1.2mL will be needed to make 50 mL of a 2% solution
<h3>Ratio and proportions</h3>
Ratio are written in form of fractions.
If 50mL is required for a 2% solution, hence;
50% = 2mL
0.05 = 2mL
In order to determine the required mL for a 30% solution, we will have;
30% =x
0.03 = x
Find the ratios
0.5/0.3 = 2/x
Cross multiply
0.5x = 2(0.03)
0.5x = 0.6
x = 0.6/0.5
x = 1.2mL
Therefore 1.2mL will be needed to make 50 mL of a 2% solution

Answer:
m<−18
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
m+12<−6
Step 2: Subtract 12 from both sides.
m+12−12<−6−12
m<−18
Answer:
=12x+y
Step-by-step explanation:
Combine like terms
=5x+-3y+7x+4y
=(5x+7x)+(-3y+4y)
=12x+y
Answer: 5 feet and 7 inches
Step-by-step explanation:
"Give yourself 100 pounds for the first 5 feet plus 5 pounds for every inch over 5 feet tall"
100 pounds for 5 feet + 5 pounds/inch [over 5 feet]
We can separate 135 pounds into two parts: the first 100 pounds and the other 35 pounds: 135 = 100 + 35
100 = 5 feet
35 pounds/5 pounds/inch = 7 inches
So, the height is 5 feet and 7 inches
