<span>The answer to the question asked above is as follows:
1 dozen = 12 pieces
3 dozen = (12 pieces)(3) = 36 pieces
thus :
If 3 dozen apples is $4.50 , each piece would be $4.50 / 36 pieces.
So $0.125 per piece of apple.

Answer:
f

1
(
x
)
= arccos (
x
)
+ π/
2
Step-by-step explanation:
y=cos(x-pi/2)
For inverse, interchange the variables and solve for y
f
−
1
(
x
)
= arccos (
x
)
+ π/
2
So, we know this:
<span> 5x+10y = 800
and we also know that the number of larger vehicles was 50.
So we can substitute:
</span>
<span>5x+10y = 800
</span>
<span>5x+10*50 = 800
and calculate:
</span><span>5x+500 = 800
and now subtract 500 from both sides:
5x=300
and divide by 5:
x=60.
and this is our answer: there were 60 smaller vehicles washed!
