Answer:
36 minutes when both pipes are working together
Step-by-step explanation:
capacity of tank = 5400 liters
Pipe A flow per mint. = 5400/90 = 60 liters per mint.
Pipe B flow per mint. = 5400/60 = 90 liters per mint.
Flow of A + B per mint. 60 + 90 = 150 liter per mint.
Therefore, 5400 / 150 = 36 minutes to fill the tank
The 31.31% of the $54.6 Billion was spent.
for the percentage solution
x%=(amount spent on veterinary/ total amount) *100
Calculation:
let "x" be the percent of $54.6 billion spent on veterinary and total amount spent is $17.1 billion.
putting values in above formula
x%=(17.1/54.6)*100
x%=(0.3131)*100

k=1
= 3(4a^2 + 4a - 3) - 4a^2 + 28
= 12a^2 + 12a - 9 - 4a^2 + 28
= 8a^2 + 12a + 19
= 4a(2a + 3) + 19
