Answer:
Perimeter = 21 units
Volume = 110 cubic units
Step-by-step explanation:
Let the center of circle be (x,y).
4x - 18y = - 45
4x + 8y = 4
x + 2y = 1
Solving these 2 equations,
4 - 26y = -45
y =
x =
radius = 3.35
Perimeter = 2 = 21 units
Volume of cylinder =
We have to add the volumes of the cylinders.
Volume of smaller cylinder = = 8
Volume of larger cylinder = 27
Total volume = 35 = 110 cubic feet
18-carat gold is 75 percent pure, and gold ratings are proportional, you know that...
<span>18 / 75 = 24 / x </span>
<span>X needs to have the same relationship to 24 that 75 has to 18. </span>
To solve, simply cross-multiply (multiply the numerator in one fraction by the denominator in the opposite fraction, and vice versa). The resulting products will be equal. Then, simply divide away the remaining coefficient to solve for x.
<span>18 / 75 = 24 / x </span>
<span>18x = 24 * 75 = 1800 </span>
<span>x = 1800 / 18 = 100 </span>
<span>x = 100 </span>
<span>Therefore, the purity of 24 carat gold is 100%.</span>
