Find the selling price of an $25 item after a 20% markup.
Hello!
Answer:[tex]\boxed{ \bf The~marked~up~price~is~$30.}[/tex]The price will be $30.
Explanation:To find the selling price, we must calculate 20% of $25 and add it to the price.
20% = 0.20
25 × 0.20 = 5
Add this number to the price of the item.
25 + 5 = 30
Answer:
$30
Step-by-step explanation:
$25 item
Markup = Increase
The $25 is increased by 20%
Write 20% as a decimal
Decimal = % / 100
20/100 = 0.2
Multiply 0.2 by 25
0.2(25) = 5
We know that the price that it was marked up is $5
Add this to the original amount ($25) to find the final price after being marked up.
$25 + $5 = $30

What’s - 46.15 as a mixed number
Answer: -46 15/100
Explanation: (see pic attached)
Answer:
46 3/20
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
46.15=46.15/1
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10^2 = 100
46.15/1 x 100/100= 4615/100
Find the Greatest Common Factor (GCF) of 4615 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5
4615/100 divided by 5/5= 923/20
Simplify the improper fraction
46 3/20
In conclusion
46.15= 46 3/20

A farmer sells 8.7 kilograms of pears and apples at the farmer's market. 2 5 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?
Answer: 5.22kg
Step-by-step explanation:
From the question, a farmer sells 8.7 kilograms of pears and apples at the market. Of the pears and apples sold, 2/5 of this weight is pears, and the rest is apples. To calculate the kilograms of apple sold goes thus:
Total kilograms sold = 8.7kg
Fraction of pears weight = 2/5
Pears kilograms sold = 2/5 × 8.7
= 0.4 × 8.7
= 3.48kg
Since the kilograms of pears sold is , 3.48kg, to get the kilograms of apple sold, we subtract 3.48kg from 8.7kg. This will be:
= 8.7kg - 3.48kg
= 5.22kg

Find the midpoint of a line segment starting from the origin and ending at (–8, 0).
Question 6 options:
A)
(0, 0)
B)
(–16, 0)
C)
(0, –4)
D)
(–4, 0)
Answer:
Option D
-4, 0
Step-by-step explanation:
We will first of all identify the coordinates we are dealing with here.
The coordinates for this question (x,y) are: (0,0) and (-8,0)
The next thing we will do is get the formula for finding mid points of line segments.
This is [tex](\frac{x_{1}+x_{2}}{2}, )(\frac{y_{1}+y_{2}}{2}, )[/tex]
Next we will substitute the values of x 1 ,x 2, y 1, and y 2 into the equation.
We will have
[tex](\frac{0+(-8)}{2}, )(\frac{0+0}{2}, )=(-4, 0)[/tex]
Hence the coordinates of the midpoint is (-4,0)

Which is the graph of x^2/9 + y^2/4 = 1
Answer:
Step-by-step explanation:
it is an ellipse.
The graph of the ellipse (x²/3²) + (y²/2²) = 1 is given in the image below.
What is an ellipse?An ellipse is a closed curve in a plane that is symmetric around two perpendicular lines known as the ellipse's axis.
The given equation is in the standard form of the equation of an ellipse centered at the origin with its major axis on the x-axis and its minor axis on the y-axis:
(x²/3²) + (y²/2²) = 1
The square of the semi-major axis (a) is 3² = 9, so the semi-major axis is a = 3.
The square of the semi-minor axis (b) is 2² = 4, so the semi-minor axis is b = 2.
Therefore, the characteristic of the given ellipse is:
a²- b² = 9 - 4 = 5
So the characteristic of the ellipse is 5.

Expressions can be represented as equations or inequalities or neither.
The required expression is: 7 * 52 - 6
7 times the quantity of 52 means 7 * 52
More than 6 means we subtract 6 from 7 * 52
So, we have:
7 * 52 - 6
Hence, the expression that shows 7 times the quantity of 52 more than 6 is: 7 * 52 - 6
