A A tent is in the shape of a triangular prism . How much material is needed to make the tent ?
MAVERICK [17]

Answer:

135

Step-by-step explanation:

Prism

volume= area of base times distance between your 2 bases

v=bh/2

i did  b=area of base, h=height , v=volume , 1/2...so i believe that you take 6 and multiply it by 5 which equals 30 then you multiply the 30 by 9 and i got 270 then i divide by 2... so 270/2 which equals 135..so the answer is 135

(for a rectangular shape its just length times height

one endpoint of AB has coordinates (-3,5) If the coordinates of the midpoint of AB are (2,-6),what is the length of AB?
avanturin [10]
We know that (-3,5) is the location of one of the endpoints.... and we know the midpoint is at (2,-6)... .now.. what's the distance between those two guys?

\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
&({{ -3}}\quad ,&{{ 5}})\quad 
%  (c,d)
&({{ 2}}\quad ,&{{ -6}})
\end{array}\qquad 
%  distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
d=\sqrt{[2-(-3)]^2+[-6-5]^2}\implies d=\sqrt{(2+3)^2+(-6-5)^2}
\\\\\\
d=\sqrt{5^2+(-11)^2}\implies d=\sqrt{25+121}\implies d=\sqrt{146}

so, the distance "d" from the midpoint to that endpoint is that much.  And the distance from the midpoint to the other endpoint is the same "d" distance, because the midpoint is half-way in between both endpoints.

so, the length of AB is twice that distance, or   \bf 2\sqrt{146}

13(10+2) could be used to simplify which of the following problems 130(26), 13(12), or 13(20)
svetoff [14.1K]
It could basically be used to simplify 130(26) because if you multiply the number on the outside of the parenthesis(13) with the numbers inside the parenthesis(10+2), you will get <span>130(26).</span>
