Answer:
The cost of one student ticket = $6
Step-by-step explanation:
They were charged for three student tickets and two adult tickets.
Let the cost of one student ticket = a
Let the cost of one Adult ticket = b
If a student ticket costs 3/4 as much as an adult ticket costs
a = 3/4(b)
= 3b/4
For his family of 5 to play it costs $34.
Hence:
3a + 2b = $34
a = 3b/4
3(3b/4) + 2b= 34
9b/4+ 2b = 34
9b + 8b / 4 = 34
17b/4 = 34
17b = 34 × 4
b = 136/17
b = $8
The cost of one Adult ticket = $8
Note that:
a = 3b/4
a = 3(8)/4
a = 24/4
a = $6
Therefore, the cost of one student ticket = $6

The buyer for a chain of stores purchased leather couches in bulk, paying $750 each. The stores will sell each leather couch for $1,275. What is the mark-up percentage?
Answer:
The mark-up percentage is 70%
Step-by-step explanation:
Let us revise the rule of the mark-up percentage
[tex]M=\frac{S-P}{P}[/tex] × 100%, where
M is the mark-up percentageS is the selling priceP is the purchasing pricelet us use this rule to solve the question
∵ The buyer purchased leather couches in bulk, paying $750 each
∴ P = 750
∵ The stores will sell each leather couch for $1,275
∴ S = 1,275
→ Substitute them in the rule above
∴ [tex]M=\frac{1275-750}{750}[/tex] × 100%
∴ [tex]M=\frac{525}{750}[/tex] × 100%
∴ M = 70%
∴ The mark-up percentage is 70%

Adam is saving money to buy a new computer that costs $550. His mom has given him $100 to begin. Each week, he deposits money into his savings account. The table shows the balance after t weeks. Time (t) in weeks 0 1 2 3 4 Balance (b) $100 $125 $150 $175 $200 Write an equation to represent this situation.
Answer:
25t + 100 = 550
Step-by-step explanation:
Notice that for every week, the balance increases by $25. That means t will be multiplied by 25 like this: 25t
There is already $100 on top of that, so add 100 to it like this: 25t + 100
Since Adam is saving for a $550 computer, this sum has to equal 550
25t + 100 = 550
If you want to find out how many weeks it will take to get that computer, subtract 100 from both sides
25t + 100 = 550
- 100 - 100
25t = 450
Divide both sides by 25
25t/25 = 450/25
t = 18
It will take Adam 18 weeks to save up and buy that computer.

8 + 6.9x what is the value of x
8 + 6.9x = 0
(Setting equation to 0 to figure out what x could be)
6.9x = -8
(Subtract 8 to both sides to isolate the x)
X = -8/6.9 or -1.15942
(Divide 6.9 to isolate x and you get your answer)
Juana invests $1,500 in an account accumulating 3% interest according to the equation v=1500(1.03)^y, where v
represents the value of the account after y years. Marquez and Calvin invest the same amount of money at the same
rate. Marquez invests three years before Juana, and Calvin invests two years after Juana. By what factor would
Calvin's investment need to be increased to equal Marquez's investment at any time after Calvin's investment is
made?
A. 86.3%
B. 97.1%
C. 115.0%
D. 115.9%
Calvin's investment need to be increased by a factor of 115.9% to equal Marquez's investment at any time after Calvin's investment is made.
What is an exponential function?An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
Let v represent the value of the account after y years. Hence:
For Juana:
[tex]v=1500(1.03)^y[/tex]
Marquez invests three years before Juana, Hence:
[tex]v'=1500(1.03)^{y+3}=1500(1.03)^y(1.03)^3=(1.03)^3*v=1.092727v[/tex]
Calvin invests two years after Juana. Hence:
[tex]v"=1500(1.03)^{y-2}=1500(1.03)^y*(1.03)^{-2}=(1.03)^{-2}v[/tex]
v' / v" = ((1.03)³ * v) / ((1.02⁻²) * v) = 1.159 = 115.9%
Calvin's investment need to be increased by a factor of 115.9% to equal Marquez's investment at any time after Calvin's investment is made.

Step-by-step
Step-by-step explanation:
the rules of the angles of 2 lines intersecting each other.
that means the angles on one side of the first line sind the intersection point, are the same as on the other side of the line - just left-right interchanged.
and to have a third line, parallel to the first line, where the exact same angles have to be, where the second line intersects the third line (a parallel line is like a mirror image of the first line : every look and feel has to be the same).
and then remember : all angles around a single point in one side of a line must be together 180°.
so, if the support beam has an angle of 125° with the top "line", the second angle there (the exterior Angie at that point) is then 180 - 125 = 55°.
this is all at the bottom side of the top "line".
these angles are therefore left-right exchanged the same on the top side of the top "line". so, 55° and 125° instead of 125° and 55°.
these angles at the top of the top "line" must be now exactly the same at the top of the parallel bottom "line" of the truss.
so, the interior angle there is 55°. and the exterior angle is 125°.

How do the absolute values of -12.5 and 11.5 compare?
Answer:
(−12.5) (11.5) = −143.75 Or -12.5 < 11.5
Step-by-step explanation:
hope this helps
Answer:
|-12.5|>|11.5|
Step-by-step explanation:
When you take the absolute value of a number you're essentially measuring the scalar value or magnitude of that number. "How big is that number as a number not as in + or -".
In other words the number becomes positive
|-12.5|=12.5
|11.5|=11.5
since 12.5>11.5
we can then say
|-12.5|>|11.5|
plz help! how many zeros abs relative minimums does it have?
Answer:
The degree of f(x) is even, and the leading coefficient is negative. There are 3 real zeros, and 1 relative minimum values.
Step-by-step explanation:
We have the graph of f(x).
First, since both end behaviors are the same, our function must be an even-degree.
Second, since both end behaviors are going towards negative infinity, this means that the leading coefficient of our function must be negative.
The real zeros are whenever the graph touches or crosses the x-axis. We can see that this happens three times. I've circled them in blue in the image below.
Finally, relative minimum values are the lowest points in a graph, and then happen between a decreasing and then an increasing curve.
From, the graph, we only have one relative minimum value. This is circled in black in the image below.
Note that the arrows whether the curve is decreasing or increasing. We can see that the curve to the left of the minimum is decreasing, while the curve to the right of the minimum is increasing.
So, our solution is:
The degree of f(x) is even, and the leading coefficient is negative. There are 3 real zeros, and 1 relative minimum values.
And we're done!

7 pencils cost £5.95.
How much do 11 pencils cost?
Answer:
11 pencils cost £9.35.
Step-by-step explanation:
Given;
7 pencils = £5.95
1 pencil = 5.95 ÷ 7
= £0.85
Now,
11 pencils = 11 × 0.85
= £9.35
Answer:
9.35$
Step-by-step explanation:
to find the cost of 11 pencils first we need to find the price of 1.
5.95 divided by 7 = 0.85$ (the price of one pencil)
we need to find the price of 11 pencils though.
0.85x11= 9.35$
