The sweater prices have reduced by 80% due to the special.
Step-by-step explanation:
Step 1; Cost before reduction was $30. The cost after reduction was 6$. Cost reduced= cost before reduction - cost after reduction
Cost reduced= $30 - $6 = $24
Step 2; We must find how much of the cost was reduced from the initial cost i.e. how much $6 is to $30. To do this we must convert it into a percentage. We divide the $6 with the $30 to get a value. This value must be multiplied with a 100 to be converted into a percentage.
Cost by which sweater was reduced= 24/30 * 100 = 0.8 * 100 = 80%.
So the price of the sweater was reduced from $30 to $6 which means there was a reduction of 80%.

Answer:
C and E
Step-by-step explanation:
Recall that according to the complex conjugate theorem, if P(x) is a polynomial function with real coefficients, and a+bi is an imaginary root of P(x), then its conjugate (i.e a-bi) must also be a root.
Here we see that 2 of the given roots are imaginary : i and 2+i
by the theorem given above, the conjugates of these must also be roots
i.e -i and 2-i
To find the speed of the boats we will divide the distance by time.
From the graph we finde the boats' speeds as ;
And for the speed of the third boat, we will also divide the distance by time.
As you can see the speed of boat 3 (8 km/h) is more than boat 1 (7 km/h) and boat 2 (5 km/h).
Thus the third boat is faster than both of them.
The answer is B.
You can see the speed of boat 1 and 2 in the picture.
If you have a rombus for example lets say the obtuse is 180 and the acute is 30 so the opposite angel of both is what the other is if that makes any sence
