The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
Answer:

Step-by-step explanation:
We can use the point-slope formula given by:

The given line passes through the
point (-3,2) and having slope
.
We substitute the given point and slope to get:


we clear the fraction to get;




Or in standard form:

Answer:
a regular hexagon
Step-by-step explanation:
6 corners
The original statement is true!
the converse: If 2 lines do not intersect, they are parallel
the converse is false, the lines could be skew.
Hope this helped :)
