A submarine cruises underwater at 20 km/h and on

Darina [25.2K]

Answer:

System of equations:

20x + 30y = 650

x + y = 25

Time underwater = 10 hours

Time at the surface = 15 hours

Step-by-step explanation:

Let x = time underwater at 20 km/h.

Let y = time on the surface at 30 km/h.

speed = distance/time

distance = speed * time

distance underwater: 20x

distance on the surface: 30y

total distance: 650

20x + 30y = 650

total time: x + y

total time: 25

x + y = 25

20x + 30y = 650

x + y = 25

20x + 30y = 650

-20x - 20y = -500

--------------------------------

10y = 150

y = 15

x + y = 25

x + 15 = 25

x = 10

A used car was purchased in July 1999 for $11,900. If the car depreciates 13% of it's value each year, what is the value of the

trapecia [35]

1999 price = 11900
it depreciates 13%
$\frac{13}{100} \times 11900 = 1547$
year 2000 cost = 11900 - 1547 = 10353
it depreciates 13%
$\frac{13}{100} \times 10353 = 1345.89$
year 2001 cost = 10353 - 1345.89 = 9007.11
it depreciates 13%
$\frac{13}{100} \times 9007.11 = 1170.92$
year 2002 cost = 9007.11 - 1170.92 = 7836.19
