I like A as the best one
420 = 100*price - (fixed costs)
220 = 60*price - (fixed costs)
If we subtract one from the other one, we get 200 = 40*price, price = 5
that said, fixed costs are 500 - 420 = 80
Now if we move -220 to the right in Answer A, we'll get:
y = 5x -300 + 220 = 5x - 80
So it looks like A describes the model best
* means multiply, sqrt=radical
expand
-10+sqrt2*8i-sqrt2*15+24i
group
(-10-sqrt2*15)+(sqrt2*8+24)i
not exactly sure though
Answer:
A. Weight and buoyancy :P Have a good day
Step-by-step explanation:
Answer:
2.5cm
Step-by-step explanation:
area of a trapeziod = 1/2 (a+b)×h
a=1cm
b=5cm
h=?
area= 7.5cm^2
••••• 7.5cm^2=1/2 (6)h
7.5= 3h
then height = 7.5/3= 2.5cm
X/50 = 20/100
its takes adding 30 to 20 to get to 50 so add 30 to 100 then its 130/100 (130 over 100) and then divide that and its 13 = 13%
i think its right dont hold it against me if im wrong
