Elanso [62]

Answer:

$\frac{1}{6}$ × $\frac{1}{6}$ × $\frac{1}{6}$ $=\frac{1}{72}$

$\frac{1}{2}$ × $\frac{1}{2}$ × $\frac{1}{2} =\frac{2}{8}$

$\frac{4}{6}$ × $\frac{4}{6}$ × $\frac{4}{6} =$ $\frac{8}{27}$

$\frac{1}{6}$ × $\frac{1}{6}$ × $\frac{1}{6}$ $=\frac{1}{72}$

$\frac{8}{27}$

15. PLEASE HELP ME

Nana76 [90]

Surface Area=7238in^2

We know

$\boxed{\sf Surface\:area=4\pi r^2}$

$\\ \sf\longmapsto 4\pi r^2=7238$

$\\ \sf\longmapsto 4\times \dfrac{22}{7}r^2=7238$

$\\ \sf\longmapsto r^2=\dfrac{7238\times 7}{88}$

$\\ \sf\longmapsto r^2=\dfrac{5066}{88}$

$\\ \sf\longmapsto r^2=575.75$

$\\ \sf\longmapsto r^2\approx576$

$\\ \sf\longmapsto r\approx\sqrt{576}$

$\\ \sf\longmapsto r\approx24in$

PLEASE HELP!!!!!!<br>If g(x) = 2 − 1, what is g(−2.3)?<br> a.-7<br> b.-5<br> c.-4<br> d.-3

Andru [333]

Assuming there's an x after the 2 g(x)=2x-1 g(-2.3) is basically just putting -2.3 in the x which would be 2(-2.3)-1 which is:
-4.6-1 which is -5.6.
The final answer would be g(x)=-5.6
Hope this helps!

Which step in the construction of copying a line segment ensures that the new line segment has the same length as the original l

bogdanovich [222]

Here are the steps I think you probably will go through.
1. Draw a line that is longer than the segment but shorter than the width of the page.
1a. Make sure this line is at least 1/2 inch from the left hand side.
2. Use a compass to measure the length of the original segment. Never use a ruler. Rulers do not exist in pure geometry.
3. Measure out the distance on the line you just drew with the compass. One end is on the left hand edge and the other end (the pencil end) is marking the segment so it is the same length as the compass. You are done.

The key step either two or three.
