Given:
Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster.
To find:
The graph that represents the set of heights that satisfy this requirement.
Solution:
Let x be the height required for the ride.
Guests must be at least 54 inches tall to be able to ride the roller coaster. It means required height is greater than or equal to 54.
[tex]x\geq 54[/tex]
So, 54 and all values above 54 are in the solution set.
Since, 54 is included in the solution set, therefore there is a closed circle at 54. All values above 54 are in the solution set, so everything to the right of the circle is shaded.
Therefore, the correct option is C.
Answer:
c

Is the set of ordered pairs presented in the arrow diagram a function?Explain.
Answer:
no
Step-by-step explanation:
a function cant have the same range
Answer:
Functions as Arrow Diagrams When the domain and codomain of a function are finite sets then one can represent the function by an arrow diagram. Remember that an arrow diagram represents a function if exactly one arrow must leave each element of the domain and point to one element in the codomain.

The point (1, -5) is reflected across the y-axis. What are it's new coordinates?
Answer:
I'm in 6th grade and we talked about this so I can help!
Step-by-step explanation:
The answer is (-1,-5) which is in quadrant 3
Answer:
It would be (-1, -5) because it is reflected across the y axis which means the y axis stays the same, but the x axis changes

Are -4 ( x - 6) and -4 • x - 4 • 6 equivalent
Answer:
[tex]no[/tex]
Step-by-step explanation:
Lets solve the first half.
[tex]-4 ( x - 6) = -4x + 24[/tex]
Second one:
[tex]-4 times x - 4 times 6 = -4x -24[/tex]
Now compare.....Not the same right??
So your answer is: [tex]no[/tex]

Stacy spins the pointer 120 times and records it. The pointer lands 30 times on a section numbered 2, 19 times on 3, 25 times on 4, 29 times on 5, and 17 times on 6. A winning spin is a 2. FIND THE EXPERIMENTAL PROBABILITY OF LANDING ON 2
Answer:
1 / 4
Step-by-step explanation:
Number of trials = 120
Landing on 2 = 30
Landing on 3 = 19
Landing on 4 = 25
Landing on 5 = 29
Landing on 6 = 17
The experimental probability of landing in a two:
Experimental probability :
Number of times event occurs / Number of trials
Number of 2 landings = 30
Experimental probability of landing in a 2 ;
30 / 120 = 1/4

A new car is purchased for $32,500. The car depreciates every year ata
rate of 14%. Write an exponential function that represents that situation
Answer:
[tex]y=32500(0.86)^{x}[/tex]
Step-by-step explanation:
General exponentially depreciating function is given as
[tex]y= a(1-b)^{x}[/tex]------------(1)
Where a is initial value, b is percent depreciation/unit time and x is time
Here
[tex]a=32,500 \ \ \ b=0.14 \ \ \ and \ \ x \ is \ time \ in \ years[/tex]
Substituting above values in equation (1)
[tex]y=32500(0.86)^{x}[/tex]
At x=0
[tex]y=32500(0.86)^{0}\\y=32500[/tex]
At x=1
[tex]y=32500(0.86)^{1} \\y=27950[/tex]

Answer:
x = 18
m<A = 166°
Step-by-step explanation:
The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.
7x + 40 = 3x + 112
4x = 72
x = 18
m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166
7x+40 = 3x+112
x=18
7(18)+40
<A = 166
X + 3 =8
X- 5 =7
Please someone help?
Step-by-step explanation:
x+3=8
8-5=3 so x=5
7+5=12 / 12-7=5
12-5=7

What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
The line AE and CD
Now,
The angle sum property to find angle D:
Z + A + B + D = 360° Substitute the given values:
Z + 32 + 58 + D = 360 Simplify:
Z + D = 270 Subtract Z from both sides:
D = 270 - Z
Now, you need to find angle Z. To do that, you can use the fact that opposite angles in a quadrilateral are supplementary, meaning they add up to 180°2. So, angle Z and angle C are supplementary:
Z + C = 180°
You can use the fact that C is an exterior angle of triangle YZX and it is equal to the sum of the opposite interior angles3. Therefore, C = Y + X. Substitute this value:
Z + Y + X = 180°
You are given that Y = 10° and X = 6°. Substitute these values:
Z + 10 + 6 = 180 Simplify:
Z = 164
Now, you can use this value to find angle D:
D = 270 - Z Substitute Z = 164:
D = 270 - 164 Simplify:
D = 106
Therefore, by algebra the answer will be 106°.

Answer:
1: x = 47, y = 902: x = 92, y = 88, z = 923: 284: x = 90, y = 855: 133Explanation:
[1] - Ay = 90 (90 degree angle)
90 - 43 = 47, so x = 47
[2] - Cx = 92 because 180 - 88 = 92
x = 92 and y = 88 because 92 + 88 = 180
[3] - Cx = 28 because 90 - 62 = 28
[4] - Dx = 90 because 180 - 90 = 90
y = 85 because 42 + 53 = 95, 180 - 95 = 85
[5] - Ax = 133 because 180 - 47 = 133

The cafeteria can serve 32 lunches in 5 minutes. How long will it take them to serve 57 lunches?
Answer:
Around 364
Step-by-step explanation:
So to fund the answer, you need to find how much they can eat per minute: 32/5 = 6.4 (around 6 lunches)
Then you multiply this by 57: 57x6.4 = 364.8

Find value of X please
Answer:
x=7
Step-by-step explanation:
Step #1- Set the two lines equal to each other
10+12=x+15
Step #2- Solve for the line you have all values for
10+12=22
Step#3- Plug 22 back into the equation where the two lines are set equal to each other
22=x+15
Step #4- Solve for X algebraically
22=x+15
22-15=x
