Answer:
13.79%
Step-by-step explanation:
A solution is made by dissolving 24 millimeters of saline in 150 millimeters of pure solution
Therefore percent of saline in the pure solution can be calculated as follows
= 24/24+150 × 100
= 24/174 ×100
= 0.1379 ×100
= 13.79%
Hence the percent of saline in the pure solution is 13.79%
Answer:
81pi mm^2
Step-by-step explanation:
The radius is 1/2 the diameter, and is used in finding the area of a circle.
The formula for this is
A = pi(r)^2
So the formula you would use is
A = pi (9)^2
= 81pi
Usually teachers accept it in terms of pi, but if not, you can use 3.14 and multiple it.

Answer:
r = -3
Step-by-step explanation:
- 60= - 24 + 12r
Add 24 to each side
- 60+24= - 24+24 + 12r
-36 = 12r
Divide each side by 12
-36/12 = 12r/12
-3 =r
