Step-by-step explanation:
First, we need to calculate the cost of purchasing new seats for all the buses. The company has 13 buses and each bus has 28 seats, so the total number of seats to be replaced is 13 * 28 = 364 seats. The cost of purchasing each seat is $89.40, so the total cost of purchasing new seats for all the buses is 364 * $89.40 = $32,610.40.
Next, we need to calculate the cost of installing new seats for all the buses. The cost of installing each seat is $31.70, so the total cost of installing new seats for all the buses is 364 * $31.70 = $11,625.80.
Finally, we need to add the cost of purchasing and installing new seats to get the total cost the company will pay. The total cost of purchasing new seats is $32,610.40 and the total cost of installing new seats is $11,625.80, so the total cost the company will pay is $32,610.40 + $11,625.80 = $44,236.20.

Shen rented a truck for one day. There was a base fee $18.95 and there was an additional charge of 83 cents for each mile driven. Shen had to pay $213.17 when he returned the truck. For how many miles did he drive the truck
Answer:
234 miles
Step-by-step explanation:
Lets set the variable 'n' as the number of miles driven. We can set up the following equation:
18.95 + 0.83n = 213.17
Now, all we have to do is solve it. We can get 0.83n = 194.22, so n = 194.22/0.83 = 234 miles
(a) The perimeter of a rectangular field is 350 m.
If the width of the field is 79 m, what is its length?
Answer: 96 m.
Step-by-step explanation: Let's call the length of the rectangular field "L".
We know the perimeter of the field is equal to the sum of all its sides, so:
350 = 2L + 2 * 79
Expanding the right side, we have:
350 = 2L + 158
Subtracting 158 from both sides:
192 = 2L
Dividing both sides by 2:
L = 96 m
So the length of the rectangular field is 96 m.

The subtotal for Abdiel's takeout order is $21.50. What will Abdiel's total be if he uses a coupon for 10% off the subtotal and leaves a 20% tip before the discount? (2 points)
$22.15
$27.95
$23.22
$23.65
Answer: To calculate the total, we need to first calculate the discount and then the tip.
First, calculate the discount: $21.50 x 10% = $2.15
Then, subtract the discount from the subtotal: $21.50 - $2.15 = $19.35
Next, calculate the tip: $19.35 x 20% = $3.87
Finally, add the tip to the subtotal after the discount to find the total: $19.35 + $3.87 = $23.22
Therefore, Abdiel's total would be $23.22 if he uses a coupon for 10% off the subtotal and leaves a 20% tip before the discount.

How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The parameters for this problem are given as follows:
[tex]\mu = 10, \sigma = 2.7[/tex]
The proportion over 15.5 pounds is one subtracted by the p-value of Z when X = 15.5, hence:
Z = (15.5 - 10)/2.7
Z = 2.04
Z = 2.04 has a p-value of 0.9793.
1 - 0.9793 = 0.0207.
The proportion under 11.9 pounds is the p-value of Z when X = 11.9, hence:
Z = (11.9 - 10)/2.7
Z = 0.7
Z = 0.7 has a p-value of 0.7580.
The proportion between is the subtraction of the p-values, hence:
0.9793 - 0.7580 = 0.2213 = 22.13%.

What are composite functions?Composite functions are mathematical functions that are formed by taking the output of one function and using it as the input for another function.
(a) To find fog(x), we need to evaluate g(f(x)).
Since function f(x) = 2x, we have:
g(f(x)) = g(2x) = (2x)² = 4x²
Therefore, fog(x) = 4x².
(b) To find gof(x), we need to evaluate f(g(x)).
Since g(x) = x², we have:
f(g(x)) = f(x²) = 2(x²) = 2x²
Therefore, gof(x) = 2x².
(c) To find gog(x), we need to evaluate g(g(x)).
Since function g(x) = x², we have:
g(g(x)) = g(x²) = (x²)² = x⁴

$540 is invested in an account earning 9.1% interest (APR), compounded
continuously. Write a function showing the value of the account after t years, where
the annual growth rate can be found from a constant in the function. Round all
coefficients in the function to four decimal places. Also, determine the percentage of
growth per year (APY), to the nearest hundredth of a percent.
Answer: The formula for continuously compounded interest is given by:
A = P * e^(rt)
Where:
A = the final account balance
P = the initial investment (principal)
r = the annual growth rate as a decimal
t = the number of years the investment is held
In this case, P = 540, r = 0.091 and t = t years.
So, the function showing the value of the account after t years is:
A = 540 * e^(0.091t)
To find the percentage of growth per year (APY), we can use the formula:
APY = (e^r - 1) * 100
Substituting r = 0.091, we find:
APY = (e^0.091 - 1) * 100 = 9.56%
So, the APY is approximately 9.56%, to the nearest hundredth of a percent.

A truck with 0.300 m radius tires travels at 28.0 m/s.
a) What is the angular velocity of the rotating tires in radians per second?
b) What is this in revolutions per minute?
Answer:
Angular velocity = 93.33 radians/second
Revolutions per minute = 1,782.51 revolutions per minute
Step-by-step explanation:
The relation between angular velocity, ω and linear velocity, v is given by the equation
[tex]\omega = \dfrac{v}{r}[/tex]
where ω is in radians per second
v = m/s
and r is the radius (m) of the circular motion, in this case, the radius of the tire
Given v = 28 m/s and r = 0.300 m
we get
[tex]\omega = \dfrac{28 \;m/s}{0.3\;m} = 93.33 \;radians/second[/tex]
Since 2π radians make a full revolution, 93.33 radians/sec = 93.33 ÷ 2π = 29.708 revolutions per second
To get the revolutions per minute, multiply this by 60 since there are 60 seconds to a minute:
29.708 x 60 = 1,782.51 revolutions per minute

3) Destiny has 800 gallons of water in her pool and is adding water at a rate of 25 gallons per minute. Jabez only has 20 gallons of water in his pool but water is being added at a rate of 45 gallons per minute. How long before both pools have the same amount of water? answer fast pls
Answer: After 39 minutes, both pools will have the same amount of water.
Step-by-step explanation:
Let's call the number of minutes elapsed t. Then the amount of water in Destiny's pool after t minutes is 800 + 25t gallons, and the amount of water in Jabez's pool after t minutes is 20 + 45t gallons.
We want to find the time t at which the two pools have the same amount of water, so we set their amounts equal:
800 + 25t = 20 + 45t
Subtracting 20 from both sides of the equation:
780 + 25t = 45t
Subtracting 25t from both sides of the equation:
780 = 20t
Dividing both sides of the equation by 20:
39 = t
So, after 39 minutes, both pools will have the same amount of water.

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
a)
The initial number of cards Stacy has = 3 cards
The number of cards she gets per week = 2 cards
So , the total number of cards after x weeks = 2x cards
And , the total number of cards = initial number of cards + number of cards after x weeks
Substituting the values in the equation , we get
y = 2x + 3
b)
The first point is P ( 3 , 9 )
The second point is Q ( -3 , -9 )
So , the equation of line is y = 3x
when x = 3 , y = 9
c)
f = p + 3/2 be equation (1)
when p = 1
f = 1 + 3/2
f = 5/2
when p = 2
f = 2 + 3/2
f = 7/2
when p = 3
f = 3 + 3/2
f = 9/2
d)
The equation of line is y = 3x and the graph is plotted with the points P ( 1 , 3 ) and Q ( 2 , 6 )
e)
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 0 , 1 )
Let the second point be Q ( 2 , 5 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 5 - 1 ) / 2
Slope m = 2
Now , the equation of line is y - y₁ = m ( x - x₁ )
y - 1 = 2 ( x - 0 )
y - 1 = 2x
Adding 1 on both sides of the equation , we get
y = 2x + 1
Now , when the number of years = 4
y = 2 ( 4 ) + 1
y = 9 dogs
Hence , the equation is solved

A wine maker can make 14 bottles of wine with 80 pounds of grapes. If the wine maker picks 625 pounds of grapes, how many bottles of wine can be made? round to the nearest whole bottle.
Answer:First, we can calculate how many bottles of wine can be made per pound of grapes:
14 bottles / 80 pounds = 0.175 bottles / pound
Next, we can multiply this number by the number of pounds of grapes the wine maker has to find the total number of bottles of wine that can be made:
0.175 bottles / pound * 625 pounds = 110.31 bottles
Rounding to the nearest whole bottle, we find that the wine maker can make 110 bottles of wine with 625 pounds of grapes.
Step-by-step explanation:
Kai bought his younger sister, Loni, a sticker book and 12 stickers. Each week he gives his sister two new stickers. Let w represent the number of weeks that Loni collects stickers, and let s represent the total number of stickers she has collected. a. Determine the independent and dependent variables. The number of weeks, w, is the ? variable. The total number of stickers, s, is the ? variable.
Answer:
w = independent variables = dependent variable======================================================
Reason:
The number of weeks can be any number from the set {0,1,2,3,...} so we say that this value is independent. It does not depend on the number of stickers.
But the number of stickers does depend on the number of weeks. As w changes, so does the value of 's'.
The equation would be: s = 2w+12
Plug in w = 0 to find that s = 12. This is the starting amount of stickers.Plug in w = 1 to find s = 14. This is the number of stickers after 1 week.Plug in w = 2 to find s = 16. This is the number of stickers after 2 weeks.And so on. Each time 'w' goes up by 1, 's' goes up by 2.

What is a survey?A quantitative survey uses statistics to gather facts and figures. It's most frequently utilized to support or refute a conclusion you may have reached after conducting qualitative research.
A survey may be qualitative, quantitative, or a combination of the two. A quantitative survey is one that uses a questionnaire with scaleable responses. If your survey has descriptive questions with in-depth answers then it is a qualitative survey. Your survey is a mixed-method survey if it uses both of them.
