Answer:
17 times
Step-by-step explanation:
Let "x" be the number of times today's investment is more than the investment 10 years ago
Investment 10 years ago = 1.25*10^3 = 1,250
Investment today = 2.125*10^4 = 21,250
So, we can form the equation as shown below:
1250*x = 21,250
x = 21,250/1,250
x = 17
Therefore, today's investment is 17 times greater than the investment 10 years ago
We can solve this in many ways, let's try this one.
T∧2 = 4 pi∧2 * a∧3 / GM First we will multiply whole equation with variable( or parameter) M and get
M * T∧2 = 4 pi∧2 * a∧3 / G After that we will divide whole equation with variable ( or parameter ) T∧2 and get
M = 4 pi∧2 * a∧3 / G * T∧2
This is correct answer
Good luck!!!
