Answer:

10.8 km/hr

Step-by-step explanation:

Given that

radius of the diameter is 4 cm

Converting 4 cm to km, we have

4/100000 = 0.00004 km or 4*10^-5 km

Angular speed is given as

v = 2πr/T

Where T is, 1/n,and n is the number of revolutions

v = (2 * 3.142 * 0.00004) / (1/7000)

v = 0.00126 / 0.007

v = 0.18 km/min

This is in km/min, now we convert to km/hr as requested.

0.18 * 60 = 10.8 km/hr

[tex]\large \boxed{{m= \frac{3}{4} }}[/tex]

Step-by-step explanation:

Parralel lines have the same slope.

The slope will be [tex]\frac{3}{4}[/tex]

The line with a slope m = 3/4, the slope of the line parallel to this line will also be 3/4

The slope is the measure of the steepness of a line. It is also known as the gradient of a line.

Two parallel lines are known to have equal slopes. For example;

Therefore for the line with a slope m = 3/4, the slope of the line parallel to this line will also be 3/4

Answer:

25c+5d

Step-by-step explanation:

First, write out the equation as you have been given in the problem:

[tex]5(3c-[d-2(c+d)])\\[/tex]

Next, distribute the -2 to the set of parenthesis containing "c+d" and combine any like terms that you can:

[tex]5(3c-[d-2c-2d])\\5(3c-[-2c-d])[/tex]

Then, distribute the "-"to the "-2c-d" in the brackets and combine and like terms that you can:

[tex]5(3c+2c+d)\\5(5c+d)[/tex]

Finally, distribute the coefficient 5 to the terms inside the parenthesis:

[tex]25c+5d[/tex]

Therefore, 25c+5d is you simplified answer to the problem.

Answer:

x=9

Step-by-step explanation:

3x-2=25

Add 2 to each side

3x-2+2=25+2

3x = 27

Divide by 3

3x/3 = 27/3

x = 9

Answer:

x=9

Step-by-step explanation:

3x-2=25

3x =25+2

3x =27

x =27/3

x =9

Answer:

x=-1, x=2, x=3

Step-by-step explanation:

Factor the left side of the equation.

(x+1)(x^2+x-6)

(x+1)(x-2)(x-3)

Now set everything equal to 0

x+1=0

x-2=0

x-3=0

Now solve for x

therefore, the answer is x=-1, x=2, x=3

Since

[tex]\dfrac{x^3}{x^2+2x+1}=\dfrac{x^3}{(x+1)^2}[/tex]

we can perform synthetic division twice, first for

[tex]\dfrac{x^3}{x+1}[/tex]

then dividing the result by [tex]x+1[/tex] again.

...  ||  1     0    0    0

-1  ||        -1     1    -1

================

...  ||  1     -1    1     -1

This translates to

[tex]\dfrac{x^3}{x+1}=x^2-x+1-\dfrac1{x+1}[/tex]

Now divide [tex]x^2-x+1[/tex] by [tex]x+1[/tex]. (Dividing the remainder term by [tex]x+1[/tex] can wait until the end.)

...  ||  1    -1      1

-1  ||        -1     2

=============

...  ||  1    -2     3

or equivalently,

[tex]\dfrac{x^2-x+1}{x+1}=x-2+\dfrac3{x+1}[/tex]

Taking everything together, we have

[tex]\dfrac{x^3}{x^2+2x+1}=\dfrac{x^2-x+1}{x+1}-\dfrac1{(x+1)^2}[/tex]

[tex]\dfrac{x^3}{x^2+2x+1}=x-2+\dfrac3{x+1}-\dfrac1{(x+1)^2}[/tex]

Combine the last two fractions:

[tex]\dfrac{x^3}{x^2+2x+1}=x-2+\dfrac{3(x+1)-1}{(x+1)^2}[/tex]

[tex]\dfrac{x^3}{x^2+2x+1}=x-2+\dfrac{3x+2}{(x+1)^2}[/tex]

which agrees with the solution we found in your other question.

(There's a variant of synthetic division that works with directly dividing a polynomial by another one of any degree, but it's basically just a condensed version of applying the algorithm for dividing a polynomial twice by a linear one, like we've done here.)

Answer:

[tex] \boxed{\sf x = 14} [/tex]

Step-by-step explanation:

Solve for x:

[tex] \sf \implies 11 = \frac{1}{2} (x + 8)[/tex]

[tex] \sf 11 = \frac{1}{2} (x + 8) \: is \: equivalent \: to \: \frac{1}{2} (x + 8) = 11 : [/tex]

[tex] \sf \implies \frac{1}{2} (x + 8) = 11[/tex]

[tex] \sf Multiply \: both \: sides \: of \: \frac{1}{2} (x + 8) = 11 \: by \: 2 : [/tex]

[tex] \sf \implies \frac{1}{ \cancel{2}} (x + 8) \times \cancel{2 }= 11 \times 2[/tex]

[tex] \sf \implies 1(x + 8) = 11 \times 2[/tex]

11 × 2 = 22:

[tex] \sf \implies x + 8 = 22[/tex]

Subtract 8 from both sides:

[tex] \sf \implies x + (8 - 8) = 22 - 8[/tex]

8 - 8 = 0:

[tex] \sf \implies x = 22 - 8[/tex]

22 - 8 = 14:

[tex] \sf \implies x = 14[/tex]

The value of x is 4, for the equation 11 = 1/2 (x + 8).

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given equation is,

11 = 1/2 (x + 8)

Simplify the equation by multiplying 2 in both the sides,

11 × 2 =2 × 1/2 × (x + 8)

22 = x + 8

Subtract 8 from both the sides,

22 - 8 = x + 8 - 8

14 = x

or x = 14

The required value of x for the given equation is 14.

Answer:

C = 100

Step-by-step explanation:

PEMDAS

multiplication and division first from left to right so

125/25 = 5

5x5 = 25

25 + 75 = 100

Answer:

C. 100

Step-by-step explanation:

To complete this question you must use systems of equations.

First you must complete multiplication or division depending on which comes first in the left to right sequence. In this case it is 125/25 which equals 5. This now makes the equation 75+5 x 5

Next, you complete any other division or multiplication Which in this case is, 5x5. The answer to this is 25, making the new equation, 75+25 which when added together equals 100!

And that is how you use systems of equations. Hope it helps ;)

Answer:

[tex]\frac{4}{1}[/tex]

Step-by-step explanation:

Given:

2/20 : 1/40

A). First re-write the ratio as follows;

(i) Change the ratio sign to division (÷). i.e

2/20 ÷ 1/40

(ii) Solve the expression by changing the division to multiplication(×). This also means you will need to swap the numerator and the denominator of the second term. i.e (1 / 40) becomes (40 / 1)

(2/20) × (40 / 1) = [tex]\frac{2}{20}[/tex] × [tex]\frac{40}{1}[/tex] = [tex]\frac{4}{1}[/tex]

B). Now convert the result from above to unit rate. A unit rate is a rate in which the denominator has a value of 1.

So to convert   [tex]\frac{4}{1}[/tex]  to unit rate, we keep simplifying until the denominator becomes 1.

And since the denominator is already 1, there is no need for further simplification.

Therefore, 2/20 : 1/40 to unit rate is  [tex]\frac{4}{1}[/tex]

Answer:4/1

Step-by-step explanation:

I say this because you are supposed to divided it and the answer is 4 then you find the answer choice with a 1 as the denominator and it should say 4/1 and that is the correct answer.

= (2677 - 267)/900

= 2  61/90

Step-by-step explanation:

Hey, there!!

Let me simply clear you.

The given points are (6,2) and (-6,-8).

Remember if you are finding the equation of the line passing through point, you will get equation in slope intercept form.

As in your question there are two points we must use double point formula,

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]

[tex]( y - 2) = \frac{ - 8 - 2}{ - 6 - 6} (x - 6)[/tex]

Simplifying them we get,

6(y-2)= 5(x-6)

6y - 12 = 5x -30

Therefore, 5x - 6y - 18 = 0 is the required equation.
