Answer:

360cm³

Step-by-step explanation:

Consider the base to be the gray trapezoid.

V=S×h, where S is the trapezoid area and h=10cm is the prism height.

S=(b+B)d/2 where b and B are the bases, and d=6cm is the trapezoid height.

S=(8+4)×6/2=12×3=36cm²

V=S×h=36×10=360cm³

Answer:

The short answer is : x=6.81

Step-by-step explanation:

First thing to do is multiply in $\sqrt{2}$

<h3>To Until it become :</h3>

$5x {} ^{2} =164 * \sqrt {2}$

Now we will divided on 5 and calculate the numper to it equal 46.3

Then you will take square root To the two parties

To equal in the end =6.81

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.

a stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where s(t) = 4.9t^2 + 29.

Alenkinab [10]

Answer:

t = 9 s

Step-by-step explanation:

A stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where

$s(t) = -4.9t^2 + 29.4+132.3$

We need to find when the stone will hit the ground. It means when s(t) = 0. So,

$-4.9t^2 + 29.4t+132.3=0\\\\t=-3\ and\ t=9$

So, the stone will take 9 seconds to hit the ground. Hence, this is the required solution.
