Answer:
i dont know the answer but can you help me
Step-by-step explanation:
<span>To find out how much wax is needed for the candles we need to figure out the volume of each candle. We know radius r=0.5 inches and height h=3 inches of the smallest candle and we know that the middle candle has r2=2r=1 inch and h2=2h=6 inches and the biggest candle has r3=3r=1.5 inches and h3=3h=9 inches. So now we need the formula for volume: V=pi*r^2*h and we simply plug in the numbers. First candle is V=3.14*(0.5^2)*3=2.355 inches^3. Middle candle: V2=3.14*(1^2)*6=18.84 inches^3. Biggest candle: V3=3.14*(1.5^2)*9=63.585 inches^3. So overall wax needed to create all three candles is V+V2+V3=2.355 inches^3 + 18.84 inches^3 + 63.585 inches^3=84.78 inches^3.</span>
Answer:
1/2 of the figure is shared
Step-by-step explanation:
From the attachment, 4 out of the 8 squares are shaded
The center square which makes it the 9th is subdivided into 9 squares again.
The pattern of division continues indefinitely.
In every subdivision, 4 squares are shaded leaving the other 4 squares white while the 9th(center square) forms another subdivision.
Therefore, it can be concluded that 1/2 of the figure is shaded.
Answer: 
Step-by-step explanation:
Remember the point-slope equation which is 
where
is your <u>point</u> and 
is your <u>slope.</u>
<u />
Given that we substitute what you have:
Minus and minus give us positive:
Multiply slope into the parenthesis:
Calculate it:
Isolate the 
by subtracting 10 from both sides:
Your final equation is:
Hope this makes sense!
And here's the graph to prove that the line actually goes through the point
