Volume of lower cylinder = π * r^2 * 2h = 2πr^2h
Volume of upper cylinder = π * (2r)^2 * h = 4πr^2h
Volume of container = 2πr^2h + 4πr^2h = 6πr^2h
It took 18 minutes to fill the container of volume 6πr^2h, the it will take 2 * 18 / 6 = 6 minutes to fill the lower container of 2πr^2h.
Answer: 6 minutes

Tina wants to buy grass seed to cover her whole lawn, except for the pool. The pool is 7/12 m by 3 /14 m. Find the area the gras

eimsori [14]

Answer:

Since Tina wants to buy grass seed to cover her whole lawn, except for the pool, and the pool is 7/12 m by 3/14 m, to find the area the grass seed needs to cover the following calculation must be performed:

It is impossible to determine the area that the grass seed needs to cover, because we do not have the data of the total size of the lawn. Now, you can determine the size of the surface that should not be covered, which is the one that the pool occupies, namely:

7/12 x 3/14 = X

0.583333 x 0.2142 = X

0.1249 = X

Therefore, the grass seed should not cover about 0.1249 square meters.

Mathematical word describes both 27x and 6x in the expression 27x+6x?

Maslowich

The mathematical word describing both $27x$ and $6x$ in the expression $27x+6x$ is "<u><em>addition</em></u>"

<h3>How to form mathematical expression from the given description?</h3>

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For the given case, the terms were $27x$ and $6x$ and the expression formed from them is $27x+6x$

This means both the terms were added together, as denoted by '+' (called 'plus') sign.

When two terms are written with 'plus' sign in between, then that means they're added to each other and the result will be addition of both of their's values.

Thus, the mathematical word describing both $27x$ and $6x$ in the expression $27x+6x$ is <u><em>addition</em></u>"
