Answer:

-1.2

Step-by-step explanation:

3n + 5 = 1/2(11n + 16)

3n + 5 = 5.5n + 8

5 = 2.5n + 8

-3 = 2.5n

-3/2.5 = n

-1.2 = n

Hope this helps!

Answer:

n=-1.2

Step-by-step explanation:

First, solve both sides of the equation:

3n+5=\frac{1}{2} (11n+16)

3n+5=(\frac{1}{2} )(11n)+(\frac{1}{2} )(16) (Distribute)

3n+5=\frac{11}{2} n+8

Then, subtract 11/2 n from both sides:

3n+5-\frac{11}{2}n=\frac{11}{2} n+8-\frac{11}{2} n

\frac{-5}{2}n+5=8

Now, subtract 5 from both the sides:

\frac{-5}{2} +5-5=8-5

\frac{-5}{2} n=3

For the last step, multiply both the sides by 2 / -5

(\frac{2}{-5} )*(\frac{-5}{2} )=(\frac{2}{-5} )*(3)

n=\frac{-6}{5}

Convert it to decimal:

n=-1.2

Evaluate ,where e is the solid that lies between the cylinders x^2+y^2=1 and x^2+y^2=16, above the xy-plane, and below the plane
MA_775_DIABLO [31]
Assuming you're just computing the volume, i.e.

\displaystyle\iiint_E\mathrm dV

we should convert to cylindrical coordinates first, setting

\begin{cases}x=r\cos\theta\\y=r\sin\theta\\z=\zeta\end{cases}

so that the volume is given by

\displaystyle\iiint_E\mathrm dx\,\mathrm dy\,\mathrm dz=\int_{\theta=0}^{\theta=2\pi}\int_{r=1}^{r=4}\int_{\zeta=0}^{\zeta=r\sin\theta+4}r\,\mathrm d\zeta\,\mathrm dr\,\mathrm d\theta

which has a value of 60\pi.

6 yards 9 feet 4 inches multiplied by 2
kirill115 [55]
1 yard is 3 feet
1 foot is 12 inches

Convert everything into inches:
9 x 12 = 108 in.
6 x 3 = 18 ft.
18 x 12 = 216

Add the inches together:
108 + 216 = 324 in

Multiply the inches by 2:
324 x 2 = 648 in

The answer is 648 inches.

(3a^4b)(5ab^2)-(a^5b^2)(9b)
Sliva [168]

Answer:

The expanded value of the given expression is

(3a^4b)(5ab^2)-(a^5b^2)(9b)=6a^5b^3

Step-by-step explanation:

Given expression is                                                                              

(3a^4b)(5ab^2)-(a^5b^2)(9b)

To find the value of the given expression:

(3a^4b)(5ab^2)-(a^5b^2)(9b)=15a^5b^3-9a^5b^3

(By multiplying the products and doing algebraci subtracion of the above expression)

Now taking the common terms in the above equation we get

(3a^4b)(5ab^2)-(a^5b^2)(9b)=3a^5b^3(5-3)

                                             =3a^5b^3(2)

                                             =6a^5b^3

Therefore the expanded value of the given expression is

(3a^4b)(5ab^2)-(a^5b^2)(9b)=6a^5b^3
