A children's liquid medicine contains 100 mg of the active ingredient in 5 mL . If a child should receive 150 mg of the active i
wariber [46]

Answer:

The correct answer is 7.5 ml

Explanation:

The medicine contains 100 mg in 5 ml, that means that the concentration of the active ingredient is 100 mg/5 ml= 20 mg/ml

If we divide a concentration (in mg/ml) into a mass (in mg) we obtaine a volume (in mL). Thus, in order to calculate the mililiters of medicine which contain 150 mg of the active, we have to only divide mass (150 mg) into the concentration of active ingredient as follows:

mL = \frac{150 mg}{20 mg/mL}= 7.5 mL

What is the acceleration of a marble in that has a mass of 90kg and a force applied of 60N
miskamm [114]

Answer:

0.6... or 3/5

Explanation:

To find the acceleration, we need to use the acceleration formula:

  • a=F/m

So all we have to do now is plug in the numbers:

  • a = 60/90

Once we divide 60 by 90, we will get the acceleration of the marble.

  • 60/90 = 0.6... (repeating)

Our final answer should be:

0.6... or 3/5
