The formula is V=Bh You'd get the base (it's a circle so you'd have to do A=pie*radius square) Once you find the base, you mutliply it by the height

Pls help for 27b!!!!!!!

rodikova [14]

Step-by-step explanation:

$\beta$

is a root of the quadratic

$4 {x}^{2} - 10x + 5$

This quadratic isn't factorable so use the quadratic formula

$- b + - \sqrt{ \frac{b {}^{2} - 4ac }{2a} }$

The plus and minus sign after b means we going to have two roots.

The roots are

$\frac{5 + \sqrt{5} }{4}$

and

$\frac{5 - \sqrt{5} }{4}$

We subsitue those values for Beta.

27a.

$\frac{5}{2}$

27b.

elaine's mother is now 38 years old. seven years from now she will be five times as old as elaine will be then. write and solve

vfiekz [6]

In seven years her mother will be 38 +7 = 45 years old.

She will be 5 times as old, so divide 45 by 5: 45/5 = 9. Elaine will be 9 years old then, so she is 9-7 = 2 years old now.
