A Web site goes viral. The number of users triples each day. What is the constant percentage increase each day?
aksik [14]

We know that the number of users triple each day

Let number of users on day 1 be x

⇒ Users on day 2 = 3 * (x) = 3x

and Users on day 3 = 3 * (3x) = 9x

And so on...

% Increase in users from day 1 to day 2 = \frac{\text{Users on Day 2 - Users on Day 1}}{\text{Users on Day 1}} * 100

⇒ % Increase in users from day 1 to day 2 = \frac{3x-x}{x} * 100

⇒ % Increase in users from day 1 to day 2 = \frac{2x}{x} * 100

⇒ % Increase in users from day 1 to day 2 = 200%

Similarly,

% Increase in users from day 2 to day 3 = \frac{\text{Users on Day 3 - Users on Day 2}}{\text{Users on Day 2}} * 100

⇒ % Increase in users from day 2 to day 3 = \frac{9x-3x}{3x} * 100

⇒ % Increase in users from day 2 to day 3 = \frac{6x}{3x} * 100

⇒ % Increase in users from day 2 to day 3 = 200%

Hence, we can see that the percentage increase each day is 200%

How do you simplify 9*499 using the distributive property?
Temka [501]
<span>1. 9(499) = 4491 = (200 + 299)9

For the basic properties examples are:
Addition, you can have 6 + 107 = 113 </span>
<span>Commutative Property by moving: 107 + 6 = 113 </span>
<span>Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113 </span>
<span>Distributive Property by allotting: 2 (3) + 107 = 113   </span>

<span>Multiplication, you can have 6 x 107 = 642 </span>
<span>Commutative Property by moving: 107 x 6 = 642 </span>
<span>Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642 </span>
<span>Distributive Property by allotting: 2(3) x 107 = 642<span> </span></span>

Approximate the unknown side x in the diagram. <br> A. 3.356<br> B. 5.222<br> C. 3.064<br> D. 4.737
Marianna [84]

Answer:

The answer to your question is x = 3.356 cm

Step-by-step explanation:

This is a right triangle so we can use the Trigonometric functions to solve this problem.

Data

Ф = 40°

Adjacent side = 4 cm

Opposite side = x

Process

1.- We must know the lenght of the opposite side so we must use the tangent to solve it.

    tangent Ф = \frac{Opposite side}{Adjacent side}

2.- Solve it for Opposite side

    Opposite side = tanФ x Adjacent side

     Opposite side = tan 40° x 4

     Opposite side = 0.839 x 4

     Opposite side = 3.356

     Opposite side = x = 3.356 cm

a rectangular prism with a volumen of 10 cubic units is filled with cubes with side lengths of 1/2 unit​
algol13

40

I assumed that you wanted to know how much little cubes are in the big cubes...so.....first you need to find out the volume of the small cube : 1/2 x 1/2 = 1/4....then divide it with 10, then results with 40! :D
