Final answer:

πr typically represents an expression involving the mathematical constant π and the radius of a circle (r). In mathematics, this is commonly part of formulas to calculate properties of circles, such as area or circumference.

Explanation:

When you see πr in mathematics, it typically represents the expression involving the mathematical constant π (pi), which is the ratio of a circle's circumference to its diameter, and r, which stands for the radius of the circle.

The actual value of π is approximately 3.14, but it is an irrational number, meaning it extends to infinity without repeating. In many equations and formulas, πr could be part of a larger expression to calculate properties related to circles, such as the area or circumference.

For example, the formula for the circumference of a circle is 2πr, and the formula for the area of a circle is πr2. Without additional context, πr could be part of these or other mathematical expressions related to circles. It is not to be confused with the Greek letter rho, which can also be represented as p and is used in different ways in physics and other sciences.

After substituting the number of members into the equation and solving for the total cost, Elise's 5-member team's entry fee into the race is $25.

The total cost of entering a team into a 5-kilometer race can be modeled by the linear equation -2x + y = 15, where x is the number of members on the team and y is the total cost. To calculate the total cost for Elise's 5-member team, we need to substitute x = 5 into the equation and solve for y.

First, we multiply the number of members by the additional cost per member: 5 members × $2/member = $10. Then, we add the team entry fee to get the total cost: $15 (team entry) + $10 (members) = $25. Therefore, the total cost for Elise's team is $25.

Final answer:

To find the total cost for Elise's team of 5 members, substitute x=5 into the equation -2x + y = 15 and solve for y to get the total cost of $25.

Explanation:

The student's question involves finding out the total cost of entering a team in a 5-kilometer race with a given equation that models the costs based on the number of team members. The equation provided is: -2x + y = 15, where x is the number of members on the team, and y is the total cost. To find the total cost for Elise's team that has 5 members, we replace the variable x with the number 5 in the equation and solve for y:

-2(5) + y = 15

-10 + y = 15
y = 25

The total cost for Elise to enter a team with 5 members in the race is $25.

To find x, we need to solve the quadratic equation 5x^2 - 100 = 0 using the quadratic formula.

To find x, we need to solve the quadratic equation 5x^2 - 100 = 0 using the quadratic formula. The formula is x = (-b ± √(b^2 - 4ac)) / (2a), where a, b, and c are the coefficients of the quadratic equation.

In this case, a = 5, b = 0, and c = -100. Plugging these values into the quadratic formula, we get:

x = (-0 ± √(0^2 - 4 * 5 * -100)) / (2 * 5)

Simplifying further, we have:

x = (√2000) / 10

Therefore, x equals approximately ±14.14.

The question involves a mathematical reading rate scenario where Naoya calculates how much of a book he has left to read. Since the numbers provided are unrealistic, an example with plausible figures is used to illustrate the process of determining total reading time and daily reading goals.

The question deals with a reading rate calculation problem involving Naoya, who has read part of a book and wants to figure out how much more he needs to read. We can figure out the total number of pages in the book by considering the pages he has read at the rate of 555,555 pages per hour over 444 hours, and adding the remaining 350,350,350 pages he has left to read. However, it appears there are typographical errors in the question with the repetition of numbers, which should likely be simplified to realistic figures before we can calculate the total number of pages in the book.To apply the concept efficiently, let's take an example with realistic numbers similar to the approach mentioned for Marta. Suppose Marta reads at a rate of 48 pages per hour and she needs to finish a 497-page novel. We divide the total page count (497) by her hourly rate (48 pages/hour) to find the total hours needed, which is approximately 10.35 hours or roughly 10 to 11 hours.

If Marta wishes to finish the novel over two weeks, she would divide her total reading time by the number of days she plans to read, ensuring she allocates enough time each day to reach her goal. Similar reading strategies can be applied whether balancing act, early bird, or taking the approach of reading a certain number of pages each day to make a larger task more doable.

To find the shortest distance from Robert's home to his office, we use the Pythagorean theorem with the distances traveled north and east to calculate the length of the hypotenuse, which is approximately 7.2 kilometers.

Robert leaves his home and drives 6 km due north and then 4 km due east. To determine the shortest distance from Robert's home to his office, we can use the Pythagorean theorem. This scenario forms a right-angled triangle where the two sides are the north-bound and east-bound legs of his journey, and the hypotenuse is the shortest distance.

Step 1: Label the lengths of the two sides adjacent to the right angle as 'a' and 'b', where 'a' is the 6 km north-bound leg and 'b' is the 4 km east-bound leg.

Step 2: Apply the Pythagorean theorem, which states that the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides:

c² = a² + b²

Step 3: Substitute the known values into the theorem:

c² = 6² + 4²

Step 4: Calculate the squares of the sides and sum them:

c² = 36 + 16

Step 5: Sum the squares gives us:

c² = 52

Step 6: Take the square root of both sides to find 'c':

c = √52

Step 7: Calculate the square root which approximately equals:

c = 7.2 km

Therefore, the shortest distance from Robert's home to his office is approximately 7.2 kilometers.

We have a coordinate plane that is placed over an empty lot. So you and your friend are set at that coordinate system, so I'll give you the representation of each statement and the distance that the snowball travels from your friend's hand to you.

1. You face the positive y-axis and your friend faces the negative y-axis. 

This statement is represented in Figure 1. So you are the Red square and your friend is the Blue one. The arrows upon the squares mean that you are facing the positive y-axis and your friend the negative one. 

2. You run 20 feet forward, then 15 feet to your right. At the same time, your friend runs 16 feet forward,  then 12 feet to her right.

This is shown in Figure 2. So, at the coordinate system, you move 20 feet upward and 15 feet to your right, that is, you walk from the origin to the point [tex]P_{1}(15,20)[/tex] first moving through the positive y-axis and next through the positive x-axis. On the other hand, your friend moves 16 feet downward and 12 feet to her right, that is, she walks from the origin to the point [tex]P_{2}(-12,-16)[/tex] first moving through the negative y-axis and next through the negative x-axis. 

3. She stops and hits you with a snowball.

This statement is represented in Figure 3. So the snowball has been drawn in gray. The line from your friend to you is the distance the snowball runs.

4. Distance the ball runs.

We can get this answer by using the Distance Formula, that is:

[tex]d=\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^2} \\ d=\sqrt{[15-(-12)]^{2}+[20-(-16)]^2} \\ \boxed{d=45ft}[/tex]

Answer:

Step-by-step explanation:

Final answer:

Among the options provided, only D.) 97 is a prime number because it only has two divisors: 1 and itself. All other options have more than two divisors and thus are not prime.

Explanation:

To determine which number is prime, we must recall that a prime number is a number that has only two distinct positive divisors: 1 and itself. Now, let's evaluate the options given:

A.) 49 is 7 times 7, so this is not a prime number.

B.) 27 is 3 times 9, hence this is not a prime number either.

C.) 14 is 2 times 7, which means it is not a prime number.

D.) 97 does not have any divisors other than 1 and itself, so it is a prime number.

So, the correct answer is D.) 97, since it fulfills the conditions for being a prime number.
