First we need to convert cm to mm
45 cm = 450 mm
Now our ratio looks like this
60/450
We can divide both by 30 and once we do that our ratio will look like this:
2/15
That means the answer is B
the answer is A, sorry if you can't read it quite well
Answer:
-4
Step-by-step explanation:
the highest f(x) value on the table is at -4 on the x column
6.40x+9.90(154-x)=1230.90
Solve for x
X=84 for child
154-84=70 for adults
