Step-by-step explanation:
Cosine Ratio is the best tool to solve this problem.
cos38°=x/8
x =8*cos38°
x = 8*0.79
x = 6.32
The answer should be 2/3 divided by 1/8 gallons, plus 2/3
17.3 percent or approximately 18 people
The answer is <u>-8/3 pounds</u>. I just took the test.
Answer:
We know that the formula to mix chemical solutions is: C1V1 = C2V2
where C represents the concentration of the solute, and V represents volume in milliliters or ml.
In this case, we have:
0.06V1 = 0.15×350
Solving for 'V1' we have:
V1 = (0.15×350)/0.06 = 52.5/0.06 = 875
Therefre I can make 875 mL of a 6% solution by diluting 350 mL of a 15% solution.
