns and cycles that occur in our daily lives, such as circadian rhythms.
Circadian rhythms are the physical, mental, and behavioral changes that follow a 24-hour cycle, responding primarily to light and darkness in an organism's environment. Numbers help us measure and track these rhythms, allowing us to predict when we will feel awake or sleepy, hungry or full, and so on.
For example, we know that the average human circadian rhythm is 24.2 hours, and that our bodies produce the hormone melatonin at night to help us sleep. By measuring and tracking these numbers, we can predict when we will feel tired and need to sleep, and when we will feel awake and alert.
Numbers also help us predict other patterns in our lives, such as our menstrual cycles, the best times to exercise, and when we are most likely to get sick. By tracking and measuring these numbers, we can better understand and predict the ebbs and flows in our lives and make more informed decisions about our health and well-being.

Determine whether the given value is a statistic or a parameter the number of birds in diffferent regions
Answers
In the context of statistics, a statistic refers to a numerical value that is calculated from a sample of data, while a parameter refers to a numerical value that describes a population.
In the given scenario, the number of birds in different regions can be considered as either a statistic or a parameter depending on the context in which it is used.
If the number of birds is obtained by counting the birds in a specific region and then calculating summary measures such as the mean, median, or standard deviation based on that sample, then it would be considered a statistic. This is because the data is collected from a subset (sample) of the entire population of birds.
On the other hand, if the number of birds represents the total count or an average count across all regions without any sampling involved, then it would be considered a parameter. In this case, the value represents a characteristic of the entire population of birds in different regions.
It is important to note that whether the number of birds is considered a statistic or a parameter depends on how the data is collected and analyzed.
If multiple samples are taken from different regions and statistical inference techniques are used to make inferences about the entire population, then it would be appropriate to consider it as a statistic. However, if the data represents a complete count or an average across all regions without any sampling involved, then it would be considered a parameter.

an art gallery is selling replicas of some famous artworks. a copy of the artwork is dilated by a scale factor of 13 to create a replica of the original piece. if the area of some original artwork was 12 square feet, what will be the area of the replica? enter the answer in the box, rounded to the nearest hundredth.
Answers
The area of the replica is approximately 1.33 square feet, Rounded to the nearest hundredth.
If the original artwork has an area of 12 square feet, then a replica created by dilating the original by a scale factor of 1/3 will have an area that is (1/3)^2 = 1/9 of the original area. Therefore, the area of the replica will be:
12 square feet × 1/9 = 4/3 square feet ≈ 1.33 square feet
A scale factor is a multiplier that scales or resizes a shape, figure, or object. It is used to determine the size of a new shape or figure when it is scaled up or down by a certain factor. The scale factor can be expressed as a ratio, a fraction, or a decimal. For example, if a rectangle has a length of 10 units and a width of 5 units, and it is scaled up by a factor of 2, the new rectangle will have a length of 20 units and a width of 10 units. The scale factor, in this case, is 2.
Scale factors are commonly used in geometry, especially in transformations such as dilation, which involves scaling a shape by a certain factor without changing its shape. Scale factors can also be used in real-world applications such as maps, where a scale factor is used to represent the ratio between the distance on the map and the actual distance on the ground.

show that if λ is an eigenvalue of a and x is an eigenvector belonging to λ. show that for m ≥ 1, λ m is an eigenvalue of am and x is an eigenvector of am belonging to λ m.
Answers
If λ is an eigenvalue of matrix A and x is the corresponding eigenvector, then for any positive integer m, λ^m is an eigenvalue of A^m, and x is the corresponding eigenvector of A^m.
Let λ be an eigenvalue of matrix A with eigenvector x. This means that Ax = λx. Now, consider the matrix A^m, where m is a positive integer. By multiplying both sides of the eigenvector equation by A^(m-1), we have A^(m-1)Ax = A^(m-1)(λx), which simplifies to A^mx = λA^(m-1)x.
Since A^mx = (A^m)x and A^(m-1)x = λ^(m-1)x, we can rewrite the equation as (A^m)x = λ^(m-1)(Ax). Using the initial eigenvector equation Ax = λx, we have (A^m)x = λ^(m-1)(λx), which further simplifies to (A^m)x = λ^m x.
Therefore, we have shown that if λ is an eigenvalue of A with eigenvector x, then for any positive integer m, λ^m is an eigenvalue of A^m with the same eigenvector x. This result demonstrates the relationship between eigenvalues and matrix powers, illustrating that raising the matrix to a power corresponds to raising the eigenvalue to the same power while keeping the eigenvector unchanged.

Answer:
A) A history book about pirates that has at least one character about female pirates
Explanation:
A history book about pirates will probably have educated views on a female pirate's life, as it's purpose is to inform.
The article about a female pirate's three-times-great grandchildren will likely not be specific and unbiased enough to have an educated answer to our question.
A movie about a female pirate will likely be dramatized and not have adequately expert ideas on the pirate's life.
A how-to-be-a-pirate guide will not accurately portray a 1600-1800 pirate woman's life. Because it's aimed at young girls, this is not a reliable source either.

a. $593.60
b. $549.08
c. $578.38
Answers
If the Uptown bank lends $22200 at 6.9% , then the amount of each monthly payment is (d) $530.57 .
The amount that Uptown bank will lend is = $22200 ,
the rate is = 6.9% ,since it is compounded monthly ,
So , monthly rate is = 6.9%/12 = 0.00575 ,
the time for which the car is financed is = 48 months ,
So , to calculate the monthly payment, we can use the formula:
⇒ P = (PV × r)/(1 - (1 + r)⁻ⁿ)
Where P is monthly payment, PV is present value of loan, r = monthly interest rate, and n = number of payments.
In this case, PV = $22200, r = 6.9%/12 = 0.00575 (monthly interest rate), and n = 48.
Substituting these values in monthly payment formula, we get:
⇒ P = (22200×0.00575)/(1 - (1 + 0.00575)⁻⁴⁸)
⇒ P ≈ $530.57
Therefore, the monthly payment will be approximately $530.57 . The correct answer is (d) $530.57 .

Answers
The approximate area of the window that is not cleaned by the wiper is:
240 - 100.5 ≈ 139.5 square inches. Answer: \boxed{139.5}.
What is circle?
A circle is a geometric shape that consists of all points in a plane that are equidistant from a fixed point called the center.
To solve this problem, we need to find the area of the trapezoid and subtract the area of the semicircle.
The area of a trapezoid is given by the formula:
A = (a + b)h/2
where a and b are the lengths of the parallel sides, and h is the height (the perpendicular distance between the parallel sides).
In this case, we have:
a = 24 inches (the top parallel side)
b = 16 inches (the bottom parallel side)
h = 12 inches (the height)
Using the formula, we get:
A = (24 + 16) x 12/2
A = 240 square inches
The area of a semicircle is given by the formula:
A = πr²/2
where r is the radius of the circle.
In this case, the radius is half of the length of the wiper, so we have:
r = 16/2 = 8 inches
Using the formula, we get:
A = π(8²)/2
A ≈ 100.5 square inches
Therefore, the approximate area of the window that is not cleaned by the wiper is:
240 - 100.5 ≈ 139.5 square inches. Answer: \boxed{139.5}.

The sum of all the angles in a triangle is also 180°.
Let the missing angle be x°.
For the straight line:
x + 2x²+ 3x+ 6 = 180
x = 180 - (2x² + 3x + 6)
x = 180 - 2x² - 3x - 6
x = 174 - 2x² - 3x
For the missing angle in the triangle:
(174 - 2x² - 3x) + 8x + 3x² - 6x = 180
174 - 2x² - 3x + 8x + 3x² - 6x = 180
174 + x² - x = 180
x² - x + 174 - 180 = 0
x² - x - 6 = 0
(x + 2)(x - 3) = 0
x + 2 = 0 or x - 3 = 0
