Step-by-step explanation:
An aquarium tank can hold V liters of water.
The first pipe alone can fill the tank in minutes. Then the first pipe fills liters per minute.
The second pipe can fill the tank in minutes by itself. Then the first pipe fills liters per minute.
When both pipes are working together, they fill
liters per minute.
Working together they need
minutes to fill the aquarium.
Just substitute given times to find the common time needed.
Answer:
Number of cups of dough needed = 15 cups
Step-by-step explanation:
Cup of dough needed for each dumpling = 4/5 cup of dough
Total dumplings = 12
how many cups of dough does Aubrey need to make 12 dumplings?
Number of cups of dough needed = Total dumplings / Cup of dough needed for each dumpling
= 12 ÷ 4/5
= 12 × 5/4
= 60/4
= 15
Number of cups of dough needed = 15 cups
we can write "m more than t" like this:
V=hpir^2
we want 3/4 of volume so multiply the volume by 3/4 later
height=10
radius=4
v= 10pi4^2
v=10pi16
v=160pi
3/4 of 160pi=120pi cubic inches of water
aprox 377 cubic inches of water
