The sum of the scientific notation is 8.655 * 10^9

<h3>Sum of  scientific notation</h3>

The standard form of a  scientific notation is expressed as A * 10^n

where

A is any value between 1 and 10

n is any integer

Given the expression below;

(8.42 x 10^9) + (2.35 x 10^8)

This can also be expressed as

(84.2 x 10^8) + (2.35 x 10^8)

(84.2+2.35) * 10^8

86.55 * 10^8

8.655 * 10^9

Hence the sum of the scientific notation is 8.655 * 10^9

mafiozo [28]

The numbering system we commonly use is called the decimal numbering system because it uses <u> 10 </u> symbols to represent all possible numbers.

A way of writing numbers is known as a number system.

There are the following number systems:

  1. Decimal number system: "Deci" meaning 10, implies that the number system consists of 10 digits or symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
  2. Binary number system: "Bi" meaning 2, implies that the number system consists of 2digits or symbols, namely 0, and 1.
  3. Octal number system: "Oct" meaning 8, implies that the number system consists of 8 digits or symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, and 8.
  4. Hexa-Decimal number system: "Hexa-Deci" meaning 16, implies that the number system consists of 16 symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.

Hence, we can say that the numbering system we commonly use is called the decimal numbering system because it uses <u> 10 </u> symbols to represent all possible numbers.

find the length of a segment indicated. Round your answer to the nearest tenth if necessary. NO LINKS. ​
Mademuasel [1]

Answer:

  8.  C) 24.2

  9.  A) 8.1

Step-by-step explanation:

8. The radius is shown as being 7.8 +4.3 = 12.1, so the diameter x is ...

  d = 2r

  x = 2(12.1) = 24.2

__

9. The unknown leg (y) of the right triangle can be found from the Pythagorean theorem.

  y² +11.7² = 12.5² . . . . . the radius is half the diameter

  y = √(156.25 -136.89) = √19.36 = 4.4

Then the segment of interest is ...

  x + y = 12.5

  x = 12.5 -4.4 = 8.1
