10 times 0.84 is 8.4 or 8.40 is completely fine as well.
Direct variation:-
y = kx where k is a constant
y=12 when x=6 so we have:-
12 = k*6
k = 12/6 = 2
so our equation of variation is y = 2x Answer
Answer:
c is the answer
Step-by-step explanation:
i ust know
Answer:
Well.. its already in standard form..
but even if u want u can write it as 8 X 10^(-1)
Step-by-step explanation:
Standard form is used for quite big decimal numbers
like : 0.2356
We can write it as 2.4 X 10^(-1)
Answer: y=0
Step-by-step explanation: i think this is right
