Answer:
A)2100 ml
Step-by-step explanation:
Given total vinegar is 3 1/2 liters and the used vinegar is 3/5 of the vinegar in the beaker:
#First calculate the amount of vinegar not poured in the beaker:

#Calculate amount of vinegar used in experiment:

#The unused vinegar is therefore calculated by subtracting the used vinegar from the total at the start of the experiment:

Hence, the unused vinegar is 2100 ml
Answer: yes they are the same
Answer:
(3√3 + 3√10)/3√5
Step-by-step explanation:
Radical means square root.
√3/5 + √2/45 = (3√3 + 3√10)/3√5
Note : √45 = √9 × 5 = √ 9 × √ 5 = 3√5
Answer:
20 mph
Step-by-step explanation:
time = distance / speed
speed up stream = s - 4
speed down stream = s + 4
time up = time down
8 / (s - 4) = 12 / (s + 4)
cross multiply
8s + 32 = 12s - 48
subtract 8v from both sides
32 = 4s - 48
add 48 to both sides
80 = 4s
Divide both sides by 4
20 = s
20mph
