Plz help me now

n = 3 / 2, and n = 2; Option C

Step-by-step explanation:

We are given the following quadratic equation 2n^2 - 7n + 6 = 0, and must solve for the value of n;

2n^2 - 7n + 6 = 0 ⇒ Break this expression into groups,

( 2n^2 - 3n ) + ( - 4n + 6 ) = 0 ⇒ Factor n from 2n^2 - 3n,

n * ( 2n - 3 ) + ( - 4n + 6 ) = 0 ⇒ Factor - 2 from - 4n + 6,

n * ( 2n - 3 ) - 2 * ( 2n - 3 ) = 0 ⇒ Factor out common term 2n - 3,

( 2n - 3 )( n - 2 ) = 0 ⇒ Solve through the Zero Factor Principle,

2n - 3 = 0, and n - 2 = 0 ⇒ Solve for n,

Solution; n = 3 / 2, and n = 2

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
