The second side of a triangular deck is 3 feet longer than the shortest side and a third side that is 3 feet shorter than twice

matrenka [14]

Answer:

Shortest Side = 20 feet

Second Side = 23 feets

Third Side = 37 feets

Step-by-step explanation:

Let the shortest side of the desk be x. Hence,

Second side = (x + 3) feets

Third side = (2x - 3) feets

Perimeter = 80ft

x + (x + 3) + (2x - 3) = 80

4x = 80

x = 20

Hence, Second side = (20 + 3) feets

= 23 feets

Third side = (40 - 3) feets

= 37 feets

Hence<u>,</u><u> shortest side is 20 feets, Second side is 23 feets, Third side is 37 feets.</u>

Tawni watched 3/4 of a movie in 1 1/2 hours. Which is the length of the movie?

ella [17]

Answer:

2 hours.

Step-by-step explanation:

1 1/2 hours is equal to 90 minutes. We can calculate from this that 1/4 of the movie is equal to 30 minutes. To get the answer, we add the missing 1/4 of the movie (equal to 30 minutes) to get a total of 120 minutes, which is equal to two hours.

Good luck! Hope this helped!

Eli invested $ 330 $330 in an account in the year 1999, and the value has been growing exponentially at a constant rate. The val

Cloud [144]

Answer:

The value of the account in the year 2009 will be $682.

Step-by-step explanation:

The acount's balance, in t years after 1999, can be modeled by the following equation.

$A(t) = Pe^{rt}$

In which A(t) is the amount after t years, P is the initial money deposited, and r is the rate of interest.

$330 in an account in the year 1999

This means that $P = 330$

$590 in the year 2007

2007 is 8 years after 1999, so P(8) = 590.

We use this to find r.

$A(t) = Pe^{rt}$

$590 = 330e^{8r}$

$e^{8r} = \frac{590}{330}$

$e^{8r} = 1.79$

Applying ln to both sides:

$\ln{e^{8r}} = \ln{1.79}$

$8r = \ln{1.79}$

$r = \frac{\ln{1.79}}{8}$

$r = 0.0726$

Determine the value of the account, to the nearest dollar, in the year 2009.

2009 is 10 years after 1999, so this is A(10).

$A(t) = 330e^{0.0726t}$

$A(10) = 330e^{0.0726*10} = 682$

The value of the account in the year 2009 will be $682.
