Mathematics

antiseptic1488 [7]3 years ago
5 0

Answer:

h = 8 units

Step-by-step explanation:

We see similar triangles

AD = 20 - 4 = 16  units

since   AC = AD + DC = 16 + 4 = 20

so

16: h = h: 4   where corresponding sides are in proportion.

so ... cross multiply in this proportion and solve for h

64 = h^2

h = 8 units  it looks like choice F.)

Which of the following is equivalent to (5)^7/3
kifflom [539]
<em>The answer is \sqrt[3]{ 5^{7} }</em>

The reason we get this answer is because when you are converting from exponential form, to radical form you always place the numerator as our constant's exponent in the radical <em>( 5^{7} is called the radicand because it is located in the radical)</em> and the denominator in front of the radical, where it would be called the index. 

<em>Here's what a formula would look like:</em> ( \sqrt[n]{x} ) ^{q}=x^{ \frac{p}{q} }

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you further! :D

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.
