Answer:

30 yards of fence

Step-by-step explanation:

First, convert 60 feet to yards and 30 feet to yards. Remember, 1 foot= 3 yards.

60/3= 20 yards

30/3= 10 yards

Then you add the length and the width of the fence (in yards) to find the total yards of fence.

20+ 10= 30 yards of fence

To solve this problem you must apply the proccedure shown below:

 1. You must make a system of equations, as below:

 2. Let's call:

 x: the number of first class tickets bought.
 y: the number of coach tickets bought.

 3. Then, you have:

 x+y=7 (First equation)
 970x+370y=3790 (Second equation)

 x=7-y

 4. By substitution, you have:

 970x+370y=3790
 970(7-y)+370=3790
 y=5

 x=7-y
 x=7-5
 x=2

 Therefore, the answer is:

 - Number of first class tickets bought=2

 - Number of coach tickets bought=5

Lexi picked 2 7/10 pounds of strawberries. That afternoon, Lexi’s sister ate 7/8 of the strawberries. How many pounds of strawbe
gavmur [86]

3\frac{3}{35} pound of strawberry

Step-by-step explanation:

Given parameters:

    Pounds of strawberry picked by Lexi =2 \frac{7}{10}

    Pounds of strawberry eaten by Lexi sister = \frac{7}{8}

Unknown:

Pound of strawberry Lexi's sister ate = ?

Solution:

This is a fraction word problem.

  Let pound of strawberry eaten by Lexi's sister = K

We can establish that:

  Pound of strawberry eaten by Lexi sister x K = Pound of strawberry picked by Lexi

Mathematically we have:

         \frac{7}{8} x K = 2 \frac{7}{10}

             K =  \frac{27 x 8}{10 x 7} = \frac{216}{70}

            K = 3\frac{3}{35} pound of strawberry

A farm grows both beans and corn. Each year, beans earn $900 per acre and corn earns $600 per acre. The farm has a total of 58 a
beks73 [17]

Answer:

35 acres of beans and 23 acres of corn

Step-by-step explanation:

58 divided by 2 = 29 +8 = 35 x 900 = 31500

                          = 29 - 6 = 23 x 600 = 13800

                                                            = 45300

The differential equation in Example 3 of Section 2.1 is a well-known population model. Suppose the DE is changed to dP dt = P(a
LuckyWell [14K]

Answer:

Decreases

Step-by-step explanation:

We need to determine the integral of the DE;

dP/dt=P(aP-b)

dP=P(aP-b)dt

1/(dP^2-bP)dP=dt

We can solve this by integration by parts on the left side. We expand the fraction 1/P²:

1/(d-b/P)\cdot{P^2} dP

let

u=d-b/P

du/dP=b/P^2

dP=\int\limits {P^2/b} \, du

P=lnu/b

Substitute u in:

P=ln(d-b/P)/b

Therefore the equation is:

ln(d-b/P)/b=t

We simplify:

d-b/P=e^b^t

P=b/(d-e^b^t)

As t increases to infinity P will decrease
