Answer : The required ratio is (14m-6):(8m+23) .

[tex]\rule{200}4[/tex]

Here we are given that the ratio of sum of first n terms of two AP's is (7n + 1):(4n + 27) .

That is.

[tex]\small\sf\longrightarrow \dfrac{S_1}{S_2}=\dfrac{7n +1}{4n +27} \\[/tex]

As , we know that the sum of n terms of an AP is given by ,

[tex]\small\sf\longrightarrow \pink{ S_n =\dfrac{n}{2}[2a +(n-1)d]} \\[/tex]

Assume that ,

Using this we have ,

[tex]\small\sf\longrightarrow \dfrac{S_1}{S_2}=\dfrac{\dfrac{n}{2}[2a + (n-1)d]}{\dfrac{n}{2}[2a' +(n-1)d'] } \\[/tex]

[tex]\small\sf\longrightarrow \dfrac{7n+1}{4n+27}=\dfrac{2a + (n -1)d}{2a' + (n -1)d' } . . . . . (i) \\[/tex]

Now also we know that the nth term of an AP is given by ,

[tex]\longrightarrow\sf\small \pink{ T_n = a + (n-1)d}\\[/tex]

Therefore,

[tex]\longrightarrow\sf\small \dfrac{T_{m_1}}{T_{m_2}}= \dfrac{ a + (n-1)d }{a'+(n-1)d'}. . . . . (ii)\\[/tex]

[tex]\longrightarrow\sf\small \dfrac{T_1}{T_2}=\dfrac{2a + (2n-2)d}{2a'+(2n-2)d'} . . . . . (iii)\\[/tex]

From equation (i) and (iii) ,

[tex]\longrightarrow\sf\small n-1 = 2m-2\\[/tex]

[tex]\longrightarrow\sf\small n = 2m -2+1 \\[/tex]

[tex]\longrightarrow\sf\small n = 2m -1 \\[/tex]

Substitute this value in equation (i) ,

[tex]\longrightarrow \sf\small \dfrac{2a+ (2m-1-1)d}{2a' +(2m-1-1)d'}=\dfrac{7(2m-1)+1}{4(2m-1) +27}\\[/tex]

Simplify,

[tex]\longrightarrow\sf\small \dfrac{ 2a + (2m-2)d}{2a' +(2m-2)d'}=\dfrac{14m-7+1}{8m-4+27}\\[/tex]

[tex]\longrightarrow\sf\small \dfrac{2[a + (m-1)d]}{2[a' + (m-1)d']}=\dfrac{ 14m-6}{8m+23}\\[/tex]

[tex]\longrightarrow\sf\small \dfrac{[a + (m-1)d]}{[a' + (m-1)d']}=\dfrac{ 14m-6}{8m+23}\\[/tex]

From equation (ii) ,

[tex]\longrightarrow\sf\small \underline{\underline{\blue{ \dfrac{T_{m_1}}{T_{m_2}}=\dfrac{ 14m-6}{8m+23}}}}\\[/tex]

She will ride 13 miles in one hour

Step-by-step explanation:

(8 2/3) / (2/3) = x / 1....8 2/3 miles to 2/3 hr = x miles to 1 hr

cross multiply

(2/3)(x) = (8 2/3)(1)

2/3x = 26/3

x = 26/3 * 3/2

x = 26/2...which equals 13....she will ride 13 miles in 1 hr

Hi! Hope you're enjoying your day!

First of all, the G.C.F. stands for

Greatest Common Factor

So we need to find the Greatest Common Factor of the polynomials.

And yea, polynomials have Greatest Common Factors as well.

So, let's find all the Greatest Common Factors. :)

First, we have

[tex]\bold{28x^2yz}[/tex] and [tex]\bold{16xy^2}[/tex]

What are the common factors of these polynomials?

Well, there are plenty of them, like 2, 2x, y...

What is the Greatest Common factor?

Is it Option A, 12xy?

No, because neither 28 nor 16 is divisible by 12.

So we cross out Option A.

Is it Option B, 8xy?

No, because 28 isn't divisible by 8, and remember, if a number is evenly divisible by another number, then that number is a factor.

Example: 8 is a factor of 16 (16÷8=2); 8 is not a factor of 28, because

28÷8=3.5 (a decimal, not a whole number)

Is it Option C, 4xy?

Yeah, it seems like Option C is the right option.

[tex]\huge\checkmark[/tex]Both 28 and 16 are divisible by 4

[tex]\huge\checkmark[/tex]Both polynomials have an x and a y in them

[tex]\rule{250}{2}[/tex]

Find the GCF:

[tex]\bold{5x^2y^4,\:10x^3y^5, \:and\:15xy^2}[/tex]

Once again, is it Option A, 5x^3y^5?

No, because

✘ 5 and 10 aren't divisible by 3

✘ None of the 3 polynomials has a 3y term

In other words, Option A is wrong.

How about Option B?

You should see right off the bat that 5 and 15 aren't divisible by 10.

So now we have 2 options left.

Is it Option C, 5xy²?

Well,

✓All 3 polynomials are divisible by 5

✓ All 3 polynomials have a y² term

✓ All 3 polynomials have an x term.

Hence, the answers are

[tex]\boxed{\boxed{\bold{1. \;Option\;C; 2.\;Option\;C.}}}[/tex]

Hope everything is clear.

Answer:

  800 cm³

Step-by-step explanation:

The volume is the product of the base area and the "height" of the prism. Here, the base can be considered to be a 10 cm × 12 cm rectangle with a 4 cm × 5 cm cutout. Its area will be ...

  A = (10 cm)(12 cm) -(4 cm)(5 cm) = 120 cm² -20 cm² = 100 cm²

The product of this base area and the 8 cm height of the prism is ...

  V = Bh = (100 cm²)(8 cm) = 800 cm³

The volume of the prism is 800 cm³.

The graph of the direct variation passes through the origin

From the graph, we have the following points

(x.y) = (0,0) and (2,10)

Where:

x represents the number of revolutions

y represents the distance in feet

The revolution per foot of travel (r) is then calculated as:

[tex]r = \frac{x_2 -x_1}{y_2 -y_1}[/tex]

This gives

[tex]r = \frac{2 - 0}{10 - 0}[/tex]

[tex]r = 0.2[/tex]

This means that, the revolution per foot of travel is 0.2

This is the reciprocal of the revolution per foot of travel

In (a), we have:

[tex]r = 0.2[/tex]

So, the slope is:

[tex]Slope = \frac 1{0.2}[/tex]

[tex]Slope = 5[/tex]

Hence, the slope of the graph is 5

Answer/Step-by-step explanation:

Explain the role of the GCF in factoring a polynomial.

The role of the GCF in factoring a polynomial is the largest monomial that divides evenly into each term. GCF is a factor that is shared by all terms within a polynomial. For instance, if we have a polynomial of the form A*B + A*C, the GCF is A since both terms have A as a factor.

Where is the GCF placed after factoring the GCF?

After factoring out the GCF, it's placed outside the parentheses, in front of the rest of the polynomial. Like the sample we previous use A*B+A*C = A(B+C).

How do you verify factoring is correct?

To Verify factoring is correct distributing the GCF to the polynomial within the parentheses.
