Step-by-step explanation:
Simplest form=10/30=1/3
=1cm:3cm
Simplest form=2cm:1m
1m=100cm
2:100
2/100=1/50
1cm:50cm
Answer:
c=sqrt21
Step-by-step explanation:
angle c is the angle between a and b, so use the cos law
c^2=a^2+b^2-2*a*b*cosC
c^2= 16+25-2*4*5*1/2
c^2=21
c=sqrt21
Answer:
-5/24
Step-by-step explanation:
Find a common denominator:
-7/12 times 2= -14/24
3/8 times 3= 9/24
-14/24 +9/24 =5/24
It is an enlargement because the scale factor is 2 and a half
