Kenny is ordering uniforms for both the girls' and boys' tennis clubs. He is ordering shirts for 43 players and two coaches at a total cost of $658.35. Additionally, he is ordering visors for each player at a total cost of $368.51. How much with each player pay for the shirt and visor?
Answer: 23.20 dollars
Cost for 1 shirt = $14.63
Cost for 1 visor = $8.57
Total = 14.63+8.57 = 23.20
==============================================================
Explanation:
s = cost of 1 shirt
v = cost of 1 visor
costs are in dollars
There are 43 players and 2 coaches that get a shirt. There are 43+2 = 45 people total that get a shirt. The amount of money spent on all the shirts is 45s because we multiply the number of people (45) with the cost per shirt (which is s). Set this equal to 658.35 and solve for s
45s = 658.35
s = 658.35/45
s = 14.63
Each shirt costs $14.63, and this is the amount each player should pay.
-------------------
Kenny is also ordering 43 visors. The total cost here is 368.51 dollars. This means the equation we need to solve is 43v = 368.51
Divide both sides by 43 to isolate v
43v = 368.51
v = 368.51/43
v = 8.57
Each visor costs $8.57, and this is the amount each player should pay.
-------------------
Add up the two costs we found and we get 14.63+8.57 = 23.20, which is the total cost each player must pay for both a shirt and a visor.

PLEASE I NEED HELP WITH MATH HW WITH EXPLANATION!!!
Question: Find the value of the varible
===================================================
Explanation:
For any triangle, the interior angles always add to 180
(angle1)+(angle2)+(angle3) = 180
(w) + (4w-6) + (w) = 180
(w+4w+w) - 6 = 180
6w - 6 = 180
6w - 6+6 = 180+6 .... adding 6 to both sides
6w = 186
6w/6 = 186/6 ..... divide both sides by 6
w = 31
------------------------------------
Extra info:
This value of w leads to
4w-6 = 4*31-6 = 118
The three angles of the triangle are: 31, 118, 31
Because we have two congruent angles, this means the triangle is isosceles. The sides opposite the congruent angles are the same length.
Water is flowing into a large spherical tank at a constant rate. Let V(t) be the volume of water in the tank and H(t) be the height of the water level at time t.
a) Give a physical interpretation of dV/dt and dH/dt.
b) Is dV/dt positive, negative, or zero when the tank is one-fourth full? Justify your answer.
c) Is dH/dt positive, negative, or zero when the tank is one-fourth full? Justify your answer.
Answer:
A) dV/dt = the rate of change of the given volume of water in the tank with respect to the time, t.
dH/dt = the rate of change of the height of the water in the tank with respect to the time
B) dV/dt is positive
C) dH/dt is positive
Step-by-step explanation:
We are given that;
V(t) is the volume of water in the tank and H(t) is the height of the water level at time t. Thus;
A) dV/dt = the rate of change of the given volume of water in the tank with respect to the time, t.
dH/dt = the rate of change of the height of the water in the tank with respect to the time
B) When the tank is one-fourth full, dV/dt is positive because the volume water in the tank is increasing with time.
C) when the tank is one-fourth full, dH/dt is positive because the height has increased from zero level to 0.25 times the height of the tank. Thus the height is increasing with time.

The answer is point C
Step-by-step explanation:
to make it easier to solve, think of it this way, point c and a are on the same "line",and point A is on the line under pi over 6. We know that pi over 12 is less than pi over 6, so that could potentially be the line that both points are on if that makes sense. We can also see that the real axis has the value of pi, and that point C is the value less than that. Also, point C is in the direction of where the negative "x values" would be

Ava, Cara, Emma, Lily, and Mia are to be seated together in a row. If Emma and Lily must sit next to each other, how many different ways can the five girls be seated
Answer:
48 ways
Step-by-step explanation:
Given
[tex]Girls = \{Ava, Cara, Emma, Lily, Mia\}[/tex]
[tex]Together= \{Emma, Lily\}[/tex]
Required
Determine the number of sitting arrangements
The number of girls are 5, of which 2 must be seated together.
First, Emma and Lily can be arranged in 2! ways
Next, we consider Emma and Lily as one, so there are (5 - 1) girls left to be arranged.
This can be done in (5 - 1)! ways
Total number of ways is then calculated as:
[tex]Ways = 2! * (5 - 1)![/tex]
[tex]Ways = 2! * 4![/tex]
[tex]Ways = 2 * 1 * 4 * 3 *2 * 1[/tex]
[tex]Ways = 48[/tex]
Hence, there are 48 ways
The possible ways in which Ava, Cara, Emma, Lily, and Mia are to be seated together in a row, while Emma and Lily sit next to each other are 48 ways.
Given to us;
Number of girls = {Ava, Cara, Emma, Lily, and Mia} = 5 girls,
Also, Emma and Lily must sit next to each other, therefore, considering them as a single person,
The choices we are left with = {Ava, Cara, Mia, (Emma, Lily)} = 4 person;
We know to calculate the number of ways people can sit is given by n! (n factorial), where n is the number of person. Thus,
different ways this 4 person can sit = n!
= 4!
= 4 x 3 x 2 x 1
= 24 ways
Further, as given in the question Emma and Lilly must sit together but they can change sits within themselves, So,
different ways Emma and Lilly can sit = n!
= 2!
= 2 x 1
= 2 ways
Therefore, the total number of ways all 5 girls can sit together in which Emma and Lilly will be always seated together,
Total ways all can sit together = 24 x 2
= 48 ways
Hence, the possible ways in which Ava, Cara, Emma, Lily, and Mia are to be seated together in a row, while Emma and Lily sit next to each other are 48 ways.

x = 40
Step-by-step explanation:
Sum of interior angle of an n-polygon = (n - 2)*180
The polygon given is pentagon with 5 sides.
Sum of the polygon = (5 - 2)*180 = 540°
Therefore, sum of all its interior angles would be:
5x + 150 + (3x - 30) + 70 + (2x - 50) = 540°
Solve for x
5x + 150 + 3x - 30 + 70 + 2x - 50 = 540
Collect like terms
5x + 3x + 2x + 150 - 30 + 70 - 59 = 540
10x + 140 = 540
10x = 540 - 140 (Subtraction property of equality)
10x = 400
x = 400/10 (division property of equality)
x = 40

How long will it take Scott to run 52 \text{ km}52 km52, start text, space, k, m, end text?
minutes
Answer:
Scott will take 221 minutes to run 52 km
Step-by-step explanation:
Speed
The speed of an object can be calculated with the formula:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where d is the distance traveled and t is the time taken.
Scott can run d=20 km in 85 minutes. Thus, his speed is:
[tex]\displaystyle v=\frac{20}{85}\ km/min[/tex]
Now he wants to know how many minutes it will take him to run d=52 km. Solving the formula for t:
[tex]\displaystyle t=\frac{d}{v}[/tex]
Since the speed has been already determined:
[tex]\displaystyle t=\frac{52}{\frac{20}{85}}[/tex]
Multiplying by the reciprocal of the denominator:
[tex]\displaystyle t=52*\frac{85}{20}[/tex]
t = 221 min
Scott will take 221 minutes to run 52 km

The correlation coefficient for the data is 0.93 and this can be determined by using the formula of the correlation coefficient.
Given :
The table shows data collected from 14 people.
A statistical measure of the strength of the relative movement between two variables is known as the correlation coefficient.
The formula of the correlation coefficient is given by:
[tex]\rm r = \dfrac{\sum (x_i-\bar{x})(y_i-\bar{y})}{\sqrt{\sum(x_i-\bar{x})^2\sum(y_i-\bar{y})^2} }[/tex]
where r is the correlation coefficient, [tex]\bar{x}[/tex] is the mean of the values of the x variable, [tex]x_i[/tex] values of the x-variable in the sample space, [tex]y_i[/tex] values of the y-variable in a sample space, and [tex]\bar{y}[/tex] is the mean of the values of the y-variable.
Now, from the attached table substitute the values of the known terms in the above formula.
[tex]\rm r = \dfrac{35.4464286}{\sqrt{(19.23214289)\times (76.08928571)} }[/tex]
Simplify the above expression.
[tex]\rm r = \dfrac{35.4464286}{38.25388889} }[/tex]
r = 0.93
