Answer:
a = 36 and a = 27
Step-by-step explanation:
The geometric mean of two numbers is the square root of the product of the two numbers.
Say for example we have the numbers x and y, the geometric mean z is mathematically;
z = √xy
For the first question, our z is 12, x and y are 4 and a respectively.
12 = √4a
square both sides
144 = 4a
a = 144/4
a = 36
For the second question
z is 9, x and y are 3 and a respectively
9 = √3a
square both sides
81 = 3a
a = 81/3
a = 27
The value of the square root of 140 lies between 11 and 12. The square root of 140 is 11.83
Answer: 58 months
Step-by-step explanation:
Let x represent the number of month to pay off the loan
$25,000 - $15,000 + $25x = 200x
Now it is simple algebra
10,000+25x= 200x Subtract 25 x from both sides
10,000 = 175x
x=57.14 month so Really 58 months till they pay it off
