Answer:

a. 80km/hr

b. 8 dollars an hour

c. 30 passengers on one bus

d. 6 degrees a minute

Step-by-step explanation:

You want to divide these down to the smallest rate possible, so you divide.

480/6=80

80 km/hr

56/7=8

8 dollars and hour

270/9=30

30 passengers in one bus

54/9=6

6 degrees in one minute

The length is 12 cm more than its width . Find the area of the rectangle if it's perimeter is 100 cm
DaniilM [7]
Let's say the width is (x) and the width is (x+12). The formula for a perimeter of a rectangle equals 2w + 2l, which would then for this problem be 100=2(x) + 2(x+12) which would distribute as 2x + 2x + 12 which equals 4x+12. When you subtract twelve from 100 you get 88=4x. Divide 88 by 4 and you get x=22. This then would mean the width is 22 and the length is 34. The formula for an area of a rectangle is w*l. Plug in the numbers that you figure out from the area formula and you get 22x34=748

A population of 2000 starfish has a yearly per capita population growth rate of 0.012. By next year, how do you expect populatio
Alona [7]

Answer:

It will increase by 24 starfish

Step-by-step explanation:

The population is modeled by the following differential equation:

\frac{dN}{dt} = rN

Which has the following solution:

N(t) = N(0)e^{rt}

In which N(0) is the initial population and r is the growth rate.

A population of 2000 starfish has a yearly per capita population growth rate of 0.012.

This means that N(0) = 2000, r = 0.012

By next year, how do you expect population size to have changed?

This is N(1).

N(t) = N(0)e^{rt}

N(1) = 2000*e^{0.012}

N(1) = 2024

2024 - 2000 = 24

So the correct answer is:

It will increase by 24 starfish
