This year, Farah's car is worth $22,000. If the value of Farah's car decreases by 8%, what will her car be worth next year?
Answers
Answer:
$20,240
Step-by-step explanation:
Multiply 22,000 by 0.92% since if you subtract 0.08 which is equivalent to 8% from 1, you would need that percentage to get to your final answer which is $20,240.
Another option is to do the same thing except multiply 22,000 by 0.08% in which $1,760 is being cut off as it decreases. Subtract that number from $22,000 to get the same answer mentioned earlier.
Answer:
$20,240
Step-by-step explanation:
This is a simple interest formula.
$22,000*(8%/100%) = $1760
$22,000-$1760 = $20,240

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

Work = Force × distance = 500 × 15 = 7,500 J.
Hope this helps! Merry Christmas and Happy New Year!
Total work done by pushing the car for a distance of 15 m using a force of 500 N is 7500 Joule.
What is total work done?The total work done can be derived in terms of the products of force applied and the total distance covered.
Therefore,
Total work done = force × distance = 500 × 15 N-m = 7500 Joule
Hence, 7500 Joule work is done.

Answers
Step-by-step explanation:
Quesion 1
The cost of one chair can be found by dividing the cost of the total chairs by the number of chairs
hence, cost per chair= 150/50= $3 per chair
Question 2
let us find the number of walnuts per bag
= 330/6
=55 walnuts per bag
hence in two bags there will be 55*2= 110 walnuts

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
Answer:
1. Write the expression: (5.9 × 105)(12.2)

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
–1

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.
here, we have,
You are given two functions f (x) = -0.5X +2 and g(x) = 2x - 3
x f(x)
-3 3.5
-2 3
-1 2.5
0 2
1 1.5
2 1
3 0.5
The second table is given below:-
x g(x)
-3
-2
-1
0
1
2
3
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
g(3) = 2.3 -3 = 3
Hence the second table will be
x g(x)
-3 -9
-2 -7
-1 -5
0 -3

The input value that produces the same output value in both charts is 2.

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.

Write and solve an equation to work out the price of an adult ticket
Answers
hope it helps!!!!
please mark brainliest
Answer:
The price of adult ticket is £38.
Step-by-step explanation:
First, you have to form equations in terms of a (adult) and c (child) :
[tex]2a + 4c = 152 - - - (1)[/tex]
[tex]a = 2c - - - (2)[/tex]
Next, you have to solve these equations by substitution :
[tex](2)→(1)[/tex]
[tex]2(2c) + 4c = 152[/tex]
[tex]8c = 152[/tex]
[tex]c = 152 \div 8[/tex]
[tex]c = 19[/tex]
[tex]substitute \: c = 19 \: into \: (2)[/tex]
[tex]a = 2 \times 19[/tex]
[tex]a = 38[/tex]
