A metallic spherical ball of radius 14 cm is being melted and recast it into spherical balls of radius 2 cm. How many spherical
mojhsa [17]

Volume of sphere = 4/3 x pi x r^3

Volume of large sphere:

4/3 x 3.14 x 14^3 = 11488.21 cubic cm

Volume of smaller sphere:

4/3 x 3.14 x 2^3 = 33.49 cubic cm

Number of small spheres = volume of large sphere/ volume of small sphere

11488.21 / 33.49 = 343.03

Round to 343 small spheres

Solve each quadratic equation by factoring with grouping. 5v2 – 18v = -9
djyliett [7]

Answer:

v = 3 , 3/5

Step-by-step explanation:

5 {v}^{2}  - 18v + 9 = 0 \\ 5 {v}^{2}  - 3v - 15v + 9 = 0 \\ v(5v - 3) - 3(5v - 3) = 0 \\ (5v - 3)(v - 3) = 0 \\ v = 3 \\ v =  \frac{3}{5}

The perimeter of parallelogram is 72 meters. The width of the parallelogram is 4 meters less than its length . Find the Length a
Marrrta [24]
Let n = length
let n-4 = width since it is 4 meters shorter

2( n+n-4)  =72  Two of the length and width added together equal the perimeter
combine like terms
2(2n -4) = 72   Now use the distributive law on the left side of the equation
4n -8 = 72    Now add 8 to both sides

4n -8 +8 = 72 +8
4n = 80  Finally divide each side by 4
n=20
so the length is 20 and the width is 4 less or 16.
Let's see if our answer works.
20 + 16 + 20 +16 =?  72
 72 =72  yes, it does.   Length = 20 Width = 16
