A. 1/10
B. 1/5
C. 2/5
D. 2/15
E. 3/10
Final answer:
The ratio of the cost of 6 pairs of canvas shoes to the cost of 3 pairs of leather shoes is D. 2/5.
Explanation:
To find the ratio of the cost of 6 pairs of canvas shoes to the cost of 3 pairs of leather shoes, we need to calculate the total cost of each option.
For 6 pairs of canvas shoes, the cost is $7 per pair, so the total cost is 6 x $7 = $42.
For 3 pairs of leather shoes, the cost is $35 per pair, so the total cost is 3 x $35 = $105.
Therefore, the ratio is $42 : $105, which simplifies to 2/5.

Step-by-step explanation:
Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their environment. The formula is Upper T equals 50 plus StartFraction Upper N minus 40 Over 4 EndFractionT=50+ N−40 4, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If Nequals=9898, find the temperature in degrees Fahrenheit, T.
The temperature in degrees Fahrenheit, T is 68°F.
Dolbear's law states that the number of chirps per minute that a snowy tree cricket makes is related to the air temperature in degrees Fahrenheit by the following formula:
T = 50 + (N - 40)/4
where:
T is the temperature in degrees Fahrenheit
N is the number of chirps per minute
If N = 98, then the temperature is:
T = 50 + (98 - 40)/4 = 68 degrees Fahrenheit
So the answer is 68 degrees Fahrenheit.
Here is an explanation of the calculation:
We are given that N = 98 chirps per minute.
We substitute this value into the formula for Dolbear's law to get:
T = 50 + (98 - 40)/4 = 68 degrees Fahrenheit
Therefore, the temperature is 68 degrees Fahrenheit.
Here are some additional things to consider:
The number of chirps per minute that a snowy tree cricket makes is not always an accurate measure of the air temperature. The number of chirps can also be affected by other factors, such as the humidity and the time of day.
Dolbear's law is a simplified model of the relationship between the chirping rate of snowy tree crickets and the air temperature. The actual relationship is more complex and can be affected by a number of factors.

Step-by-step explanation:
Elise is entering a team into a 5-kilometer race. The cost for entry is $15 for a team and an additional $2 per member. The total cost can be modeled by the equation -2x + y = 15, where x is the number of members on the team and y is the total cost. What is the total cost if Elise has 5 members on her team?
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.
Explanation: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.

Naoya read a book cover to cover in a single session, at a rate of 555555 pages per hour. After 444 hours, he had 350350350 pages left to read.
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.

(π with an r next to it)
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.

What are the coordinates of point Q after this reflection
-8,3
-8,-3
-3,-8
8,3
The new coordinates of Q are (-8, -3).
When reflecting a point across the X-axis, the X-coordinate remains unchanged, while the Y-coordinate changes its sign. From the figure attached, we find coordinates of Q are (-8,3). Therefore:
The X-coordinate of Q remains as -8.The Y-coordinate of Q changes from 3 to -3.As a result, the coordinates of point Q after reflection along the X-axis will be (-8, -3).
Therefore, the new coordinates of point Q are (-8, -3).
A coordinate plane is placed over an empty lot. You and a friend stand back-to-back at the origin. You face the positive y-axis and your friend faces the negative y-axis. 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. She stops and hits you with a snowball.
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]
