The original price of the sweater, before a 20% discount, was found to be $60. This was calculated by dividing the sale price of $48 by 0.80, as the sale price represents 80% of the original price.
Explanation:The student is asking how to find the original price of a sweater given that the sale price is $48 and this sale price represents a 20% discount from the original price.
To find the original price, we need to understand that the sale price is 80% of the original price (100% - 20% discount). Let's denote the original price as P. We can set up the equation P * 0.80 = $48. Solving for P, we get P = $48 / 0.80
The calculation will give us the original price which is $60. The original price of the sweater was $60 before the 20% discount was applied.
Final answer:
The original price of the sweater was $60.
Explanation:
Let x be the original price of the sweater.
According to the given information, the sale price of the sweater is $48, which is 20% less than the original price.
So, we can set up the equation as follows-
Original Price - Discount = Sales Price
x - 0.2x = $48
Simplifying:
0.8x = $48
Dividing both sides by 0.8, we get:
x = $60
Therefore, the original price of the sweater was $60.

The measure of m∠KPN is 68°.
Step-by-step explanation:
From the given diagram, we are given with lines passing through a point P creating different angles.
Data given,
m∠KPN = 4x°.
m∠NPO = (x+5)°.
And m∠KPO= 90°.
The m∠KPO is spitted into m∠KPN and m∠NPO.
Thus the sum of m∠KPN and m∠NPO will be m∠KPO.
⇒m∠KPN + m∠NPO =m∠KPO.
Substitute the values to find x value.
4x°+(x+5)°= 90°.
(°5x+5)=90°.
5x°=90°-5°.
5x°=85°.
x=[tex](\frac{85}{5} )[/tex].
x= 17.
⇒m∠KPN = 4x°.
=4(17)°.
m∠KPN =68°.
Thus the measure of m∠KPN is 68°.

What is 1 1/3 times 1 4/9 in fraction form
Answer:
52 / 27
Step-by-step explanation:
To multiply mixed numbers, convert them into improper fractions. Multiply the two improper fractions together and simplify the result.
Explanation:To multiply mixed numbers, we first convert them into improper fractions. To convert 1 1/3 into an improper fraction, we multiply the whole number (1) by the denominator (3) and add the numerator (1). This gives us 4/3. Similarly, to convert 1 4/9 into an improper fraction, we multiply the whole number (1) by the denominator (9) and add the numerator (4). This gives us 13/9.
Now, we can multiply the two improper fractions together. 1 1/3 times 1 4/9 equals (4/3) * (13/9). To multiply fractions, we multiply the numerators together and multiply the denominators together. So, (4/3) * (13/9) equals (4 * 13) / (3 * 9), which simplifies to 52/27.
Therefore, 1 1/3 times 1 4/9 in fraction form is equal to 52/27.

Multiply the algebraic expression using a Special Product Formula and simplify.
(x − 7y)^2
The simplified expression is x^2 - 14xy + 49y^2.
To multiply the expression (x - 7y)^2 using the Special Product Formula, we can use the formula (a - b)^2 = a^2 - 2ab + b^2.
In this case, a = x and b = 7y. Plugging these values into the formula, we get:
(x - 7y)^2 = x^2 - 2(x)(7y) + (7y)^2
Simplifying further:
= x^2 - 14xy + 49y^2
So, the simplified expression is x^2 - 14xy + 49y^2.
What are the dimensions of the rectangle shown on the coordinate plane? On a coordinate plane, a rectangle has points (1, -1), (10, -1), (10, -5), (1, -5). The base is 3 units and the height is 9 units. The base is 9 units and the height is 4 units. The base is 10 units and the height is 4 units. The base is 11 units and the height is 6 units.
The dimensions of the rectangle shown on the coordinate plane is The base is 9 units and the height is 4 units.
Option: B.
Step-by-step explanation:
We are given with the coordinate points of a rectangle.
The points are (1, -1), (10, -1), (10, -5), (1, -5).
From the given graph, the bigger side is the base and the height is the smaller side.
The points (1, -1), (10, -1) and (1, -5), (10, -5) can be used to find the base of the rectangle.
The points (10, -1), (10, -5) and (1, -1), (1, -5) can be used to find the height of the rectangle.
Let us find the base using coordinate point (1, -5), (10, -5) .
Since the base runs horizontally on the x-axis, we have to find the run.
run = [tex]x_2-x_1[/tex].
run = 10-1.
run (base)= 9 units.
Let us find the base using coordinate point (10, -1), (10, -5) .
Since the height runs vertically on the y-axis, we have to find the rise.
rise = [tex]y_2-y_1[/tex].
rise = -5-(-1).
rise=-5+1.
rise (height)= 4 units. ( Units are always measured in positive.)
∴ The base is 9 units and the height is 4 units.

Find the final price on a $1049 television that is on sale for 12% off if the sales tax is 4.5%
The final price of a $1049 television on a 12% sale, with a 4.5% sales tax, is $964.66.
Explanation:The final price on a $1049 television that is on sale for 12% off can be found by deducting the discount from the original price, and then adding the sales tax on the discounted price.
First, let's find the discount: 12% of $1049 is (12/100)*1049 = $125.88. So, the price after discount would be 1049 - 125.88 = $923.12.
Next, we need to add the 4.5% sales tax. Sales tax is calculated on the discounted price, so 4.5% of $923.12 is (4.5/100)*923.12 = $41.54.
Finally, we add the tax to the discounted price to get the final price: $923.12 + $41.54 = $964.66. So, the final price of the television is $964.66.

A bakery uses ounces of icing for every of a cake. What is the unit rate in ounces of icing per cake?
A.
ounces of icing per cake
B.
ounces of icing per cake
C.
ounces of icing per cake
D.
ounces of icing per cake
Answer:
Here is a similar question:
A bakery uses 10 1/5 ounces of icing for every 1/4 of a cake. What is the unit rate in ounces of icing per cake.
The unit rate in ounces of icing per cake = 40 4/5 ounces
Step-by-step explanation:
Given:
Ounces of ice used for every 1/4 cake = 10 1/5
We have to find the unit rate.
Let the unit rate be 'x' .
Unit rate is the rate when we use unit 'one' as our reference to find any value.
Lets convert the mixed fraction of ounces.
⇒ [tex]10\frac{1}{5} = \frac{(10\times 5)+1}{5} =\frac{51}{5}[/tex]
Portion of the cake used = [tex]\frac{1}{4}[/tex]
To find the unit rate here we must divide :
⇒ [tex]x=\frac{number\ of\ ounces\ used}{portion\ of\ the\ cake}[/tex]
⇒ [tex]x=[/tex] [tex]\frac{51}{5}[/tex] ÷ [tex]\frac{1}{4}[/tex]
⇒ [tex]x=[/tex] [tex]\frac{51}{5}\times \frac{4}{1}[/tex]
⇒ [tex]x=[/tex] [tex]\frac{51\times 4}{5}[/tex]
⇒ [tex]x=[/tex] [tex]\frac{204}{5}[/tex]
⇒ [tex]x=[/tex] [tex]40\frac{4}{5}[/tex] Or [tex]40.8[/tex]
Hence, the unit rate in ounces of icing per cake = 40 4/5 ounces.
Answer:
Another similar question:
A bakery uses 10 3/5 ounces of icing for every 1/4 of a cake. What is the unit rate in ounces of icing per cake?
Step-by-step explanation:
Answer is 42 2/5

= 53/5 x 1/4
= 212/5
= 42 2/5
Two angles are supplementary. The larger angle is 15 more than 10 times the smaller angle. Find the measure of each angle
15° and 165°
Step-by-step explanation:
Step 1 :
Let x and y denote the angles with x as the smaller angle and y as the larger angle
When 2 angles are supplementary, the sum of both the angles is 180 degrees.
Hence x + y = 180
Step 2:
Given that the larger angle is 15 more than 10 times the smaller angle
Hence y = 15 + 10 x
Step 3 :
Solving for the 2 equations we have
11x = 165 => x = 15
=> y = 180-15 = 165
Hence the 2 angles are 15 and 165 degrees.
Given f(x) = x² + 8x and g(x) = x4, choose
the expression for (fºg)(x).
The expression for the new function (fog(x)) = x⁸ + 8x⁴
What is a composite function?
A composite function some called function of a function is a process whereby two functions produce a third function.
Let assume there is a function f(x) and g(x), a composite function fog(x) read as f of g of x, produces a third function h(x).
In the given question, we are to find (fog) (x), we will replace the value of the function g(x) for x in f(x).
i.e.
f(g(x) = x² + 8x
[tex]f(g(x) = (x^4)^2+8(x^4)[/tex]
[tex]f(g(x)) = x^8+8x^4[/tex]
A rectangular bathroom floor is covered with square tiles that are 1 1/2 feet by 1 1/2 feet. The length of the bathroom floor is 10 1/2 feet and the width is 6 1/2 feet
Answer:
The number of square tiles required to cover the bathroom floor is approximately 31.
Step-by-step explanation:
The dimensions of the rectangular floor of the bathroom are:
Length = 10.5 ft.
Breadth = 6.5 ft.
The dimensions of the square tiles are:
Side = 1.5 ft.
The area of the rectangular floor of the bathroom is:
[tex]Area\ of Bathroom\ floor=Length\times Breadth\\=10.5\times6.5\\=68.25[/tex]
The area of 1 square tile:
[tex]Area\ of\ 1\ square\ tile=(SIde)^{2}\\=(1.5)^{2}\\=2.25[/tex]
The number of tiles required to cover the bathroom floor is:
[tex]Number\ of\ tiles=\frac{Area\ of\ bathroom\ floor}{Area\ of\ 1\ square\ tile} \\=\frac{68.25}{2.25}\\ =30.3333\\\approx31[/tex]
Thus, the number of square tiles required to cover the bathroom floor is approximately 31.

Your credit score is 580. Your current credit card limit is $2,000. Your current credit card balance is $1,950. If you shrink your debt balance by 13% each month for 12 months what will your balance be?
Answer:
$366.66
Step-by-step explanation:
You start with a credit card balance of $1950. If you reduce this balance by 13% each month for 12 months, using the formula for geometric series (a(r^n)), your final balance at the end of 12 months will be approximately $452.98.
Explanation:The student's question is asking about reducing a credit card debt balance by a fixed percent each month. In this case, the student is reducing their debt by 13% every month for 12 months. To get a clear picture, let's go through this step by step.
Initially, the credit card balance is $1950. In the first month, the student reduces the debt by 13% which is $253.5. So, the remaining balance at the end of first month would be $1950 - $253.5 = $1696.5
This process is repeated each month. For example, in the second month, the student reduces the new amount of $1696.5 by 13%. The debt will continue to decrease in this manner each month.
To calculate the balance at the end of 12 months, we would use the formula for geometric series: a(r^n), where 'a' is the initial amount of debt($1950), 'r' is the percentage (1 - 13% or 0.87) and 'n' is the number of months (12).
Your final balance at the end of 12 months would be $1950*(0.87^12) which approximately equals $452.98. Hence, by reducing your debt by 13% each month for 12 months, your balance will be approximately $452.98. But remember, maintaining steady payments and not adding to the balance by new purchases is also important in managing credit card debt.
