The amount of money Sid would spend to make a carry-all bag for his wheelchair is $5.694.
<u>Given the following data:</u>
- Length of canvas material = 0.6 meter.
- Cost of canvas per meter = $9.49
To calculate the amount of money Sid would spend to make a carry-all bag for his wheelchair:
<h3>How to solve a word problem.</h3>
In this exercise, you're required to determine the total cost required to make a carry-all bag for Sid's wheelchair, if the canvas is $9.49 per meter and 0.6 meters of it is needed. Thus, we would multiply the cost of canvas by the length of canvas material that is required.
Mathematically, this is given by this expression:
Total cost = $5.694.

Hope this helps. Good luck! :)
For this case we can make the following rule of three:
1 square mile -------------------> 4.6 * 10 ^ 4 pieces of trash
1.2 * 10 ^ 8 square miles -------> x
From here, we clear the value of x:
We have then:
x = (1.2 * 10 ^ 8) * (4.6 * 10 ^ 4)
x = 5.52 * 10 ^ 12 pieces of trash
Answer:
there are 5.52 * 10 ^ 12 pieces of trash in the earth's oceans
6/11y=-18/22
Least Common Denominator is 11: 6/11y=-9/11
Multiply both sides by 11: 6y=-9
Divide both sides by 6: y=-9/6
Simplify: y= -3/2 OR -1.5
<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>
