The number of tickets sold to adults is 274 and of tickets sold to students is 137.
What is the system of equations?A system of equations is a set of one or more equations involving a number of variables.
Let the number of tickets sold to adults be x.
And the number of tickets sold to students be y.
A total of 411 tickets were sold for the school play.
x + y = 411
The number of student tickets sold was two times the number of adult tickets sold.
x = 2y
Substitute the value of x in equation 1
[tex]\rm x + y = 411\\\\2y+y=411\\\\3y=411\\\\y =\dfrac{411}{3}\\\\y= 137[/tex]
Substitute the value of y in equation 2
[tex]\rm x = 2y\\\\x= 2\times 137 \\\\x =274[/tex]
Hence, the number of tickets sold to adults is 274 and of tickets sold to students is 137.

In the diagram, m∠COE = 55°. If m∠2 = 2x and m∠3 = x+10, what is the measure of angle 2?
15
30
45
60
Answer:
The answer is 30
Step-by-step explanation
You gather what you knowCOE = 55°, m∠2 = 2x, m∠3 = x + 10
Then you set up an equation using that information2x + x + 10 = 55
Combine like terms3x + 10 = 55
Find xX= 15
Plug in "x = 15" to "2x" to find out what the measure of angle 2 is2 x 15 = 30
Therefore m∠2 = 30

Working alone, it would take Shandra 45 minutes to mow the lawn. To mow the same lawn, also working alone, it would take Kelly 1 hour and 15 minutes. If they work together, the girls believe it will take them 1 hour to mow the lawn.
Which best describes the reasonableness of their solution? Their estimate is longer than the time it will actually take: Their estimate is accurate: Their estimate is shorter than the amount of time it will actually take: Their estimate is longer than the time it will actually take:
The correct answer is:
Their estimate is longer than the time it will actually take.
( Since, Estimated time-- 1 hour=60 minutes
Time actually taken= 28.125 minutes )
Step-by-step explanation:Time taken by Shandra alone to mow the field is: 45 minutes.
Time taken by Kelly alone to mow the field is: 1 hour 15 minutes.
We know that:
1 hour=60 minutes
Hence, 1 hour 15 minutes=60 minutes +15 minutes=75 minutes.
By looking at the time we consider that the total work be of 225 units.
This means that the Efficiency of Shandra is: 225/45=5 units/minutes.
Similarly,
Efficiency of Kelly is: 225/75=3 units/minutes.
Now, when they will work together there efficiency will be added.Hence, 5+3=8
Hence, the time taken by both of them when they work together is:
225/8
= 28.125 minutes.
But it was estimated that they took 1 hour=60 minutes.
Hence, there estimation of time taken was longer than what they actually took.

When granular materials are allowed to fall freely, they form conical (cone-shaped) piles. The naturally occurring angle of slope, measured from the horizontal, at which the loose material comes to rest is called the angle of repose and varies for different materials. The angle of repose θ is related to the height h and base radius r of the conical pile by the equation θ = cot-1(r/h). A certain granular material forms a cone-shaped pile with a height of 19 feet and a base diameter of 30 feet. What is the height of a pile that has a base diameter of 104 feet?
The angle of repose is calculated using the equation θ = cot-1(r/h). For a pile with a height of 19 feet and a base diameter of 30 feet, the angle of repose is approximately 38.03 degrees. Using this angle and the base diameter of 104 feet, we can find that the height of the new pile is approximately 77.07 feet.
The angle of repose θ is related to the height h and base radius r of the conical pile by the equation θ = cot-1(r/h).
Given a pile with a height of 19 feet and a base diameter of 30 feet, we can find its base radius by dividing the diameter by 2, which gives us a radius of 15 feet.
Now, we can substitute the given values into the equation to find the angle of repose θ.
θ = cot-1(15/19)
Using a calculator, we find that the angle of repose is approximately 38.03 degrees.
Next, we can use the height of the new pile and the known angle of repose to find its base radius.
Given a base diameter of 104 feet, the radius is half of the diameter, so the radius is 52 feet.
Now, we can use the equation θ = cot-1(r/h) and solve for h to find the height of the new pile.
h = r / tan(θ)
Substituting the known values, we get:
h = 52 / tan(38.03)
Using a calculator, we find that the height of the pile with a base diameter of 104 feet is approximately 77.07 feet.

A cannery processed 1,445 pounds of strawberries in 4.5 hours. The cannery processed 2,320 of strawberries in 7 hours. Write a linear equation to model the relationship between the weight of strawberries S and time T. How many pounds of strawberries can be processed in 11 hours?
The linear equation to model the relationship between the weight of strawberries and time can be found using the slope and y-intercept. The equation is S = 690T - 560.5. In 11 hours, the cannery can process 7109.5 pounds of strawberries.
Explanation:To write a linear equation to model the relationship between the weight of strawberries S and time T, we need to determine the slope and the y-intercept. The slope represents the rate at which strawberries are processed per hour, while the y-intercept represents the initial amount of strawberries processed.
Using the given information, we can use the formula for calculating the slope (m) of a line: m = (y2 - y1) / (x2 - x1). Plugging in the values, we have: m = (2320 - 1445) / (7 - 4.5) = 690 pounds/hour.
Next, we can calculate the y-intercept (b) using the formula: b = y - mx. Plugging in the values for one of the points (1445 pounds in 4.5 hours), we have: 1445 = 690(4.5) + b. Solving for b, we get: b = -560.5 pounds.
Therefore, the linear equation to model the relationship between the weight of strawberries S and time T is: S = 690T - 560.5. To find the number of pounds of strawberries that can be processed in 11 hours, we can substitute T = 11 into the equation: S = 690(11) - 560.5 = 7109.5 pounds.

Amanda has a job transporting soft drinks by truck. Her truck is filled with cans that weigh 14 ounces each and bottles that weigh 70 ounces each. There is a combined total of 930 cans and bottles in her truck. Let x be the number of 14 -ounce cans in her truck. Write an expression for the combined total weight (in ounces) of the cans and bottles in her truck.
The combined total weight of the cans and bottles in the truck, if x represents the number of 14-ounce cans, can be represented by the expression 14x + 70(930 - x). This combines the weight of the 14-ounce cans (14x) with the weight of the 70-ounce bottles (70(930-x)).
Explanation:In order to find the expression for the combined total weight (in ounces) of the cans and bottles in the truck, we have to first determine the number of bottles. We know that the total number of cans and bottles is 930, so the number of bottles would be 930 - x. Each can weighs 14 ounces and each bottle weighs 70 ounces. Therefore, the total weight in ounces will be the sum of the weight of cans and the weight of bottles. This can be represented as 14x + 70(930 - x). This expression represents the combined total weight in ounces of the items in Amanda's truck.

In the normal distribution, values in the distribution being measured are close to the mean (high or low values are infrequently found). true or false ?
Answer: True.
Step-by-step explanation:
Hi, the statement "In the normal distribution, values in the distribution being measured are close to the mean (high or low values are infrequently found)." is true.
The normal distribution is a probability function that how the values of a measure are distributed. Most of the values cluster around the mean, it’s a symmetric distribution.
Normal or Gaussian distributions Means that many variables have similar characteristics. So, middle values have higher probability or are more likely to occur, and extremely low or high values are more infrequent.
