Jin sells concert tickets at the theater box office. The ratio of student tickets to adult tickets sold is 4 : 5. Each student ticket costs $5, and each adult ticket costs $7. Jin sells 189 tickets altogether. Part A: How many student tickets does Jin sell? How many adult tickets? Explain your reasoning. Part B: How much more money does Jin receive from selling adult tickets than from selling student tickets? Explain your reasoning
Step-by-step explanation:
1) if total number of the saled tickets is 189, then it is possible to write s+a=189, where s - number of student tickets, a - adult tickets.
2) if the ratio is 4:5, then it is possible to write s:a=4:5;
3) using the two equations it is possible to make up the system:
[tex]\left \{ {{s+a=189} \atop {\frac{s}{a} =\frac{4}{5} }} \right.[/tex]
4) Part A: after solution the system above the number of student tickets = 84; adult tickets = 105.
5) Part B: the revenue from selling the adult tickets is: 105*7=735, the student tickets is: 84*5=420. Then the required difference is: 735-420=$ 315.

Find the measure of ∠YOZ. Which angle relationship did you use?
Answer:
Step-by-step explanation:
The measure of angle ∠WOV is 60 degrees and The measure of angle ∠YOZ is also 60 degrees.
What is an angle?
Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
∠WOX = 30
It can be seen that the ∠XOY and ∠VOX are equal and 90 degrees.
The measure of angle ∠WOV will be
∠WOV + ∠WOX = 90
∠WOV + 30 = 90
∠WOV = 60
The measure of angle ∠YOZ will be
∠WOX + ∠XOY + ∠YOZ = 180 (Supplementary angle)
30 + 90 + ∠YOZ = 180
∠YOZ = 60

Say that Romania puts a tariff of 6% on its exports and 21% on its imports. If Romania has a trade deficit of (equivalent US dollars) $26. 76 billion and gained tariff revenue of $18. 9603 billion, how much are Romania’s imports worth? a. $62. 56 billion b. $64. 29 billion c. $76. 17 billion d. $97. 04 billion.
Answer:
c. $76.17 billion
Step-by-step explanation:
The relations between imports, exports, and tariffs can be described by ...
0.06E +0.21I = $18.9603 . . . . . . total tariff revenue
I -E = 26.76 . . . . . . . . . . . . . . . . trade deficit
Solving the second equation for E gives ...
E = I -26.76
Substituting into the first equation yields ...
0.06(I -26.76) +0.21I = 18.9603
0.27I = 18.9603 +1.6056 = 20.5659 . . . . add 1.6056 to both sides
I = 10.5659/0.27 = 76.17
Romania's imports are worth about $76.17 billion.

Additional comment
The exports are worth about $76.17 -26.76 = $49.41 billion.

It takes 1/8 of a roll of wrapping paper to completely cover all 6 sides of a small box that is shaped like a rectangular prism. The box has a volume of 10 cubic inches. Suppose the dimensions of the box are tripled. How many rolls of wrapping paper will it take to cover all 6 sides of the new box? What is the volume of the new box?
a. The number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls
b. The volume of the new rectangular box is 270 in³
Area of rectangular prism
Since the small box is a rectangular prism, its surface area, A = 2(lb + lh + bh) where
l = length, b = width and h = height.Now, when the dimensions are tripled, its new area is A' = 2(LB + LH + BH) where
L = 3l, B = 3b and H = 3h.So, A' = 2(LB + LH + BH)
= 2((3l)(3b) + (3l)(3h) + (3b)(3h))
= 2(3)(3)(lb + lh + bh)
= 18A
a. Number of rolls of wrapping paperThe number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls
Now, since we require 1/8 of a roll of wrapping paper to initially cover all 6 sides of the small box with dimensions, l,b and h. Then the number of rolls we require to cover the box when its dimensions are tripled are (since the area is proportional to the number of rolls)
N = 18 × 1/8
= 18/8
= 9/4
= 2¹/₄ rolls
The number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls
b. Volume of the new rectangular box
The volume of the new rectangular box is 270 in³
The volume of the rectangular box V = lbh where
l = length, b = width and h = heightWhen the dimensions are tripled, V' = LBH where
L = 3l, B = 3b and H = 3h.So, V' = LBH
= (3l)(3b)(3h)
= 27lbh
= 27V
Now since the initial volume of the rectangular box, V = 10 in³
V' = 27V
V' = 27 × 10 in³
V' = 270 in³
So, the volume of the new rectangular box is 270 in³

A company manufactures a rubber ball shaped like a sphere. The rubber ball has a radius of 4.5 centimeters.
Which measurement is closest to the volume of this rubber ball in cubic centimeters?
Answer:
The radius of a rubber ball, r = 4.5 cm
We need to find the volume of this rubber ball.
The formula for the volume of a sphere is given by :
V=\dfrac{4}{3}\pi r^3V=34πr3
Put r = 4.5 cm in the above formula
\begin{gathered}V=\dfrac{4}{3}\pi \times (4.5)^3\\\\V=381.70\ cm^3\\\\\text{or}\\\\V=382\ cm^3\end{gathered}V=34π×(4.5)3V=381.70 cm3orV=382 cm3

A line is drawn on a coordinate grid by the equation y = 1. Which of the following lines would represent a row perpendicular to it?
A. a line containing the point (5,2)
B. y = 1
C. x = 4
D. y = 3
Answer:
C
Step-by-step explanation:
In the Cartesian coordinate system, a line perpendicular to the line that's across the Y axis is a row across the X axis. You see Y=1 is the line across Y axis, so we need a row that's across the X axis. So C. X=4 is the ideal choice.
If a line is drawn on a coordinate grid by the equation y = 1 then x=4 would represent a row perpendicular to it.
What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
A line is drawn on a coordinate grid by the equation y = 1.
The equation y = 1 represents a horizontal line on the coordinate grid, passing through all the points where y-coordinate is 1.
A line that is perpendicular to a horizontal line is a vertical line.
The vertical line x = 4 passes through all the points where x-coordinate is 4, and is perpendicular to the horizontal line y = 1.
Hence, if a line is drawn on a coordinate grid by the equation y = 1 then x=4 would represent a row perpendicular to it.

Answer:
3 copies
Step-by-step explanation:

2/5 * 30 is 12
12+30= 42
45-42=3
I believe this is correct
Answer:
3
Step-by-step explanation:
If 2/3 of 45 were sold then what is left is 1 - 2/3 = 1/3 of 45 or (1/3)*45 = 15 copies.
Then 4/5 of 15 were sold and what is left is 1 - 4/5 = 1/5 of 15 or 3 copies.
