To get 20% of something, you must divide it by 5 since 20*5=100
Anyway, since Jada's dog is 20% of it's adult weight, but currently weighing 9kg, we must multiply that by 5
9*5=45kg
Jada's dog's adult weight is 45kg
Hope it helped
Answer:
B(7,10)
Step-by-step explanation:

Hello,
9)
∠DBC=90-54=36°
∠CAD=∠DBC=36°
10)
∠BOC=1/2(360-2*100)=1/2*160=80°
∠l=1/2∠AOD=1/2∠BOC=40°
11)
JL=10
JA=7==>AL=10-7=3
LC=AL=3
LK=11
CK=11-3=8
KB=KC=8
BJ=JA=7
perimeter=10+11+15=36
C + t = 75......c = 75 - t
6c + 3t = 312
6(75 - t) + 3t = 312
450 - 6t + 3t = 312
-6t + 3t = 312 - 450
-3t = - 138
t = -138/-3
t = 46 <=== 46 cups of tea were sold
c = 75 - t
c = 75 - 46
c = 29 <=== 29 cups of coffee
