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.
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.

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.

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
10 3/5 ÷ 1/4 = 53/5 ÷ 1/4
= 53/5 x 1/4

= 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.

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 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.

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.

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.
