10% of 65
Of means multiply
=0.1 x 65
=6.5
Or you can use another way which is (part/whole) *(percent/100)
Whole=65
Percent=10
And part(part of 65)=unknown
(X/65)* (10/100)
Cross multiply
x= 6.5
So 10% of 65 is 6.5

The general equation of a quadratic function in factored form is equal to

where
a is a coefficient of the leading term
x_1 and x_2 are the roots
we have

substitute

Applying the distributive property convert to expanded form




therefore

Answer: 12 cm
Step-by-step explanation:
The masses of the spheres are proportional to their volums, and the cube of the ratio is k^3=135/5=27 ==> k=3
The greater radius is 3*4=12 (cm)
Regular shape with six sides: That is a Hexagon
Sum of angles in a regular Polygon is: (n - 2)*180
Where n = Number of sides
For Hexagon, n = 6.
Sum = (n - 2)*180
= (6 - 2)*180 = 4 * 180 = 720°
