Answer:
<h2>2/3 of a full rotation<u><em> is 240°.</em></u></h2>Step-by-step explanation:
A full rotations is doing spinning 360° around a fixed point which is called "center".
So, if a full rotation is 360°, how many degrees would be 2/3 of 360°?
To answer this question, we just need to multiply the fraction with the full rotation:
Therefore, 2/3 of a full rotation is 240°.

Answer:
19 days
Step-by-step explanation:
Given
--- initial
-- rate
Required
Days when the fish gets to 30
The function is exponential and as such it follows;
Where x represents the number of days and y the number of fishes
Because the fishes decreases;
So, we have:
Express as decimal
In
So, we have:
Divide both sides by 150
Take log of both sides
Apply law of logarithm
Make x the subject
<em>Hence, it takes approximately 19 days</em>
3x + 7 = x
First, subtract 3x from both sides. / Your problem should look like: 7 = x - 3x
Second, simplify x - 3x to -2x. / Your problem should look like: 7 = -2x
Third, divide both sides by -2. / Your problem should look like:
= x
Fourth, simplify to 
/ Your problem should look like: 
= x
Fifth, switch sides. / Your problem should look like: x =
