What is the value of the ratio of the surface area to the volume of the right prism?

UkoKoshka [18]

So first fin the area then surface area and the volume
volume=legnth times width times heigh ttimes width=3 times 5 times 6=90
volume=90
surface area=(2 times 3 times 5)+(2 times 3 times 6)+(2 times 5 times 6)=(2 times 15)+(2 times 18)+(2 times 30)=30+36+60=126

volume=90
surface area=126
radio fo surface area to volume
90:126
simplify and treat as fraction
5:7
since they area all decimals they expect us to divide
5/7=.714
the closest answer is D, 0.7

the answer is D 0.7

Plz help I'll give brainy!!!

Answer:

see below

Step-by-step explanation:

we are given a exponential function

$\displaystyle y = \left(1/5\right) ^{x}$

we want to figure out the missing values of y for x i.e (-2,-1, and 2) to do we can consider substituting so,

when x is -2 y should be

$\displaystyle y = \left(1/5\right) ^{ - 2}$

rewrite ⅕ in exponent notation:

$\displaystyle y = \left((5) ^{ - 1} \right) ^{ - 2}$

by law of exponent we obtain:

$\displaystyle y = (5) ^{ 2}$

simplify square:

$\displaystyle y = \boxed{ 25}$

when x is -1:

$\displaystyle y = \left(1/5\right) ^{ - 1}$

rewrite ⅕ in exponent notation:

$\displaystyle y = \left((5) ^{ - 1} \right) ^{ - 1}$

use law of exponent which yields:

$\displaystyle y = \boxed5$

when x is 3:

$\displaystyle y = \left(1/5\right) ^{ 3}$

by law of exponent we obtain:

$\displaystyle y = 1/ {5}^{3}$

simplify square which yields:

$\displaystyle y = \frac{1}{ \boxed{125}}$

What are the exact solutions of x2 - 3x - 5 = 0? x = the quantity of negative 3 plus or minus the square root of 29 all over 2 x

Vinil7 [7]

$x^{2}-3x-5=0 \\ \\ \Delta=(-3)^{2}-4*1*(-5)=9+20=29 \\ \\ \sqrt{\Delta} = \sqrt{29} \\ \\ x_{1}= \frac{3- \sqrt{29} }{2} \\ \\ x_{2}= \frac{3+ \sqrt{29} }{2}$
