I believe the answer should be 102. It has been a long time since I have done one of these but I believe that if you times the outside angle by 2 then it is the angle if the point were to be in the center.

Find the volume of the garden shed
Leno4ka [110]

Answer:

47.3 m³

Step-by-step explanation:

The garden shed is made up of a rectangular prism and a pyramid.

<h3><u>Volume of a rectangular prism</u></h3>

\begin{aligned}\textsf{Volume of a rectangular prism}&=\sf width \times length \times height\\&=4 \times 4 \times 2\\&=16 \times 2\\&=32\;\; \sf m^3\end{aligned}

<h3><u>Volume of a pyramid</u></h3>

<u />

From inspection of the given diagram, the slant height of the pyramid is 3.5 m.  

Calculate the perpendicular height of the pyramid using Pythagoras Theorem:

\begin{aligned}\implies a^2+b^2&=c^2\\2^2+h^2&=3.5^2\\h^2&=8.25\\h&=\sqrt{8.25}\;\; \sf m\end{aligned}

Therefore:

\begin{aligned}\textsf{Volume of a pyramid}&=\dfrac{\sf length \times width \times height}{3}\\\\&=\dfrac{\sf 4 \times 4 \times \sqrt{8.25}}{3}\\\\& = 15.31883372\;\; \sf m^3\end{aligned}

<h3><u>Volume of the garden shed</u></h3>

\begin{aligned}\implies \textsf{Volume of shed}&=\textsf{Volume of rectangular prism}+\textsf{Volume of pyramid}\\&=32+15.31883372\\& = 47.3\;\; \sf m^3\;(nearest\;tenth)\end{aligned}

Fifteen more than half a number is 9
denis-greek [22]
Hey there!

"15 more than" will mean that 15 will be added to another term. The other term is "half a number", meaning 0.5x, where x is the number. This equation is equal to 9. The final equation is 0.5x + 15 = 9. 

To solve this, cancel out the terms until you find what x is equal to:

0.5x + 15 = 9 (subtract 15 from both sides)
0.5x = –6 (divide both sides by 0.5)
x = –12 (final answer)

Hope this helped you out! :-)
