Answer:    

3.78 cubic yards or just 4 to make things simple.

20 x 30 = 600 sqft x .17 or (2/12) = 102 cubic feet / 27 (cubic feet in a yard) = 3.78 cubic yards

Step-by-step explanation:

To cover a 27 ft by 34 ft garden with a 2 inch thick layer of topsoil, we would need approximately 5.75 cubic yards of topsoil from the store.

This question involves understanding dimensions and volume. In this case, the dimensions of the garden are given in feet (27 ft by 34 ft), and the desired thickness of the topsoil is 2 inches, which is approximately 0.167 feet. To calculate the volume in cubic feet, we multiply the length, width, and height.

The formula to calculate volume is: Volume = Length * Width * Height.

So, Volume = 27 ft * 34 ft * 0.167 ft = 153.234 cubic feet

Now, to convert this volume into cubic yards (since the store sells soil in cubic yards), we use the fact that 1 cubic yard = 27 cubic feet.

So, Volume = 153.234 cubic feet / 27 = approximately 5.676 cubic yards.

Given that the store only sells in increments of 1/4 cubic yards, we will need to round 5.676 up to the nearest quarter yard. This gives us 5.75 cubic yards.

Answer:

Part A: 379.94

Part B: 254.34

Part C: 125.6

Step-by-step explanation:

The are for the area of a circle is A = Pi*r^2

So for part A, do

A = 3.14 * 11^2

A = 3.14 * 121

A = 379.94

Same thing for Part B, just change the radius:

A = 3.14 * 9^2

A = 3.14 *81

A= 125.6

And for Part C, Subtract the area of the smaller from the area of the larger circle:

379.97 - 254.34 = 125.6

Answer:  √y  

Step-by-step explanation:

[tex]\sqrt[6]{y^3}=y^{\frac{3}{6}}=y^{\frac{1}{2}}=\boxed{\sqrt y}[/tex]

the way I get the subsequent term, nevermind the exponents, the exponents part is easy, since one is decreasing and another is increasing, but the coefficient, to get it, what I usually do is.

multiply the current coefficient by the exponent of the first-term, and divide that by the exponent of the second-term + 1.

so if my current expanded term is say 7a³b⁴, to get the next coefficient, what I do is (7*3)/5   <----- notice, current coefficient times 3 divided by 4+1.

anyhow, with that out of the way, lemme proceed in this one.

[tex]\bf ~~~~~~~~\textit{binomial theorem expansion} \\\\ \qquad \qquad (1+ax)^n\implies \begin{array}{llll} term&coefficient&value\\ \cline{1-3}&\\ 1&+1&(1)^n(ax)^0\\\\ 2&+\frac{(1)(n)}{1}\to n&(1)^{n-1}(ax)^1\\\\ 3&+\frac{n\cdot (n-1)}{2}&(1)^{n-2}(ax)^2 \end{array}[/tex]

so, following that to get the next coefficient, we get those equivalents as you see there for the 2nd and 3rd terms.

so then, we know that the expanded 2nd term is 24x therefore

[tex]\bf n(1)^{n-1}(ax)1 = 24x\implies n(1)(ax)=24x\implies nax=24x\implies n=\cfrac{24}{a}[/tex]

we also know that the expanded 3rd term is 240x², therefore we can say that

[tex]\bf \cfrac{n(n-1)}{2}~~(1)^{n-2}(ax)^2 = 240x^2\implies \cfrac{n(n-1)}{2}(1)(a^2x^2) = 240x^2 \\\\\\ \cfrac{(n^2-n)(a^2x^2)}{2}=240x^2\implies \cfrac{(n^2-n)(a^2)}{2}=\cfrac{240x^2}{x^2}\implies \cfrac{a^2n^2-a^2n}{2}=240 \\\\\\ a^2n^2-a^2n=480[/tex]

but but but, we know what "n" equals to, recall above, so let's do some quick substitution

[tex]\bf a^2n^2-a^2n=480\qquad \boxed{n=\cfrac{24}{a}}\qquad a^2\left( \cfrac{24}{a} \right)^2-a^2\left( \cfrac{24}{a} \right)=480 \\\\\\ a^2\cdot \cfrac{24^2}{a^2}-24a=480\implies 24^2-24a=480\implies 576-24a=480 \\\\\\ -24a=-96\implies a=\cfrac{-96}{-24}\implies \blacktriangleright a = 4\blacktriangleleft \\\\[-0.35em] ~\dotfill\\\\ n=\cfrac{24}{a}\implies n=\cfrac{24}{4}\implies \blacktriangleright n=6 \blacktriangleleft[/tex]

The expression equivalent to 8x - 12y + 32 is 4(2x - 3y + 8) after factorization by the greatest common factor.

Answer:

y=cos(0.4x)

Step-by-step explanation:

Answer:

The equation of the graph given is:

                  [tex]y=\cos(0.4x)[/tex]

Step-by-step explanation:

Clearly from the graph of the function that is provided to us we see that the graph repeats itself after every 5π.

i.e. the period of the function is: 5π.

Now we will check in each of the given options whose period is 5π.

We know that the period of a cosine function of the type:

[tex]y=cos(bx)[/tex] is given by:

[tex]Period=\dfrac{2\pi}{5}[/tex]

1)

[tex]y=\cos(\dfrac{x}{0.4})[/tex]

The period of this function is:

[tex]Period=\dfrac{2\pi}{\dfrac{1}{0.4}}\\\\\\Period=0.8\pi\neq 5\pi[/tex]

Hence, option: 1 is incorrect.

2)

[tex]y=\cos (5x)[/tex]

The period of this function is:

[tex]Period=\dfrac{2\pi}{5}\\\\\\Period=\dfrac{2}{5}\pi\neq 5\pi[/tex]

Hence, option: 2 is incorrect.

4)

[tex]y=\cos (\dfrac{x}{5})[/tex]

The period of this function is:

[tex]Period=\dfrac{2\pi}{\dfrac{1}{5}}\\\\\\Period=10\pi\neq 5\pi[/tex]

Hence, option: 4 is incorrect.

3)

[tex]y=\cos(0.4x)[/tex]

The period of this function is:

[tex]Period=\dfrac{2\pi}{0.4}\\\\\\Period=5\pi[/tex]

        Hence, option: 3 is the correct option.

Answer:

an = -8 +3(n-1)

an = -11 +3n

f(n) = -11 +3n

Step-by-step explanation:

–8, –5, –2, 1, 4, ...

This is an arithmetic sequence.

We are increasing by 3 each time

-8 +3 = -5

-5+3 = -2

-2 +3 = 1

The common difference is 3

The formula for an arithmetic sequence is

an = a1 +d (n-1)

an = -8 +3(n-1)

an = -8 +3n -3

an = -11 +3n

The nth term is -11 +3n

f(n) = -11 +3n

D. an = an-1+3; a1 = -8

Answer:

54 I think

Step-by-step explanation:

I just did 15 divided by 9 and got 5/3 and then did 90 divided by 5/3 and got 54

Final answer:

To find out how many sandwiches would have to be sold for 90 of the total number of sandwiches to be club sandwiches, set up a proportion using the given information: 9 club sandwiches out of 15 total sandwiches is equal to 90 club sandwiches out of x total sandwiches. Solve for x to find that 150 sandwiches would need to be sold in total for 90 of them to be club sandwiches.

Explanation:

To find out how many sandwiches would have to be sold for 90 of the total number of sandwiches to be club sandwiches, we can set up a proportion using the information given.

First, we know that out of the first 15 sandwiches sold, 9 were club sandwiches. This can be written as a ratio:

9 club sandwiches / 15 total sandwiches = 90 club sandwiches / x total sandwiches

Cross-multiplying, we get 9x = 90 * 15

Dividing both sides by 9, we find that x = 150

Therefore, if 150 sandwiches are sold, 90 of them would be club sandwiches.

[tex]1.999999\inf[/tex]

So adding a rational number, like 2, it would be irrational still:

[tex]2+1.999999\inf=3.999999\inf[/tex]

That being said, answer C is wrong

Now, what is 2/2? Or 4/1? Whole numbers are one of the 3 types of rational numbers.

[tex]2\ /\ 2=1\\\\4\ / 1=\ 4[/tex]

Thus the answer appears to be D

Now lets use the process of elimination to double check the answer:

The wording of your question is what will help us out here:

Which of the statements using operations on rational or irrational numbers always results in a rational number?

Because of that, any of the choices that involve a irrational number can result with another irrational number like so:

[tex]a)\ 1.999\inf+ 1.999\inf=3.888\inf\\\\b)\ 2.999\inf / 1.999\inf= 1.50025\inf[/tex]

And there you go, the only answer that hasn't been proven wrong is answer D.

The statement using operations on rational or irrational numbers always results in a rational number is d) rational ÷ rational​.

We know all the real can be subdivided into two parts one is rational numbers and the other is an irrational number.

Rational numbers are those numbers that have repeating or terminating digit patterns after the decimal place and irrational numbers are those numbers that do not have this property.

a) irrational + irrational is an irrational number, √3 + √3.

b) irrational ÷ irrational is sometimes rational and sometimes irrational,

√3 ÷ √3 = 1 but √6 ÷ √3 = √2.

c) rational + irrational is always an irrational number.

d) rational ÷ rational is always a rational number.

Answer:

y intercept is 1  1/3

equation is y = -1/6x + 4/3

x coordinate is -70  (-70,13)

Step-by-step explanation:

find M

m = 1 - (-1)/ 2 -1 4

m = -2/12 = -1/6

Find y intercept--Plug m and one point from above into y = mx + b

1 = - 1/6 (2) + b

1 = -2/6 + b

1  2/6 = b

1  1/3 = b

4/3 = b

To find the x coordinate if y is 13

13 = -1/6 x + 4/3

11 2/3 = -1/6 x

-70 = x

The y intercept of line AB = [tex](0,\dfrac{4}{3})[/tex]

The equation of line AB will be

[tex] y=\dfrac{-1}{6}x+\dfrac{4}{3}[/tex]

The x-coordinate of C = 4

The slope of line AB with coordinates of A and B are (14, -1) and (2, 1)

[tex]m_1=\dfrac{1-(-1)}{2-14}=\dfrac{2}{-12}=\dfrac{1}{-6}[/tex]

The equation of line AB will be

[tex](y-1)=\dfrac{1}{-6}(x-2)\\\\\Rightarrow y=\dfrac{1}{-6}(x-2)+1\\\\\Rightarrow\ y=\dfrac{-1}{6}x+\dfrac{1}{3}+1\\\\\Rightarrow y=\dfrac{-1}{6}x+\dfrac{4}{3}[/tex]

Put x=0, we get the [tex]y=\dfrac{4}{3}[/tex] i.e. [tex](0,\dfrac{4}{3})[/tex] is the y intercept of line AB.

Since, Line AB and Line BC form a right angle at their point of intersection, B. The the product of their slope must be -1.

Therefore, the slope of BC =[tex]m_2=\dfrac{-1}{m_1}=6[/tex]

Let x coordinate of C be a,then the coordinates of C = (a,13)

Now, slope of BC with points B(2,1) and C(a,13) will be

[tex]\dfrac{13-1}{a-2}=6\\\\\Rightarrow\ a-2=\dfrac{12}{6}\\\\\Rightarrow\ a-1=2\\\\\Rightarrow\ a=4[/tex]

Hence, the x-coordinate of C = 4
