Answer:
10 kg
Step-by-step explanation:
In 3% concentration of 20 kg of seawater, there will be
kg of salt.
So, if it is a 2% solution of seawater,
Then 2 kg salt will be there in 100 kg solution.
So, 0.6 kg salt will be there in
kg of solution.
So, to make a solution from 3% to 2% we have to add (30 - 20) = 10 kg of water with a 20 kg solution. (Answer)
An angle bisector is a line passing through the vertex of the angle that cuts the angle into two equal smaller angles.
If MN is angle bisector, then
m∠JMN=m∠NMK.
The two smaller angles are adjacent angles, then
m∠JMK=m∠JMN+m∠NMK=2m∠JMN.
Divide this equality by 2:

Answer:
B. Divide 124 by 229.
Step-by-step explanation:
Given the table

The <u>joint relative frequency</u> is the ratio of the frequency in a particular category and the total number of data values.
The total number of males 
The number of males that like drama 
So, to find the joint relative frequency of being male and attending a drama movie, you should divide 124 by 229.
An angle cannot be the complement of one angle and the supplement of another angle at the same time. Then the given statement is false.
<h3>What is an angle?</h3>
The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
An angle cannot be the complement of one angle and the supplement of another angle at the same time.
Then the given statement is false.
