Sarah ordered 38 shirts that cost $7 each. She can sell each shirt for $16. She sold 31 shirts to customers. She had to return 7 shirts and pay a $2 charge for each returned shirt. Find Sarah's profit.
I didn't get this, please help me out.
Answers
Answer:
Profit = $216
Step-by-step explanation:
To solve this, let's first calculate the amount she spent buying 38 shirts at $7 each:
• total spent = 38 × 7
= $266
We are told that she then sold 31 shirts at $16 each. Using this information, let us now calculate the total amount she earnt selling these shirts:
• total earnt = 31 × 16
= $496
Next, she returned 7 shirts and paid a $2 charge for each returned shirt. Therefore, the amount she spent on returning was:
• total spent returning = 7 × 2
= $14
Therefore she earned a total of $496 and spent $266 and then $14. We can calculate her profit by subtracting the two expenditures from the earnings:
• Profit = $496 - $266 - $14
= $216
Hence her profit was $216.
In this problem, you will investigate the relationships among three points of concurrency in a triangle.

Answers
Construct an acute triangle and find the centroid (medians), circumcenter (perpendicular bisectors), and orthocenter (altitudes). Take note of how these three centers interact with one another from the figure.
What are acute triangles?
An acute angle triangle (also known as an acute-angled triangle) is a triangle with all of its interior angles being acute angles. Remember that an acute angle is one that is less than 90°.
A triangle with three acute angles is known as an acute triangle. An obtuse triangle has one obtuse angle and two acute angles. Because the angles of a triangle in Euclidean geometry must sum to 180°, no Euclidean triangle can have more than one obtuse angle.

The perimeter of a square is 4 times as
great as the length of any of its sides.
Determine if the perimeter of a square is proportional to its side length. Explain.
Answers
Answer:
Perimeter of a square is proportional to side length
Step-by-step explanation:
We have the relation p = 4a, p = perimeter, a = side length
This is the equation for a proportionate relationship of the form y = k.x where y ∝ x , y directly proportional to x => y varies as x varies and always by the same constant
k is known as constant of proportionality
Here k = 4
Let's say the side of square is 1. Then perimeter = 4
If side is increased to 2, then perimeter = 4 x 2 = 8
If side is increased to 3, then perimeter is 4 x 3 = 12
So perimeter increases by a factor of 4 for every unit increase in side length

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100.One percent is one hundredth of a whole. It can therefore be written as both a decimal and a fraction. To write a percentage as a decimal, simply divide it by 100. For example, 50% becomes 0.5, 20% becomes 0.2, 1% becomes 0.01 and so on.Percentages are used widely and in many different areas.

Probability for 1st successful serve is 0.4.Probability for 2nd successful serve is 0.42.Probability for no successful serve is 0.18.What is termed as probability?Probability is a mathematical concept concerned with determining the likelihood of occurrence of a given event, which is demonstrated as a range of 1 and 0. A certainty is an event with such a probability of one.
Now, as per the given question;
Kelly's first serve percentage is 40% = 0.4.
Kelly's second serve percentage is 70% which comprises of successful and faulty serve.
The probability that the second serve will be successful is;
