Singing star bitsy carlyle isnt as popular as she used to be at her latest concert she was only able to sell 910 tickets for a total of 15620 barely enough to pay her agent if regular seats cost 18.50 and mezzanine seats the only other option cost 16.25 how many mezzanine tickest were sold
The number of mezzanine tickets sold = 540
Total number of tickets sold = 910
Total number of tickets sold is the sum of the number of regular seats and the number of the mezzanine seats sold.
Let 'x' be the number of regular seats and 'y' be the number of mezzanine seats.
Then x + y = 910 ----------(1)
Cost of a regular seat = $ 18.50
So cost of x regular seats = 18.50x dollars
Cost of a mezzanine seat = $ 16.25
So cost of y mezzanine seats = 16.25y
Total amount of money she got by selling tickets = $ 15620
Therefore, 18.5x + 16.25y = 15620 ----------------(2)
Solve equations (1) and (2) for x and y.
Multiplying (1) with 18.5 throughout,
18.5x + 18.5y = 16835 ---------------(3)
Subtracting (2) from above equation (3), we get,
(18.5 - 16.25)y = 16835 - 15620
⇒ 2.25y = 1215
⇒ y = 1215/2.25
⇒ y = 540
Hence 540 mezzanine tickets were sold.

A kite of area 252 m² has one diagonal of length 9 m. Find the length of the other diagonal
Answer:
The other diagonal of the kite is 56 meters
Step-by-step explanation:
To find the length of the other diagonal you find to know the formula for finding the area of a kite which is A = (p×q)/2. It is given that the area is 252m² and one diagonal is 9m.
Place your given numbers in the formula for the area of the kite. With your numbers given the formula is 252 = (9q)/2 or alternatively 252 = (9p)/2Multiply both sides by 2 the reason being is that we are trying to islolate the unknown variable (weather it is p or q) so we are doing the inverse operation. So you will have 252 × 2 = (9p)/2×2 or (9q)/2×2. At the end of this step it is 504 = 9q or 504 = 9pDivide by 9 on both sides remember that the point is to islolate the variable. 504/9 = 9q/9 or 504/9 = 9p/9. The final answer is that your unknown diagonal (whether it was q or p) is 56 mwrite a function g whose graph is a reflection in the x axis of the graph of f(x)=|x|-5
please help
A function g whose graph is a reflection in the x axis of the graph of f(x) = |x| - 5 is g(x) = 5 - |x|
The question asks to find a function g, that is, g(x)
The graph of g(x) is a reflection in the x axis of the graph of f(x) = |x| - 5
Reflection of a function in the x-axis gives us
y = g(x) = - f(x)
=> g(x) = - ( |x| - 5 )
=> g(x) = - |x| + 5
=> g(x) = 5 - |x|
Therefore, using the concept of reflection of a function in x axis of the graph of the given function, we get a function g whose graph is a reflection in the x axis of the graph of f(x) = |x| - 5 as g(x) = 5 - |x|

Using the concept of ratio the number of cups of chips Charlie needs can be found out.
What is ratio?A ratio in mathematics shows how many times one number is contained in another. The ratio symbol is represented by a colon (:).A ratio is still valid if all of the quantities are multiplied by the same number. By dividing each quantity by the sum of all the numbers' common factors, ratios can be lowered (much like fractions are). The simplest version of a fraction is one in which the ratio's numbers are the smallest feasible integers.

Step-by-step explanation:
Given:
Length of a pyramid (lpy ) = 4 cm
Width of a pyramid (wpy ) = 3 cm
Height of a pyramid (hpy ) = 3 cm
It is given that the rectangular pyramid fits exactly on top of the prism, the length and width of the prism are the same for the base of the pyramid.
So, Length of a prism (lpr) =3 cm, width of a prism (wpr) = 3cm and height of a prism (hpr) = 3 cm
Volume of Prism (Vpr) = lpr × wpr × hpr
⇒ Vpr = 3 cm × 3 cm × 3 cm
⇒ Vpr = 27 cm³ ....(eq 1)
Volume of Rectangular Pyramid Vpy
= (lpy × wpy × hpy ) / 3
⇒ Vpy = (4 × 3 × 3) ÷ 3
⇒ Vpy = 12 cm³ ....(eq 2)
From 1 and 2, Volume of composite space,
Volume of composite space = Volume of prism + Volume of Pyramid
⇒ V = 27 cm³ + 12 cm³ = 39 cm³
⇒ V = 39cm³

How do you regular divide
Answer:
These are dividend, divisor, quotient and remainder.
Step-by-step explanation:
Determine the first digit or set of digits your divisor will go into at least once.
Determine the maximum number of times your divisor will go into the said digit or digits.
Place the answer over the corresponding digit. For multiple digits, place it over the last digit.
Multiply the answer from above by your dividend.
Place the result under your dividend starting from the left most digit.
Subtract the result from your dividend. Only subtract the digits that line up. For instance, if you have a five digit dividend, but the result is only two digits, only subtract using the first two digits of your dividend.
Bring down the next digit of your dividend beside the result.
Repeat the process using the new set of digits. Each time, bring down the next digit of your dividend.
Dendra's boat uses 3 gallons of gas in 4 hours. How many gallons of gas will she use in 15 hours?
Answer:11.25
Step-by-step explanation:because we have to find out how many gallons we have in one hour so you divide both sides by 4
4/4 is 1 hour
3/4 is 0.75 gallons then you have to multiply both sides by 15
1 hour times 15 is 15 hours
the 0.75 x 15 is 11.25
so the answer is 11.25 gallons that she uses in 15 hours

I cant find my answer help needed
Step-by-step explanation:
the domain is the interval or set of all valid x (input) values.
the range is the interval or set of all valid y (function result) values.
so, we see here, x goes from -2 to +2.
and y stays between -5 and -1.
the hole point at (-2, -1) means the point itself is not included. the full point (2, -1) means the point itself is included.
the domain is
-2 < x <= +2
"-2 < x" because (-2, -1) is not included.
"x <= +2" because (2, -1) is included.
the range is
-5 <= y <= -1
"y <= -1" because for the included point (2, -1) y can reach -1, even though (-2, -1) is excluded.

HUGE POINTS WOWZIE WOOZA
Answer:
(x-5)(x+4) = 0
Step-by-step explanation:
Pre-SolvingGivenWe are given the quadratic equation x²-x=20
And we want to factor it, meaning that we want to split it apart, usually to make it easier to solve.
SolvingFirst, let's subtract 20 from both sides, as when all 3 terms of a quadratic equation are on the same side, it makes it a lot easier to solve.
x² - x = 20
-20 -20
_______________
x² - x - 20 = 0
Now, we can get on to factoring.
In a quadratic equation, written as ax² + bx + c = 0 (like in here), b (the coefficient in front of just x, not x²) is equal to the sum of two numbers, while c is the product of the same two numbers.
The coefficient in front of x (b) is -1, and c is equal to -20.
Now think: which two numbers add up to -1, and multiply to equal -20?
Those numbers are -5 and 4.
Now, to factor a quadratic, we split it up into 2 binomials multiplied by each other, and each binomial is x + one of the numbers we found above. It looks like this: (x+1)(x+2). Remember that this only affects the left side; the right side stays the same.
In this case, we have -5 and 4, which will take the place of 1 and 2 in the example above.
Therefore, the factored form of x² - x - 20 = 0 is (x-5)(x+4) = 0.
