the answer is 7.4
To find the mean, you add all of the numbers together and divide by the amount of numbers added.
1. 2. 3. 4.
ex: 3+6+7+10=26. there are four numbers before the equal sign.
So the mean is 26÷4 or 6.5
since there are 5 total numbers, and all of the numbers added equal 37, then divide by 5, which will equal 7.4

HELP The county fair charges $10 admission and $2 per ride. What is the cost for one admission and r rides
Answers
The cost for one admission is $10, and the cost for one ride is $2.
To find the cost for r rides, we need to multiply the cost per ride by the number of rides, which gives:
cost for r rides = $2 x r = $2r
To find the total cost for one admission and r rides, we need to add the cost of one admission and the cost for r rides, which gives:
total cost = cost for one admission + cost for r rides
total cost = $10 + $2r
total cost = $2r + $10
Therefore, the cost for one admission and r rides is $2r + $10.
Answer:
To solve this question, we need to multiply the per-ride cost, which is $2, by the number of rides, r. Then, we need to add the cost of admission, which is $10, to the cost of the rides.
The equation for the cost of one admission and r rides is:
Cost = $10 (admission) + $2r (rides)
So, to find the cost for one admission and r rides, we need to plug in the value for r. For example, if r = 2, the cost would be:
Cost = $10 (admission) + $2(2) (rides) = $14
So, the cost for one admission and 2 rides would be $14.
Similarly, if r = 4, the cost would be:
Cost = $10 (admission) + $2(4) (rides) = $22
So, the cost for one admission and 4 rides would be $22.
explain how you find the Area of a Circle
Answers
Answer:
A=πr2
Step-by-step explanation:
That is the formula to solve areal for a circle.
Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula ( = π ² ) , (Pi r-squared) where is the radius of the circle. The unit of area is the square unit, such as m2, cm2, etc.
is the region covered or enclosed within its boundary. It is measured in square units. Any geometrical shape has its own area. This area is the region that occupies the shape in a two-dimensional plane. So the area covered by one complete cycle of the radius of the circle on a two-dimensional plane is the area of that circle.
As we know, the is equal to of its radius, i.e. π . To find the area of circle we have to know the of the circle.
For example, if the radius of circle is 7cm, then its area will be:
Area of circle with 7 cm radius = πr2 = π(7)2 = 22/7 x 7 x 7 = 22 x 7 = 154 sq.cm.

Ross drives 340 miles in 5 hours. If Ross continues to drive at the same rate, how many miles can he drive in 10 hours?
Answers
Answer:
Including the miles already driven: 680
Step-by-step explanation:
1. We can see that 5 is half of 10, or 1/2.
2. Times 340 by 2 because he has has already driven 1/2 of the time needed, so he needs to drive another 5 hours in order to complete the 10 hours needed.
Or: 340 x 2 = 680.
3. So in 10 hours he will have driven 680 miles.

1.) Seven more than a number is less than 18. Find the number.
2.) Five more than a number is greater than 26. Find the number.
3.) The sum of two consecutive integers is less than 55. Find the pair of integers with the greatest sum.
4.) The length of a rectangle is 4cm longer than the width. The perimeter is no more than 28cm. What are the maximum possible dimensions for the rectangle?
5.) The sum of three consecutive odd integers is no less than 51. What is the middle integer?
Answers
Answer:
1.) Let x be the number. The inequality can be written as:
x + 7 < 18
Subtracting 7 from both sides, we get:
x < 11
Therefore, the number is less than 11.
2.) Let x be the number. The inequality can be written as:
x + 5 > 26
Subtracting 5 from both sides, we get:
x > 21
Therefore, the number is greater than 21.
3.) Let x be the first integer. The second integer is x+1. The inequality can be written as:
x + (x+1) < 55
Simplifying, we get:
2x + 1 < 55
Subtracting 1 from both sides, we get:
2x < 54
Dividing both sides by 2, we get:
x < 27
Therefore, the largest possible first integer is 26, and the second integer is 27. Their sum is 53.
4.) Let w be the width of the rectangle. The length is 4cm longer than the width, so the length is w + 4. The perimeter is given by:
2(length + width) ≤ 28
Substituting the expressions for length and width, we get:
2(w + 4 + w) ≤ 28
Simplifying, we get:
4w + 8 ≤ 28
Subtracting 8 from both sides, we get:
4w ≤ 20
Dividing both sides by 4, we get:
w ≤ 5
Therefore, the maximum possible width is 5cm, and the maximum possible length is 9cm.
5.) Let x be the first odd integer. The second and third odd integers are x+2 and x+4, respectively. The inequality can be written as:
x + (x+2) + (x+4) ≥ 51
Simplifying, we get:
3x + 6 ≥ 51
Subtracting 6 from both sides, we get:
3x ≥ 45
Dividing both sides by 3, we get:
x ≥ 15
Therefore, the smallest possible first odd integer is 15, and the second and third odd integers are 17 and 19, respectively. The middle integer is 17.

Which of the following explains the student's error?
Multiple choice questions.
cross out
A)
The two angles must equal 90°, so 2x+6+60=90
C)
The two angles do not equal 180°. They are vertical angles, so 2x+6=60
D)
The student should have added 66 to both sides of the equation instead of subtracting 66.
Part B
Fill in the blank question.
What is the correct solution?
Answers
The correct explanation for the student's error is: (C) The two angles do not equal 180°. They are vertical angles, so 2x+6=60
Vertical angles are pairs of angles formed when two lines intersect. These angles are opposite each other and have equal measures. However, the student incorrectly assumed that the vertical angles were supplementary angles (adding up to 180°).
As a result, they set up the equation as 2x + 6 + 60 = 180, which does not apply to vertical angles. This is why option C explains the error by stating that the two angles are vertical angles, and the correct equation should be 2x + 6 = 60.
To solve the correct equation for 'x', which is 2x + 6 = 60, follow these steps:
Start with the equation: 2x + 6 = 60Subtract six from both sides of the equation: 2x = 54Divide both sides by 2: x = 27The correct solution is x = 27, which means that the value of 'x' that satisfies the equation 2x + 6 = 60 is 27. This correctly reflects the measure of the angle within the given context.
In summary, the student's error stemmed from misunderstanding the nature of vertical angles and incorrectly assuming that they were supplementary angles. By recognizing the correct characteristics of vertical angles and applying the appropriate equation, the solution can be accurately determined as x = 27.

Using the second highlight above, we have:
This means that, the special angles created are:
Vertically opposite angles
Adjacent angles
Value of y, and the measures of <7 and <8
We have:
--- vertically opposite angles
Collect like terms!
Divide both sides by 2

Bob ust choose a shirt and a pair of pants for today's outfit. He has 2 shirts and 3 pairs of pants to choose from how many different outfits can he make.
Answers
Answer:
6 outfits.
Step-by-step explanation:
Bob has 2 shirts and 3 pairs of pants. That means he can wear one of the two shirts with any of the three pants (which'd make 3 outfits) and then with the other shirt with any of those three pants again (which'd make another three outfits.
Since you want to find out how many outfits Bob can make using the five articles of clothing, therefore 3+3=6 and 6 outfits would be your answer.
If you want to think of this problem another way, in simpler terms you can think of it like this: 2*3=6. Two shirts times three pants, which equals to six that makes our answer Bob can make six different outfits from his options above.

Deena works at a customer service call center. She fields an average of 6 calls per hour. Employees are encouraged to field more than 240 calls per week. Deena has already fielded 120 calls this week. How many more hours,x , does Deena need to work this week to reach the weekly goal of fielded calls?
A. x>20
B. x>40
C. x>26
D. x>2
Answers
Step-by-step explanation:
Deena's goal is to take 200 calls this week.
She already answered 85 calls this week, so she's missing 115 (200-85) calls for her goal.
She takes about 5 calls per hour, so how many hours does she need to work more?
h = 115 calls / (5 calls/h) = 23 hours
So, she needs to work at least 23 more hours... so x > 23.
Koharu bought a bag of fruits.
The total weight of the fruits was `1` pound.
What could she have bought?
Answers
Koharu could have bought a variety of fruits that add up to 1 pound in weight. Some examples of fruits and their approximate weights per piece are:
- Apples: 1 large apple = 0.5 pounds
- Bananas: 1 medium banana = 0.3 pounds
- Oranges: 1 medium orange = 0.3 pounds
- Grapes: 1 cup of grapes = 0.5 pounds
- Strawberries: 1 cup of strawberries = 0.3 pounds
- Blueberries: 1 cup of blueberries = 0.3 pounds
So Koharu could have bought a combination of these fruits that adds up to 1 pound in weight. For example, she could have bought 2 large apples (1 pound), or 3 medium bananas and 2 medium oranges (1.2 pounds), or 2 cups of grapes and 1 cup of blueberries (1.3 pounds), and so on.
