To solve the problem we must know about Scientific notations.

<h2>Scientific notations</h2>

The way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.

For example, 6,500,000,000,000 can be written as 6.5e+12.

The number of 221,000,000,000,000,000,000 can be represented as 2.21e+21.

<h2>Explanation</h2>

Given to us

  • 221,000,000,000,000,000,000

The above number can be written as 2.21e+21.

As in scientific notations, the number between 1 and 10 can only be represented, therefore, the number can be only 2.21e+21.

Hence, the number of 221,000,000,000,000,000,000 can be represented as 2.21e+21.

Given:<br> DBC = RST<br><br> Prove:<br> ABC &gt; RST
masya89 [10]

Answer:

<h3><ABC  >  <DBC.</h3>

Step-by-step explanation:

Given < DBC = < RST and we need to prove < ABC is greater than <RST.

First given statement:

< DBC = < RST

Reason: Given.

Second given statement :

<ABC = <DBC+  <ABD.

Reason: Angle addition theorem.

<em>Note: < ABC is the sum of angles <DBC and  <ABD and we have < DBC = < RST. So it's an obvious thing that the sum of angles <DBC and  <ABD is always greater than <RST.</em>

Also,  <ABC is greater than <DBC.

Therefore, correct option for third statement is :

<h3><ABC  >  <DBC.</h3>

Nesterboy [21]

25% of 30 can be found by converting 25% to a decimal and multiplying it by 30.

25% = 0.25

30x0.25=7.5

So x is 7.5.
