Given : Molly bought a pair of Gloves which cost £4
Given : Molly sold the Gloves and Skirt for a Total of £48
Given : Molly made 100% Profit on the Cost of the Gloves
⇒ Molly sold the Gloves at a Cost of £8
Selling Price of Gloves + Selling Price of Skirt = £48
⇒ £8 + Selling Price of Skirt = £48
⇒ Selling Price of Skirt = £40
Given : Molly made 20% Profit on the Total Cost

The figure shows five points. A point has been translated right and up
A point has been translated right and up from point D could be the image of B.
It indicates that a point was translated right and up.
As a result, any point existing on the rightmost side cannot be the translated point.
As a result, points E and D are ruled out.
There is no point that is higher than point A.
As a result, no "up" translation is available for point A.
Only points C and B are capable of "right and up" movement.
As a result, the first option "Point D could be the image of B" is correct.

Your housing and fixed expenses are $685.70/month. If they are 33% of your realized income, how much is your realized income per month?
a) $2,077.88
b) $2,790.55
c) $2,219.91
d) $2,488.16
Answer:
Option a. $2077.88 is the correct answer.
Step-by-step explanation:
Your housing and fixed expenses are $685.70 per month.
If they are 33% of your realized income.
Let your realized income per month be x
33% of x = $685.70
[tex]\frac{33}{100}[/tex] of x = 685.70
0.33x = 685.70
x = 685.70 ÷ 0.33 = 2,077.8787 rounded to $2,077.88
Your realized income per month would be $2,077.88.

16.45 markdown 33% what’s the anwser
dude, use a calculator
Step-by-step explanation:
Answer:
= 11.02
Step-by-step explanation:
Firstly, we need to find the percentage of the amount left first. This can be done by subtracting the percentage from 100:
100 - 33 = 67
To find the percentage of something, you need to use the following equation:
Amount x [tex]\frac{percentage}{100}[/tex]
Simply plug the given values in:
16.45 x [tex]\frac{67}{100}[/tex] = 11.02
So the answer is 11.02!
Julia is allowed to watch no more than 5 hours of telivison a week. So far this week, she has watched 1.5 hours. write and solve an inequality to show how many hours of teli she can watch this week. ( can u show your work along with it? )
Answer:
she can watch 3.5 hours this week.
Step-by-step explanation:
Julia is allowed to watch no more than 5 hours of television a week.
Let x be the number of hours she can watch per week
number of hours not more than 5 hours
so x<=5
She already watched 1.5 hours. so inequality becomes
x+ 1.5 <= 5
Now we solve for x
subtract 1.5 on both sides
x + 1.5 < = 5 - 1.5
x < = 3.5
So, she can watch 3.5 hours this week.

Which equation is a point slope form equation for line AB?
a) y−2=−2(x+6)
b) y−2=−2(x+2)
c) y−6=−2(x+2)
d) y−2=2(x+2)
Answer:
the answer is c
Step-by-step explanation:
Answer:
c) y−6=−2(x+2)
Step-by-step explanation:
The general point slope form equation is:
y - y1 = m*(x - x1)
where x and y are the variables, (x1, y1) is the coordinate of a point on the line and m is the slope of the line.
To calculate the slope of the line we need two points on the line (x1, y1) and (x2, y2) and the following equation:
m = (y2 - y1)/(x2- x1)
Coordinates of point A: (-2, 6)
Coordinates of point B: (2, -2)
Replacing into the equation:
m = (6 - (-2))/(-2 - 2)
m = 8/(-4)
m = -2
Replacing this value and coordinate of point A into the general point slope equation we get:
y - 6 = -2*(x - (-2))
y - 6 = -2*(x + 2)

A storeowner orders 25 calculators that cost $48 each. The storeowner can sell each calculator for $60. The storeowner sold 22 calculators to customers. He had to return 3 calculators that were never sold and pay a $2 charge for each returned calculator (although the initial cost is refunded). What is the storeowner's profit?
25*48=1,200
So we start at -1,200
22*60=1,320
So currently we are at a profit of $120.
120-6=114
Total profit: $114
As per the given values, the storeowner's profit is $114.
Explanation:Total number of calculators = 25
Cost of calculators = $48
The amount at which they can be sold = $60.
To calculate the storeowner's profit, we need to consider the total cost and total revenue.

Anyone know? Will mark brainliest if correct!
The answer is A. g(x).
Here's why:
f(x) = -x^4 - 2: This function is a downward-facing parabola (due to the negative coefficient of x^4) with a maximum y-value at its vertex. The vertex occurs at x = 0, and the maximum y-value is f(0) = -2.
g(x) = -3x^3 + 2: This function is a cubic function with a local maximum, but it does not have a global maximum. However, its maximum value is still greater than the maximum value of f(x).
Key points:
The maximum y-value of f(x) is limited to -2 because of the negative leading coefficient and the constant term of -2.
g(x) doesn't have a defined maximum y-value, but it can reach values greater than -2, making its maximum value larger than that of f(x).
Therefore, g(x) has the largest maximum y-value among the two functions.

A recipe calls for 40 ounces of meat.How many pounds of meat does the recipe require?
Answer: 40 ounces=2.5 pounds
Step-by-step explanation:
Since 1 pound=16 ounces. You have to see how many times 16 goes into 40, it goes in forty 2 times with 8 left over so that means we need decimal, since 8 is half of 16 the answer is 2.5.
Final answer:
To convert 40 ounces of meat to pounds, divide by the unit equivalence of 16 ounces per pound, resulting in 2.5 pounds of meat needed for the recipe.
Explanation:
The student is asking how many pounds are equivalent to 40 ounces of meat. To find the answer, you will need to know the unit equivalence between ounces and pounds.
The unit equivalence is 1 pound = 16 ounces. Therefore, to convert ounces to pounds, you divide the number of ounces by the unit equivalence.
Converting 40 ounces to pounds:
Start with the given amount in ounces: 40 ounces.Use the unit equivalence: 1 pound = 16 ounces.Divide 40 ounces by 16 ounces per pound to find the number of pounds.40 ounces ÷ 16 ounces/pound = 2.5 pounds
So, the recipe requires 2.5 pounds of meat.
Which value is the same as 2 tenths?
2 tenths is equal to 0.2 in decimal format. This is derived from its fraction format, 2/10, and its place value in the base-ten number system, which is a 'tenths' place.
Explanation:In mathematics, the value that is equivalent to 2 tenths is 0.2. This is because when we say 'tenths', we are referring to a fractional or decimal value that has a denominator of ten in the context of fractions or one place after the decimal point.
Therefore, 2 tenths is essentially 2 divided by 10 which equals 0.2 in decimal format. We can further illustrate this using a base-ten number system. In this system, each place to the right of the decimal point represents a 'tenths' place value. Therefore, in the number 0.2, the digit '2' is in the 'tenths' place.

Dan wants to make 12 pancakes but what quantity of each ingredient should he use for 240g plain flour,2 eggs and 600ml milk?
To make 12 pancakes, Dan should use 20g of plain flour, 2 eggs, and 50ml of milk.
Explanation:To determine the quantity of each ingredient needed to make 12 pancakes, we can use the ratio of ingredients given in the recipe:
240g plain flour : 2 eggs : 600ml milk
To find the quantity of plain flour needed for 12 pancakes, we can set up a proportion:
240g / x = 12 / 1
Cross multiplying, we get:
x = (240g * 1) / 12
x = 20g
Therefore, Dan should use 20g of plain flour for 12 pancakes. Similarly, he should use 2 eggs and 50ml of milk for 12 pancakes.

Write the expression 6a-2(a-1) in simplest form
Final answer:
To simplify the expression 6a - 2(a - 1), distribute the -2 across the terms inside the parentheses, and then combine like terms to get the simplest form, which is 4a + 2.
Explanation:
To simplify the expression 6a - 2(a - 1), you need to distribute the -2 across the terms inside the parentheses and then combine like terms. Here's the process step by step:
Distribute the -2 to both a and -1 inside the parentheses: -2 x a gives us -2a, and -2 x -1 gives us +2.Write out the new expression without parentheses: 6a - 2a + 2.Combine like terms by subtracting -2a from 6a, which results in 4a.Add the constant term 2 to get the final simplified expression: 4a + 2.The simplest form of the expression is 4a + 2.
