What is the scale factor of UVW to XYZ?

Answer:

<h2>The scale factor is 7.</h2>

Step-by-step explanation:

In the image attached, you can observe that both triangles are similar, and we can establish the following proportionality

\frac{UW}{XZ}=\frac{UV}{XY}=\frac{WV}{ZY}

Replacing the length of each side, we have

\frac{2}{14}=\frac{3}{21}=\frac{4}{28}\\\frac{1}{7}= \frac{1}{7}=\frac{1}{7}\\7=7=7

Therefore, the scale factor between these triangles is 7, that is, ΔXYZ is seven times bigger than ΔUVW

XZ ~ UW
UV ~ XY
VW ~ YZ

Take any corresponding side and the ratio of it is your answer. 

Example : 

XZ / UW = 14/ 2 = 7
XY / UV = 21 / 3 = 7
YZ / VW = 28 / 4 = 7 

Therefore, your answer is B. 7

3. A bag contains 46 blue ballons, 30 red ballons, and 24 purple ballons.
zalisa [80]
A because all of the numbers add up to 100 and there is 30 red so that would make it 30/100 and simplified it would be 3/10

The distance between Joshua's home and school is 800 m. Joshua takes 5 min to walk
Fynjy0 [20]

Answer:

= 0.38 m/s

Step-by-step explanation:

▪Total distance = 800 m

5 min = 100 m

▪Remaining distance = 800 - 100 = 700 m

20 min = 700 m

▪Total time taken = 20 + 10 + 5 = 35 min

If 1 min = 60 sec

What about 35 min = ?

= 35 x 60

= 2100 sec

▪Average speed = TD ÷ TT

= 800 ÷ 2100

= 0.38 m/s
