The final amount in the account after 25 years is $24670.42.
<h3>
How do you calculate the final Amount after 25 Years?</h3>
Given that 3400 dollars are placed in an account with an annual interest rate of 8.25% for 25 years.
The final amount in the account is calculated by the formula given below.
Where A is the final amount, P is the initial principal balance, R is the interest rate, T is the time period.
The final amount is given below.
Hence we can conclude that the final amount in the account after 25 years is $24670.42.

This is a system of equations. We can solve it by recognizing the two linear equalities we've given to solve this equation.
First, let's start off by recognizing two variables: x and y. x will be our number of hard puzzles, and y will be our number of easy puzzles. We're given that the number of hard puzzles and easy puzzles sum to 50, so we can rewrite that as:
Next, we're given that the sum of the points gained from the hard puzzles (60x), and the number of points gained from the easy puzzles (30y), sum to 1950. We can rewrite that as:
Now, we have our two linear equations, and we must solve for the hard puzzles, so x. Solving for the hard puzzles means eliminating the easy puzzles from our systems, so we can multiply our first equation by 30, and subtract it from the first equation. This is a technique called elimination.
Since x=15, Tina has solved 15 hard puzzles.
Your correct it’s the first one
Answer:
134/25
Step-by-step explanation:
5 9/25 > 5 * 25 = 125 + 9 = 134. > 134/25
(0,0) is the origin of a graph, so both W and W' remain at the origin.
The other 3 vertices double in size:
If you multiply all the numbers in X, Y and Z by 2, they become the numbers in X', Y' and Z'.
X(1,2) x 2 = (1*2,2*2) = X'(2,4)
Y(4,2) x 2 = (4*2, 2*2) = Y'(8,4)
Z(3,0) x 2 = (3*2, 0*2) = Z'(6,0)
That means the scale factor is 2
