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:
<u>4 Objects can fit in the box</u>
Step-by-step explanation:
First, translate the box's 1-foot side into 12 inches. Now multiply all the box's sides together to get 12*3*4. This will equal 144 cubic inches. Now divide 144 by 36 to get 4.
1 -since everything includes 4a, we can factor that to get 4a(a-4b^3+2b^2c)
2 - since 5 and 3 add to 8 and multiply to 15, we can do (n+5)(n+3)
3 - since -5 and -4 add to -9 and multiply to 20, we can do (g-5)(g-4)
4 - since -10 and 3 add to -7 and multiply to 30, we can do (z-10)(z+3)
5 - we can factor out 4y to get 4y(y^2-9).
I got the numbers in 2, 3, and 4 with a guesstimating and checking approach
