The answer to your question is 5.21925
0.99755+1.22=2.21755
2.21755+3.0005=5.21805
5.21805+0.0012=5.21925
Hope this helps! :)
Answer:
coefficients =8 and 2/3
constants are also 8 and 2/3
To start, the question is asking for surface area of a cylinder, meaning you will have to use this formula to find it: A=2πrh+2πr^2.
Since you already know that the diameter of the plastic cylinder is 4 marbles long, and each marble is 2 cm in diameter, you would multiply 4 and 2 to get that your diameter is 8 cm. However, since the surface area of a cylinder formula uses radius, you would simply divide 8 by 2 to get that the radius of the cylinder is 4 cm.
Now, since you already know that the height of the cylinder is equal to 10 marbles, multiply the amount of marbles by 2 to get that the height of the cylinder is 20 cm.
Now that you know the height and the diameter of the cylinder, plug the values into the formula: A=2π(4)(20)+2π(4)^2.
Assuming that pi is 3.14, simplify the equation as according to PEMDAS and you get that the area of plastic needed to make one cylinder is 602.88 cm squared
* -21x + 9y = 66
21x + 28y = 28
37y= 94
y= 94/37
* -3x - 4y = -4
-3x - 4(94/37)= -4
-3x = -4 + (4*(94/37))
Answer:
$17,999.10
Step-by-step explanation:
Let x represent the amount the bank will lend.
x = $19,999(1 -10%) = 0.90($19,999) = $17,999.10
The bank is willing to lend $17,999.10 on the car.
