3400 dollars is placed in an account with an annual interest rate of 8. 25%. How much will be in the account after 25 years, to

OLEGan [10]

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.

$A = P ( 1 + \dfrac {R}{100})^T$

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.

$A = 3400 ( 1 + \dfrac {8.25}{100})^{25}$

$A = 3400 (7.256005874)$

$A = 24670.41997= 24570.42$

Hence we can conclude that the final amount in the account after 25 years is $24670.42.

I need help with this math question

ICE Princess25 [194]

Answer:

B. 5

Step-by-step explanation:

Step 1: Rewrite the equation a bit

$\frac{7^\frac{3}{4}}{7^\frac{x}{8}}=\sqrt[8]{7}\\7^\frac{3}{4}^-^\frac{x}{8}=7^\frac{1}{8}$

Step 2: Place a logarithm base 7 on both sides

$7^\frac{3}{4}^-^\frac{x}{8}=7^\frac{1}{8}\\log_77^\frac{3}{4}^-^\frac{x}{8}=log_77^\frac{1}{8}\\(\frac{3}{4}-\frac{x}{8})log_77=\frac{1}{8}log_77\\(\frac{3}{4}-\frac{x}{8})1=\frac{1}{8}1\\\frac{3}{4}-\frac{x}{8}=\frac{1}{8}$

Step 3: Solve for x

$\frac{3}{4}-\frac{x}{8}=\frac{1}{8}\\\frac{6}{8}-\frac{x}{8}=\frac{1}{8}\\-\frac{x}{8}=-\frac{5}{8}\\\frac{x}{8}=\frac{5}{8}\\x=5$

Neat exponent question :)

Hi I just really need help on this

Komok [63]

Answer:

3. 9 free throws. Proportion: 9/15

4. 18 free throws. Proportion: 18/24

Step-by-step explanation:

Multiply the number of free throws by the decimal of the percentage:

15*60%=15*.60=9

18*75%=18*.75=18.

The proportion is the number of free throws made over the total number of free throws attempted.

Hope this helps! :)
