an air conditioner can cool a room that has a volume of up to 3,600 cubic feet. a room shaped like a rectangular prism is 15 fee
valentinak56 [21]

The length of the air conditioner is 24 feet.

Volume = 3600 feet ³

Width = 15 feet

Height = 10 feet

Length = Unknown

Therefore, the value of the length will be calculated thus:

Volume = Length × Width × Height

3600 = Length × 15 × 10

Length = 3600 / (15 × 10)

Length = 3600 / 150

Length = 24

The length is 24 feet

sonja wants to have $14000 in 13 years. calculate how much she should invest now at 6% interest, compounded semiannually in orde
mariarad [96]
She should invest $6491.73.

The equation we use to solve this is in the form
A=p(1+\frac{r}{n})^{nt}, 
where A is the total amount in the account, p is the principal invested, r is the interest rate as a decimal, n is the number of times per year the interest is compounded, and t is the amount of time.

A in our problem is 14000.
p is unknown.
r is 6% = 6/100 = 0.06.
n is 2, since it is compounded semiannually.
t  is 13.

14000=p(1+\frac{0.06}{2})^{13*2}&#10;\\&#10;\\14000=p(1+0.03)^{26}&#10;\\&#10;\\14000=p(1.03)^{26}&#10;\\&#10;\\\text{Dividing both sides by }1.03^{26}\text{, we have}&#10;\\&#10;\\\frac{14000}{1.03^{26}}=\frac{p(1.03)^{26}}{1.03^{26}}&#10;\\&#10;\\6491.73\approx p

City planners are planning to build a new community pool. They agree that the pool will be rectangular in shape, but the propose
kobusy [5.1K]

The equation that can be used to determine the original length of the pool is 205.85 = 11.6(l + 3.7)

Let l be the original length of the pool.

Since the length of the pool is increased by 3.7 m, the new length L = l + 3.7.

Also, the area of the pool A = 205.85 square meter and it is a rectangle with width, W = 11.6 meters,

So, A = LW

Substituting the values of the variables into the equation, we have

A = LW

205.85 = (l + 3.7)11.6

So, the equation that can be used to determine the original length of the pool is 205.85 = 11.6(l + 3.7)
