A pair of jeans is on sale for 20% off. The sale price is $55.00. What is the original amount of the pair of jeans?
Answers
Answer: 275$
I'm not entirely sure I did this right! But at least try!!!
Step-by-step explanation:
20/100 = 55/x (cross multiply)
20x = 5,500 (divide)
X = 275
The original price of the pair of jeans is $ 68.75
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The sale price of the jeans = $ 55.00
The discounted percentage of the pair of jeans = 20 %
Let the original price of the jeans be = A
To calculate the original price of the jeans ,
Original price of the jeans A will be discounted percentage less than and is equal to the sale price of the jeans
So ,
Original price of the jeans A - discounted percentage of the pair of jeans = Sale price of the jeans
And ,
A - ( 20/100 ) A = 55
( ( 100A - 20A ) / 100 )A = 55
(80/100 ) A = 55
( 4/5 ) A = 55
Multiply by 5/4 on both sides , we get
A = ( 55 x 5 ) / 4
A = 275/4
A = $ 68.75
Therefore , Original price of the jeans A = $ 68.75
Hence , the original price of the jeans is $ 68.75

Write in scientific notation: × The United States paid Russia approximately for Alaska.
Answers
Answer:
$7.198 * 10^6
Step-by-step explanation:
Given that :
Total Area of Alaska = 5.9 * 10^5 mi²
Cost of Alaska per square mile = $12.20
Total amount paid to purchase Alaska:
(Total area in square miles * Cost per square mile)
(5.9 × 10^5) * $12.20
(5.9*12.20) * 10^5
71.98 * 10^5 dollars
= $7.198 * 10^6
Hence, amount the United States paid Russia for the purchase of Alaska is approximately $7.198 * 10^6

Robert started to save money to purchase a new game console. His savings at the end of the first week included a jar of 368 nickels and dimes. The total value of the coins was $24.40. Which system of equations below would be the best to use to find the number of nickels and dimes Anthony had at the end of the first week?
a. n+ d = 368
5n + 10d = 24.40
b. n+ d = 24.40
0.05n + 0.10d = 368
c. n + d = 368
0.05n + 0.10d = 24.40
d. n + 9 = 368
0.5n + 0.10d = 24.40
Answers
Answer:
0.05n + 0.10 d =24.40
Step-by-step explanation:
Nickel is worth 0.05 of a dollar(1)
The system of equations below would be the best to use to find the number of nickels and dimes Anthony had at the end of the first week is:
n + d = 368
0.05n + 0.10d = 24.40
The number of nickels and dimes Anthony saved at the end of the first week can be determined using two equations. This is known as simultaneous equations.
The total number of nickels and dimes in the jar is 368. This can be represented with the equation:
nickels + dimes = 368
n + d = 368. This would be the first equation.
A nickel is equal to 0.05 of a dollar and a dime is equal to 0.1 of a dollar. The total sum of money in the jar is $24.40. This means that the value of dimes and nickels in the jar is $24.40. This can be represented with the equation: 0.05n + 0.10d = 24.40. This is the second equation.

The length of a rectangle board is 10 centimeters longer than its width. The width of the board is 26 centimeters. The board is cut into 9 equal pieces. What is the area of each piece? What are the possible dimensions of each piece? (Take the dimensions to be whole numbers.)
Answers
Answer:
Area of each piece = 104 [tex]cm^{2}[/tex]
Possible dimensions are 26 cm by 4 cm, 13 cm by 8 cm.
Step-by-step explanation:
Given that:
Dimensions of the rectangular board as:
Length of the board is 10 cm longer than its width.
Width of the board = 26 cm
Length of the board = 26 + 10 = 36 cm
The rectangular board is divided into 9 equal pieces.
To find:
Area of each piece and
the possible dimensions of each piece = ?
Solution:
First of all, let us calculate the area of bigger rectangular board.
Area of a rectangle is given by the following formula:
[tex]Area = Length \times Width[/tex]
Area = 26 [tex]\times[/tex] 36 [tex]cm^2[/tex]
Area of each smaller rectangle = [tex]\frac{26\times 36}{9} = 104\ cm^2[/tex]
To find the possible dimensions, we need to find the factors of 104.
104 = 26 [tex]\times[/tex] 4
104 = 13 [tex]\times[/tex] 8
Therefore, the Possible dimensions are 26 cm by 4 cm
and
13 cm by 8 cm.

Find the values of x in [0, 360°) which satisfy the
equation below.
2 cota x = -3 SC X
Answers
Given :
An equation 2cot x = -3sec x .
To Find :
the values of x in [0, 360°) which satisfy the given equation.
Solution :
Converting cot x and sec x in the form of sin x and cos x.
[tex]\dfrac{2cos \ x}{sin\ x}= \dfrac{-3}{cosx}\\\\2cos^2 x +3 sin\ x =0\\\\2( 1 - sin^2 x ) + 3sin \ x = 0 \\\\2sin^2 x -3sin\ x -2 = 0\\\\2sin^2\x -4sin\ x + sin\ x -2 = 0\\\\2sin\ x( sin\ x - 2 )+ 1( sin \ x - 2 ) = 0\\\\sin \ x = \dfrac{-1}{2} \ or\ sin \ x = 2[/tex]
Neglecting sin x = 2 because sin x cannot be greater than 1.
x = π - π/6, π + π/6
x = 5π/6 and x = 7π /6
Therefore, the values of x in [0,360°) is 5π/6 and x = 7π /6 .

Sara wants to find the input value that produces the same output for the functions represented by the tables.
A table headed with f(x) equals negative 0.5 x plus 2, with 2 columns and 8 rows. The first column, x, has the entries, negative 3, negative 2, negative 1, 0, 1, 2, 3. The second row, f(x), has the entries 3.5, 3, 2.5, 2, 1.5, 1, 0.5. A table headed with g(x) equals 2 x minus 3, with 2 columns and 8 rows. The first column, x, has the entries, negative 3, negative 2, negative 1, 0, 1, 2, 3. The second row, g(x), has no entries.
What is the input value that produces the same output value in both charts?
–2

Answers
Answer:
2 is the value that provides the same result with f(x) and g(x).
Step-by-step explanation:
You can solve this by saying:
f(x) = g(x)
and then solving for x.
So let's do it:
[tex]f(x) = g(x)\\-0.5x + 2 = 2x - 3\\2x + 0.5x = 2 + 3\\2.5x = 5\\x = 2[/tex]
This tells us that when x = 2, the two functions will have identical values. Let's try them out to confirm it!
f(x) = -0.5x + 2
f(2) = -0.5 * 2 + 2
f(2) = -1 + 2
f(2) = 1
g(x) = 2x - 3
g(2) = 2 * 2 - 3
g(2) = 4 - 3
g(2) = 1
So we can see that 2 is the value that produces the same result in both charts.
The input value that produces the same output value in both charts is 2. so the correct answer is option D.
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

We will put the points and will find the value of functions:-
g(-3) = 2(-3) - 3 = -6 -3 = -9
g(-2) = 2 -(-2) -3 = -7
g(-1) = 2( -1) -3 = -3
g(0) = 2 - 0 - 3 = -3
g(1) = 2.1 - 3 = -1
g(2) = 2.2 -3 = 1
