To solve this problem, all we need is the conversion
factor.
We know that there are:
1 liter = 202.884 teaspoons
Therefore the mass of Phenobarbital is:
mass = (2 grams / 1 Liter) * (1 teaspoon) * (1 Liter /
202.884 teaspoons)
<span>mass = 0.00986 g = 9.86 x 10^-3 g = 9.86 mg</span>
The rate at which the sound travels in km/hr is 0.142km/hr
<h3>Conversion of m/s to km/hr</h3>
If a sound wave travels with a speed of 5120m/s, in order to convert to km/he, we will use the conversion factor below;
1hr = 3600secs
1km = 1000m
Using the conversion factor in our dimensional analysis
5120m/s = 5120m/1s * 1km/1000m * 3600s/1hr
5120m/s = 5120m/3600000
5120m/s = 0.142km/hr
Hence the rate at which the sound travels in km/hr is 0.142km/hr

Answer:
To find angle y you subtract the two angles form 180 degrees because it is a straight line. Then you subtract angle y and 72 from 180 because a triangle adds up to 180 degrees and you get angle x.
Hope this helps, ask if you have any more questions!
Y=6. you would replace x with 7 in the equation.
6(7) = 7y
42=7y
6=y
Answer:
Willy Wonka
Step-by-step explanation:
Given data
it takes Charlie 45 minutes walking at 2.5 km/hr
speed = distance /time
distance= speed*time
distance= 2.5*45
distance= 112.5 km
it takes Willy Wonka 15 minutes walking at 3.5 km/hr
distance= speed*time
distance= 3.5*15
distance= 52.5 km
Hence Willy Wonka stays closer
