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?
Answers
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.

Answers
Q = (x, y) = (- 8, 3)
A reflection of the figure on the x axis is given by the following rule:
(x, y) ----> (x, -y)
Applying the transformation:
(-8, 3) ---> (- 8, -3)
Answer:
the coordinates of point Q after this reflection are
-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).

D. 2/15
E. 3/10
Answers
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.

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]

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.

You want to know a pump's power output if it raises 2 tons of water 15 ft in 5 minutes.
PowerThe power is conveniently measured in horsepower. One horsepower is 33,000 ft·lb/minute.
Here, we have (2t · 2000 lb/t · 15 ft)/(5 min) = 12000 ft·lb/min
In terms of horsepower, that is ...
(12000 ft·lb/min) / (33000 ft·lb/min/hp) = 4/11 hp ≈ 0.364 hp
The power output of the pump is about 0.364 horsepower.

volume? Round to the nearest hundredth if necessary. Explain or show your work.
Answers
1470=113.04h
Divide both sides by 113.04:
1470/113.04 = 113.04h/113.04
13 ≈ h
The height of the cylinder is 13 inches. We know that the height of the cone is 1/2 the height of the cylinder; 1/2(13) = 6.5 inches. The formula for the volume of a cone is:
V=1/3πr²h
The cone and the cylinder have the same radius, and we now know that the height of the cone is 6.5. Substituting this information in we have:
V=1/3(3.14)(6²)(6.5) = 244.92 in³
The total volume of the cake would be the volume of the cylinder added to the volume of the cone:
1470+244.92 = 1714.92 in³.
The formula for the volume of a sphere, for the ball cake, is
V=4/3πr³. Using the radius of 3 we have:
V=4/3(3.14)(3³)=113.04 for the volume of the circus ball cake.
The formula for the area of the cone-shaped hat cake is V=1/3πr²h. We want it to have the same volume as the circus ball cake, and we know the radius is still 3:
113.04=1/3(3.14)(3²)h
This simplifies to
113.04=9.42h
Divide both sides by 9.42:
113.04/9.42 = 9.42h/9.42
The hat cake would have to have a height of 12 inches to have the same volume.

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.
Answers
We have then:
T = 50 + (N-40) / 4
We substitute the value of N = 98, we have then:
T = 50 + (98-40) / 4
T = 64.5 degrees Fahrenheit.
Answer:
the temperature in degrees Fahrenheit, T is:
T = 64.5 degrees Fahrenheit.
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.
