Answer:
Percentage of interest at which the money is invested = 5%
Time for which the money is invested = 3 years
The final amount after 3 years = $820
Let us assume the principal amount = x dollars
We can conclude that the principal amount invested was $708.35.
Answer:
27 inches
Step-by-step explanation:
We are using the Pythagorean theorem
a^2 +b^2 = c^2 where c is the hypotenuse
We are given the diagonal, which is the hypotenuse and a leg
36^2 + b^2 = 45^2
Subtract 36^2 from each side
36^2 + b^2 - 36^2 = 45^2 - 36^2
b^2 = 45^2 - 36^2
b^2 =2025-1296
b^2 =729
Take the square root of each side
sqrt(b^2) = sqrt(729)
b =27
Answer:
Dependent
Step-by-step explanation:
and 
Lets solve the second equation for y and then substitute it in first equation

Subtract 6x on both sides

Divide by 2 on both sides

Now we plug it in first equation for y

Add 3x on both sides

Both sides are same, they are equal. the system has infinite solutions.
They are said to be dependent
The answer would be 4.6 (repeating).
