I need help with this question about similar triangles

Mathematics
1 answer:
Colt1911 [192]3 years ago
6 0

Answer:

ST = 12 units

Step-by-step explanation:

Δ RAS and Δ TES are similar triangles, thus the ratios of corresponding sides are equal, that is, noting that SR = 21 - ST, thus

\frac{ST}{SR} = \frac{TE}{AR} substitute values

\frac{ST}{21-ST} = \frac{8}{6} ( cross- multiply )

6ST = 8(21 - ST)

6ST = 168 - 8ST ( add 8ST to both sides )

14ST = 168 ( divide both sides by 14 )

ST = 12

I hope this is what you need.

Answer/Step-by-step explanation:

<u>Given:</u>

Bracelets - $3

Necklaces - $6

<u>To Find:</u>

Complete the patterns in the first two columns for the cost of 0,1,2,3 and 4 pieces of jewelry. Write the ordered pair for the corresponding terms in the third column. Then graph the ordered pairs.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<u>Solve: </u>Complete the patterns in the first two columns for the cost of 0,1,2,3 and 4 pieces of jewelry.

<u>Bracelets:  </u>                                                      <u> Necklaces:</u>

0 = $0                                                               0 = $0

1= $3                                                                  1 = $6

2=$6                                                                  2 = $12

3=$9                                                                   3 = $18

4=$12                                                                  4 = $24

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<u><em>Solve: </em></u>Write the ordered pair for the corresponding terms in the third column.

Ordered Pair -

Two numbers written in a certain order.

Usually written in parentheses like this:

(12,13)

Where they cross over is the "0" point,

we measure everything from there.

The X Axis runs horizontally through zero

The Y Axis runs vertically through zero

(x, y )

Since it asking for Write the ordered pair for the corresponding terms in the third column.

Thus,

- Number of jewelry to cost -

we have:

Bracelets ⇒ ( 3, 9)

Necklaces ⇒ (3, 18)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Then graph the ordered pairs.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Solve for x <br><br> log(7x+1) = log(x-2) + 1
myrzilka [38]
Log(7x+1) - log(x-2) =1

log[(7x+1) / (x-2)] =1 or log[(7x+1) / (x-2)] =log10 (log10=1)

it means (7x+1) / (x-2) =10

Solving ===> x=7
