A salesman bought a computer from a manufacturer. The salesman then sold the computer for $15600 making a loss of 25%. What amount did the salesman pay the manufacturer for the computer?
The amount that the salesman pay the manufacturer for the computer is $20800.
How to calculate the value?From the information, the salesman sold the computer for $15600 making a loss of 25%.
The amount that the salesman pay the manufacturer for the computer will be illustrated thus:
Since a 25% loss was made, the cost price will be: = 100% + 25% = 75%
Therefore, the cost price will be:
= Sales price / 125%
= $15600 / 0.75
= $20800
The amount is $20800.

The diagonal of a square is x units. What is the area of the square in terms of x?
The area of the square is (x²/2) square units.
We are given a square. The length of the diagonal of the square is x units. We have to find the area of the square in terms of "x".
Let the side of the square be denoted by the variable "s". We will use the Pythagorean theorem to find the length of the side of the square.
s² + s² = x²
2s² = x²
s² = x²/2
s = √(x²/2)
s = (x/√2)
The area of the square is given by the square of the side length. Let the area of the square be denoted by the variable "A".
A = s²
A = (x/√2)²
A = x²/2
Hence, the area of the square is (x²/2) square units.

6. Jung purchased several video games priced at $29.95 each and paid $5.95 for express shipping. His total purchase was $185.65. How many video games did he purchase?
Answer:
6 video games
Step-by-step explanation:
We can solve this question with an algebraic equation.
29.95x + 5.95 = 185.65
29.95x + 5.95 - 5.95 = 185.65 - 5.95

Serenity invested $16,000 in an account paying an interest rate of 4. 5% compounded annually. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 9 years?.
The amount of money that would be in the account after 9 years, giving the interest rate and the amount invested is $23, 777.52
How to find the amount in future?The amount in the account after 9 years is called the future value of the amount that Serenity invested.
To find this future value, you use the future value formula which is:
= Amount invested x ( 1 + interest rate) ^ number of years
The amount in the account after 9 years would therefore be:
= 16, 000 x ( 1 + 4.5%) ⁹

I need to know (basically what the picture shows)
Answer:
Step-by-step explanation:
Hi, you are studying trigonometry :P nice
conterminal means stopping at the same place, right? sooo what is the same place for 659° compared to our only once around the circle of 360° since 720° is twice around a circle our 659° is less than that so just subtract 360° from 659° to get the co-terminal angle.
659-360=299°
299° is the co-terminal angle
270 is the line between the 3rd and 4th quadrant, so this is definitely in the 4th quadrant.
let's just count backwards (CW) from zero degrees till we get to our 299° angle going in the forward (CCW) direction. so 299-360= -61°
the reference angle is 61°
Does all of this make sense? :/

1) through: (5, 4) and (-2, 5)
2) through: (4, -5) and (0, 2)
3) through: (0, 4) and (2, 1)
The equation of the line in point slope form is as follows:
y - 4 = - 1 / 7(x - 5)y + 5 = - 7 / 4(x - 4)y - 4 = - 3 / 2(x - 0)How to represent linear equation in slope intercept form?Linear equation can be represented in different form such as point slope form, slope intercept form, standard form and general form.
Therefore, equation in point slope form can be represented as follows:
y - y₁ = m(x - x₁)
where
m = slopeTherefore, let's find the point slope form of the lines.
1) through: (5, 4) and (-2, 5)
m = 5 - 4 / -2 - 5
m = 1 /- 7 = - 1 / 7
Therefore,
y - 4 = - 1 / 7(x - 5)
2) through: (4, -5) and (0, 2)
m = 2 + 5 / 0 - 4
m = 7 / -4 = - 7 / 4
Therefore,
y + 5 = - 7 / 4(x - 4)
3) through: (0, 4) and (2, 1)

. The playground at DeVille Elementary School is square-shaped, and has a perimeter of 600 feet.
What is the length of each side of the playground?
The length of each side of the playground is 150 feet.
Calculating the length of a square-shaped playgroundFrom the question, we are to determine the length of each side of the playground.
From the given information,
The perimeter of a square is given by the formula,
P = 4l
Where P is the perimeter of the square
and l is the length of a side of the square
"The playground at DeVille Elementary School is square-shaped, and has a perimeter of 600 feet."
That is,
P = 600 feet
Now, we will determine the value of l
Substitute the value of P into the equation
P = 4l
600 = 4l
Divide both sides by 4
600/4 = 4l/4
150 = l
Therefore,
l = 150 feet
Hence, the length is 150 feet

Richard’s cumulative gpa for 3 semesters was 2. 0 for 42 credits. His fourth semester gpa was 4. 0 for 14 course units. What is richard’s cumulative gpa for all 4 semesters?.
Richard earned a cumulative GPA of 2.5 in all four semesters.
Here, we know that the cumulative GPA for the first 3 semesters is 2.0
He had earned 42 credits in total in all three semesters.
Cumulative GPA = Total points earned/credits rewarded
Hence,
Total points earned in 3 semestes= 2 X 42
= 84 points
In the fourth semester,
he had earned 14 credits with a GPA of 4.0
Hence total points earned = 4 X 14
= 56 points
Therefore, total points earned in all four semesters = 84 + 56 points
140 points
Total credits = 14 + 42
= 56
Hence, the cumulative GPA of all 4 semesters
= 140/56
= 2.5 points.

y = y coordinate
m = slope
x = x coordinate
b = y intercept
Given,
Here we have the table shows the amount of storage y (in gigabytes) on a music-playing device when there are x songs on the device
Now, we have to find the following:
a) Equation of the table
b) Slope and intercept.
In order to find the equation, we have to identify the slope an intercept of the table.
So, to find that we have to take two points from the table.
Then the selected points are
(0, 16), (242, 14.8)
By using these point we have to calculate the slope as,
m = (14.8 - 16) / (242 - 0)
m = -1.2/242
m = -0.005
Now, the intercept is calculated by using the point (0, 16) and the slope -0.005, then we get,
16 = -0.005(0) + c
c = 16
Therefore, the equation is y = -0.005x + 16.
