Answer:
33 adult tickets and 21 student tickets
Step-by-step explanation:
We will create a system of equations.
Let x = the number of adult tickets sold and let y = the number of student tickets sold
x + y = 54
3x + 2y = 141
We can cancel out the y by multiplying the first equation by -2.
-2x - 2y = -108
3x + 2y = 141
Adding these equations together we get:
x = 33
Plugging this into the equation, we have:
38 + y = 54
y = 21
There were 33 adult tickets and 21 student tickets

Meyer rolls two fair, ordinary dice with the numbers $1,2,3,4,5,6$ on their sides. What is the probability that at least one of the dice shows a square number?
Two numbers on each die are squares: 1 and 4. 4 numbers on each die are not squares: 2 , 3, 5, and 6. there are 16 ways for him to roll a non-square die, out of 36 outcomes for the pair of dice. The other 20 options each have a square number showing on one or both dice. So, the probability is 5/9. hope this helps please pick my answer as brainliest, have a good day!
Write an equation of the line with the given slope and y-intercept.
Answer:
A. [tex] y = \frac{1}{4}x + 2 [/tex].
Step-by-step explanation:
Equation of a line in slope-intercept form, is given as [tex] y = mx + b [/tex].
Given a slope (m) of ¼, and y-intercept (b) of 2, we can get the equation if the line by substituting m = ¼, and b = 2 into [tex] y = mx + b [/tex].
Thus, the equation of the line would be:
[tex] y = \frac{1}{4}x + 2 [/tex].

The entry fee to a fun park is $20. Jackson spent a total of 35 at the park. If z represents the number of rides jackson went on, which equation represents the situation and what is the value of z that makes the equation true?
A= 2.50=35
x=14
B= 2.50z=20
x=8
C= 20z+2.50=35
c=2
D= 20+2.50z=35
x=6
Answer: The answer is d.
Step-by-step explanation:
If the entry amount is $20 then you want to subtract $20 from $35 and that leaves you with $15 now if you divide $15 in $2.50's you get 6

−4(m+3)=24
What does m=
Answer: m= -9
Step-by-step explanation: First use distributive property, -4(m) is -4m and -4(3) is -12. Then you have -4m -12 =24. Then use 12 and add it to the other side of the equation, cause of the subtraction sign, 12+24=36. Then you have -4m=36. Then divide the 4 to get the m by its self. 36 divided by -4 is -9. Your answer is m=-9
Hope this helps :)

. A right cylindrical drum is to hold 7.35 cubic feet of liquid. Find the dimensions (radius of the base and height) of the drum which would minimize the surface area. What is the minimum surface area
Answer:
[tex]r=1.05\ \text{ft}[/tex]
[tex]h=2.12\ \text{ft}[/tex]
[tex]20.91\ \text{ft}^3[/tex]
Step-by-step explanation:
r = Radius
h = Height
Volume of cylinder = [tex]7.35\ \text{ft}^3[/tex]
[tex]V=\pi r^2h\\\Rightarrow h=\dfrac{V}{\pi r^2}\\\Rightarrow h=\dfrac{7.35}{\pi r^2}[/tex]
Surface area is given by
[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi r^2+2\pi r\dfrac{7.35}{\pi r^2}\\\Rightarrow A=2\pi r^2+\dfrac{14.7}{r}[/tex]
Differentiating with respect to radius we get
[tex]\dfrac{dA}{dr}=4\pi r-\dfrac{14.7}{r^2}[/tex]
Equating with zero we get
[tex]0=4\pi r-\dfrac{14.7}{r^2}\\\Rightarrow 4\pi r=\dfrac{14.7}{r^2}\\\Rightarrow r^3=\dfrac{14.7}{4\pi}\\\Rightarrow r=(\dfrac{14.7}{4\pi})^{\dfrac{1}{3}}\\\Rightarrow r=1.05[/tex]
[tex]\dfrac{d^2A}{dr^2}=4\pi-2\times \dfrac{14.7}{r^3}\\\Rightarrow \dfrac{d^2A}{dr^2}=4\pi+2\times \dfrac{14.7}{1.05^3}\\\Rightarrow \dfrac{d^2A}{dr^2}=37.96>0[/tex]
So, the value of the function is minimum at [tex]r=1.05[/tex]
[tex]h=\dfrac{7.35}{\pi r^2}=\dfrac{7.35}{\pi 1.05^2}\\\Rightarrow h=2.12[/tex]
So, the radius and height which would minimize the surface area is 1.05 feet and 2.12 feet respectively.
Surface area
[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi \times 1.05^2+2\pi 1.05\times 2.12\\\Rightarrow A=20.91\ \text{ft}^3[/tex]
The minimum surface area is [tex]20.91\ \text{ft}^3[/tex].

Which of the following represents the highest degree of relative performance?
Answer:
idek
Step-by-step explanation:
the ratio of two numbers is 7:3 and their sum is 50,find the two numbers
Please show explanation
Answer:
35 and 15
Step-by-step explanation:
7+3=10
50÷10=5 so you multiply each number by five
7×5=35
and
3×5=15
Step-by-step explanation:
let the number be 7x &3x
now,
7x+3x= 50
10x=50
x=50
10
x=5
again,
7x=7×5 = 35
3x= 3×5 =15
therefore the two number are 35 & 15.
hope it helps.

find the median of this set of numbers 5,11,2,12,4,2
Step-by-step explanation:
2,2,4,5,11,12
the median is 5
Answer:
2, 2, 4, 5, 11, 12 (put the numbers from least to greatest)
since it's an even set of numbers, the median is between two of the numbers. so find where the middle is by counting how many numbers you have, and then dividing by 2. in this case it's 3, so there should be 3 values on either side of the median. so the median is between 4 and 5. So you add those two values together and divide by 2 (because that's how many numbers you added) and you get 4.5 as your median.
Step-by-step explanation:
