Answer:
3.125 mg/ oz
Step-by-step explanation:
Amount of instant tea = 24 ounces
Amount of green tea = 12 ounces
Caffeine in instant tea = 24/8*30= 90 mg/oz
Also, caffeine in green tea = 12/8*15 =22.5 mg/oz.
Total amount of mixture= 24+12= 36 ounce
Total amount of caffeine in the mixture = 90+22.5 = 112.5 mg/oz
Caffeine per ounce in the final mixture = 112.5 / 36 = 3.125 mg/ oz
Answer:
Melinda will paint 5/8 part of a wall when Desiree has finished painting 1 wall.
Step-by-step explanation:
It is given that:
Melinda can paint 1/4 of a wall in the same time that Desiree can paint 2/5 of a wall.
Let 't' be the time taken by Melinda and Desiree to paint 1/4 and 2/5 of a wall respectively.
Now the time taken by Desiree to paint 1 wall will be:
2/5 of wall= t
1 wall= (5/2) t
Now in this time ( i.e. 5/2 t) the part of a wall painted by Melinda will be:
As Melinda takes-- t time to paint= 1/4 of a wall
5/2 t she will paint= (5/2)×(1/4) of a wall= (5/8) of a wall.
Hence Melinda will paint 5/8 part of a wall when Desiree has finished painting 1 wall.
