Hello! For this question, we are compounding. The formula for compounding is P(1 + r)^t, where P = initial amount, r = rate, and t = time in years. In this problem, the rate is 1.2%. 1.2% is 0.012 in decimal form. Let's add 1 to that. 1 + 0.012 is 1.012. That part is done. Next, we raise it to the 7th power, because 2008 to 2015 is 7 years apart. 1.012^7 is 1.08708521101. This is a long decimal, but do not delete it from your calculator. Now, we multiply that number by 6.68 billion, which is 6,680,000,000 in standard form. When you do that, you get 7,261,729,209.52 or 7,261,729,210 when rounded to the nearest whole number. There. The world population will be 7,261,729,210 by 2015.
120 days in 4 months start day 1 with 4 rats every 4 days 4 rats add on so what I did is this.
Day 1= 4 rats day 4=8 day 8 = 12 so on intell u hit 118 days.but the answer to your question is.. there will be 114 rats if the population of rats double every 4 days for 4 months. hope this is correct and helps. :)
Answer:
x = 
Step-by-step explanation:
Given
-
x +
= - 
Multiply through by 60 ( the lcm of 4, 5 and 30) to clear the fractions
- 75x + 24 = - 26 ( subtract 24 from both sides )
- 75x = - 50 ( divide both sides by - 75 )
x =
= 
Answer: V = B · h
<u>Step-by-step explanation:</u>
Volume (V) = Area of the base (B) × height (h)
The Area of the base (B) depends on the shape of the base. For example:
- Triangular prism = Area of a Triangle × height
- Rectangular prism = Area of a rectangle × height
- Pentagonal prism = Area of a pentagon × height
