There are two sides (heads and tails). So one head would be 1/2, and one tail would also be 1/2.

Container A has 200 L of water, and is being filled at a rate of 6 liters per minute. Container B has 500 L of water, and is bei

Answer:

25 minutes

Step-by-step explanation:

Let the amount of time, in minutes, be x.

For Container A, we can write:

200 + 6x [since it has 200 and is being filled with 6 per minute]

For Container B, we can write:

500 - 6x [since it has 500 and is being drained with 6 per minute]

To find, we equate them and solve for x:

$200+6x=500-6x\\6x+6x=500-200\\12x=300\\x=\frac{300}{12}\\x=25$

<em>So, in 25 minutes (m), the two containers will have same amount of water</em>

Please help using law of cosines!

Answer:

∠ A ≈ 48°

Step-by-step explanation:

Using the Cosine rule to find an angle

cosA = $\frac{b^2+c^2-a^2}{2bc}$

with a = 10, b = 13 and c = 11

cosA = $\frac{13^2+11^2-10^2}{2(13)(11)}$

= $\frac{169+121-100}{286}$

= $\frac{190}{286}$ , thus

A = $cos^{-1}$ ( $\frac{190}{286}$ ) ≈ 48° ( to the nearest degree )
