Answer:

D.

7.68 × 108

Step-by-step explanation:

World population in 2013 was about 7.125 billion

In 2003 , it was about 6.357 billion

Increase = 2013 population- 2003 population

That’s 7.125 billion - 6.357 billion = 0.768 billion

A billion has 9 zeros. When you move The point one place to the right , it reduces the number of zeros by one. you now have

7.68 x 10^8

How many years is tween 1844 to2015
STatiana [176]
To find the number of years between 1844 to 2015 you have to subtract.

Lets say that x is the # of years in between 1844 and 2015

Then we have:
\sf{2015 - 1844 =x}

After doing the subtraction using a calculator or a pencil and paper, you get that:

\huge{\boxed{\bf{x=171}}}

So 171 years have passed from 1844 to reach to 2015.

Find two consecutive numbers with a product of 121
Crank
One number: x
Its consecutive:  x + 1

Product:

x(x+1)=121
x² + x - 121 = 0

Δ = 1² - 4.1.(-121)
Δ = 1+484
Δ = 485

As square root of 485 is not integer, do not exist two consecutive numbers with product of 121
