Solve 12n+7p - 6n = 25p for n.

Mathematics
1 answer:
Kryger [21]3 years ago
5 0

Answer:

n = 3p

Step-by-step explanation:

12n + 7p - 6n = 25p; solve for n

First we will add like terms in the left side

12n - 6n + 7p = 25p

6n + 7p = 25p

Subtract 7p to both sides

6n + 7p - 7p = 25p - 7p

6n = 18p

Now divide 6 from both sides

6n/6 = 18p/6

n = 3p

A company makes two sizes of cylindrical shaped boxes. The ratio of the heights is 5:7.
Dmitrij [34]

Answer:

The volume ratio is also 5 : 7

Step-by-step explanation:

The volume of a cylinder is given by the following formula:

volume = pi*r²*h

Since we have two cylinders and their height varies at a ratio of 5:7 we can say that the smaller one has a height of "h" while the bigger has height of "(7/5)*h". Thefore their volume is:

volume smaller = pi*r²*h

volume bigger = pi*r²*(7/5)*h

volume bigger = (7/5)*pi*r²*h

The ratio of their volume is given by the division of the smaller volume by the bigger one:

volume ratio = volume smaller / volume bigger

volume ratio = (pi*r²*h) / [(7/5)*pi*r²*h] = 1/(7/5)

volume ratio = 5/7

The volume ratio is also 5 : 7.
