Answer:
Earth?
Step-by-step explanation:
The answer is D) 0.36. The most preferred gum flavor is spearmint, which had 90 votes, and the total amount of students surveyed is 250. Then, do 90/250, which is 0.36 to find the answer. Hope this helps. By the way, took the test and got it right.
The point of intersection would be (3, 7)
Step-by-step explanation:
Let the smaller number be x
Greater number = 3x + 15
3x + 15 + x = 63
4x + 15 = 63
4x = 63 - 15
4x = 48
x = 48/4
x = 12
Greater number = 3(12) + 15 = 51
Answer:
Elevation in boiling point is mathematically expressed as
ΔTb = Kb X m
where Kb = boiling point elevation constant = 2.53°c/m (for benzene)
m = molality of solution = 3.47 m (given)
∴ ΔTb = 2.53 X 3.47
= 8.779 oC
But, boiling point of benzene = 80.1 oC
∴ Boiling point of solution = 88.879 oC
Now, Depression in freezing point = ΔTf = Kf X m
where, Kf = freezing point depression constant = 5.12°c/m (for benzene)
∴ ΔTf = 5.12 X 3.47
= 17.766 oC
But freezing point of benzene = 5.5 oC
∴ Freezing point of solution = -12.266 oC
