Answers

Answer:

125

Step-by-step explanation:

N150=120%

? =100

150×100/120

=125

The cost price of the good is $125.

What is cost price?

Cost price is the total amount of money that it costs a manufacturer to produce a given product or provide a given service.

Given that a good has been sold for $150 which made a profit of 20% we need to find the cost price of the good,

Let the cost price be x,

So,

x × 120% = 150

x = 150 × 100 / 120

x = 125

Hence the cost price of the good is $125.

Set up an algebraic equation and then solve.
The width of a rectangle is 14 units less than the length. If the area is 120 square
units, then find the dimensions of the rectangle.
Length:
Width:

Answers

Answer:

Width: 6

Length: 20

Step-by-step explanation:

So the area of a rectangle can be defined as: [tex]A=wl[/tex] where w=width and l=length.

In this case we don't know what the length is, so let's just say the length is the variable l, and since the width is 14 units less than the length, we can express it as (l-14). this gives us the equation: [tex]A=l(l-14)=l^2-14l[/tex]. We can solve for l, since we're given the area which is 120. So let's set the equation equal to that:

Original Equation:

[tex]A=l^2-14l[/tex]

Substitute 120 as A (given)

[tex]120=l^2-14l[/tex]

There is many ways to solve this equation: factoring, quadratic equation, completing the square etc... but in this case I'll just complete the square

Add (b/2)^2 to both sides to complete the square

[tex]120+(\frac{-14}{2})^2=l^2-14l+(\frac{-14}{2})^2[/tex]

Simplify

[tex]169=l^2-14l+49[/tex]

Rewrite right side a square binomial

[tex]169=(l-7)^2[/tex]

Take the square root of both sides

[tex]13=l-7\\[/tex]

Add 7 to both sides

[tex]20=l[/tex]

to solve for width simply subtract 14 from the length which is 20, so the width is 6

Width: 6

L: 20

Suppose that poaching reduces the population of an endangered animal by 6​% per year. Further suppose that when the population of this animal falls below 20​, its extinction is inevitable​ (owing to the lack of reproductive options without severe​ in-breeding). If the current population of the animal is 1500​, when will it face​ extinction? Comment on the validity of this exponential model.

Answers

If poaching reduces the population of an endangered animal by 6% and the criteria of population extinction is 20 with present population 1500 then it will take 3.62 years to reach to the mark of extinction.

Given Poaching reduces the population of endangered animals by 6% per year. The criteria of population extinction is 20. Present population being 1500.

Number of years taken by the population of endangered animals to reach to 20 mark can be calculated as under:

20=1500*[tex](1-0.06)^{n}[/tex]

20=1500*[tex]0.94^{n}[/tex]

20/1500=[tex]0.94^{n}[/tex]

take log both sides

log(0.133)=log[tex]0.94^{n}[/tex]-------1

log(0.133)=nlog (0.94)

put the values log values:

log(0.133)=-0.8761

log(0.94)=-0.0268

Taking 1

-0.8761=n*(-0.0268)

n=0.8761/0.0268
