Answer:

$\boxed {D) -\frac{2y}{x}}$

Step-by-step explanation:

Solving :

$\implies \mathsf {\frac{(-2xy^{2})^{3}}{4x^{4}y^{5}}}$

$\implies \mathsf {\frac{-8x^{3}y^{6}}{4x^{4}y^{5}}}$

$\implies \mathsf {\frac{-2y}{x}}$

Is the square root of 8 greater than, less than, or equal to 4 ?

Tom [10]

Answer:

√8 is less than 4

Step-by-step explanation:

We need to compare √8 and 4

To compare the numbers they should both be in the same format

√8 is not a perfect square so we'll put number 4 under root

4 = √4² = √16

Now we compare

√8 < √16

So √8 is less than 4

Each of the four sides of a swimming pool measures 12 m the pool is 6 m deep how much water will be needed to fill completely

Alex_Xolod [135]

The amount of water needed to fill the swimming pool completely is 864 cubic meters.

Given that each of the four sides of a swimming pool measures 12 m the pool is 6 m deep.

"Volume" is a mathematical quantity that indicates the amount of three-dimensional space occupied by an object or surrounding surface. Volume units are cubic units like m³, cm³, in³, etc.

As we know, the swimming pool is in cubic shape.

So, we will find the volume of cube using the formula V=l×b×h.

Here, l=12m, b=12m and h=m.

Now, we want to substitute the values in the formula, we get

V=12m×12m×6m

V=864m³

Hence, the amount of water needed to fill completely the swimming pool whose each of the four sides of a swimming pool measures 12 m the pool is 6 m deep is 864 cubic meters.

9. Determine the volume of concrete needed to build a ramp in the shape of a triangular prism to the nearest tenth of a cubic me

kogti [31]

Answer:

67.5

Step-by-step explanation:

I've learned this multiple ways but in my opinion this is the easiest. Just times everything together so, 40 x 2.5 x 1.2 which equals 135 and then divide 135 by 2 which equals your answer of 67.5 which is rounded to the nearestt tenth already.
