We know that the 2 triangles are proportional and are similar so that means there must be a scale factor between the sides of the triangles. To find the D, we need to use the scale factor and multiply it by CD to find DE. The scale factor can be found by dividing 2 similar sides so: EF divided by DG is 5/1.25 which is 4. We can then multiply the scale factor which is 4 by CD so: 3.25 * 4 is 13. DE = 13

Anit [1.1K]

Answer:

2 games

Step-by-step explanation:

First, find how many that won this year by multiplying 24 by 3/4

24(3/4)

= 18

Find how many they won last year by multiplying 24 by 2/3

24(2/3)

= 16

Find the difference:

18 - 16

= 2

So, they won 2 more games this year than last year

A train goes at a constant speed. If it covers 150 miles in 2 1/2 hours What distance would it cover in 3 hours?
Hoochie [10]

Hi there!

In order to find your answer, you'll need to use the cross product method :

150 miles → 2 1/2 hours = 150 minutes

x miles     → 3 hours = 180 minutes

(150 × 180) ÷ 150 = x miles

27,000 ÷ 150 = x miles

180 = x miles


Your answer is: A train would cover 180 miles in 3 hours.


There you go! I really hope this helped, if there's anything just let me know! :)
