Anna wants to buy a car in two years and wants to have $10,000 for the purchase. How much will Anna need to deposit today in an
Brut [27]

Answer:

Anna will need to deposit \$9,050.25

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=2\ years\\A=\$10,000\\ r=0.05\\n=12  

substitute in the formula above  and solve for P

10,000=P(1+\frac{0.05}{12})^{12*2}  

10,000=P(1.0042)^{24}  

P=10,000/(1.0042)^{24}    

P=\$9,050.25

Perform the indicated operation. Express answer as a simplified fraction (You may have
timofeeve [1]

Step-by-step explanation:

4 +  \frac{2}{3}  =  \frac{3 \times 4 + 2}{3}  =  \frac{14}{3}  = 4 \frac{2}{3}

\frac{67}{71}  \times  \frac{381}{399}  =  \frac{67 \times 381}{71 \times 399}  =  \frac{25527}{28329}  =  \frac{8509}{9443}

\frac{684}{795}  \div  \frac{24}{37}  =  \frac{684}{795}  \times  \frac{37}{24}  =  \frac{25308}{19080}  = 1.33

In the figure below, lines L and M are parallel and line AB = line BC = line AC. What is the measure of the exterior angle
Kryger [21]

Answer:

120º

Step-by-step explanation:

angles of an equilateral triangle are equal so..

180 ÷ 3 = 60º

to get the exterior m⦣C

180 - interior m⦣C = exterior m⦣C

180º - 60º = 120º
