Answer:
R=i
Step-by-step explanation:
R=i×100÷p×t
r=30105×100÷6570×12
r=3010500÷78840
r=38.18
Answer:
x = -4
Step-by-step explanation:
3(2x+8)=0
Divide each side by 3
3/3(2x+8)=0/3
2x+8 = 0
Subtract 8 from each side
2x+8-8=0-8
2x = -8
Divide by 2
2x/2 = -8/2
x = -4
Answer:
5.9
Step-by-step explanation:
tan30 = DB/14
DB = 14tan30
tan45 = AB/14
AB = 14tan45
AD = AB-DB =14tan45 -14tan40 = 5.91709
Answer:
scale factor = 
Step-by-step explanation:
Compare the ratio of corresponding sides, image to original.
AB = 6 units and A'B' = 2 units, thus
scale factor =
=
=
