Please help with this problem . Break it down for me 15-1/6n=1/6n-1

Lisa [10]

15-1/6n=1/6n-1
First, lets multiply both sides by 6 so that n is a whole number:
90-n=n-6
now you group like terms on each side, to do this you add n to each side and add 6 as well so it becomes:
96=2n
Now divide both sides by 2 so you have 'n' on one side and it is:
48=n

Hope this helps :)

Find the smallest number by which 2592 be multiplied so that the product is a prime factor

xeze [42]

Answer:

Step-by-step explanation:

2592 = 2×2×2×2×2×3×3×3×3

now,

√2592 = √2×2×2×2×2×3×3×3×3 = 2×2×3×3√2 = 36√2

as √2 is left so the number 2592 should be multiplied with 2 to get a perfect square.

Ships A and B are 1,425 feet apart and detect a submarine below them. The angle of depression from ship A to the submarine is 59

andreyandreev [35.5K]

Answer: The distance from ship B to the submarine is 1270.68 feet and the distance from ship A to the submarine is 1084.18 feet.

Step-by-step explanation:

Since we have given that

Distance between Ships A and B = 1425 feet

Angle of depression from ship A to the submarine =59°

Angle of depression from ship B to the submarine = 47°

As shown in the figure below:

Remaining angle will be

$180\textdegree-(47\textdegree+59\textdegree)\\\\=180\textdegree-106\textdegree\\\\=74\textdegree$

So, we will use "Sine formula ":

$\frac{\sin 74\textdegree}{1425}=\frac{\sin 59\textdegree}{B}\\\\B=\frac{1425\times \sin 59\textdegree}{\sin 74\textdegree}\\\\B=1270.68\ feet$

Similarly,

$\frac{\sin 74\textdegree}{1425}=\frac{\sin 47\textdegree}{A}\\\\A=\frac{1425\times \sin 47\textdegree}{\sin 74\textdegree}\\\\A=1084.18\ feet$

Hence, the distance from ship B to the submarine is 1270.68 feet and the distance from ship A to the submarine is 1084.18 feet.
