The situation can be represented by expression 3x + 5y = 900

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Let x represent the number of cookies and y represent the number of cake slice.

The class wants to raise $900.Hence:

3x + 5y = 900

Answer:

1) 20 cm

2) 22.4 in

3) 15 ft

Step-by-step explanation:

For this question, you have to use the Pythagorean theorem.

Why?

Well, because it is a right triangle and you have 2 sides given and you want to find the third side.

Now let's solve this problem!

For number 1 we have:

a = 16 cm and B = 12 cm

you need to find the 3rd side which is c (aka the hypothenuse)

so let's write the equation:

a^2 + b^2 = c^2

Then we substitute with what we have given.

16^2 + 12^2 = c^2

Using a calculator solve the equation

400 = c^2

Now we have to find the square root from both sides of the equation.

c = 20 cm (That's the final answer)

For number 2 we have:

a = 10 in and b = 20 in

we follow the same steps as in number 1

a^2 + b^2 = c^2

10^2 + 20^2 = c^2

500 = c^2

c = 22.4 in (That's the final answer)

For number 3 we have:

a = 9 ft and b = 12 ft

a^2 + b^2 = c^2

9^2 + 12^2 = c^2

225 = c^2

c = 15 ft (That's the final answer)

Consider the following predator-prey systems of differential equations dx/dt = -x/2 + xy/2 + y, dy/dt = y(1 - y) - xy/2 + y.

fgiga [73]

Answer:

a) Prey: $\frac{dy}{dt}=y(1-y)-\frac{xy}{2+y}$

Predator: $\frac{dx}{dt}=\frac{xy}{2+y}-\frac{x}{2}$

b) they grow as a function y(1-y).

c) It will grow faster and probably exponentially,

Step-by-step explanation:

Prey

For prey population the rate of change is given by its own growth rate, it would be a constant times the variable, minus the rate at which it is preyed upon, usually it is represent a parameter times x and y.

So the differential equation could be:

$\frac{dy}{dt}=y(1-y)-\frac{xy}{2+y}$

Predator

By the other hand, the rate of change of the predator's population depends only the rate at which the predators eat preys, minus predator's intrinsic death rate.

$\frac{dx}{dt}=\frac{xy}{2+y}-\frac{x}{2}$

b) If there are no predators present the differential equation that models prey population will be:

$\frac{dy}{dt}=y(1-y)$

So they grow as a function y(1-y).

c) In the case of the population of prey is much grader than predator, it will grow faster and exponentially, because it we assume that preys have unlimited food supply.

I hope it helps you!
