Answer:
10017
Step-by-step explanation:
10^(4)-\sqrt(121)+3^(3)+4^(0)
So, 3^3= 27
4^0=1
10^4=10,000
-square 121= -11
So now you got:
10,000-11+27+1
=10017
Answer:
x = 15/11
Step-by-step explanation:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
(x+3) *x = 2x*(6x-6)
Divide each side by x
x+3 = 2(6x-6)
Distribute
x+3 = 12x-12
Subtract x from each side
x+3-x = 12x-x-12
3 = 11x-12
Add 12 to each side
3+12 = 11x-12+12
15 = 11x
Divide each side by 11
15/11 =x

Answer:
£6/h
Step-by-step explanation:
Molly is paid £280 for 35 hours' work, so
£280/(35 h) = £8/h
In the next 5 hours, her pay jumps to £350, so she earns at a rate of ...
(£350 -280)/(5 h) = £70/(5 h) = £14/h
The difference in her pay rates is £14/h -£8/h = £6 per hour.
