Cos60° = 0.5

Any angle less than 90° is an acute angle.

Therefore, 60° is the acute angle.

A container ship left port last week caring some good weighing a total of 125,890 tons today I stopped in another port to unload
11Alexandr11 [23.1K]

Answer:

Step-by-step explanation:

You need to be specific.  Did the weight decrease by 60 tons or 60 pounds?  I assume tons, but in math, you can't assume.

This problem seems overly simple, so I am wondering if some information is missing.  With the given information and assuming the decrease was in fact 60 tons, you would have:

125,890 - 60 = 125,830 tons

Octavia buys a pair of jeans for $20.50 plus 8% tax.
dezoksy [38]

Answer:

$56.70 all together

Step-by-step explanation:

$22.14 for the jeans

$34.56 for the jacket

$56.7 all together

Take your tax and move the decimal over to the left by 2 spaces

8. becomes .08

take .08 and multiply it by the price so

20.50 x .08= 1.64

and

32 x .08=2.56

the number you get is how much the tax is, $1.64 is 8% of $20.15

take that number and add it to your price

$1.64+$20.50= $22.14

Divide 1/2 and 3/4 and it can not be a mixed number.
mamaluj [8]

Answer:

Many options - 4/6 or 2/3 or 0.66

Step-by-step explanation:

When dividing fractions, we use KCF (keep, change, flip) so our new equation is 1/2 x 4/3. Just multiply! Your answer should be 4/6, and if it needs to be simplified, the answer is 2/3. The answer as a decimal is 0.66 !

Find cot theta. (-6,-3sqrt(5)
cupoosta [38]

0  Pretend that is theta XD


cot 0 = \frac{1}{tan0}


Find tan 0.

tan 0 = \frac{y}{x}

tan 0 = \frac{-3\sqrt{5}}{-6}

tan 0 = \frac{\sqrt{5}}{2}


cot 0 = \frac{1}{tan0}

cot 0 = \frac{1}{\frac{\sqrt{5} }{2} }    

Multiply 2/√5 to the numerator and the denominator (or multiply the reciprocal of the denominator to the top and bottom of the fraction)

cot 0 = \frac{1}{\frac{\sqrt{5}}{2} } (\frac{\frac{2}{\sqrt{5}} }{\frac{2}{\sqrt{5}}} )

cot 0 = \frac{2}{\sqrt{5}}  

Multiply √5 to the numerator and the denominator

cot 0 = \frac{2}{\sqrt{5}} (\frac{\sqrt{5} }{\sqrt{5} })

cot 0 = \frac{2\sqrt{5}}{5}
