What is the value of x and y?
Answer: y=41 and x=41
Answer:
x=41 y=41
Step-by-step explanation:
y is a mirror of the other side which is 41 degrees. So y=41. m and n are parallel so x is also equal to 41.

There is a linear relationship between the number of roses blooming in the garden and the number of days that pass. After 4 days, there are 22 rose blooms left, and after 8 days, there are 10 rose blooms left.
Which of the following graphs represents the relationship?
Answer:
The first graph is correct.
Step-by-step explanation:
After 4 days, there are 22 rose blooms left -------(4, 22)
and after 8 days, there are 10 rose blooms left -----(8 , 10)
Equation of straight line:
y =ax +b
input (4, 22) and (8, 10)
22 = 4a + b ----(1)
10 = 8a +b ------(2)
solve to find a , b
(2) - (1)
-12 = 4a, a= -3
find b, b = 34
Equation is : y= -3x + 34
When you set x = 0, y is 34.
The first graph is correct.

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.

Determine whether the sample may be biased. Explain.
Two hundred people at a town festival are randomly asked to compare energy bar A to energy bar B.
A or B?
Answer:
The sample may not be biased. The two hundred people at the town festival were randomly asked to compare energy bar A to energy bar B, which suggests that the sample was chosen in a way that attempts to represent the opinion of the entire population. Therefore, the results of the survey can be used to make a general statement about how people feel about the two energy bars.

The probability that a student studied for 5 hours is 0.23 Or 23%.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
A table is given where the first column represents the number of hours a student studied maths and the second column represents the number of students.
The sum of the second column is 30 so it is the total number of students
And only 7 of them studied mathematics for 5 hours.
Therefore, The probability that a student studied for 5 hours is,
= 7/30.
= 0.23 or 23%.

The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?
160 ml
400 ml
1,600 ml
4,000 ml
Answer: 1,600 ml
Step-by-step explanation:
You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).
2,800 ml - 1,200 ml = 1,600 ml
I hope this helps :)
Answer: 1,600 mL
Step-by-step explanation:
1. convert the 1,200 mL to L, which is 1.2 L.
2. Subtract that value from 2.8 L, equaling 1.6 L
3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.

A cone has a slant height of 15 cm and a height of 12 cm.
What is the radius of the cone?
cm.
What is the volume of the cone?
cubic centimeters.
Answer:
The answer to your question is 9 cm
Step-by-step explanation:
Data
slant height = 15 cm
height = 12 cm
radius = ?
Process
To solve this problem, use the Pythagorean theorem. The slant height is the hypotenuse, the height is the long leg and the radius is the short leg.
c² = a² + b²
slant height² = height² + radius²
-Solve for radius
radius² = slant height² - height²
-Substitution
radius² = 15² - 12²
-Simplification
radius² = 225 - 144
radius² = 81
-Result
radius = 9 cm

Mason opens a savings account by making a $165.85 deposit. Every week, he deposits another $20.50 in the account.
Write an expression that shows the amount of money that will be in the account x weeks after Mason opens it.
165.85x + 20.5
165.85 – 20.5x
165.85 + 20.5 + x
165.85 + 20.5x
165.85 is priliminary deposit i.e fixed and first deposit so it will become y intercept of our expression
20.5 is rate of change as he adds it once every week.

The drama club is selling tickets to their play to raise money for the show's expenses.
Each student ticket sells for $4.50 and each adult ticket sells for $8. The auditorium
can hold no more than 84 people. The drama club must make at least $560 from
ticket sales to cover the show's costs. If 29 student tickets were sold, determine all
possible values for the number of adult tickets that the drama club must sell in order
to meet the show's expenses. Your answer should be a comma separated list of values.
If there are no possible solutions, submit an empty answer.
Answer:
The minimum number of adult tickets required to be sold = 54
Step-by-step explanation:
Hello,
In this question, we have several variables which might confuse us here, so I'll have to break it down bit by bit.
The drama club must make a sale of $560 so as to cover cost for the event.
The seat capacity of the hall = 84
Cost of tickets for adult = $8
Cost of tickets for students = $4.50
Total number of students sold = 29
Let the number of adult ticket required = x.
(4.50 × 29) + (8 × x) = 560
130.5 + 8x = 560
8x = 560 - 130.5
8x = 429.5
Divide both sides by 8
X = 429.5 / 8
X = 53.6 approximately 54.
Minimum required number of adult tickets to be sold is 54.
(29 × 4.50) + (54 × 8) = $130.5 + $432 = $562.5
