Well there is two ways that you an solve this equation. So I will tell you both and you can pick which one you prefer to use. Anyone is fine by me not that it really matters but anyways here it goes.
First way is... You want to find out what 15% off $63 so a way to do it is you first want to find out what 10% of $63 is which would be 6.3 because you jus have to move the decimal place to the left one place. Which leaves you with the left over 5% which is half of the 10% which we have got 6.3 so half of that would be 3.15. So add those together and you get 9.45. I hope this is what you wanted to know.
Just because!!!
The other way that you could have done it is that you could have done it the decimal way... $63x0.15 to get 9.45 the same answer as above.
Answer: The world's population in 2015 would have been 7.333 billion.
Step-by-step explanation:
- Since the increase in population is an exponential one. It then follows a geometric progression defined by,
= 
- Where
is the nth term, <em>a</em> is the 1st term, <em>r</em> is the common ratio.
- Therefore, the population in <u>1998</u> is the <u>first term</u> <em>a</em> = 5.937 billion. The population in <u>2014</u> corresponds to the <u>17th term </u>(i.e., <em>n </em>= 17) = 7.238 billion.
Hence,
= 
7.238 billion = 5.937 billion × 
= (7.238 billion) ÷ (5.937 billion)
= 1.219
<em>r</em> = ![\sqrt[16]{1.219}](https://tex.z-dn.net/?f=%5Csqrt%5B16%5D%7B1.219%7D)
<em>r</em> = 1.0125
To get the population in 2015, which is the 18th term. We use
= 
= 5.937 billion × 
= 5.937 billion ×
= 5.937 billion × 1.235
= 7.333 billion
Answer:

Step-by-step explanation:
Two points are given to us and we need to find the slope of the line that passes through these two points . The two points are (-2,-3) and (5,4) .As we know that the slope of the line is given by
<u>Slope </u><u>of </u><u>a </u><u>line </u><u>is </u><u>:</u><u>-</u>

On using this formula we can find the slope of the line .
<u>Putting</u><u> the</u><u> </u><u>respective</u><u> values</u><u> </u><u>:</u><u>-</u>
672,591 is rounded to 700,000.
