Answer:

CD = 6.3

Step-by-step explanation:

The triangles CED and CGF are similar since two sides are on same line and one side is parallel.

<u>Corresponding sides have equal ratios:</u>

CG/CE = CF/CD
CG/CE = (CD - 1.8)/CD
6/(6 + 2.4) = (CD - 1.8)/CD
6/8.4 = (CD - 1.8)/CD
1/1.4 = (CD - 1.8)/CD
1*CD = 1.4CD - 1.4*1.8
0.4CD = 2.52
CD = 2.52/0.4
CD = 6.3

At a school pep rally the ratio of students who wore red to those who wore yellow is 7 to 3 their are 300 students at the rally

Serhud [2]

Red to yellow.......7:3....added = 10
so 7/10 of the total students wore red and 3/10 of the total students wore yellow

and there are 300 total students...
7/10(300) = 2100/10 = 210 wore red
3/10(300) = 900/10 = 90 wore yellow

how many more wore red.....(210 - 90) = 120 more students wore red then yellow
