If a car tire has a radius of 13 inches, how many revolutions will the tire make in one mile?

Answer:

75 hairs/ day =  525 hairs / week

Step-by-step explanation:

so your base question for this is 75 hairs/ day =? h/ week. how? if the dog is losing 75 hairs per day, then you would do 75 x 7 becuase there are 7 days in a week. the answer to that would give you how many hairs the dog was losing per week. (see attached image for reference)

Answer:

Option C or 56.25×πcm^2

Step-by-step explanation:

The formula to find the circumference of a circle is P=2×π×r.

The formula to find the area of a circle is A=π×r^2.

Step 1: Find the radius by expanding your circumference answer to get the entire formula. In this case 15π=2×π×7.5 Look familiar? You have found the radius!

Step 2: Put the radius in the formula to find the area. Since this answer is not looking for a specific number that's all you have to do. In this case, A=π×7.5^2. Or A=π×56.25.

Step 3: You have the answer. Hope this helps

The answer to the nearest meter is 63 meters.

The calculation can be calculated as follows :

The first step is to convert 205.5 feet to meters

1 foot = 0.305 meter

= 205.3 x 0.305

= 62.6775 meters

The next step is to round the answer to the nearest meter

62.6775 meters

= 63 meters

Hence, the conversion 205.5 feet to meters is 63 meters.

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Answer: the mean is 20

Explanation: To find the mean, you add all the numbers of the data set. (21+17+21+25+23+13) = 120. Then when you have that answer, you divide it by how many numbers are in the data set (6 numbers). So then it would be 120 divided by 6 = 20.

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Step-by-step explanation:Much is usually anticipated about the fierce and decidedly bloody clashes between Wolverine and Victor Creed, the man known as Sabretooth, even though these men are arguably two sides of the same coin. Each of them has deadly claws that rend and draw blood; each has a generous amount of fear and intimidation working for them; each has a healing factor that prevents them from being mortally wounded (eventually reaching preposterous levels of effectiveness); and each has killed and will kill if the situation calls for it. Yet there are differences, as well: Logan's skeleton, as well as his claws, are made of the unbreakable metal known as adamantium; and while there have often been instances where he's been shown to be merciless, he's not nearly as sadistic as Creed, who will not hesitate to kill even when there is no reason for it. Perhaps the difference that keeps us engaged, however, is the fact

Answer:

Equation: m=21(p)

Difference: $5

Step-by-step explanation:

To solve this, we first need to figure out an equation for Company R.

We know that Company S's equation is m=26(p). this means that the amount reimbursed is 26 times the amount of aluminum returned.

210/10=21

Company R's equation is m=21(p). We know this because throughout the table, the amount reimbursed is always 21 times more than the amount of aluminum returned.

Now that we have two equations, we can solve. 26-21=5.

Therefore, the difference between the amount reimbursed per pound is $5. (As long as there is not another variable, this should be the answer for part b)

Answer:

Step-by-step explanation:

You divide the amount of money it all costs to the number of plushies they are selling it for.

A: 34.08/12 = $2.84 each

B: 42.90/15 = $2.86 each

C: 50.58/18 = $2.81 each

So C has the least amount of money spent for a greater amount of plushies so C would be the Best Buy.

Step-by-step explanation:

Answer: We can find the equation of a plane in point-normal form, which is given by:

Ax + By + Cz + D = 0

where (A, B, C) is the normal vector to the plane and (x, y, z) are the coordinates of any point on the plane, and D is a constant.

To find the normal vector, we can use the cross product of two vectors that lie on the plane. A convenient choice for these vectors is the direction vector of the line, which is given by:

v = <2-3, -1-4, 5-(-1)> = < -1, -5, 6 >

The normal vector to the plane is given by the cross product of the direction vector of the line and the vector pointing from any point on the line to the point (2,-3,1). Let's call this vector v2 = <2-3, -3-4, 1-(-1)> = < -1, -7, 2>

So the normal vector is given by:

n = v x v2 = ( -52 + 6-7)i + (6*-1 - -12)j + (-1-7 - -5*2)k = (14)i + (-7)j + (-11)k

Given that the point (2,-3,1) lies on the plane, we can substitute these values in the point-normal form equation:

A2 + B-3 + C*1 + D = 0

-142 + -7-3 + -11*1 + D = 0

-28 - 21 - 11 + D = 0

D = 58

So the equation of the plane is :

14x - 7y - 11z + 58 = 0

This is the equation that represents the plane that passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5)
