A model plane has a scale of 1 in 6 yards if the model plane is 3 in tall then how tall is the real plane
The real plane is 18 yards tall if the model plane is 3 in tall.
What is Scaling ?
A physical model that is geometrically similar to an object is called a scale model (known as the prototype).
Scale models are typically more compact than huge prototypes like cars, structures, or people.
Divide the length by the conversion factor to convert a measurement in inches to a measurement in yards.
Since 36 inches are equivalent to one yard, you may convert using the following straightforward formula:
yards = inches/ 36
Given:
inches / yards =1:6
As we know the model of the plane is 3 inches tall.
Therefore, we can convert the 3 inches to x yards.
[tex]\frac{1inch}{6yards} =\frac{3inches}{x yards}[/tex]
1 /6= 3/x
By cross multiplying the above equation we can get the value of x.
1x= 6×3
x=18
x= 18 yards
The real plane is 18 yards.

What multiple of 81 is between 80200 and 80300?
Answer:
80 271
Step-by-step explanation:
80200 / 81 = 990.123
so 991 * 81 = 80 271
The multiple of 81 between 80200 and 80300 is 80271.
What is multiple?Multiple can be thought of as how many times a number is being multiplied, Like 81n where n ∈ N.
The difference between 80200 and 80300 is 100 and it is not twice the value of 81 so there will be only one such number which is a multiple of 81.
One easy way of determining it divide the larger value by 81 and subtract the remainder from it.
∴ 80300 ÷ 81.
= (991×81) + 29.
∴ The multiple of 81 between 80200 and 80300 is

a) A couple of entrepreneurial business students decided to put their education into practice by developing a tutoring company for business students. While private tutoring was offered, it was determined that group tutoring before tests in the large statistics classes would be most beneficial. The students rented a room next to campus for P3000.00 for 3 hours. They developed handouts based on past tests and these handouts (including colour graphs) cost P50 each. The tutor was paid P250 per hour for a total of P750 for each tutoring session.
i) If students are charged P200 to attend the session, how many students must enrol for the company to break evenA somewhat smaller room is available for P200 for 3 hrs. The company is considering this possibility. How would this affect the BEP?
According to the information, it can be inferred that in the room worth 3,000, the break-even point would be 25 students enrolled. On the other hand, in the room of 200, the break-even point would be 7 students enrolled.
What is the Break-even point?The break-even point is an economic term to refer to the moment when a company's income covers its fixed and variable expenses, that is, when you manage to sell the same amount you spend, you neither win nor lose, you have reached the break-even point.
Thus, calculating the break-even point is essential for companies to assess their profitability, since in this way it is possible to know how much they need to sell to generate profit. Knowing this value, even before starting a new project, allows you to know how financially interesting your business idea is.
How to clculate the break-even point in this case?To calculate the break-even point, we must take into account the expenses that the students will have to offer their service:
Room 1: 3,000Room 2: 200Tutor: 750According to the above, the expenses in case A, with room 1 would be:
3,000 + 750 = 3,750On the other hand, the expenses in case B with room 2 would be:
200 + 750 = 950So, we know that in case A the expenses are going to be 3,750 and in case B the expenses are going to be 950. To find the break-even point for each case, we must divide this value by the price at which they are going to sell the item. course to students. However, it should be clarified that it must be divided by 150 because 50 will be used to pay for each student's handouts.
3,750 ÷ 150 = 25
950 ÷ 150 = 6.33 = 7
According to the above, the break-even point for case A would be 25 students. Additionally, in case B the balance point would be 6.33 students who are close to 7.
To conclude, it can be stated that the best option would be to take room 2 because they will have fewer expenses and will have to sell fewer units of their course to reach the break-even point.

6. Sal is selling two types of printed socks. He sells type a at R45 a pair. He sells type b at R30. If he sold 16 pairs in total, and had a total income of R585, how many pairs of sock b did Sal sell?
Step-by-step explanation:
a + b = 16
a = 16 - b
45a + 30b = 585 | divide both sides by 15
3a + 2b = 39
now we are using the first in the second equation :
3(16 - b) + 2b = 39
48 - 3b + 2b = 39
48 - b = 39
48 = 39 + b
9 = b
he sold 9 pairs of type b socks.
FYI :
a = 16 - b = 16 - 9 = 7

What is Degree of Freedom?
The largest number of logically independent values—that is, values with the freedom to change—in the data sample is referred to as the degree of freedom. When calculating degrees of freedom, one is subtracted from the total number of items in the data sample.
The degrees of freedom are (r - 1)(c - 1) when evaluating the independence of characteristics in a contingency table with r rows and c columns.
Given, rows = 4
columns = 4
degree of freedom = (r - 1) (c - 1)

Step-by-step explanation:
Given the midpoint formula: ([tex]\frac{x_2+x_1}{2},\frac{y_2+y_1}{2}[/tex]),the Segment Addition Postulate, and the line attached, find x, HK, HJ, KJ
1st step is in the picture.
doing the first step gives us [tex]x + 9[/tex]
Since k is the midpoint, both sides of the midpoint are the same length
so we can use the equation [tex]3x - 10 = x+9[/tex]
subtract x from both sides: [tex]3x-10-x=x+9-x[/tex]
[tex]2x-10=9[/tex]
[tex]2x-10+10=9+10[/tex]
[tex]2x=19[/tex]
[tex]2x/2=19/2[/tex]
[tex]x=9.5[/tex]
Now that we know x, we can substitute to find HK, HJ, and KJ
[tex]HK = 3(9.5)-10[/tex]
[tex]HJ = 4(9.5)+19[/tex]
[tex]KJ = x +9[/tex]
