Hey there!
A common ratio is just that number that you multiply or divide to each number that gets you the next in a geometric sequence. In this sequence, we know the numbers are getting bigger and we're multiplying, so we want to know what you're multiplying by the first number to get to the second. We can call this unknown number x. SO if we start with the first number and set up an equation, we get:
3x = 12
Divide both sides by 3
x = 4
Therefore, your common ratio is 4.
To check, you can multiply all the next numbers by 4 to see that it all checks out.
Hope this helps!

Step-by-step explanation:
16 days is 16/80 = 1/5 the time for 6 builders, so the number of builders required is 1/(1/5) = 5 times that:
5 × 6 builders = 30 builders
Hello,
Let's assume a the hypotenuse
b/a=sin 30°==>b=a/2
c/a=cos 30°==>c=√3 / 2 *a
(√3/2 a, a/2,a) are the sides of the triangle.
The price of the truck is 4500 dollars.
But he paid it into breakdown:
=> 1500 dollars first payment
=> 350 dollars = 10 months => 350 * 10 = 3500 dollars
=> Total = 3500 + 1500 = 5000 dollars
=> 5000 - 4500 = 500 dollars additional for 10 months
=> 500 / 10 = 50 dollars per month
=> 50 * 12 = 600 dollars for 1 year
=> 600 / 4500 = 13.33% of the yearly interest.
