H (4.84) will be the correct answer

Answer: You are correct. The answer is choice (H) 4.84

======================================================

Explanation:

10% = 10/100 = 0.1

10% of 4.4 = 0.1*4.4 = 0.44

Increasing 4.4 by 10% means we add on 0.44 to get 4.4+0.44 = 4.84

So the ruler says 4.4 inches but the actual table could be as long as 4.84 inches.

---------

A shortcut is to compute it like this:

4.4*1.1 = 4.84

The multiplier 1.1 represents an increase of 10% because

1.1 = 1 + 0.1 = 100% + 10%

This shortcut allows for multiple percentage increases that can be chained together fairly quickly.

In 2007, the population of Ecuador was estimated at

swat32

Answer:

In 2012 , the population will be 15 million

Step-by-step explanation:

We start by setting up an exponential equation that defines the increase

P(t) = I(1 + r)^t

P(t) represents the present population = 15 million

I is the population in 2007 which is 13.8 million

r is 1.6% = 0.016

t is what we want to calculate

15 million = 13.8 million (1 + 0.016)^t

15/13.8 = (1.016)^t

1.09 = (1.016)^t

ln 1.09 = t ln 1.016

t = ln 1.09/ln 1.016

t = 5.429 which is approximately 5

So in 2007 + 5 = 2012, the population will be 15 million

The middle side of a triangle is half of 3 times the length of the shortest side. The longest side is 2 centimeters longer than

USPshnik [31]

Answer:

The difference between the longest and shortest sides of the triangle is 4 cm.

Explanation:

Step Number One:

Let the shortest side of the triangle have a length of x.

The middle side of the triangle has a length that is half of 3 times the length of the shortest side. This can be written as 1/2*3x, which equals 3/2x.

The longest side of the triangle has a length that is 2 centimeters longer than the length of the middle side. This can be written as 3/2x + 2.

Step Number Two:

The perimeter of the triangle, which can be found by adding the lengths of all of the sides of the triangle, is 18 centimeters. This can be shown by the following equations:

Shortest Side + Middle Side + Longest Side = Perimeter

x + 3/2x + 3/2x + 2 = 18

4x + 2 = 18

4x = 16

x = 16/4

x = 4

Step Number Three:

This means that the shortest side of the triangle has a length of 4 centimeters and the longest side of the triangle has a length of 8 centimeters.

8 cm - 4 cm = 4 cm
