Determine which postulate or theorem can be used to prove that<br> REM= DME.
Snowcat [4.5K]

Answer:

SSS

Step-by-step explanation:

REM and DME share a side. This side is of course congruent.

In addition, sides RM and ED are marked as congruent, as are RE and MD.

All three corresponding sides of each triangle are congruent, which proves the triangles' congruency.

No information is given about the angles in these triangles, so none of the other theorem answer choices are valid.

Please mark brainliest! :)

Dennis wants to save $189 for a trip to an amusement park. He sets aside $14 of his allowance at the end of each week. How many
Butoxors [25]

Answer:

x = 13.5 weeks

Step-by-step explanation:

Since he wants to save $189 in total, that will be on one side of the equation by itself. You have to set this up in a y = mx + b equation. The y will be the 189. Since the word "each" goes with the number 14, that will be your m value. There is no value for b.

189 = 14x is your equation. The only step after setting up the equation is to divide 189 by 14. This gives you 13.5. Dennis will have to save up for 13.5 weeks.

I am not sure what the set/sets are supposed to be...
Fudgin [204]

Answer:

  see the attachment

Step-by-step explanation:

(a) S1 is the set of all subsets of {t, u, v}. There are 2^3 = 8 subsets, the EMPTY set being one of them. They are listed in the attachment.

It seems likely your answer will need to match that shown in the attachment:

  {EMPTY, {t}, {u}, ... , {t, u, v}}

where the elements of multi-element sets are listed separately: {t, u}, not {tu}.

__

(b) S2 is the set S1 with <em>w</em> added to each subset. (see the attachment for a listing)

__

(c) Correct, the sets are disjoint, since every set in S1 is different from every set in S2.

__

(d) Each set has 8 elements; the sets are the same size. You know this because you created set S2 from set S1. (See (b), above.)

__

(e) The sets are disjoint (see (c)), so the total number of elements in their union is the total of the numbers of elements in each set: 8 + 8 = 16.

__

(f) P(A) is undefined here, so none of these questions can be answered.
