a vendor bought n dozen eggs at the rate of 22.6 of the rotating he sold the remaining acts at the rate of 2.50 per act find his profit or loss
Answer:
Your question was a bit confusing so I found another related question. You can reference it with your own details.
A vendor bought 10 dozen eggs at the rate of Rs 22 per dozen. Six of the eggs were rotten. He sold the remaining eggs at the rate of Rs 2.50 per egg . Find his profit or loss
Vendor bought 10 dozen eggs which means the vendor bought:
= 10 * 12 eggs
= 120 eggs
6 were rotten and he sold the rest for Rs. 2.50 per egg.
= (120 - 6) * 2.5
= Rs. 285
The amount he spent on the eggs was:
= 10 dozen * 22
= Rs. 220
Profit = 285 - 220
= Rs. 65

Step-by-step explanation:
How does saving money in an account with compound interest help protect you from inflation?
Answer:
Inflation is caused by the increase in prices of goods, and as prices of goods rise, the value of money itself would decrease. By saving money in a savings account with interest that might be equal or more than the level of inflation, your money would increase, which protects you from the devaluation of the savings you hold and the rising prices of goods.
4/3C, when C=6
show your work here
4 divided by 3C
If C equals 6, then the equation now looks like 4 divided by 3(6).
3 x 6 = 18.
4 divided by 18 is .22 repeating.
This may be wrong. Check with another answer.
Answer: 2/9
Work: So, you are going to get the equation after plugging in the number 4/3(6), after simplifying even more, you get 4/18. Then you simplify again and divide both sides (Numerator and denominator) and you get 2/9.

Answer:

Step-by-step explanation:
A survey of over 7,000 randomly selected employees in 15 nations recently showed that employees who work
in a digital workplace tended to be happier than those who don't work in a digital workplace.
Can we conclude that working in a digital workplace caused employees to be happier? Why?
Answer:
Not necessarily, because this wasn't an experiment.
Step-by-step explanation:
Making conclusion based on the result of the survey about the happiness of employees due to the fact that they work in a digital workplace is inaccurate.
Statistical tests may not be enough to make generalization about the entire population due to the presence of a possible confounding or third variable unless established using scientific evidence.
Therefore, the lack of scientific evidence means that concluding that working in a digital workplace causes employee happiness is inaccurate.

50!!!!! Points If Jess wants to graph the solution to the system of equations below,
which of the following graphs would represent the solution?
ſ3x - y = -1
(x+y - 5
The graph that represents the solutions to the system of equations is Option A.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
3x - y = -1 _____(1)
x + y = 5 ______(2)
From (1),
3x + 1 = y
From (2),
y = 5 - x
The point of intersection is (1, 4).
3x + 1 = 5 - x
4x = 4
x = 1
Putting x = 1 in (2).
1 + y = 5
y = 5 - 1
y = 4
The graph on option A has the point of intersection at (1, 4).
Thus,
The graph that represents the solutions to the system of equations is Option A.

evaluate each expression |-16| -|-1|
Understanding the Absolute Value.
First, know what the absolute value is.
The absolute value is the value that determines how far the value is from 0.
For example, The absolute value of -5 is far from 0 5 units. Therefore the absolute value of -5 equals 5.
Basic Absolute Value Defines
| a | = a
- | a | = -a
| - a | = a
Back to the question. To evaluate those expressions, we use the defines of absolute value.
|-16| = 16
|-1| = 1
16-(1)
Then remove the brackets. 16 - 1 = 15
Therefore, the answer is 15.
The answer above is when being subtracted and evaluated from both 16-1
Evaluating for each expressions would be

A piecewise function is represented by the graph below.
On a coordinate plane, a piecewise function has 2 lines. The first line is made up of 2 lines. One line goes from (negative 5, 3) to (negative 1, negative 1) and then goes up to a closed circle at (1, 1). The second line has an open circle at (1, 2) and then continues up through (3, 4).
What is the domain for the piece of the function represented by f(x) = x + 1?

Answer:
x > 1
Step-by-step explanation:
The open dot at (1, 2) tells you that point is not in the domain. Apparently, the piece represented by f(x) = x+1 extends to +∞ from x = 1.
the domain of the piece is x > 1

The length of a rectangle plus its width is 32
cm. The area is 112 square cm. What are the
length and width of the rectangle?
Separate the answers with a comma.
Answer:
l = 28 cm and b = 4 cm
Step-by-step explanation:
Let the length be l and the breadth be b.
ATQ,
l+b = 32
l=32-b ....(1)
Area of rectangle, A = 112 cm²
We need to find the length and width of the rectangle
The formula for the area of a rectangle is given by :
lb = 112 ...(2)
From equation (1) and (2).
(32-b)b = 112
From above equation, b = 4 cm
Put the value of b in equation (1)
l=32-4
= 28 cm
Hence, the length and width of the rectangle is 28 cm and 4 cm.
The departure from the average is the difference between the actual amount of rain and the average amount of rain for a given month.
The historical average for rainfall in Albuquerque, NM for June, July, and August is shown in the table.
June 0.67 inches
July 1.5 inches
August 1.57 inches
Last June only 0.17 inches of rain fell all month. What is the difference between the average rainfall and the actual rainfall for last June? Answer with decimals.
The departure from the average rainfall last July was -0.36 inches. How much rain fell last July? Answer with decimals.
How much rain would have to fall in August so that the total amount of rain equals the average rainfall for these three months? Answer with decimals.
What would the departure from the average be in August in that situation? Answer with decimals.
The actual rainfall for last June is 0.5
1.14 is the amount of rain that fell last July.
2.43 is how much rain would have to fall for August to match the three months average
0.86 is the departure from the average in August
Step-by-step explanation:
1. 0.67-0.17 = 0.5
2. 1.5-0.36 = 1.14
Step-by-step explanation:
a) 0.5 inches. The difference between the average rainfall and the actual rainfall for last June is 0.67-0.17=0.50 inches.
b) 1.14 inches. Because the departure from the average was negative, the actual rainfall was 0.36 inches less than the average rainfall. Thus, 1.5-0.36=1.14 inches was the actual rainfall last July.
c) 2.43 inches. The average rainfall for these three months is 0.67+1.5+1.57=3.74 inches. Last June it rained 0.17 inches and last July it rained 1.14 inches. So, it would need to have rained 3.74-0.17-1.14=2.43 inches last August so that the total amount of rain equaled the average rainfall for these three months.
0.86 inches. The departure from the average would then be 0.86 inches since 2.43-1.57=0.86 inches.
