YES
Base=b
Height= h
Area 1=A1=1/2*b*h
Base=b
Height= 4h
Area of triangle 2=A2=1/2*b*4h
A2/A1= (1/2*b*4h)/(1/2*b*h)
= (1/2*b*4h)/(1/2*b*h)
=4/1
Ratio of heights =h2/h1= 4/1
Ratio of areas =A2/A1= 4/1
They are proportional.
Answer:
5:4 is the simplified ratio while the actual ratio is 30:24
Step-by-step explanation:
Answer:
L =80
w=60
Step-by-step explanation:
P =280
L =w +20
=>L +w=280 :2 =140
w+20+w=140
2w=140 - 20
2w =120
w=120 :2 =60
L=60 +20 =80
P =2L +2w
P =2 ×80 +2 ×60
P=160 +120
P=280
Answer:
-5<x<10
Step-by-step explanation:
1) -6< x-1<9
you take -1 out for both sides and it changes the sign
-6 +1< x< 9+1
-5<x<10
Good luck!
