a ticket originally cost $20, but it's price decreases by 20%
ANSWER ASAP MARKING BRAINLIEST HELPPP
Answer:
$16
Step-by-step explanation:
20% is the same as 0.2 in decimal form, since its decreasing you multiply $20 by 0.8 to get 16. If it was increasing, it would be 20 times 1.2
Answer:
$16.00
Step-by-step explanation:
This is the answer because:
1) Since the price decreases by 20%, we have to first figure out what 20% of $20 is:
20% of $20 = 4
2) Next, we just have to subtract 4 from 20 so we can find out how much the cost is:
$20.00 - 4 = $16.00
Therefore, the answer is $16.00.
Hope this helps! :D

A tela de um celular é um retângulo de 5,2 cm de largura por 8,6 cm de comprimento. Calcule a área da tela desse celular, em m². Dica: 1m² = 10000 cm²
Responda:
0,004816 m²
Explicação passo a passo:
Dado que :
Dimensão da tela retangular do celular = 5,6 cm por 8,6 cm
A área de um retângulo = comprimento * largura
Área da tela do celular = 5,6 cm * 8,6 cm = 48,16 cm²
A área em m²:
1m² = 10000cm²
Conseqüentemente,
(48,16 / 10.000) m²
= 0,004816 m²
Does this sequence converge or diverge? \left\{\frac{10n-6}{2n-3}\right\} { 2n−3 10n−6 }
Answer:
The sequence converges
Step-by-step explanation:
Given the sequence Un = 10n-6/2n-3
To determine whether the sequence converges or diverges, we will have to take the limit of the sequence as n goes large.
[tex]\lim_{n \to \infty} \left\{\frac{10n-6}{2n-3}\right}\\[/tex]
Divide through by n
[tex]= \lim_{n \to \infty} \left\{\frac{10n/n-6/n}{2n/n-3/n}\right}\\= \lim_{n \to \infty} \left\{\frac{10-6/n}{2-3/n}\right}\\= \left\{\frac{10-6/\infty}{2-3/\infty}\right}\\= \frac{10-0}{2-0}\\= 10/2\\= 5[/tex]
Since the limit of the sequence gives a finite value, hence the sequence converges
The ratio of the sides of two similar polygons is 3:2. The area of the smaller polygon is 24cm squared. What is the area of larger polygon
Answer: 36cm
Step-by-step explanation:
From the question, we are informed that the ratio of the sides of two similar polygons is 3:2 and that the area of the smaller polygon is 24cm squared.
Therefore, the area of the larger polygon would be calculated as:
= 24cm ÷ 2/3
= 24cm × 3/2
= 36cm

solve the following equation for x (linear equation):
[tex]\frac{b-cx}{a} + \frac{a-cx}{b} + 2 = 0[/tex]
Answer:
[tex]\displaystyle x=\frac{a+b}{c}[/tex]
Step-by-step explanation:
Equations
Solve the equation:
[tex]\displaystyle \frac{b-cx}{a}+\frac{a-cx}{b}+2=0[/tex]
Subtracting 2:
[tex]\displaystyle \frac{b-cx}{a}+\frac{a-cx}{b}=-2[/tex]
Multiply by ab to eliminate denominators:
[tex]\displaystyle ab\frac{b-cx}{a}+ab\frac{a-cx}{b}=-2ab[/tex]
Simplifying:
[tex]b(b-cx)+a(a-cx)=-2ab[/tex]
Operating:
[tex]b^2-bcx+a^2-acx=-2ab[/tex]
Subtracting [tex]b^2+a^2[/tex]
[tex]-bcx-acx=-2ab-b^2-a^2[/tex]
Multiplying by -1:
[tex]bcx+acx=2ab+b^2+a^2[/tex]
Factoring:
[tex]c(b+a)x=2ab-b^2+a^2[/tex]
The right side of the equation is the square of a+b:
[tex]c(b+a)x=(a+b)^2[/tex]
Simplifying (for a ≠ -b):
[tex]cx=(a+b)[/tex]
Dividing by c:
[tex]\boxed{\displaystyle x=\frac{a+b}{c}}[/tex]

the function c(x)=18x-10 represents the cost in dollars. How many tickets can you buy?
Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.
So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 188 dollars.
The solution would still clear your concept though.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]c(x)=18x-10[/tex]
The slope-intercept form of the line equation
We know that the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
so
comparing with the slope-intercept form of the line equation
here:
rate of change = 18 c(x) or y represents the costand
'x' represents the number of tickets
Assuming the total cost i.e. c(x) = $188
In order to determine the value of x, set c(x) = 188
i.e.
188 = 18x -10
switch sides
188x - 10 = 170
add 10 to both sides
18x - 10 + 10 = 188 + 10
18x = 198
Divide 18 to both sides
18x/18 = 198/18
x = 11
Therefore, if you can buy x = 11 tickets if you pay 170 dollars.

A mail order company charges 4.5% for shipping and handling. If the total order is 54.34 how much was the order total before shipping? Write an equation
Answer:
$52
Step-by-step explanation:
Given that :
Amount charged for shipping and handling = 4.5%
Let cost of order = x
Total amount charged = 54.34
However,
total. Amount charged = (total cost + handling and shipping)
54.34 = x + 0.045x
54.34 = 1.045x
Order total before shipping = 54.34 / 1.045
Order total before shipping = 52
Sheldon works at the coffee shop every Tuesday and he gets paid $15, plus $0.25 for each cup of coffee he sells. This weekend, he wants to make enough money to purchase a kayak, to go out on the lake. He knows that the kayak will cost $50.75 including tax. How many cups will he need to sell to earn enough to buy the kayak?
(please and thank you! -w- )
Answer:
Sheldon has to sell at least 143 cups of coffee to purchase the kayak.
Step-by-step explanation:
First write an expression:
15 + 0.25x ≥ 50.75
Next use inverse operations:
15 + 0.25x - 15 ≥ 50.75 - 15
0.25x ≥ 35.75
0.25x ÷ 0.25 ≥ 35.75 ÷ 0.25
x ≥ 143
Sheldon has to sell at least 143 cups of coffee to purchase the kayak.
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
Answer:
143 cups
Step-by-step explanation:
Sheldon gets a flat $15, as well as 25 cents for each cup of coffee made.
He needs $50.75 to buy a Kayak.
Set the equation. Let the amount of cups of coffee = c.
0.25c + 15 = 50.75
Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, subtract 15 from both sides of the equation:
0.25c + 15 = 50.75
0.25c + 15 (-15) = 50.75 (-15)
0.25c = 50.75 - 15
0.25c = 35.75
Next, divide 0.25 from both sides of the equation:
(0.25c)/0.25 = (35.75)/0.25
c = 35.75/0.25
c = 143
Sheldon will need to sell 143 cups of coffee.

The graph of the absolute value parent function, fx) = [xl, is stretched
horizontally by a factor of 6 to create the graph of g(x). What function is g(x)?
O A. g(x) = (x+61
B. g(x) = 6] x1
O c. g(x) = \šal
D. g(x) = 16x1
Answer:
g(x) = [x/6]
Step-by-step explanation:
The given graph is f(x)=[x]
On stretching the function f(x) by a factor of 6, the new function g(x) is
g(x) = f(x/6)
So, g(x) = [x/6]
Hence, on stretching the f(x) by a factor of 6, the new function g(x)=[x/6].

Translate a point (x, y) 3 units left and 5 units up. Then translate the image 5 units right and 2 units up. What are the coordinates
of the point after the translations?
The coordinates are
Answer:
Please check the explanation.
Step-by-step explanation:
Given the point
P(x, y)
Please note that when we translate a point 'c' units left, the 'c' units are subtracted from the x-values, and when translating a point 'c' units right, we add the 'c' units to the x-values.
Also, note that when we translate a point 'c' units down, the 'c' units are subtracted from the y-values, and when translating a point 'c' units up, we add the 'c' units to the y-values.
After First Translation:
3 units left and 5 units up
P(x, y) → P'(x-3, y+5)
After Second Translation:
Translate the image 5 units right and 2 units up.
P'(x-3, y+5) → P''(x-3+5, y+5+2) = P''(x+2, y+7)
Thus, the coordinates of the point(x, y) after the translations are: P''(x+2, y+7)
TAKING AN EXAMPLE
Let us consider that point
P(0, 0)
After First Translation:
3 units left and 5 units up
P(0, 0) → P'(0-3, 0+5) = P'(-3, 5)
After Second Translation:
Translate the image 5 units right and 2 units up.
P'(-3, 5) → P''(-3+5, 5+2) = P''(2, 7)
Thus, the coordinates of the point P(0, 0) after the translations are:
P''(2, 7)Answer: P''(2, 7). (hope this is what you wanted)!

The simplified form is [tex]x^{\frac{2}{3} }[/tex]
Step-by-step explanation:
So before solving this question we need to know that.....
[tex]\sqrt[6]{x}[/tex] = [tex]x^{\frac{1}{6} }[/tex]
(proof)
[tex]\sqrt[6]{x}[/tex] = [tex]x^{\frac{1}{6} }[/tex]
[tex](\sqrt[6]{x}) ^{6}[/tex] = [tex](x^{\frac{1}{6} })^{6}[/tex]
x = x

4) The given figure shows ∆ABC. Points D,E and F are the mid-points of sides AB,AC and BC respectively. Sides AB, BC and CA measure 6 cm, 10 cm and 8 cm respectively. What is the area of ∆DEF? *
Answer:
the area of ∆DEF = 6 cm²
Step-by-step explanation:
The midpoint theorem states that the line segment connecting the midpoints of two sides of a triangle is parallel to the third side and is congruent to one half of the third side.
DE // BC and DE = BC/2 = 10/2 = 5
same reason: DF = AC/2 = 4
FE = AB/2 = 3
DF² + FE² = 16 + 9 = 25 = 5² = DE²
by the Pythagorean theorem, ΔDFE is a right triangle
area ΔDEF = (3 x 4) / 2 = 6 cm²
