Figure f is a scaled copy of Figure e.
Mekhanik [1.2K]

The correct equation of the scaled figure is given by 6/3 = 4/a

<h3>Scaling</h3>

Scaling is the process of either increasing or decreasing the size of a figure by a factor.

From the diagram attached, Figure f is a scaled copy of Figure e. Figure e is decreased to produce figure f, hence:

  • AB/XY = CD / WZ
  • 6/4 = 3 / a
  • 6/3 = 4/a

The correct equation of the scaled figure is given by 6/3 = 4/a

Helppppl pls I’m begging u
AlexFokin [52]

Answer:

4. James' hand

5. Salvador's plane traveled the furthest and Jennifer's plane traveled the shortest.

Step-by-step explanation:

4. James' hand is bigger because 0.17>0.165. You can add as many zeros to the end of each of them as you would like. You can think of this word problem as 0.170 versus 0.165. Or, if you needed to, you could pretend like they're whole numbers, and it would be 170 versus 165. Either way, 0.170 is going to be bigger than 0.165.

5. Salvador's plane traveled the furthest. Jennifer's plane traveled the shortest distance. All three numbers have a 3.3 in them. Now, it's a matter of who has the highest number in the blank after the 3.3: 3.3_. Because Jennifer's plane had a 0 in the blank, she traveled the shortest distance. 5 is bigger than 4.5, so Salvador's plane (the 3.35 one) traveled furthest.
