3^3 + 2^7
Step-by-step explanation:
There really is no other way that I can think of other than guessing and checking. 3^3 is 27, when subtracted from 155 gives you 128. 128 can be rewritten as 2^7, leaving your final answer as 3^3 +2^7.

Answer:
I believe the world population should be 6,700,000,000
Ending Population = Beginning Population * (1 + rate)^years
Ending Population = 6,700,000,000 * (1.19)^40
Ending Population = 7,046,172,293,951
or rounded about 7,046,000,000
(About 7.046 billion)

Answer:
$299
Step-by-step explanation:
Given that 70% is $230 you can divide this by 7 to get 10%.
10% is 23. The remaining percentage we need is 30.
Soo 10% x 3 = 30%. (23x3)
23 x 3 = 69.
69 + 230 = $299

Answer:
- Translate P to E; rotate ∆PQR about E until Q is coincident with F; reflect ∆PQR across EF
- Reflect ∆PQR across line PR; translate R to G; rotate ∆PQR about G until P is coincident with E
Step-by-step explanation:
The orientations of the triangles are opposite, so a reflection is involved. The various segments are not at right angles to each other, so a rotation other than some multiple of 90° is involved. A translation is needed in order to align the vertices on top of one another.
The rotation is more easily defined if one of the ∆PQR vertices is already on top of its corresponding ∆EFG vertex, so that translation should precede the rotation. The reflection can come anywhere in the sequence.

<em>Additional comment</em>
The mapping can be done in two transformations: translate a ∆PQR vertex to its corresponding ∆EFG point; reflect across the line that bisects the angle made at that vertex by corresponding sides.
