Answer:

5/3

Step-by-step explanation:

2(4x - 3) + x = 3(2x - 1) + 2

8x - 6 + x = 6x - 3 + 2

9x - 6 = 6x - 1

3x = 5

x = 5/3

Answer:

9442 lb

Step-by-step explanation:

First find the volume of the tank.  This being a sphere, the volume is V =(4/3)π·r³.  Here the diameter is 17 ft, so the radius, r, is half that:  8.5 ft.

Then the volume of the sphere is V = (4/3)π·(8.5 ft)³, and half that (the volume of the hemisphere) is (2/3)π·72.25 ft³.

Water weighs 62.4 lb/ft³.  To find the weight of the water in the full tank, multiply the tank volume by this weight density 62.4 lb/ft³:

×

(2/3)π·72.25 ft³ · 62.4 lb/ft³ ≈ 9442 lb

Answer:

Exactly 3 factors

Step-by-step explanatin

The number 1001 is a composite number because 1001 can be divided by one, by itself and at least by 7, 11 and 13. A composite number is an integer that can be divided by at least another natural number, besides itself and 1, without leaving a remainder (divided exactly).

The factorization or decomposition of 1001 = 7•11•13. Notice that here, it is written in exponential form.

The prime factors of 1001 are 7, 11 and 13. It is the list of the integer's prime factors.

The number of prime factors of 1001 is 3.

Answer:

V = (4, 4 )

Step-by-step explanation:

Use the midpoint formula, the equation corresponding coordinates to the coordinates of the midpoint M

let V = (x, y ) , W = (8, 6 ) , then

[tex]\frac{x+8}{2}[/tex] = 6 ( multiply both sides by 2 )

x + 8 = 12 ( subtract 8 from both sides )

x = 4

and

[tex]\frac{y+6}{2}[/tex] = 5 ( multiply both sides by 2 )

y + 6 = 10 ( subtract 6 from both sides )

y = 4

coordinates of V = (4, 4 )

Step-by-step explanation:

Its asking if y was six what would x be. Then you get n.

Given:

The expression is:

[tex]x^2-3x+4+2x^2-x-12[/tex]

To find:

The terms and like terms in the expression.

Solution:

Terms: Variables, constants and product of variable and constants are known as terms which are separated by addition sign "+".

Like terms: The terms which contain same variables with same power are known as like terms.

The given expression is:

[tex]x^2-3x+4+2x^2-x-12[/tex]

It can be rewritten as:

[tex]x^2+(-3x)+4+2x^2+(-x)+(-12)[/tex]

Terms are [tex]x^2,-3x,4,2x^2,-x,-12[/tex].

Like terms are [tex]x^2,2x^2[/tex] and [tex]-3x,-x[/tex] and [tex]4,-12[/tex].

Answer:

The solution is (-1/2, -2)

Step-by-step explanation:

Given 6f-4g=1,6f-6g=5, write these in columnar form:

6f-4g=1

6f-6g=5

Change all of the signs in the first equation:

-6f + 4g = -1

 6f-6g=5

-------------------

     -2g = 4, and so g = -2

Substituting -2 for g in either equation enables us to find f.  Let's use the first equation:    6f - 4(-2) = 5 yields 6f + 8 = 5, or 6f = -3

Then f = -1/2 and g = -2.  The solution is (-1/2, -2)

Given:

The equation is:

[tex]\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{7}{12}[/tex]

To find:

The value of x.

Solution:

Formulae used:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

[tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex](a-b)(a+b)=a^2-b^2[/tex]

We have,

[tex]\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{7}{12}[/tex]

Taking LCM, we get

[tex]\dfrac{(x+1)^2-(x^2-1)^2}{(x-1)(x+1)}=\dfrac{7}{12}[/tex]

[tex]\dfrac{x^2+2x+1-(x^2-2x+1)}{x^2-1^2}=\dfrac{7}{12}[/tex]

On cross multiplication, we get

[tex]12(x^2+2x+1-x^2+2x-1)=7(x^2-1)[/tex]

[tex]12(4x)=7x^2-7[/tex]

[tex]48x=7x^2-7[/tex]

[tex]0=7x^2-48x-7[/tex]

Splitting the middle term, we get

[tex]7x^2-49x+x-7=0[/tex]

[tex]7x(x-7)+1(x-7)=0[/tex]

[tex](7x+1)(x-7)=0[/tex]

[tex]x=-\dfrac{1}{7},7[/tex]

Therefore, the values of x are [tex]-\dfrac{1}{7}[/tex] and [tex]7[/tex].

Answer:

g(x + 7) = 11x + 80

g(x) + g(7) = 11x + 83

Step-by-step explanation:

g(x + 7) = 11(x + 7) + 3 = 11x + 77 + 3 = 11x + 80

g(x) + g(7) = 11x + 3 + 11(7) + 3 = 11x + 3 + 77 + 3 = 11x + 83

Answer:

Step-by-step explanation:

The expected value of the spinner landing on pink will be 18.

The anticipated value is an extension of the weighting factor in statistical inference. Informally, the anticipated value is the simple average of a significant number of outcomes of a randomly selected variable that was separately chosen.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

If Kelly spins the spinner 120 times. The table is given below.

Color      Frequency

Pink               6

Purple          12

Yellow          9

Blue             13

Total           40

Then the probability of the pink color will be

p = 6 / 40

p = 0.15

Then the expected value of the spinner landing on pink will be

E(x) = 120 x 0.15

E(x) = 18

The expected value of the spinner landing on pink will be 18.
