Answer:
25 milliliters
Step-by-step explanation:
Given:
volume of sample = 100 ml
Syrup present in sample = 6.55 g per 20 mL
Therefore in 100 mL, amount of syrup present =
or
amount of syrup present in 100 mL sample = 32.75 grams
Now,
Specific gravity of the syrup = 1.31
also,
Specific gravity of the syrup =
or
1.31 =
or
Density of syrup = 1.31 g/mL
also,
Density =
therefore,
1.31 =
or
Volume of syrup in the sample =
or
Volume of syrup in the sample = 25 milliliters
Answer:
11th floor
Step-by-step explanation:
So to figure out what floor Rosa's office is in, we need to declare some variables.
x = Rosa's office
down 5 floors = -5
up 8 floors = 8
down 13 floors = - 13
One major clue to find Rosa's office is that she went down 13 floors to get to the 1st floor. So let's declare that Rosa is on the first floor.
x - 5 + 8 - 13 = 1
x - 10 = 1
x = 1 + 10
x = 11
So Rosa's office is at the 11th floor of the building.
Answer:
0.85% probability that the first two are good and the last three are spoiled
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the first two jugs is not important, as is not the order in which the last three are selected. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

Desired outcomes:
2 spoiled, from a set of 43-11 = 32.
3 spoiled, from a set of 11.
So

Total outcomes:
5 jugs from a set of 43.

Probability:

0.85% probability that the first two are good and the last three are spoiled
