Help with this question please. Doesn't make sense at all.​
snow_lady [41]

Answer:

  a. FG ≈ 6.983 cm

  b. FH = 13.16 cm

Step-by-step explanation:

<h3>a)</h3>

Corresponding sides of similar triangles are proportional. This means ...

  FG/GH = CD/DE

  FG = GH(CD/DE) = (9.4 cm)(2.6/3.5) . . . . . . multiply by GH; fill in values

  FG ≈ 6.983 cm

__

<h3>b)</h3>

And ...

  FH/GH = CE/DE

  FH = GH(CE/DE) = (9.4 cm)(4.9/3.5)

  FH = 13.16 cm

__

<em>Additional comment</em>

Corresponding vertices are listed in the same order in the similarity statements. This means, for example, segment FG (which names the first two vertices in the name of ΔFGH) will correspond to segment CD (which names the first two vertices of ΔCDE).

What is the largest digit N for which 2345N is divisible by 6?
kotegsom [21]
Consider this option (this is not the only way):
1. according to the condition 2345N is divisible by <em>6</em>, it means, that N is even number (0;2;4;6 or 8).
2. <em>6</em>=3*2, then the number 2345N is divisible by 3 also. It means, that the number (2+3+4+5+N)=(14+N) is divisible by 3, where N={0|2|4|6|8}.
3. using items 1 and 2:
(14+4)=18; only 18 is divided by 3, it means that N=4.

answer: 4.

Note also, that only 23451; 23454 and 23457 are divided by 3. Only 2345<u>4</u> is divided by 6 (2345<u>4</u>/6=3909).
