Step-by-step explanation:

${9}^{ \frac{ - 1}{2} } \\ {3}^{2 \times - \frac{1}{2} } \\ {3}^{ - 1} \\ \frac{1}{3}$

Now for another

${27}^{ \frac{ - 2}{3} } \\ {3}^{3 \times \frac{ - 2}{3} } \\ {3}^{ - 2} \\ \frac{1}{9}$

Hope it will help :)❤

Radius of a sphere that has a surface area 12.56in2 use 3.14

enot [183]

$\bf \textit{surface area of a sphere}\\\\
A=4\pi r^2\qquad 
\begin{cases}
r=radius\\
-----\\
A=12.56
\end{cases}\implies 12.56=4\pi r^2
\\\\\\
\cfrac{12.56}{4\pi }=r^2\implies \sqrt{\cfrac{12.56}{4\pi }}=r$

Answer:

A=115.6

Step-by-step explanation:

Hey There!

So the first step is to find the formula for area of a trapezoid

$A = \frac{1}{2} h(b1 +b2)$

h = height

b1 = base 1

b2 = base 2

now all we do its plug in the values

$A=\frac{1}{2} 6.8(28.3+5.7)$

$6.8x26.3=192.44\\5.7x6.8=38.76\\38.76+192.44=231.2\\\frac{231.2}{2} =115.6\\A=115.6$

Hope this helps!!

D - 8 divided by 5 = -4 d =

elena55 [62]

D = 0.32

d - 8 / 5 = -4d

d - 1.6 = -4d
d + 4d = 1.6
5d = 1.6
d = 0.32

This is an exact question in my math textbook. It should be correct.
