15%=3
5%=1
5(20)=100
1(20)=20
So, there are 20 students in the class.
BE is parallel to CD, therefore, m∠BEC=m∠ECD, therefore mBC=mDE
BE is the diameter, so Arc BE is 180 degree
mBC+mCD+mDE=180
replace mCD with 3mBC, and replace mDE with mBC: mBC+3mBC+mBC=180
5mBC=180
mBC=180/5=36
mCD=3mBC=3*36=108
the inscirbed angle m∠ECD= the measure of arc DE=36
Answer:
The slope is

Answer:
174 packages of t-shirts PLEASE GIVE BRAINLIEST
Step-by-step explanation:
139 x 5 = 695 t-shirts are needed
695 ÷ 4 = 173.75
Since you have to purchase whole packages of t-shirts you will need to buy 174 packages of t-shirts. 174 x 4 = 696 t-shirts
174 packages
Each cousin will get 0.75 cents because you would have to divide $2.25 by 3. I hope this helps.
