What is equivalent expression of 6x(5+n)

dalvyx [7]

Answer:

12762.72 cubic meters

Step-by-step explanation:

The volume of a cylinder is denoted by the formula: $V=\pi r^{2} h$ , where r is the radius and h is the height.

Here, we see that the height h = 11.5 m. We also see that the diameter is 37.6 meters. Since diameter = 2 * radius, we can divide this number by 2 to get the radius: r = 37.6/2 = 18.8 meters.

Now substitute these values into the equation:

$V=\pi *(18.8^2)*11.5=3.14*(18.8^2)*11.5=12762.72$ cubic meters

Hope this helps!

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel. How old is Kevin now?

GuDViN [60]

Let k and d be the Kevin's age and the Daniel's age;
We have the equation:
k = 3 + d;
k - 2 = 4( d - 2 );
We have 3 + d - 2 = 4d - 8;
Then, d + 1 = 4d - 8;
9 = 3d;
d = 3.
Finally, k = 6 years.

Suppose you have a tablet with a capacity of 35 gigabytes. for a plain text book, one byte typically corresponds to one charact

steposvetlana [31]

The first thing we must keep in mind is the following unit conversion:
$1 gigabytes = 1 * 10 ^ 9 bytes
$
We have then that for 35 gigabytes:
$35 * (1 * 10 ^ 9) = 35 * 10 ^ 9 bytes
$

Part A:
For this case we make the following rule of three:
2000 bytes --------------> 1 page
35*10^9 bytes ----------> x
From here, we clear x:
$x = (35 * 10 ^ 9) / (2000)

x = 17500000 pages$

Part B:
Then, the number of 500-page books is:
$n = (17500000) / (500)

n = 35000
