Answer:

The answer would be 175

Step-by-step explanation:

Step 1, Write the first four terms:

With the number 64, multiply it by 0.75, to get 48. Then multiply 48 by 0.75 again, to get 36. Then multiply 36 by 0.75 to get 27.

Step 2, add up the terms:

The first four terms are 64, 48, 36, and 27. Now just add them together!

64 + 48 + 36 + 27 = <u>175</u>

Answer:

Hi! I can't really see the graphs on the picture but i can tell you what it should looks like, The graph opens up which means it makes a U shape and The vertex is (- \frac{9}{4}, -\frac{185}{4}) the Axis of Symmetry is x = -\frac{9}{4}and, if you can find all those points in your graph then you'll get 100% i'm sorry that i can't see the picture but i can see the shape but i also need to see the Units.

In need of geometry help, once again my stupid brain cant remember anything.
melomori [17]

You cannot rely on the drawing alone to prove or disprove congruences. Instead, pull out the info about the sides and angles being congruent so we can make our decision.

The diagram shows that:

  • Side AB = Side XY (sides with one tick mark)
  • Side BC = Side YZ (sides with double tickmarks)
  • Angle C = Angle Z (similar angle markers)

We have two pairs of congruent sides, and we also have a pair of congruent angles. We can't use SAS because the angles are not between the congruent sides. Instead we have SSA which is not a valid congruence theorem (recall that ambiguity is possible for SSA). The triangles may be congruent, or they may not be, we would need more information.

---------------

So to answer the question if they are congruent, I would say "not enough info". If you must go with a yes/no answer, then I would say "no, they are not congruent" simply because we cannot say they are congruent. Again we would need more information.
