Answer:

117 bags

Step-by-step explanation:

First day number of bags used by Raul=  3 bags

  We have to calculate the number of bags next three following days

On second day, number of bags used by Raul= 3×3=9

similarly, on third day number of bags used by Raul= 9×3=27

similarly, on fourth day number of bags used by Raul= 27×3=81

 Hence, the total number of bags used by Raul= 9+27+81=117

Hence, the correct answer is 117

What is the definition of math?
MAVERICK [17]

Answer:

Step-by-step explanation:

In simpler words mathematics is the study of numbers , quantities, or shapes.

It is the science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects. It deals with logical reasoning and quantitative calculation, and its development has involved an increasing degree of idealization and abstraction of its subject matter.

Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, architecture (ancient and modern), art, money, engineering, and even sports...

Solve 8x − 2(x + 1) = 7x + 8. (5 points)<br><br><br><br> 6<br><br> −6<br><br> −10<br><br> 10
sesenic [268]
First, simplify the equation.
8x - 2x - 2 = 7x + 8
Now subtract 8 on both sides to get rid of the one on the right side.
8x - 2x - 10 = 7x
Solve the left side.
6x - 10 = 7x
Subtract 6x from both sides.
-20 = x
Therefore, x = -20.

Convert the following numbers to engineering notation. Where applicable, solve and show answer in engineering notation. (8.2 × 1
snow_tiger [21]

Engineering notation of the number  (8.2 × 103) × (5.0 × 104) is

4.39192 × 10⁵

OR

4.4 ₓ 10⁵.

<h3>What is engineering notation ?</h3>

Engineering notation is same as scientific notation.

According to the given question

Converting (8.2 × 103) × (5.0 × 104) to engineering notation can be done using a base and raising it to the power of 10.

Base can be greater than or equal to 1 and less than 10.

Suppose base is a

∴ 1≤a<10 and the number in engineering notation will be of the form a×10ⁿ

Given (8.2 × 103) × (5.0 × 104) which is

=  844.6 × 520

= 439192

=4.39192 × 10⁵

= 4.4 ₓ 10⁵.
