Step-by-step explanation:

Answer:

x = 2, y = 2

Step-by-step explanation:

Looking at the equations,

x + 4y = 10

2x + 8y = 20

If x = 2, and y = 0 then it would look something like this:

2 + (4×2) = 10

Let's apply that to the next equation:

(2×2) + (8×2) = 20

In conclusion, x = 2, y = 2

There are 130 fern samples did the biologist collect.

What is fern and moss samples?

In contrast to ferns, which are vascular plants, mosses are nonvascular primitive plants that produce spores. Furthermore, unlike ferns, which have a plant body that is divided into real stems, leaves, and roots, mosses have none of these features. Ferns also have circinate vernation, which is not true of mosses.

Given:

A biologist collected 326 fern and moss samples. there were 66 fewer ferns than moss samples.

Let, f denotes the number of ferns collected and

m denotes the number of mosses collected

From the given information,

m + f = 326          ..(1)

m - 66 = f            ..(2)

Plug equation (2) in equation (1),

m + m - 66 = 326

           2m = 326 + 66

           2m = 392

             m = 196

Plug m = 196 in equation (2),

f = 196 - 66

f = 130

Hence, there are 130 fern samples did the biologist collect.

What is a derivative of a function?

The derivative of a function of a single variable at a chosen input value. It is the rate of change of a function with respect to a variable.

Let us consider,

Width of the printed part, in inches be 'x'

height of the printed part, in inches be 'y'

According to question,

Area of the printed part, in square inches = xy = 24

So,

y=24/x

width of the page, in inches = x + 2×1 = x+2

height of the page, in inches = y + 2×1.5 = y + 3

The area of the page (in square inches) is , A

= (x+2) (y+3)

= xy + 3x + 2y + 6

= 24 + 3x + 2y + 6

= 3x + 2y + 30

= 3x + 2×24/x + 30

= 3x + 48/x + 30

The minimum length can be found by calculating the derivative dA/dx, where A is the area of the paper

Solving the equation for dA/dx=0,

[tex] \frac{dA}{dx} = \frac{d(3x + \frac{48}{x} + 30)}{dx} [/tex]

[tex] \frac{dA}{dx} = 3 + \frac{48}{ {x}^{2} } [/tex]

[tex]\frac{dA}{dx} = 3 + \frac{48}{ {x}^{2} } = 0[/tex]

[tex]3 + \frac{48}{ {x}^{2} } = 0[/tex]

x = 4

then,

y = 24/4 = 6

The width and height of the paper are

x+2=4+2=6 and

y+3=6+3 =9

The dimensions of the page, so that the least amount of paper is used must be 6 inches wide by 9 inches tall.

Hence, the most economical length of the paper is 9 inches and the width is 6 inches.

Answer: The first and the last answer choice

Step-by-step explanation:

They are equal to 8k=20 because they are the same equation but reduced or increased by the same multiple.

Answer:

it's the first option, 3rd option, and fifth option because the rest of the equation cancels out on them (ex. for the first option, divide each side by 3 that would remove the •3 from each side and leave you with 8k=20)

One pipe takes 6 hours to fill the pool and the other takes 12 hours.

Pipe A fills 1/x of the pool per hour, and Pipe B fills 1/y of the pool per hour. In other words, A takes x hours to fill the pool and B takes y hours to fill the pool.

Together, they fill 1/x + 1/y of the pool per hour. So, 4 hours times that rate should equal 1 full pool, since together they take 4 hours to fill the pool. That gives you your first equation:

4(1/x + 1/y) = 1

You're also told that if one pipe fills half the pool and the other takes over to fill the rest, it will take 9 hours. We don't know how long Pipe A works, so call that number of hours t. Pipe B must work for 9 - t hours.

So, Pipe A, working for t hours, fills half the pool:

t(1/x) = 1/2

And Pipe B, working for 9 - t hours, fills half the pool:

(9-t)(1/y) = 1/2

You now have a system of three equations (because this is an exceptionally complicated pipe-filling-pool problem):

4(1/x + 1/y) = 1

t(1/x) = 1/2

(9-t)(1/y) = 1/2

Solve for t in that second equation, then plug it into the third equation:

t(1/x) = 1/2

t = x(1/2)

t = x/2

(9 - x/2)(1/y) = 1/2

Now you've got a system of two equations:

4(1/x + 1/y) = 1

(9 - x/2)(1/y) = 1/2

Solve for y in the second equation, then plug that into the first equation:

(9 - x/2)(1/y) = 1/2

(9 - x/2) = y(1/2)

2(9 - x/2) = y

18 - x = y    (this is a really nice-looking form of that equation; we'll use it again later)

4(1/x + 1/y) = 1

4(1/x + 1/(18-x)) = 1

4/x + 4/(18-x) = 1

(4(18-x))/(x(18-x)) + (4x)/(x(18-x)) = 1

(4(18-x) + 4x)/(x(18-x)) = 1

4(18-x) + 4x = x(18-x)

72 - 4x + 4x = 18x - x2

72 = 18x - x2

x2 - 18x + 72 = 0

(x - 6)(x - 12) = 0

x - 6 = 0    OR    x - 12 = 0

x = 6   OR    x = 12

So, Pipe A takes either x = 6 or x = 12 hours to fill the pool alone.

When Pipe A takes 6 hours to fill the pool, Pipe B takes 12. When Pipe A takes 12 hours to fill the pool, Pipe B takes 6.

These cases are equivalent, since the original problem makes no distinction between the pipes.

Hence, one pipe takes 6 hours to fill the pool and the other takes 12 hours.
