The answer is nearest integers
Ok, here's a trick: If you're converting a smaller unit to a bigger unit in metric system, you divide by 10. When you are trying to convert a bigger unit to a smaller unit, multiply by 10. Decimeters are 1/10 of a meter, so you are going to multiply 2 by 10 because you are converting a bigger unit to a smaller unit, in which you get 20.
So your answer is 20 decimeters.
Answer:
50 pounds = 22.7 kilograms
Step-by-step explanation:
Yes both are correct
Sabine :
2.2 pounds = 1 kilogram
1 pound = 1/ 2.2 kilogram = 0.454 kilogram
50 pounds = 50 * 0.454 =22.7 kilograms
Regardless of the sign of
, we have
(never negative). But multiplying by -1 makes it negative.
On the other hand,
which can never be negative for real
.
The answer is A) √3
cot(-5π/6)=1/tan(-5π/6)
=1/tan(-(5π/6)
Use the property: tan(-x)=-tan(x)
=1/tan(5π/6)
-(1/tan(5π/6))
tan(5π/6)=-√3/3
-(1/-√3/3)
-(1/-√3/3)
=√3
