To find the answer you divide the whole amount of 1456 by 7 since there is the 1 regular priced group and the remaining 6 discounted priced ticked. When you divide the 1456 by 7 it comes out to be 208 and to find the amount of the group of 6 you would multiply the 208 times the 6 and that will give you the amount of the dicount tickets sold. which is 1248.

Area of the horizontal rectangle.
A = L *W
L = 8cm
W = 3 cm
Area = 8 * 3 = 24 cm^2
Area of the Vertical Rectangle
The vertical rectangle has the same dimensions
L = 8 cm
W = 3 cm
Area = L * W
Area = 8 * 3
Area = 24 cm^2
Combined Area
Area = 24 + 24
Area = 48 cm^2 <<< Answer
Hey there!!
In order to solve for the area, let's divide this figure into two rectangles.
Area of a rectangle = Length × Breadth
First rectangle at the top - Length = 8 and width = 3
Hence, the area would be = 24cm²
The second triangle measures : Length = 3 and the width = 5
Area = 3 × 5
... 15cm²
Total area = 24cm² + 15cm²
... 24 + 15 cm²
... 39cm²
Hope my answer helps!!
A homeowner has an octagonal gazebo inside a circular area. Each vertex of the gazebo lies on the circumference of the circular area. The area that is inside the circle, but outside the gazebo, requires mulch. This area is represented by the function m(x), where x is the length of the radius of the circle in feet. The homeowner estimates that he will pay $1.50 per square foot of mulch. This cost is represented by the function g(m), where m is the area requiring mulch. Which expression represents the cost of the mulch based on the radius of the circle?
If we draw the diagonals of the octagonal gazebo, the 4 diagonals divide the octagon into 8 triangles.
Note that each triangle is an isosceles triangle whose equal sides are x, the radius of the circle.
The top angle of each triangle is obtained by dividing the full angle by 8.
So, each top angle = [tex]\frac{360}{8}[/tex]
= 45°
Now, in fig., consider one of the triangles Δ OAB. Draw an altitude OC from O to the opposite side AB.
This altitude OC bisects the top angle 45°.
Therefore, ∠ AOC = 22.5°.
Now, in Δ AOC,
[tex]sin 22.5=\frac{AC}{OA}[/tex]
[tex]=\frac{AC}{x}[/tex]
So, AC = x sin 22.5°
Note that, AB = 2 AC.
Therefore, AB = 2x sin 22.5°.
Also, [tex]cos 22.5=\frac{OC}{OA}[/tex]
[tex]=\frac{OC}{x}[/tex]
So, OC = x cos 22.5°.
Area of Δ AOB = [tex]\frac{1}{2}(AB)(OC)[/tex]
= [tex]\frac{1}{2}[/tex] × (2x sin 22.5°) × (x cos 22.5°)
= [tex]\frac{1}{2} x^{2}[/tex] (2 sin 22.5° cos 22.5°)
= [tex]\frac{1}{2} x^{2}[/tex] sin 45°
= [tex]x^{2}[/tex] / [tex]2\sqrt{2}[/tex]
Area of the octagonal gazebo = 8 × one triangular area
= 8 × ([tex]x^{2}[/tex] / [tex]2\sqrt{2}[/tex])
[tex]=2\sqrt{2} x^{2}[/tex]
[tex]=2.828x^{2}[/tex]
Area required for mulch = circular area - area of the gazebo
[tex]=3.14x^{2} -2.828x^{2}[/tex]
[tex]=0.312x^{2}[/tex]
Now, cost per unit area = $1.50.
Hence, total cost g(m) = area × cost per unit area
Total cost g(m) = [tex]0.312x^{2}[/tex] × 1.5
[tex]=0.468x^{2}[/tex]
Hence, total cost g(m) = [tex]0.468x^{2}[/tex].

Which graph passes the vertical line test?
There are no graphs shown, but the vertical line test is something you can use to find out if a function works. If you make a vertical line anywhere on one of the graphs, it should only pass through one point. For example, a regular straight line almost always passes the vertical line test. If it's a sideways parabola, it will not.

Which pair of complex numbers has a real-number product? (1 + 2i)(8i) (1 + 2i)(2 – 5i) (1 + 2i)(1 – 2i) (1 + 2i)(4i)
Answer:
(1+2i)(1-2i)
Step-by-step explanation:
Answer:
(1+2i)(1-2i)
Step-by-step explanation:
Following are the pairs of the complex number:
(1+2i)(8i),
(1 + 2i)(2 – 5i)
(1+2i)(1-2i) and (1+2i)(4i)
We have to check which pair out of these is a real number product, which means which pair do not contain terms consisting of "i".
A. [tex](1+2i)(8i)= 8i+16i^{2}[/tex]
=[tex]8i-16[/tex]
B. [tex](1+2i)(2-5i)=2-i-10i^{2}[/tex]
=[tex]12-i[/tex]
C. [tex](1+2i)(1-2i)=1^{2}-4i^{2}[/tex]
=[tex]5[/tex]
D. [tex](1+2i)(4i)=4i+8i^{2}[/tex]
=[tex]4i-8[/tex]
Since, A,B,D contains the term "i" which means they are not real valued, therefore option C that is (1+2i)(1-2i) has a real number product.

There is 1 solution, which is 3/4.
To show this, you actually have to solve the equation. First, you distribute -1 into(9 - 3h) and distribute -3 into (h + 2). In doing so, you should be left with "6h - 9 + 3h = 6 - 3h - 6". Next you combine like terms on each side, so you add 3h to 6h and you subtract 6 from 6. Now you should have "9h - 9 = -3h". Then, you start to solve by subtracting 9h from both sides. You should have -9 = -12h, which you divide -12 on both sides to get h by itself. Finally, you have h = 9/12 (since the negatives on the top and bottom cancel out) which simplified (divided by 3/3) is 3/4. Thus meaning there is only 1 answer.

The table shows the five most populated countries in the world. How many times as many people live in China then in the United States? Round to the nearest 10th if necessary.
The answer is about 4 times as many people live in China then in the United States
There are 4.4 times more people living in china than united states as the definition of ratio says "the quantitative relation between two amounts showing the number of times one value contains or is contained within the other".
What is ratio?The indicated quotient of two mathematical expressions is referred to as a ratio. A/B stands for an ordered pair of numbers where B does not equal 0. A proportion is an equation that sets two ratios at the same value. For instance, you could write the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls.
Here,
To find that how many times as many people live in China then in the United States, we need to divide the population of china by the population of united states.
let x be the value of how many times as many people live in China then in the United States,
so, the population of china=1.325 billions
the population of united states=0.304 billions
x=1.325/0.304
x=4.356
x≈4.4 times
As stated in the definition of ratio, "the quantitative relation between two amounts showing the number of times one value contains or is contained within the other," there are 4.4 times as many people living in China as there are in the United States.

the number of units in the perimeter of a square is less than or equal to the number of square units in the area of the square which side length of a square provides a counterexample?
Answer:
2
Step-by-step explanation:2+2
The side lengths of a square in which the perimeter of a square is greater than its area is 1 unit, 2 units, and 3 units.
What is a square?A square is a 2D figure of which all sides are equal.
We know that the perimeter of a square is the sum of the lengths of all the sides and the area of a square is (side)².
Assuming a square has a side length of 4 units.
Therefore the perimeter of the square is 4×side = 4×4 = 16 units.
Now the area of the square will be (4)² = 16 sq units.
Now assuming the side length of the square is 2 units.
The area of the square is (2)² = 4 units and the perimeter is (2×4) = 8 units.
∴ The side length which provides a counter-example is 2 units.
Basically, we have to determine the numbers that when multiplied by 4 are greater than it's square such numbers are 1, 2, 3.

ANSWER
ANSWER TO QUESTION 1.
If you give [tex]x[/tex] surfing lessons, then you will earn $ [tex]25x[/tex]
If you are charged $200 for using the place, then your profit will reduce by $200.
The profit function is given by
[tex]P(x)=25x-200[/tex] dollars.
The y-intercept is [tex]-200[/tex]. It is negative because it is a cost which is a liability. So it does not add to your profit.
ANSWER TO QUESTION 2.
The slope is [tex]25[/tex]. It is positive because as the number of hours increases, the profit earned also increases. In other words there is a direct relation between the number of hours worked and the profit earned.
ANSWER TO QUESTION 3.
The slope intercept form is when an equation is written in the form;
[tex]y=mx+c[/tex],
where [tex]m[/tex] is the slope and [tex]c[/tex] is the y-intercept. The profit function in slope intercept form is
[tex]P(x)=25x-200[/tex]
ANSWER TO QUESTION 4.
If you break even, then the difference between the revenue and cost is zero. So we equate the profit function to zero.
[tex]25x-200=0[/tex]
[tex]25x=200[/tex]
[tex]x=8[/tex]
Therefore you need to give 8 different lessons to break even.
ANSWER TO QUESTION 5.
If you give 20 lessons, the [tex]x=20[/tex]. We need to substitute
[tex]x=20[/tex] in to the profit function to calculate the profit made after 20 lessons.
[tex]P(20)=25(20)-200[/tex]
[tex]P(20)=500-200[/tex]
[tex]P(20)=300[/tex].
ANSWER TO QUESTION 6.
If the new price is $75, then the new profit function becomes
[tex]P(x)=75x-200[/tex]
ANSWER TO QUESTION 7.
To find the number of lessons that lets you break even, we equate the new profit function to zero.
[tex]75x-200=0[/tex]
We solve for x by adding 200 to both sides of the equation.
[tex]\Rightarrow 75x=200[/tex]
We now divide through by 75
[tex]\Rightarrow x=\frac{200}{75}[/tex]
[tex]\Rightarrow x=2\frac{2}{3}[/tex]
Therefore you would have to 2\frac{2}{3} lessons to break even. That is approximately 3 lessons.
ANSWER TO QUESTION 8.
If you give 20 lessons and we want to find the profit you made with this new profit function, then we have to plug in [tex]x=20[/tex] in to [tex]P(x)=75x-200[/tex].
That is,
[tex]P(20)=75(20)-200[/tex]
[tex]P(20)=1500-200[/tex]
[tex]P(20)=1300[/tex] dollars

3 + x/2 = 10 ..............This is given
Step 2)
x/2 = 7 ....................... Multiplication property of equality.
This step is wrong. This step is called "Subtraction property of equality". This means you have to subtract 3 from both sides
3 + x/2 - 3 = 10 - 3

x/ 2 = 7
Step 3)
x = 14 ....This is called "Multiplication property of equality" because you multiply both sides by 2.

Judy planted vegetables on a piece of land. The land is in the right-angled triangular shape. Given the longest side of the land is y metre. The other two sides of the land are 2x metre and (2x+6) metre respectively. He fenced the land with 72 metres of barbed wire. Find the length, in metre , of each side of the land.
We know that the perimeter is 72 meters, so we have
[tex] y+2x+(2x+6)=72 \iff y+4x+6=72 \iff y=-4x+66 [/tex]
Now we can use the pythagorean theorem: the sum of the squares of the legs is the square of the hypotenuse:
[tex] (2x)^2+(2x+6)^2 = y^2 \iff (2x)^2+(2x+6)^2 = (-4x+66)^2 [/tex]
Expand the squares to get
[tex] 8 x^2 + 24 x + 36 = 16 x^2 - 528 x + 4356 [/tex]
Bring everything to the right hand side to get
[tex] 8 x^2 - 552 x + 4320 = 0 [/tex]
Divide both sides by 8:
[tex] x^2 - 69x + 540 = 0 [/tex]
This equation has solutions [tex] x=9,\ x=60 [/tex]
This solutions would yield the following side lengths:
[tex] x=9\implies\begin{cases} 2x = 18\\2x+6=24\\-4x+66=30\end{cases}[/tex]
[tex] x=60\implies\begin{cases} 2x = 120\\2x+6=126\\-4x+66=-174\end{cases}[/tex]
Since we can't have negative side lengths, we can only accept the solution x=9.
In fact, you can check that 18,24,30 is a pythagorean triplet, i.e.
