A certain forest covers an area of 3100. Suppose that each year this area decreases by 4.75% . What will the area be after 7 yea

e-lub [12.9K]

Answer:

Step-by-step explanation:

This can be represented as exponential decreasing function.

y = a(1 - r)t

a = starting amount

r = rate

t = years

y = 1600(1 - .0725)15

= 1600(.9275)15

= 1600(.32337673)

= 517.40

In 15 years, the forest will shrink in size to 517.40 km2

Roberto rented a truck from the Super Truck Company for 9 hours. There was a rental fee of $50. Allison rented a truck from Truc

gavmur [86]

Answer:

Hence, the hourly rental fee is $\$\: 12$ .

Step-by-step explanation:

Time for which Roberto rented the truck $=9$ hours.

Rental fee $=\$ \:50$

Time for which Allison rented the truck $=4$ hours.

Rental fee $=\$ \:110$

Both companies have the same hourly rental fee.

Let the hourly rental fee of both the companies be $x$ .

Both spent the same amount.

So, according to the question,

$\Rightarrow 50+9x=110+4x$

$\Rightarrow 9x-4x=110-50$

$\Rightarrow 5x=60$

$\Rightarrow x=\frac{60}{5}$

$\Rightarrow x=12$

Hence, the hourly rental fee is $\$\: 12$ .
