You deposit $20,000 in an account that pays 7.77% annual interest. Find the balance after 2 years when the interest is compounde

Mademuasel [1]

Answer:

The account balance after 24 months will be $23,092.70

Step-by-step explanation:

Given data

P= $20,000

r= 7.77%= 0.077

t= 2 years

A= ?

n= 24

The compound interest formula is

$A= P(1+t)^t$

Inserting our values to solve for A we have

$A= 20000(1+\frac{0.077}{24} )^2^*^2^4\\\\A= 20000(1+0.003 )^2^*^2^4\\\\A= 20000(1.003 )^2^*^2^4\\\A= 20000(1.003 )^4^8\\\A= 20000*1.15463517818\\\A= 23092.7035636\\\A= 23,092.70$

wariber [46]

Answer:

46.46 gallons

Step-by-step explanation:

we know that

An airplane consumes 30.25 gallons of fuel in 2.8 hours of flying

using proportion

Find out how many gallons will it consume in 4.3 hours of flying

$\frac{30.25}{2.8}\ \frac{gal}{h}=\frac{x}{4.3}\ \frac{gal}{h}\\\\x=30.25*(4.3)/2.8\\\\x= 46.46\ gal$

Sam's bank account balance on Monday was $8. On Tuesday, his account balance was -$2. How much money did Sam withdraw from his a

ss7ja [257]

It would be 8. To solve, look at it like this: 8-b=(-2). I would then look at a number line or create one if your not to sure of yourself. 8-8=0, and then 0-2=-2. 2+8=10 (the numbers you subtracted). So the answer is 10.

If 1/10m = 1/11m + 1/1100, what is the value of m?

valentinak56 [21]

$\frac{1}{10m} = \frac{1}{11m} + \frac{1}{1100} 
$
$\frac{1}{10m} = \frac{1*1100 + 1*11m}{11m*1100}$
$\frac{1}{10m} = \frac{1100 + 11m}{12100m}$
$1*12100m = 10m(1100 + 11m)$
$12100m = 11000m + 110 m^{2}$
$12100m-11000m = 110 m^{2}$
$1100m = 110 m^{2}$
m=10
