Step-by-step explanation:

First of all simplify

That becomes

-5+25x - 8x -2= -4x -8x

Then bring together values with similarities

-5 -2 = -4x -8x -25x +8x

-7 = -45x

x = 7/45

What is the volume of this solid? A. 1104 B. 132 C. 96 D. 276

statuscvo [17]

For this case we have that the volume of the figure is composed of the volume of a prism and the volume of a pyramid:

The volume of the prism is given by:

$V = A_ {b} * h$

Where:

$A_ {b}$ : It is the area of the base

h: It's the height

Substituting: $V = 6 * 6 * 6\\V = 216 \ units ^ 3$

The volume of the pyramid is given by:

$V = \frac {1} {3} * L ^ 2 * h$

Where:

$L ^ 2:$ It is the area of the base

h: It's the height

Substituting:

$V = \frac {1} {3} * 6 ^ 2 * 5\\V = \frac {1} {3} * 36 * 5\\V = 60units ^ 3$

We add and we have:

$V = 276 \ units ^ 3$

I read 1/3 of a book in an hour. How much more of the book will I read in 2 1/5 hours

Verizon [17]

Answer:

Step-by-step explanation:

To find the number of pages of the book in the given hour:

To find the number of pages in 2 1/5 hours, multiply the number of pages read in 1 hour by 2 1/5 hours.

$\sf \text{ Number of pages read in 2 $\dfrac{1}{5}$ hours = $\dfrac{1}{3}*2\dfrac{1}{5}$ }$

$\sf = \dfrac{1}{3}*\dfrac{11}{5}\\\\=\dfrac{11}{15}$

$\sf \text{Number of pages read more in 2 $\dfrac{1}{5}$ hours = $\dfrac{11}{15}-\dfrac{1}{3}$}$

$\sf =\dfrac{11}{15}-\dfrac{1*5}{3*5}\\\\=\dfrac{11}{15}-\dfrac{5}{15}\\\\=\dfrac{6}{15}$
