Use a calculator to evaluate cot π/5.

1 answer:

7 0

Pi divided by five is roughly .63. I say "roughly" because pi is infinitely long so it's impossible to get an exact answer, but a common pi length would be <span>3.14159. </span>

I need some help with this math question

Vilka [71]

The answer is 63 cm bc 30 60 90 triangles have a rule where the short leg is x longer is x√3 and the hypotenuse is x2
you can see this if you imagine the triangle as equilateral then cutting it in half

Average Inventory at Cost: $18,127

alexandr402 [8]

Answer:

2.59

Step-by-step explanation:

Given that average inventory at cost = 18127/-

Cost of goods sold =46971

Hence stock turnover ratio at cost = cost of goods sold/average inventory

= 46971/18127 =2.59

(There is another method also to calculate stock inventory ratio

Stock inventory ratio = Retail sales/Average inventory at retail

=63410/24870

=2.5496

=2.55)

Since our question asks stock turnover at cost we get answer as

2.59

0.9 < -r plz help thank you

Komok [63]

0.9 will equal to $\frac{9}{10}$

Anyhow ! Lets get to the steps!

$\frac{9}{10} - r \leq ?$

$\frac{9}{10}$

Now "r" will become a negative

$\frac{9}{10} - - r \leq ?$

$\frac{-r(10)}{10}$

$\frac{10(r)+9}{10} \leq 0$

We have to multiply from each of your sides by the number 10

You can even divide by the number 10 aswell

Back to the steps

$r+ \frac{9}{10} \leq ?$

Subtract from this fraction $\frac{9}{10}$ to your sides

This would be inequality $r + .900 \leq ?$

$r \ \textless \ -\frac{9}{10}$ ← this should most likely be your answer

$Now, Good Luck$
