315 dollars. u basically just multiply 10.50 with 30 hours s
i believe it's 22.5 out of 45 to get exactly .500
Answer:
Solution given;
l=4.5ft
b=2ft
h=2ft
now
volume=l*b*h=4.5*2*2=18ft³
is a required volume.
Now
total surface area =2(lb+lh+bh)
=2(4.5*2+4.5*2+2*2)=44ft²
is a total surface area.
Answer:
n = -5
I think the answer is -5, because:
The last number in the operation has a negative sign.
This can be a reason that it is-5.
Hope it helps!
