Find a formula for the number of seats sold if the ticket price is P dollars.
Answer:
(680 - P)/3
Step-by-step explanation:
A) Let x be equal to the number of seats and hence we can conclude that (160 - x) is equal to the number of seats after the increase in price.
Similarly, the increase in ticket price would be equal to (P - 200)
Due to the fact that for every $3 increase, the number of seats decrease by 1, the equation that links the change in the number of seats to the change in ticket price is;
P - 200 = 3(160 - x)
P = 3(160 - x) + 200
Making x the subject;
P = 480 - 3x + 200
P = 680 - 3x
3x = 680 - P
x = (680 - P)/3
The height of a tree at time t is given by h(t) = 2t + 3, where h represents the height in inches and t represents the number of months. Identify the independent and the dependent variables.
Answer:
Step-by-step explanation:
You see that 't' is the 'argument' or 'input' to h: h(t). It is always safe to assume that t is the independent variable and h is the depend
Write a polynomial f(x)that satisfies the given conditions,
Polynomial of lowest degree with zeros of - 4 (multiplety 1), 3 (multiplicly 3), and with f(0)= 216,
Answer:
[tex]\boxed{\sf \ \ \ -2(x+4)(x-3)^3 \ \ \ }[/tex]
Step-by-step explanation:
Hello,
let's note k a real, we can write the polynomial as
[tex]k(x-(-4))^1(x-3)^3=k(x+4)(x-3)^3[/tex]
and we know that f(0)=216 so
[tex]216=k(0+4)(0-3)^3=k*4*(-1)^3*3^3=-27*4*k=-108k\\\\<=> k=-\dfrac{216}{108}=-2[/tex]
So the solution is
[tex]-2(x+4)(x-3)^3[/tex]

a man bought second hand bicycle for rs 1120 and spend rs160 to repair it. he sold it for rs1344, find his profit or loss percent
Answer:
5 %Solution,
Total Cost price (CP) = Rs 1120 + Rs 160
= Rs 1280
Selling Price (SP) = Rs 1344
Here,
SP > CP , so he made profit.
Amount of profit = SP - CP
= Rs 1344 - Rs 1280
= Rs 64
Now, finding the profit percent,
Profit %=[tex] \frac{profit \: }{cp} \times 100 \: percent[/tex]
[tex] \frac{64}{1280} \times 100 \: percent[/tex]
[tex]5 \: percent[/tex]
Profit percent = 5%

Answer:
1080
Step-by-step explanation:
Multiply the value by 1440. Hope this helps!
Answer:
1080 minutes
Step-by-step explanation:
In a day there are 24 hrs so first we have to find 1 quarter of a day which will be;
24hrs ÷ 4 = 6hrs
The question says 3 quarters so you multiply 6hrs by 3
6hrs * 3 = 18hrs
Now will use proportion to answer the rest which is as follows.
If 1hr = 60 minutes,
then 18hrs = ? minutes
[tex]\frac{18}{1} * 60mins[/tex]
=1080 minutes.
Hope this will help.

A student builds unifix cube towers to represent the ages of the five children in her family. She places them in order from smallest to largest. She removes the shortest and tallest tower then removes the next shortest and tallest tower. The tower in the middle is remaining. This student has just found which average?
Mode
Mean
Range
Answer:
Mode
Step-by-step explanation:
The answer is Mode. Mode is basically a number or data item that appears most frequently in a data set. First lets see how we find Mode. To find the Mode in the data set, first the numbers or data items are placed in order. Then it is counted that how many times each number appears. A number or data item that appears most frequently is the mode.
So lets a student builds unifix cube towers to represent the ages of the five children as following:
3 1 2 2 4
Now the student first places them in order from smallest to largest
1 2 2 3 4
Now she removes the shortest and tallest tower. Shortest is 1 and tallest is having 4 cubes. After removal of shortest and tallest tower:
2 2 3
Then removes the next shortest and tallest tower. Now the shortest tower has 2 cubes and tallest has 3 cubes. After removal of shortest and tallest tower:
2
The tower in the middle is remaining i.e. 2
So as you can see the most frequently occurring from 1 2 2 3 4 is also 2 as it appears twice. So that means student has found Mode. Although the same method is used to find the median too but here the most appropriate option is Mode. Mean is the way to find the average but it is computed by adding the numbers in the data set with the total size of data. So its not an appropriate option because the method that the student followed does not match with the method to compute mean. Also range is not a valid option because range finds the difference of the largest and smallest number and the method that student used is different from the method to compute range. If we compute the difference between largest and smallest number we get 3.

The probability that Stu buys a sandwich is 0.5.
The probability that Stu gets the bus is 0.7.
Assuming the events are independent, what is the probability that Stu buys a sandwich and gets the bus?
Answer:
probability that Stu buys a sandwich and gets the bus = 0.35
Step-by-step explanation:
Probability of success of two independent events is the product of the respective probabilities, i.e. the multiplication rule.
P(Sandwich) = P(S) = 0.5
P(Bus) = P(B) = 0.7
Assuming the events are independent,
probability that Stu buys a sandwich and gets the bus
= P(SB) = P(S)*P(B) = 0.5*0.7 = 0.35
Answer: 0.35
Step-by-step explanation:
First there is a 50% chance, or a 0.5 chance that Stu gets a sandwich. Then, ignoring the other .5, there is a .7 chance that he makes the bus. Thus, 1/2 of .7 is 0.35.

5z + 3z= 8z
-3y + 8z
The expression 2x − 2y + 5z − 2x − y + 3z is simplified as − 3y + 8z.
What is simplification?Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The expression is given below.
⇒ 2x − 2y + 5z − 2x − y + 3z
Simplify the expression, then we have
⇒ 2x − 2y + 5z − 2x − y + 3z
⇒ 2x − 2x − 2y − y + 5z + 3z
⇒ 0 − 3y + 8z
⇒ − 3y + 8z
The expression 2x − 2y + 5z − 2x − y + 3z is simplified as − 3y + 8z.

Jerry is paving the parking spot shown in the attached file below.
It costs $ 50 to pave each square meter. Find the cost to pave the parking spot [tex]6 \dfrac{1}{4}\ m[/tex].
Answer:
$1250
Step-by-step explanation:
From the image attached below;
The paving of Jerry around the parking spot assume a shape of parallelogram.
However, in order to find the cost to pave the parking spot, we need to first determine the area of the assume shape of the parking spot (i.e parallelogram)
Area of a parallelogram = Base × height
where;
the base = 4m
the height = [tex]6 \dfrac{1}{4}\ m[/tex]
Area of a parallelogram = [tex]4 \times 6 \dfrac{1}{4}[/tex]
Area of a parallelogram = [tex]4 \times \dfrac{25}{4}[/tex]
Area of a parallelogram = 25 m²
Since it cost $50 to pave 1 square meter;
∴
The cost to pave 25 m² area of the parking spot is
= 25 × 50
= $1250
Answer:
1250
Step-by-step explanation:
The parking space is in the shape of a parallelogram, so to find the area needed to pave it, you will use the formula for finding area of a parallelogram.
A = 4 x 6 1/4
A = 25 square meters
You will pave 25 square meters.
25 x 50 = 1250

The two cones are similar. (a) Write down the value of l. (b) When full, the larger cone contains 172 cm3 of water. How much water does the smaller cone contain when it isfull?
Answer/Step-by-step explanation:
a. Since both cones, as shown in the figure attached below, are similar, 11/8 = l/4
Cross multiply to find l
4*11 = 8*l
44 = 8l
l = 44/8
l = 5.5cm
b. Given the slant height and diameter of cone, volume of cone can be calculated using the formula ⅓πr²*√(l² - r²)
Where, r = diameter ÷ 2 = 4/2 = 2cm
l = 5.5cm
Volume of smaller cone = ⅓*3.142*2²*√(5.5² - 2²)
= ⅓*3.142*4*√30.25 - 4)
= ⅓*12.568*√26.25
= ⅓*12.568*5.124
= 64.40/3
Volume of small cone ≈ 21.5 cm³

There are an infinite number of vector and parametric equations for a given plane. Why is the scalar equation of a given plane unique?
Answer:
The answer is below
Step-by-step explanation:
When you refer to a normal vector you mean the form a*x + b*y + c*z = d, if that's the case then it's not unique in the nose because it gives you its normal vector. Taking into account that uniqueness only supports multiplicative constants, which means that you can multiply the equation with whatever you want, that is, it remains the same
