Find the area of the circle. Round your answer to two decimal places, if necessary.
Answers
200.96 cm
Step-by-step explanation:Area of a circle: [tex]A=[/tex] [tex]\pi r^2[/tex]Since we don't have the radius, we have to find it.
What you gave me is the diameter which is 16 (cm) I suppose.
Radius is half the diameter. Therefore we can divide the diameter by 2 to find the radius.
[tex]16[/tex] ÷ [tex]2=8[/tex]
This is our radius.
Plug this into the area formula.
[tex]A=\pi r^2[/tex]
[tex]A=(3.14)(8)^2[/tex]
[tex]A=200.96cm[/tex]

Answer:
88cm2
Step-by-step explanation:
You need to first find the area of all sides except the bottom, as you can see the bottom is a rectangle which means the triangles across from each other will have the same measurements.
To find the area of a triangle the formula is 1/2ab
1/2*8*6= 24
1/2*8*5=20
20*2+24*2=88
Therefore the answer is 88 cm2
Write an expression that represents the difference of (4x + 2/3y) and (4/12y - 8.7x)
Help
Answers
Explanation:
(4x + 2/3y) - (4/12y - 8.7x) = 12.7x+1/3y
Convert 12.7x in the difference to a fraction, which is 127/10x.
Factor out 1/30 from 127/10x + 1/3y
Solution: 1/30x (381x+10y)
12.7x+1/3y
An elevator is being pulled up from the ground floor to the third floor by a cable. The cable is exerting 4500 newtons of force on the elevator. According to Newton's law of action-reaction, what is the gravitational force on the elevator and the people in it, in newtons, if the elevator is not accelerating?
Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answers
Answer:
The gravitational force on the elevator = 4500N
The given parameters are;
The force applied by the elevator, F = 4500 N
The acceleration of the elevator = Not accelerating
From Newton's third law of motion, the action of the cable force is equal to the reaction of the gravitational force on the elevator which is the weight, W and motion of the elevator as follows;
F = W + Mass of elevator × Acceleration of elevator
∴ F = W + Mass of elevator × 0 = W
F = 4500 N = W
The net force on the elevator is F - W = 0
The gravitational force on the elevator = W = 4500N.
Answer:
The gravitational force on the elevator = 4500N
The given parameters are;
The force applied by the elevator, F = 4500 N
The acceleration of the elevator = Not accelerating
From Newton's third law of motion, the action of the cable force is equal to the reaction of the gravitational force on the elevator which is the weight, W and motion of the elevator as follows;
F = W + Mass of elevator × Acceleration of elevator
∴ F = W + Mass of elevator × 0 = W
F = 4500 N = W
The net force on the elevator is F - W = 0
The gravitational force on the elevator = W = 4500N.

Jacob says that 1 1/8 inches is an outlier because it is the only length that does not have any dots. Is Jacob correct? Explain.
A. Jacob is correct. All of the other data values have dots, so a data value without dots is different and is therefore an outlier.
B. Jacob is not correct. An outlier is a data value that is very different than the other data values that have at least 1 dot.
C. Jacob is not correct. An outlier can lie anywhere on the line plot, and it must have exactly 1 dot.
D. Jacob is not correct. The outlier is 1 4/8 inches because the outlier is always the greatest data value.
Answers
A.Jacob is correct. The correct value is 1 1/8 inches. All of the other data values have dots, so a data value without dots is different and is therefore an outlier.
What is an Outlier?An outlier is an observation that lies at an abnormal distance from other values in a random sample from an Experiment.
On observing the given figure length that does not have any dots is between
[tex]1 \ and\ 1\dfrac{2}{8}[/tex]
Calculatte the value between it
[tex]\dfrac{1+1\dfrac{2}{8}}{2}\\=\dfrac{\dfrac{18}{8}}{2}\\\\=\dfrac{9}{2}\\\\=1\dfrac{1}{8}[/tex]
Hence Jacob is correct. All of the other data values have dots, so a data value without dots is different and is therefore an outlier.

Maria has the following scores on exams in her social studies class: 86, 75, 97, 58, 94, and 58.
A. Find the mean, median, and mode of the scores.
B. Should Maria’s social studies teacher use the mean, median, or mode of the exam scores to convince Maria that she needs to study more regularly for her exams?
Answers
Answer:
Below in bold.
Step-by-step explanation:
Arrange the scores in ascending order:
58 58 75 86 94 97
A. The mean = (58+58 +75+ 86+ 94+ 97)/6
= 468/6
= 78.
The median = (75+ 86)/2 = 80.5.
The mode = 58.
B. She should use the mode as it is the lowest score.
Explanation: the mean is the average number in a data set, meaning you have to add all of the numbers and divide by the number of values (86 + 75 + 97 + 58 + 94 + 58) / 6
Median: 80.5
Explanation: The median is the value that separates the higher half from the lower half in a data set. in this case, you have to order the numbers least to greatest and since there is an even amount of numbers, you take the two middle ones and find the average of the two. (75 + 86) / 2
Mode: 58
Explanation: the mode is the value that appears most frequently in a data set, in this case it is 58
Part B: Maria’s social studies teacher should use the mode of the exam scores to convince Maria that she needs to study my regularly for her exams because it is the lowest score
