A dozen of eggs was brought at N2000. If each egg was sold at N60, find the profit or loss
A dozen = 12
Multiply the prices they were sold for by 12:
12 x 60 = 720
By selling the 12 eggs they made 720
Since they bought it for 2000 they lost money.
2000 - 720 = 1280 loss

Answer:
Distance between Gas Station and House = 7.81 miles.
Step-by-step explanation:
The distance between the two locations is 7.81 miles
Distance between two pointsGiven the point at (4,3) represents the location of her house, and the point at (10, 8) represents the location of the gas station.
The distance between the two locations will be determined using the formula
D [tex]=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute the given coordinate into the formula
[tex]D=\sqrt{(-6)^2+(-5)^2}\\D=\sqrt{(4-10)^2+(3-8)^2}\\D=\sqrt{36+25}\\ D=\sqrt{61}\\ D=7.81miles[/tex]
Hence the distance between the two locations is 7.81 miles

An element with mass 330 grams decays by 25. 5% per minute. How much of the element is remaining after 5 minutes, to the nearest 10th of a gram?.
The amount of mass after 5 minutes is 75.74 grams.
It is given that
The amount initially = 330grams
After every minute mass decays by 25.5%
What is the percentage?The percentage is the value per hundred.
Amount after 1 min = 330-330*25.5/100 = 245.85grams
Amount after 2 min = 245.85-245.85*25.5/100 = 183.16grams
Amount after 3min = 183.16-183.16*25.5/100 = 136.45grams
Amount after 4 min = 136.45-136.45*25.5/100= 101.66grams
Amount after 5 min =101.66-101.66*25.5/100 = 75.74grams
Therefore, the amount of mass after 5 minutes is 75.74 grams.

The figure shows Triangle ABC and some of its transformed images on a coordinate grid:
Which of the four triangles was formed by a translation of Triangle ABC?
1
2
3
4
Answer: Triangle 4
The specific translation or shifting is "move 9 units to the right and 4 units down".
We can prove this by looking at something like point A(-10,2) and note how it moves to (-4,-2). Going from (-10,2) to (-4,-2) is exactly 9 right and 4 down.
In terms of x,y notation the translation rule is [tex](x,y) \to (x+9,y-4)[/tex]

A company manufactures 16-oz boxes of cereal. Boxes are randomly weighted to ensure the correct amount. If the discrepancy in weight is more than 0. 15 oz, the production is stopped. What is the range of acceptable values for production to continue? 15. 15 oz to 16. 00 oz 15. 85 oz to 16. 00 oz 15. 85 oz to 16. 15 oz 16. 15 oz to 16. 45 oz.
The range of acceptable values for production to continue working of the company without stoppage is 15.85 to 16.15.
What is the range of acceptable values?Range is the area of fluctuation between the upper and lower limit. The range of the acceptable values is all the values between the upper and lower limit.
Here, a company manufactures 16-oz boxes of cereal. Now, this boxes are randomly weighted to ensure the correct amount.
As the discrepancy in weight is more than 0.15 oz then the production of the company is stopped.
To proper functioning of the company without stoppage, the limit of the production should be with in 0.15 oz.
The company produce, 16-oz boxes of cereal and the disperancy is 0.15 oz. Thus the value of the lower limit will be,
[tex]L=16-0.15\\L=15.85\rm \; oz[/tex]
The value of the upper limit will be,
[tex]U=16+0.15\\U=16.15\rm \; oz[/tex]
Thus, the range will be {15.85-16.15 oz}
Hence, the range of acceptable values for production to continue working of the company without stoppage is 15.85 to 16.15.

We are given with a function y and need to find dy/dx or the first Derivative of y w.r.t.x , but let's recall

A circular rug has a radius of 4. 5 feet. What is the circumference of the rug? Use 3. 14 for Pi and round to the hundredths place. 14. 13 28. 26 44. 37 88. 74.
Answer:
28.26
Step-by-step explanation:
The circumference of a circle is equal to 2πr, where r is the radius. The radius is the distance from the center of the circle to a point on the outside of the circle.
To find the circumference you can plug in the known information and multiply. However, instead of using actual pi, we will use 3.14 because that is what the question says.
2 * 3.14 * 4.5 = 28.26This means that the distance around the rug is 28.26 feet.

A delivery driver is driving around town and has noticed that every time he turns, it creates an angle. What are the measures of Angles X, Y, and Z on the map?
In your answer, give the measures of angles X, Y, and Z, and explain how you calculated each one.
Answer:
ok
Step-by-step explanation:
x:
X is adjacent to the 75 angle so x + 75 need to be 180.
180 - 75 = 105
x = 105
z:
Z is on opposite across outside corners from X so it will be the same thing.
z = 105
y:
Y is adjacent to Z so Y + Z must equal 180.
Z = 105
y + 105 = 180
y = 75

This is a trick question. They eat 1/3 of the gallons given. Multiply
1/3 * 1/3 = 1/9 gallons or 0.111 gallons
Answer: Aye aye, cap'in
Step-by-step explanation:
So we start off with our base value, 1/3 gallons.
We are trying to find how many gallons we have eaten, so we do 1/3*1/3, since we need to find what is 1/3rd of that gallon.
For reference, if you wanted to find how much is left over, we multiply by 2/3 since 1-1/3 = 2/3, so there are 2/3 of the 1/3rd gallons left. Not important for solving this problem, but it might help you understand why we decided to multiply by 1/3.
1/3 * 1/3 = 1/9
Our answer is 1/9.

Step-by-step explanation:
Diameter to Radius: [tex]\frac{1}{2}d = r[/tex]
Area of Circle: [tex]\pi r^2[/tex]
We are given the diameter of a pancake as 4.6 inches, so the radius is 2.3 inches. Next, we have to apply the area of circle formula with pi as 3.14 and the radius as 2.3
[tex]3.14 * 2.3^2[/tex] [tex]3.14 * 5.29[/tex] [tex]16.6106[/tex]Next, since there's two pancakes, we double 16.6106.

Answer:
y = 2, 5, 8, 11, 14
Step-by-step explanation:
For this question, it's simply asking us to solve for y, at given values of x. So everytime we just need to substitute the given value for x and solve for y.
x + y = 8
When x = 6,
6 + y = 8
substract 6 from both sides:
-6 + 6 + y = 8 - 6
y = 2
When x = 3
3 + y = 8
y = 8 - 3
y = 5
When x = 0
0 + y = 8 --> 0 + y = y
y = 8
When x = - 3
- 3 + y = 8
y = 8 + 3
y = 11
When x = - 6
-6 + y = 8
y = 8 + 6
y = 14
