What is the value of x in the diagram below? If necessary, round your answer
dexar [7]

Answer:

\text{C. }7.2

Step-by-step explanation:

In the figure, all three triangles are similar. By definition, the corresponding sides of similar polygons must be in a constant proportion. Therefore, we can set up the following proportion to solve for x by dividing corresponding sides:

\frac{x}{12}=\frac{12}{20},\\20x=144,\\x=\frac{144}{20}=\boxed{\text{C. }7.2}

In a class room 3/10 of the students are wearing blue shirts and 3/5 are wearing white shirts there are 20 students In The class
shtirl [24]

Total number of students in the class = 36

Number of students wearing blue shirts = (1/6) * 36

                                                                = 36/6

                                                                = 6

Number of students wearing white shirts = (2/3) * 36

                                                                 = 2 * 12

                                                                 = 24

Then

Number of students not wearing blue or white shirts in the class = 36 - (6 + 24)

                                                                                                       = 36 - 30

                                                                                                       = 6

So 6 students in the class are wearing a shirt other than a blue or a white shirt. I hope the procedure is clear enough for you to understand.
