Answer:
(i think it is for q6 so) $6
Step-by-step explanation:
4.50÷3=1.50 (that's for 1 pound of fudge)
1.50×4=6
The answer to that is 800 hundred. Here is a saying 5 or more raise the score 4 or less give it a rest
its (a) because (a) is C(x)=3x4+30x and 9+21 is 30 so its 3x2+30
Answer:
Katie height =1.73 m
George height =7 cm
formula
1 meter =100 cm 7/100 =0.007m
so George height =0.007 m
height of George = Katie height - George height
= 1.73 - 0.007 m
- = 1.723 m
- Height of George = 1.723 m

Answer:
Step-by-step explanation:
z=xi+yj
x=-1.2=r cosθ (say)
y=-1.6=r sinθ(say)
square and add
r²cos²θ+r² sin ² θ=(-1.2)²+(-1.6)²=1.44+2.56=4
r²=4
r=2
divide
tanθ=y/x=-1.6/(-1.2)=16/12=4/3
θ=tan ^{-1}(4/3)≈53.13°
so polar coordinates are (2,53.13°)
