Answer:
Cost of tshirt = £7.29
Cost of what = £0.86
Step-by-step explanation:
2t +3h = 12; 10t + 15h = 60
5t + 4h =33; 10t + 8h = 66
15h -8h = -6
7h = -6; h = -6/7; h = 0.86
2t +3(-6/7) =12
14t -18 = 84
14t = 102; t = 102/ 14; t=7.29
For x, the answer is x >= -(3 - y)/2, for y it's y <= 2x -3.
The surface area of a sphere is given by
We deduce
So, in your case, the radius is
The volume of a sphere is given by
So, we have
B.likely as probability is 5/6 which is very close to 1
