The length of a rectangle exceeds its width by 4

Mathematics

Answer:

length = 10 in, width = 6 in

Step-by-step explanation:

Let the width be x.

Then, length = (x+4)

Area = 60 in²

Area of a rectangle = width × length

60 = x × (x+4)

60 = x² + 4x

x² + 4x - 60 = 0

Splitting the middle term :-

x² + 10x - 6x - 60 = 0

x (x + 10) - 6 ( x + 10) =0

(x + 10) ( x - 6)

x = -10 (doesn't fulfill our requirement)

x = 6

So, width = 6 in

length = 6+4 = 10 in

One estimate of the population of the world on January 1, 2005, is
inn [45]

Answer:

8,566,379,470 people

Step-by-step explanation:

Let's start simple.  In order to find the population increase on January 1, 2006, we need to multiply 6,486,915,022 by 1.4% and add it to 6,486,915,022.

  1. 6,486,915,022*1.4% = 90,816,810.308
  2. 90,816,810.308+6,486,915,022 = 6,577,731,832.31 people on January 2006.

Note that the above two steps gives the same answer as 6,486,915,022*1.014.

So we need to do this for each year.  20 years pass between 1/1/2005 and 1/1/2025.  

We need to do 6,486,915,022*1.014*1.014*1.014... 20 times.

This is equivalent to 6,486,915,022*1.014^{20}.

Multiplying it out gives us 8566379470.2 = 8,566,379,470 people.

If f(x) = 6x − 5 and f(5a) = 73, then what is the value of a?
Dmitrij [34]

Answer:

a =13/5

Step-by-step explanation:

f(x) = 6x − 5

f(5a) = 6*5a − 5=73

       30a -5 = 73

Add 5 to each side

    30a -5+5 = 73+5

      30a =78

Divide  by 30

30a/30 = 78/30

a =13/5
