Answer:
Upper deck = $38
Goal View = $63
Sidelines = $88
Step-by-step explanation:
Represent
- Sidelines with S
- Goal-view with G
- Upper-deck with U
We have that:
[tex]S = 25 + G[/tex]
[tex]S = 50 + U[/tex]
[tex]G = 2U - 13[/tex]
Required
Solve for S, G and U
Substitute 25 + G for S in the second equation
[tex]25 + G = 50 + U[/tex]
Make G the subject
[tex]G = 50 -25+ U[/tex]
[tex]G = 25+ U[/tex]
Substitute 25 + U for G in the third equation
[tex]25 + U = 2U - 13[/tex]
Collect Like Terms
[tex]U - 2U = -13 - 25[/tex]
[tex]-U = -38[/tex]
[tex]U = 38[/tex]
Substitute 38 for U in [tex]G = 25+ U[/tex]
[tex]G = 25 + 38[/tex]
[tex]G =63[/tex]
Substitute 63 for G in [tex]S = 25 + G[/tex]
[tex]S = 25 + 63[/tex]
[tex]S = 88[/tex]

Question 1 (1 point)
A mail carrier divides 4,830 envelopes into boxes. Each box can hold a maximum of 50 envelopes.
What is the minimum number of boxes the mail carrier must use?
Answer:
97 boxes
Explanation:
4,830÷50= 96.6
You then have to round 96.6 up and you get 97.
To check your answer:
97×50= 4,850
Even though having 97 boxes leaves more room for envelopes, having 96 boxes will leave all the boxes full with remaining envelopes. 96 boxes isn't enough for 4,830 envelopes.

The area of the rectangular sheet is 500cm square. If the length of the sheet is 25cm, what is its width? Also find the perimeter of the rectangular sheet.
Answer:
20cm Perimeter: 90
Step-by-step explanation:
Hope this helps!(^-^)
Step-by-step explanation:
area of rectangular sheet is 500 CM square
length =25cm
area =l×b
500cm2=25cm×b
500cm2÷25cm=b
20cm=b
b=20cm
again,
perimeter =2(l+b)
perimeter =2(25cm+20)
perimeter =2×45
perimeter =90cm

Answer:
20Step-by-step explanation:
The equation of shifted function y = ax² is y = a(x-h)²+k, where h tells us how many units we move left (h<0) or right (h>0) and k tells how many units up (k>0) or down (k<0)
y = x² - 20 = 1(x - 0)² + (-20) ⇒ k = -20<0
So it's shifted 20 units down.

Is the relation shown in the table below a function? Explain.
Answer
No
Step-by-step explanation:
it is not a function because 9 and three are a pair but so are 27 and 3. that makes it not a function
No, the given relation is not a function. A function is a connection between inputs in which each input is connected to precisely one output.
What is a function?A function is a relationship between a number of inputs and outputs. A function is an association of inputs where each input is coupled with exactly one output. There is a range, co-domain, and domain for every function.
Given, a table where points are denoted as inputs and outputs.
To prove the relation is a function:
A relation between a collection of inputs and outputs is known as a function.
A function is a connection between inputs in which each input is connected to precisely one output.
But here, input value of 3 have two outputs.
Which gives us contradiction.
Therefore, a given relation is not a function.

Question 1
You notice a hot air balloon descending. The elevation h (in feet) of the balloon is modeled by the function h(x)=-11x+330, where x is the time (in seconds) since you first noticed the hot air balloon.
Graph the function and specify its domain and range. Then interpret the slope and intercepts of the graph.
Answer:
Domain
[tex]x\in [0\,s,30\,s][/tex]
Range
[tex]h \in [0\,ft,330\,ft][/tex]
The h-Intercept represents the initial height of the balloon. The balloon has an initial height of 330 feet.
The x-Intercept represents the time when the balloon reaches the ground. The balloon takes 30 seconds to descend and reach the ground.
The slope represents the ratio of the change in the elevation of the balloon to the change in time. A slope of -11 means that balloon descends 11 feet per second.
Step-by-step explanation:
Both the time (domain), measured in seconds, and the height (range), measured in feet, are positive variables. The hot air balloon start at a height above and descends to the ground. Which means that domain and range of the function are, respectively:
Now we find the upper bound of the height of the hot air balloon. If we know that [tex]t = 0\,s[/tex], then the upper bound is:
[tex]h(0) = -11\cdot (0)+330[/tex]
[tex]h(0) = 330\,ft[/tex]
Range
[tex]h \in [0\,ft,330\,ft][/tex]
Now we find the upper bound of time. If we know that [tex]h = 0\,ft[/tex]. then the upper bound is:
[tex]-11\cdot x +330 = 0[/tex]
[tex]11\cdot x = 330[/tex]
[tex]x = 30\,s[/tex]
Domain
[tex]x\in [0\,s,30\,s][/tex]
The h-Intercept represents the initial height of the balloon. The balloon has an initial height of 330 feet.
The x-Intercept represents the time when the balloon reaches the ground. The balloon takes 30 seconds to descend and reach the ground.
The slope represents the ratio of the change in the elevation of the balloon to the change in time. A slope of -11 means that balloon descends 11 feet per second.

Find the 15th term or the geometric sequence 7, -21, 63,
33480783
Step-by-step explanation:Finding the Common Ratio:
We know that the formula for the common ratio of a GP is:
r = aₙ / (aₙ₋₁) (Where n is any integer)
replacing the values, taking n=2
r = -21 / 7
r = -3
Solving for the 15th Term:
We know that the Formula for the nth term of a GP:
G(n) = a * r ⁿ⁻¹ (where a is the first term and r is the common ratio)
replacing the values (taking n = 15 since we need the 15th term)
G(15) = 7 * (-3)¹⁴
G(15) = 33480783
Hence, the 15th term of the given GP is 33480783
