Answer:
They cost 730 all together.
Step-by-step explanation:
One the surface area of the hall is 310m^2.
so, 310 divided by 25 is 12.4, which means they need 13 tin of paint.
The cost for it is 13*10 which is 130.
For the area of the floor, it is 40*15, which is 600m^2.
Which costs 600.
So, 600+130=730.
Ok, well a square is basically two triangles, right? the 45 degree right triangle. if you consider the rules for a 45 degree right triangle, you get: x, x, 2sqrt(x)
plugging in 8, you get the diagonal to be 2sqrt(8) or 4sqrt(2)
29 + (-37) = 29 - 37
answer is C. 29 - 37
The answer is A, you divide the amount of girls by the amount of boys, so 14/2 is the equivalent of 7:1!! Hope this helps!!
