Answer:

B.   60x^8

Step-by-step explanation:

4x^2\sqrt{5x^4} \cdot 3\sqrt{5x^8} =

= 4x^2 \times 3 \sqrt{5x^4 \times 5x^8}

= 12x^2 \sqrt{25x^{4+8}}

= 12x^2 \sqrt{25} \sqrt{x^{12}}

= 12x^2 \times 5 \times x^6

= 60x^8

Draw an example of a composite figure that has a volume between 250 and 300 cubic units
sertanlavr [38]
The composite figure in the attached file

we know that

[the volume of the composite figure]=2*3*30+2*20*2-------> (180+80) units³
[the volume of the composite figure]=2*3*30+2*20*2-------> 260 units³

260 units³ < 300 units³
and
260 units³ > 250 units³

You are hiking and are trying to determine how far away the nearest cabin is, which happens to be due north from your current po
Natali [406]

Answer:

101.98 yards.

Step-by-step explanation:

Please refer to the diagram that I drew (sorry for the messiness; I do not own a stylus and so I was using my mouse to try to draw it).

Since the triangle is a right triangle, you can use SOH CAH TOA. In this case, you are trying to figure out the opposite length, but you are given the adjacent. So, we will use tangent to solve this (TOA = Tangent, Opposite over Adjacent).

The angle is 22.6 degrees, and the tangent of the angle is equivalent to the opposite length, x, divided by the adjacent length, 245 yards.

tan(22.6) = x / 245

x / 245 = tan(22.6)

x = tan(22.6) * 245

x = 0.4162598242 * 245

x = 101.9836569

So, you are about 101.98 yards from the cabin.

Hope this helps!
