A company charger shipping fee that is 4.5% of the purchase price for all items it ships. What is the fe to ship an item that costs $56
Answer:
This is an percentage change question, by any chance you have a maths textbook, look for units that contains the topic: Percentage Change. Now, let's get solving! :)
Step-by-step explanation:
Firstly, you must multiply 4.5% with 56. That is: shipping fees x purchase price
That gives ($) 2.52 (this is your answer)
No addition/totaling needed as the question asked ONLY for the shipping fees.

What is the equation of the line that passes through the point (5,3) and has a slope of -4/5
The equation of the line that passes through the point (5,3) and has a slope of -4/5 is,
⇒ 4x + 5y = 35
Here,
The given point is (5, 3) and slope is -4/5.
We have to find the equation of the line that passes through the point (5,3) and has a slope of -4/5.
What is Equation of line?
The equation of the line that passes through the point (a, b) and has a slope of m is;
⇒y - a = m (x - b)
Now,
The given point is (5, 3) and slope is -4/5.
Hence, The equation of the line that passes through the point (5,3) and has a slope of -4/5 is;
y - 3 = -4/5 (x - 5)
5 (y - 3) = -4 (x - 5)
5y - 15 = -4x + 20
4x + 5y = 20 + 15
4x + 5y = 35
Therefore, The equation of the line that passes through the point (5,3) and has a slope of -4/5 is
⇒ 4x + 5y = 35.

The sum of three times a number and a second number is five. two times the first number added to the second number is 10. find the two numbers.
Answer:
-5 , 20
Step-by-step explanation:
Forming system of linear equations and solving:Let x and y be the first and second number respectively.
3x + y = 5 -------------(i)
y = 5 - 3x
2x + y = 10 -------------(ii)
Method used for solving: substitution method.
Substitute y = 5 - 3x in equation (ii)
2x + 5 - 3x = 10
2x - 3x + 5 = 10
Combine like terms,
-x + 5 = 10
Subtract 5 from both sides,
-x = 10 - 5
-x = 5
Multiply the entire equation by (-1)
[tex]\sf \boxed{\bf x = -5}[/tex]

The formula to convert a temperature in degrees Fahrenheit (°F) to degrees Celsius (°C) is C = 5/9(F - 32). a. Solve the formula for F. Justify each step. b. Make a table that shows the conversion to Fahrenheit for each temperature: 0°C, 20°C, 32°C, and 41°C. c. Use your table to graph the temperature in degrees Fahrenheit as a function of the temperature in degrees Celsius. Is this a linear function?
a) F = (9/5)*C + 32
b)
0°C = 32°F 20°C = 68°F32°C = 89.6°F41°C = 105.8°Fc) The graph can be seen below, it is a linear function.
How to solve the formula for F?We have the formula:
C = (5/9)*(F - 32)
To solve it for F, we need to isolate the F in the formula:
F = (9/5)*C + 32
b) Now we want to convert some temperatures.
If C = 0° celcius, then:
F = (9/5)*0 + 32 = 32
This means that: 0°C = 32°F
if C = 20° Celcius, then:
F = (9/5)*20 + 32 = 68
then 20°C = 68°F
if C = 32°C then:
F = (9/5)*32 + 32 = 89.6°
So 32°C = 89.6°F
Finally, if C = 41°C then:
F = (9/5)*41 + 32 = 105.8
Then 41°C = 105.8°F
c) Here the function is:
F = (9/5)*C + 32
This clearly is a linear function, and the graph can be seen in the image below.

what is the value of x ?
The value of x in the shape is 111
How to determine the value of x?The shape is a heptagon
This is so because the shape has 7 sides
i.e. n = 7
The sum of angles in the shape is
Sum = 180(n - 2)
So, we have
Sum = 180(7 - 2)
Evaluate
Sum = 900
Also, the sum of angles in the shape is
Sum = x + 120 + 158 + 126 + 125 + 121 + 139
This gives
Sum = x + 789
So, we have
x + 789 = 900
Evaluate the like terms
x = 111
Hence, the value of x in the shape is 111

Three students failed their last test. If 12% of the class failed, how many students are in the class?
Answer:
There are 25 students in the class.
Step-by-step explanation:
Let x be the number of students in the class
12% failed and the number of students is 3
x*12% = 3
x*.12 = 3
Divide each side by .12
x * .12 /.12 = 3/.12
x =25
There are 25 students in the class
Answer:
25 students.
Step-by-step explanation:
12% is 3 students.
100% is the number of students in the class.
3 times 100 divided by 12 is 25.
So there are 25 students in the class.
The weight y of a object on Jupiter is proportional to the weight x of the object on earth. An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter. Write a equation the situation then determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth.
Answer:
5.02 pounds
Step-by-step explanation:
y = k*x
Where,
y = weight of a object on Jupiter
x = weight of the object on earth
k = constant of proportionality
An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter.
y = k*x
378.2 = k*150
378.2 = 150k
k = 378.2/150
= 2.5213
Approximately k = 2.52
determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth
y = k*x
12.64 = 2.52*x
12.64 = 2.52x
x = 12.64 / 2.52
= 5.0159
Approximately x = 5.02 pounds

If a fair die is rolled once, what is the probability of one
An odd number
A number greater than 2
A square number?
Answer:
A fair die has 6 sides.
There are 3 odd numbers on a fair die so the probability would be 3/6
There are 4 numbers greater than 2 on a fair die o the probability of that would be 4/6
There is only one number that will make it square and that is 4. So the probability would be 1/6
solve each system of linear equations by substitution x+y=3 -x+y=5
Answer:
x = -1, y = 4
Step-by-step explanation:
x + y = 3
-x + y = 5
This means that y = 3 - x
We can substitute this value into the equation
-x + y = 5
-x + 3 - x = 5
3 - 2x = 5
Subtract 3 from both sides
-2x = 2
Divide both sides by -2
x = -1
Plugging this number into the equation, we have:
-1 + y = 3
Add 1 to both sides
y = 4
What is the main purpose of the dual accounting method? A. To help you think twice about purchases B. To help you double check what you are spending your money on by confirming all receipts C. To record every transaction twice, reflecting them in accounts and in your budget D. To help detect errors in your budget
Answer: D. To help detect errors in your budget
Step-by-step explanation:
The main purpose of the double entry system is to ensure that errors are detected. If we used only single entry, once a mistake was made, tracing it would be difficult. Using double entry however, we would be able to look for the corresponding entry to see what the error was.
For instance, say a company sells a computer for $440 cash. The bookkeeper however recorded this as $404 in the Cash receipts journal and $440 in the Sales journal. Because it was recorded correctly in the Sales journal, the mistake in the Cash receipts journal can be found and corrected.
