Answer:
C
Step-by-step explanation:
So first, you find the area of a rectangle, which would be 15 * 30 = 450. Next, find the area of the semicircle by doing 
(you have to divide by 2 because it's only have a circle).
The radius is half of 15, so 15 / 2 = 7.5. This would be:
The last step is to add 450 + 88.3125 = about 538.3 m^2
Answer:
b
Step-by-step explanation:
An empty cubical carton of side 7cm has the volume:
7 x 7 x 7 = 343cm³
A cube of side 1cm has the volume:
1 x 1 x 1 = 1cm³
From this, we can see that a 1000 cubes of side 1cm has the volume:
1000 x 1cm³ = 1000cm³
But we know that the cubical carton of side 7cm only has a volume of 343cm³.
Since 1000cm³ > 343cm³,
you cant fill 1000 cubes of side 1cm in such a carton.
TL;DR
No

Answer:
1/15 of a kilogram
Step-by-step explanation:
,\left[x \right] = \left[ \frac{-2}{3}+\frac{\left( -4\right) \,y}{3}+\frac{z}{3}\right][x]=[3−2+3(−4)y+3z]
\left[X \right] = \left[ 5+6\,y - 2\,z\right][X]=[5+6y−2z]
\left[x \right] = \left[ 2+\frac{3\,y}{2}+\frac{ - z}{2}\right][x]=[2+23y+2−z]
system by elimination
