PLEASE HELP ME!! 1.02: Triangle Similarity 1 What is the value of X?

Mathematics
1 answer:
hichkok12 [17]4 years ago
6 0

Answer:

<h2>x = 28</h2>

Step-by-step explanation:

ΔARP and ΔCRD are similar. Therefore the sides are in proportion:

\dfrac{AR}{CR}=\dfrac{PR}{DR}

We have:

AR = 10 + x

CR = x

PR = 15 + 42 = 57

DR = 42

Substitute:

\dfrac{10+x}{x}=\dfrac{57}{42}           <em>cross multiply</em>

42(10+x)=57x             <em>use distributive property</em>

(42)(10)+(42)(x)=57x

420+42x=57x         <em>subtract 42x from both sides</em>

420=15x            <em>divide both sides by 15</em>

x=28

PLZZ HELP!!! MATHS QUESTION!!!
Vesnalui [34]

Answer:

To complete this chart, all you have to do is replace the numbers in the "x" column with the variable "x" in the expressions. Here's what I mean.

For the problem "13-x", replace "x" with the 2. Replace the x with the 2 for the rest of the problems. Then repeat the substitution method (chart is attached so you can see what I mean) with the numbers 4, 6, 8, 10, and 12.

How many students can sit around a cluster of 7 square table? The tables in a classroom have square tops. Four students can comf
Sveta_85 [38]

Answer:

16 students can sit around a cluster of 7 square table.

Step-by-step explanation:

Consider the provided information.

We need to find how many students can sit around a cluster of 7 square table.

The tables in a classroom have square tops.

Four students can comfortably sit at each table with ample working space.

If we put the tables together in cluster it will look as shown in figure.

From the pattern we can observe that:

Number of square table in each cluster   Total number of students

                     1                                                                 4

                     2                                                                6

                     3                                                                8

                     4                                                                10

                     5                                                                12

                     6                                                                14

                     7                                                                16

Hence, 16 students can sit around a cluster of 7 square table.
