Which is more 0.02 or 0.1 ?

Answers

0.1 is the same as 0.10. If you forget the decimal it is 02 and 10 which is the same as 2 and 10. 10 is bigger than 2 so the answer is 0.1

.1 because if you change .1 to = .02 it is .10 and .10 is bigger than .2

In right triangle ABC, where C is the right angle : b = 12 and B = 33°. Find A, a, and c to the nearest tenth.

Answers

Answer:

A= 57° , a= 7.79 and c = 14.30

Step-by-step explanation:

In a given right triangle,

We have, b =12 ,B =33° and C =90°

We can find Angle A.

Angle sum property of triangle:

i.e A + B + C = 180°

A + 33° + 90° = 180°

A = 57°

Next, by using trigonometry

tanB = Perpendicular /Base = a /b

Here B =33° , a = ? , b = 12

So, tan 33° = a/12

0.6494 = a/12

a = 7.79

So we got a and b. By using Pythagoras theorem we determine c.

c^2 = a^2 + b^2

c^2 = 7.79^2 + 12^2

c = √(2046841) = 14.30

If a coin rotates 160 degrees in 6 seconds,how many degrees does it rotate in 20 seconds?

Answers

Okay so this is how I would do it but you can do it a different way
160/2 = 80 (2 b/c I want a whole # and 2 is a factor of 6 & 20)
so 80 degree in 2 seconds
so then 80 *10=800 (10 b/c 20/2=10)
but since there's only 360 degrees in a full circle
800/360=2.22
so we go back to 80 *2.22=177.6 degrees
-----------------------------------------------------------------------
v.s. 160 n
---- * --- (20 *160=3200/6=533.33
6 20

You can go w/ whatever answer you think is right b/c frankly I don't know but if I were you I would go with the second one because it seems more right and there's actually a method to the madness.

800g : 2kg
pls tell me

Answers

Answer:

2:5

Step-by-step explanation:

The ratio can be found by turning both values into either grams or kilograms. For this, I will make them both into grams.

1. 800g is already in grams, so leave it.

2. 2kg is in kilograms, and 1 kilogram = 1000 grams.

3. 2 kilograms is equal to 2000 grams.

4. For this reason, 800g: 2000g can be simplified by making 800g into 2, and 200g into 5.

That is the ratio, 2:5
