Since you can only obtain exactly $10 if you have an even amount of quarters you will need to plot 2x + y. With 'x' being the quarters and 'y' being the dimes.
Original position of the submarine below the Surface = -2 2/3= -8/3
Submarine at a depth of -2 2/3 feet descended by 5 1/2 feet.
So new position of the Submarine = 
To Reach the surface submarine must rise = 0-(-49/6)
As seen from the equation the two negative sign [(-)(-)] will change into a positive sign.
At the surface the position of the submarine = +49/6 feet
No. The absolute value of any number is always positive, as that is its 'absolute value'.
A is the answer hope this helps
<u>Given:</u><u>-</u><u> </u>
- Height of Cylinder = 21ft.
- Radius of Cylinder = 7ft.
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
- Formula for finding surface area of Cylinder = 2πr(r+h)
<u>Putting</u><u> the</u><u> known</u><u> values</u><u> </u><u>,</u><u> </u>
<u>Surface</u><u> Area</u><u> </u><u>=</u><u> </u>2×3.14×7(7+21) ft.²
= <u>1230.88 ft</u>.²
