Amy is having her birthday party at a skating rink. The rink charges $50 plus $8 per person. If Amy wants to spend at most $200, how many people can she invite? (Hint: make sure you include Amy in the head count.)
Answer:
18
Step-by-step explanation:
Amy can invite 18 people (including herself). $200-$50=$150. $150÷8=18.75. You can't have 18.75 people so you round it down to 18. Hope this helps!
Answer: 18 people including herself
Step-by-step explanation: Take $200-$50=$150
now divide 150 by 8 which is 18.75 you obviously can't round up so you round down to just 18 and thats your answer. she can have 18 people there including herself
Simplify the expression below. Then write a different expression equivalent to the simplified expression: 4y² + 6x - 2y² + 12x
A. 4y² - 2y²
B. 2y² + 18x
C. 4y² + 6x - 2y² + 12x
D. 6x + 12x
Answer:
B or 2y² + 18x
Step-by-step explanation:
4y² + 6x - 2y² + 12x
combine like terms together:
4y² + (-2y²) = 2y²
6x + 12x = 18x
2y² + 18x = B

9. Consider the diagram below. First, solve for x, then y.
Answer:
x = 59
y = 32
Step-by-step explanation:
x + 78 + 43 = 180
x = 59
y + 59 + 89 = 180
y = 32
Answer:
y = 32; x = 59
Step-by-step explanation:
On the top triangle x+y+89=180 because a triangle's angles add up to 180 degrees, while a quadrilateral's angles add up to 360 degrees.
Angle 89 and the angle below it are supplementary, meaning together they equal 180 degrees.
180 - 89 = 91
So the angle below 89 is 81 degrees.
Now we can subtract the other three angles in the quadrilateral to find the fourth:
360 - (78 + 43 + 91) = 148
So the angle below y is 148 degrees.
Angle y and the angle below it are supplementary, meaning together they equal 180 degrees.
y = 180 - 148
y = 32
All of the angles in a triangle equal 180 degrees:
x = 180 - (32 + 89)
x = 59

The following data shows the weight, in pounds, of 6 bags:
6, 4, 8, 7, 8, 9
What is the value of the mean absolute deviation of the weight of the bags, and what does it represent about the weight of a bag?
A) 1.8 pounds; on average, weight of a bag varies 1.8 pounds from the mean of 7 pounds
B) 1.3 pounds; on average, weight of a bag varies 1.3 pounds from the mean of 7 pounds
C) 1.3 pounds; the weight of 50% of the bags is greater than 1.3 pounds
D) 1.8 pounds; the weight of 50% of the bags is greater than 1.8 pounds
Answer:
B
Step-by-step explanation:
Take all of the numbers and add them up and then divide by the number of numbers (In this case 6). This is the average which is 7. Then see how far each number is from 7 and take the average of those. This gives you 1.3. So, the answer is B.

A survey of a group of seventh-graders and a group of teachers at a local middle school asked how many siblings they each have. The dot plots below show the results.
Students
A dot plot titled Students. A number line going from 0 to 9 labeled the number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9.
Teachers
A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9.
Based on the shape of the two-dot plots, which statements correctly compare them? Select three choices.
The center of the data for students has a value less than that of the center of the data for teachers.
The center of the data is to the right of the dot plot for both teachers and students.
There is a greater variation in the data for teachers than for students.
Both sets of data cluster around 2.

Answer:
7. adjacent
8.127°
Step-by-step explanation:
adjacent angles on a straight line add up to 180°
180-53=127°
Answer:
they are supplementary
x = 127
Step-by-step explanation:
supplementary angles equal 180 degrees so you would do: 180 - 53 to find x

Answer: SU, TU, ST is the right answer
Step-by-step explanation: In a triangle
The largest side and the largest angle are opposite to each other
The shortest side and the shortest angle are opposite to each other.
So using the above axioms we can observe the triangle.
The largest angle is m∠U = 80° so the side opposite to it is the largest i.e. ST is the largest
The smallest angle is m∠T = 25° so the shortest side is SU
The third side will be the middle side as the angle ∠S is greater than 25° and less than 80°
So the sides in order from least to greatest are: SU, TU, ST
Mr. Burns built a wooden platform for the Drama Club at the school where he teaches. The shape below represents the dimensions of this wooden platform. (picture is not to scale) What is the surface area, in square feet, of this wooden platform?
Answer:
108 square feet
Step-by-step explanation:
First you want to break up the "L" into two parts. These parts can be seens as a and b. You need to find out the length on the left hand side, and half of it is 6ft as seen, so if half of it is 6ft, then you need to find the other half, which is obviously 6ft. 6+6=12, and to find the area of the thinner rectangle, multiply 2*24=48. That would be the area of section a. Section b is the bottom section and what you want to do is multiply 10*6 because this is how you would find the area of section b, which would be 60. 60+48=108. I know I was not very descriptive but I still hope this somewhat helps. I also might be wrong because of the fact that it says surface area despite the fact that this shape is 2D.
The surface area, in square feet, of this wooden platform is 84 ft².
What is Surface Area?The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.
We have L figured shape which can break as two rectangle.
So, the Area of rectangle 1:
= l w
= 6 x 2
= 12 square feet
and, Area of rectangle 2:
= l w
= 12 x6
= 72 square feet
Thus, the surface area of figure
= 12 + 72
= 84 square feet
