The answer is 2/7 or 0.28571428... You can find this the same way as your other problem by finding the common denominator and multiplying. (Also, if you go on Mathway, you can find solutions to almost any problem really quickly.)
Hope this helps!

Answer:
4
Step-by-step explanation:
Every year, the world grows by 1.1%. Converting to a decimal, we can divide by 100 to get 1.1% = 0.011. This means that the world grows by 0.011 exponentially each year. To put this into an expression, we can add 1 to our percentage to get 1.011. This represents 1 = 100% (the original population) and the growth of 1.1% = 0.011. We multiply the rate including the growth by the population to get the population after one year. After the first year, we have
population * 1.011 as the new population after one year. We do that for every year, so the second year's population is population*(1.011)*(1.011) and so on. If x represents the amount of years, then the population can be represented as
(original population)*1.011ˣ
Therefore, to get from 7 billion to 7.31 billion, we have
7 billion * 1.011ˣ = 7.31 billion
divide both sides by 7 billion to relatively isolate the x
1.011ˣ = 7.31/7
Another way of writing this is
log (base 1.011) (7.31/7) = x
≈ 3.96
Rounding to the nearest whole number, we get 4 as our answer
Well what you need to do is <span>find the perimeter of both rectangles.
Rectangle A: ((2x+8)*2)+((x-1)*2)
Rectangle B: ((3x + 5)*2)+((2x-2)*2)
That will be </span>(10x+6)-(6x+14)=4x-8
Your answer will be D.
Hope this is useful
<u>Answer:</u>
24
<u>Step-by-step explanation:</u>
Let the number we are looking for =
.
∴ According to the question:
÷ 8 = 3
• Multiply both sides by 8:
= 8 x 3
= 24
Answer:
43
Step-by-step explanation:
there is a line above the 43, meaning that it ends in 434343434343434343434343434343...... You get the point.
