Answer:

8 jars

Step-by-step explanation:

Let the number of jars is x.

80 liters distributed, each jar has:

80/x

Redistribution with 4 less jars, each jar now has:

80/(x - 4)

Each jar has now twice the amount:

80/x*2 = 80/(x - 4)
2/x = 1/(x - 4)
2(x - 4) = x
2x - 8 = x
x = 8

She prepared 8 jars at the start

Triangle congruence and similarly (picture included) SAS, ASA, SSS, or AAS?

N76 [4]

Answer:

SAS

Step-by-step explanation:

SAS Postulate: "If two sets of corresponding sides on two triangles and there included angle are congruent, then the triangles are similar".

We see that line segments XY-ST and XZ-SR are congruent along with the included angles X and S. Therefore, we can justify that SAS fits the situation.

15. Mark Twain one observed that the lower Mississippi River is very crooked and that over the years, as the bends and turns str

MrMuchimi

Answer:

Step-by-step explanation:

I'm sure he was making a joke at the expense of people who rely on mathematics rather than common sense. It is funny, but then Twain was a remarkably funny author..

The problem is that the comparison is apt using some sort of proportion, but it is absurd to think that the land holding the river would also shrink a proportional amount.

The river reached a minimum (presumably) in 1875 by cutting out all the loops that were there in 1700. The Mississippi was then a straight line from it's beginning to its delta on the gulf of Mexico. It could not get any shorter. Still, Twain managed to get laughs with his whimsical humor.

Thanks for posting. This made my evening.
