Answer:
Step-by-step explanation:
Basically it’s goin to be 50 because it says round to the ten and it’s basically 47
Answer:
Yes, the constant of proportionality is 1.5
Step-by-step explanation:
8 and 4 equals 32
3 and 4 equal 12.......
S= 1
J= 5
80(1) + 40(5) =280
(80 + 200)
Yvaires directly as x means
y=kx
y varies inversly with z means
y=k/z
therfor
y=(kx^2)/z
k=constant of variation
6=(k9^2)/27
6=(k81)/27
6=3k
divide both sides by 3
2=k
the constant of variation is 2
