Calculs from the north you walk 1 mile and a temperature was 5 degrees from the west you walk 1 mile and the temperature change
MakcuM [25]

Answer: 6.4 degrees

Step-by-step explanation:

a= 5 degrees temperature difference to the north gives the opposite of the triangle,

b = 4 degrees temperature difference to the west gives the adjacent,

c = temperature difference of 1 mile to the south east gives the hypotenuse.

Therefore,

Using Pythagoras equation,

c² = b² + a²

c = sqrt( 5² + 4²)

c = sqrt(41) = 6.4 degrees

Therefore, there will be 6.4 degrees temperature difference 1 mile to the south east

If equipment cost $20,000 and accumulated depreciation amounts to $6,000, the book value of the equipment is?
Rina8888 [55]

The book value of the equipment is $14000

Given,

equipment cost = $20,000

depreciation amounts =  $6,000

book value of the equipment = equipment cost - depreciation cost

= 20000 - 6000

= $14000

<h3>What Are Depreciation Expenses?</h3>

Depreciation expense, on the other hand, is the amortized portion of the cost of the business's fixed assets during a certain period. Depreciation expense is recognized in the income statement as a non-cash expense that reduces the  net income or profit of the business. For accounting purposes, depreciation expense is debited and  accumulated depreciation is credited.

Depreciation expenses are treated as non-cash expenses because periodic monthly amortization is  not involved in cash transactions.

If cos A = 3 over 11, then which of the following is correct?
ziro4ka [17]

Answer:  The answer is (a) sec A = 11 over 3.



Step-by-step explanation: Given that Cosine of an angle 'A' is 3 over 11,

i.e.,

\cos A=\dfrac{3}{11}.

And we need to find which one of the given four options is correct.

We have the following relations between cosine, secant and cosecant of an angle from trigonometry.

\sec A=\dfrac{1}{\cos A}~~\textup{and}~~\csc A=\dfrac{1}{\sqrt{1-\cos^2 A}}.

Therefore,

\sec A=\dfrac{11}{3}

and

\csc A=\dfrac{1}{\sqrt{1-\frac{9}{121}}}=\dfrac{1}{\sqrt{\frac{112}{121}}}=\dfrac{11}{4\sqrt 7}.

Thus, the correct option is (a)  sec A = 11 over 3.
