Which figure has exactly one line of symmetry? A rhombus, pentagon, rectangle and triangle are shown. A. Rhombus B. Pentagon C. Rectangle D. Triangle
Answer: The figure that has exactly one line of symmetry is B. Pentagon.
Step-by-step explanation: A line of symmetry is a line that divides a figure into two congruent halves that are mirror images of each other. A figure can have zero, one, or more lines of symmetry depending on its shape and orientation. To find the lines of symmetry of a figure, we can use a paper folding method or a reflection test. A paper folding method involves folding the figure along a line and checking if the two halves match up exactly. A reflection test involves reflecting the figure over a line and checking if the image coincides with the original figure.
Using either method, we can see that:
A. Rhombus has two lines of symmetry: one diagonal and one vertical.
C. Rectangle has two lines of symmetry: one horizontal and one vertical.
D. Triangle has either zero or three lines of symmetry depending on the type of triangle. An equilateral triangle has three lines of symmetry: one vertical and two bisecting the angles. An isosceles triangle has one line of symmetry: the perpendicular bisector of the base. A scalene triangle has no lines of symmetry.
B. Pentagon has either zero or five lines of symmetry depending on the type of pentagon. A regular pentagon has five lines of symmetry: each passing through a vertex and the midpoint of the opposite side. An irregular pentagon has no lines of symmetry.
Therefore, the only figure that has exactly one line of symmetry is B. Pentagon, but only if it is an isosceles pentagon.
Hope this helps, and have a great day! =)

A teacher was interested in the subject that students preferred in a particular school. He gathered data from a random sample of 100 students in the school and wanted to create an appropriate graphical representation for the data.
Which graphical representation would be best for his data?
Stem-and-leaf plot
Histogram
Circle graph
Box plot
The best graphical representation for the teacher's data on the subject preferences of 100 students in the school would be a circle graph, also known as a pie chart.
A circle graph is a circular chart that is divided into sectors, each representing a proportion of the whole. In this case, the "whole" would be the total number of students surveyed (100), and each sector would represent the proportion of students who preferred a particular subject.
Since the teacher is interested in the subject preferences of the students, a circle graph would be an ideal choice because it allows for a clear and easy-to-understand visual representation of the proportions of students who prefer each subject. The size of each sector would be proportional to the percentage of students who prefer that subject, making it easy to compare the preferences of different subjects.
Stem-and-leaf plots, histograms, and box plots are all useful graphical representations for different types of data, but they are not suitable for the categorical data (i.e., the subject preferences) that the teacher is interested in. Therefore, a circle graph would be the best choice for this particular data.

10 POINTS PLEASE HELP the arthemitic mean of 5, 10, 15, and z is 20. what is z
Answer:
z = 50
Step-by-step explanation:
There are 4 numbers in total (5,10,15,z)
The mean is when you get the total of all the numbers and divide by how many there are
If you do the inverse then that means that 20 x 4 = total of all 4 numbers
80 = 15 + 10 + 5 + z
80 = 30 + z
z = 80 - 30
z = 50
You can check you answer at the end

11. A scuba diver's elevation changed by -123 feet every minute. This was
1½ times the rate of change for a second scuba diver. What was the rate of
change in elevation of the second scuba diver in feet per minute?
Answer:
The rate of change in elevation for the second scuba diver is -82 feet per minute.
Step-by-step explanation:
-123 feet every minute.
1.5x more than 2nd diver.
-123/1.5 = 2nd diver rate
2nd diver rate = -82
The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.
Given that, a scuba diver's elevation changed by -123 feet every minute.
What is constant rate of change?When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.
1½=1.5 times the rate of change for a second scuba diver
Now, rate of change in elevation of the second scuba diver
= -123/1.5
= -82 feet per second
Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Answer: Company B charges $0.08x + $30.00 more than Company A for x miles.
Step-by-step explanation:
The total cost for Company A for x miles is 0.09x + 30.50, and the total cost for Company B is 0.17x + 60.50. To find how much more Company B charges than Company A for x miles, we can subtract the cost of Company A from the cost of Company B:
(0.17x + 60.50) - (0.09x + 30.50)
Simplifying the expression, we get:
0.08x + 30.00
Therefore, Company B charges $0.08x + $30.00 more than Company A for x miles.
