Answer:
64 times more paint will be needed since the volume of the second is 64 times the volume of the first
Step-by-step explanation:
If the original sphere is 12 cm diameter
its radius will be half this measure which is 12/2 = 6 cm
The new diameter is 4 times this, so its radius would be 4 times this and it is 24 cm
Now, the volume of the sphere means we have to raise the power of the radius by 3
The other terms in the formula remains the same for both, so we are simply comparing the radii
so we will have the difference in volume in times of multiples as ;
(24/6)^3 = 4 * 4 * 4 = 64
Answer: 7
Step-by-step explanation:
For L to be parallel to M, ( 7x + 9 ) must be equal to ( 8x + 2 ) because the two angles are corresponding to each other.
Equate both equation. That is,
7x + 9 = 8x + 2
Collect the like terms
7x - 8x = 2 - 9
- x = - 7
The minus sign will cancel out
X = 7
Therefore, the value of x that will make L||M is 7

Answer:
r = 12
Step-by-step explanation:
DG + GM = DM , substitute values
r + 3 + 4r - 28 = 35 , that is
5r - 25 = 35 ( add 25 to both sides )
5r = 60 ( divide both sides by 5 )
r = 12
Answer:
2=x
Step-by-step explanation:
8(4-x)=7x+2
Distribute
32 - 8x = 7x+2
Add 8x to each side
32 - 8x+8x = 7x+8x+2
32 = 15x+2
Subtract 2 from each side
32-2 = 15x+2-2
30 = 15x
Divide each side by 15
30/15 = 15x/15
2 =x
