What is the volume of a cylinder, in cubic feet, with a height of 8 feet and a base diameter of 18 feet? Round to the nearest tenths place

under the same denominator r(r-4)

[6(r-4)] / (r(r-4)) + (4r) / (r(r-4)) = 1

(6r - 24 + 4r) / (r(r-4)) = 1

10r - 24 = r (r-4)

10r - 24 = r² - 4r

r² - 14r + 24 = 0

Δ = (-14)² - 4*1*24 = 100 = 10²

x' = (14 + 10) / 2 = 12

x" = (14 - 10) / 2 = 2

i'm french - so I answered as we learn in France :)

Answer:

In order from left to right: [tex]-\frac{4}{3}, -\frac{4}{5}, -\frac{2}{3}, \frac{7}{10}, \frac{7}{8}[/tex]

Step-by-step explanation:

[tex]-\frac{4}{3}[/tex] is the only improper fraction because the numerator is greater than the denominator and since it is negative, that means that it is the least.

[tex]-\frac{4}{5}[/tex] as the decimal -0.8 is closer to -1 than [tex]-\frac{2}{3}[/tex] as the decimal -0.666...

[tex]\frac{7}{8}[/tex] as the decimal 0.875 is closer to one than [tex]\frac{7}{10}[/tex] as the decimal 0.7...

Answer:

16ft

Step-by-step explanation:

It would be 16 feet because if you multiply 8 by 2 feet, you get 16ft.

Answer:

174

Step-by-step explanation:

Vectors are elements of the vector space, and they can be illustrated by diagrams.

The vector expression is given as:

2u - 1/3 v

Split the vector expressions, as follows:

[tex]y_1 = 2u[/tex]

[tex]y_2 = -\frac13v[/tex]

See attachment for the graphs of y1 and y2.

Next, we have:

[tex]y = 2u - \frac13v[/tex]

So, we have:

[tex]y = y_1 + y_2[/tex]

The above expression means that, we add the vectors y1 and y2 to get vector y

See attachment for the graph of 2u - 1/3 v

Answer:

2B / (mx) = y

Step-by-step explanation:

B = 1/2 mxy

Multiply each side by 2

2B = 2* 1/2 mxy

2B = mxy

Divide each side by mx

2B / (mx) = mxy / (mx)

2B / (mx) = y

Answer:

[tex] \huge y = \frac{2B}{mx} \\ [/tex]

Step-by-step explanation:

[tex]B = \frac{1}{2} mxy \\ [/tex]

Multiply through by 2 to eliminate the fraction

That's

[tex]mxy = 2B[/tex]

Divide both sides by mx to make y stand alone

We have

[tex] \frac{mxy}{mx} = \frac{2B}{mx} \\ [/tex]

We have the final answer as

[tex]y = \frac{2B}{mx} \\ [/tex]

Step-by-step explanation:

Before the change she made $230 a week because 11x16=176 + 18x3= 54

but after the change she would make $321 a week because 18x16= 233 + 11x3= 33

Answer:

I don't know

Step-by-step explanation:

it depends on your definition and question

Answer:

it has no solution.......

answer will be 3x+4 = 3x+4 i.e, 0=0 ,so

but if 3x+4 = 0 , x= -4/3 . Its a linear equation and has only one solution

Answer:

Infinitely many solutions.

Step-by-step explanation:

3x + 4 = 3x + 4

3x = 3x

Divide 3 from both sides.

x = x

Therefore, this equation has infinitely many solutions.

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

Example ~

x = 1

(3 × 1) + 4 = (3 × 1) + 4

3 + 4 = 3 + 4

Answer:

6.25 & 8.25

Step-by-step explanation:

im probably wrong lol-

29/2 = x+x+2

14.5=2x+2

12.5=2x

therefore x = 6.25 but to fin the other x add 2

so then the longer piece would be 8.25

[tex]\red\leadsto[/tex]Let one piece of glass tubing be of length x in ,

[tex]\green\leadsto[/tex]then other piece will be of length(x+2) in since it is 2 in longer than other piece

[tex]\\[/tex]

>>>Total length of both the piece

= 29 in _ _ _ (1)

>>>Total length of both pieces = length of shorter piece + length of longer piece

[tex]\:\implies[/tex] Total length of both pieces = x+(x+2) _ _ _(2)

[tex]\\[/tex]

Equating (1) and (2)

[tex]\:\implies[/tex]x+(x+2) = 29

[tex]\:\implies[/tex]x+x+2= 29

[tex]\:\implies[/tex]2x+2 = 29

[tex]\:\implies[/tex]2x= 29-2

[tex]\:\implies[/tex]x= 27/2

[tex]\\[/tex]

>>Length of smaller piece =

[tex]\:\implies[/tex]x = 27/2 in

>>> Length of larger piece =

[tex]\:\implies[/tex](x+2) = 27/2 + 2 = 31/2 in

[tex]\\[/tex]

[tex]\longrightarrow[/tex]Thus, The pieces are 27/2 in and 31/2 in long

Answer: Choice B)

[tex]804.2 \text{ km}^3[/tex]

This value is approximate.

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

Work Shown:

[tex]V = \pi*r^2*h\\\\V = \pi*8^2*4\\\\V = 256\pi\\\\V \approx 804.248 \text{ km}^3\\\\V \approx 804.2 \text{ km}^3\\\\[/tex]

I used the calculator's stored version of pi to get the most accuracy possible.
