There are approximately Pi times 10,000,000 seconds in one ____?
MissTica

The number of seconds in a year are 31,557,600 seconds, which gives;

There are approximately Pi times 10,000,000 seconds in one <u>year</u>.

<u />

<h3>How can the given statement be completed?</h3>

The number of seconds in one day = 86,400

The number of seconds in one week = 604,800

The number of seconds in a year = 31,557,600

Therefore;

\mathbf{\dfrac{The \ number  \ of  \ seconds  \ in \  a \  year}{10,000,000}}  = 3.1557600 \ which  \ is \ close \ to \3.14159 \approx \pi

Which gives;

The number of seconds in a year ≈ π × 10,000,000

The completed statement is therefore;

  • There are approximately Pi times 10,000,000 seconds in one <u>year</u>

What is the similarity ratio of ΔABC to ΔDEF?<br> Tri ABC: AC=4 CB=5<br> Tri DEF: DF= 2
alekssr [168]

The similarity ratio of ΔABC to ΔDEF = 2 : 1.

Solution:

The image attached below.

Given  ΔABC to ΔDEF are similar.

To find the ratio of similarity triangle ABC and triangle DEF.

In ΔABC: AC = 4 and CB = 5

In ΔDEF: DF = 2, EF = ?

Let us first find the length of EF.

We know that, If two triangles are similar, then the corresponding sides are proportional.

⇒ \frac{AC}{DF} =\frac{BC}{EF}

⇒ \frac{4}{2} =\frac{5}{EF}

⇒ 4EF=5\times2

⇒ EF=\frac{5\times 2}{4}

⇒ EF=\frac{5}{2}

Ratio of ΔABC to ΔDEF = \frac{AC}{DF} =\frac{4}{2}=\frac{2}{1}

Similarly, ratio of ΔABC to ΔDEF = \frac{BC}{EF} =\frac{5}{\frac{5}{2}}=\frac{2}{1}

Hence, the similarity ratio of ΔABC to ΔDEF = 2 : 1.
