4 1/3 ➡ 13/3

5 1/6 ➡ 31/6

to divide two rational expression you should turn the second number upside-down(finding its reciprocal) then multiply them :

13/3 × 6/31 = 26/31

The height and diameter of a cylindrical cup are the same length. The volume of the cup is 54pi in3 what is the radius and the h

ASHA 777 [7]

Answer:

The radius of the cup is $3\ in$ and

the height of the cup is $6\ in$

Step-by-step explanation:

we know that

The volume of the cylinder is equal to

$V=\pi r^{2}h$

Let

x-----> the height and the diameter of the cylinder

we have

$V=54\pi\ in^{3}$

$h=x\ in$

$D=x\ in$

$r=(x/2)\ in$

substitute the values

$54\pi=\pi (x/2)^{2}(x)$

simplify

$54=(x/2)^{2}(x)$

$54=\frac{x^{3}}{4} \\ \\x^{3}=216\\ \\x=6\ in$

therefore

The radius of the cup is

$r=(6/2)=3\ in$

The height of the cup is

$h=6\ in$

If $y=x+6$ and $y=-2x-3$ , then you can replace $y$ in either equation with the equivalent expression given by the other equation. In this case, you have

$x+6=-2x-3$

and you can solve for $x$ .

$x+2x+6-6=-2x+2x-3+6\implies3x=3\implies\dfrac{3x}3=\dfrac33\impliesx=1$

Then $y=1+6=7$ .

For the second system, you can write

$5x-y=-5\implies 5x-5x-y=-5-5x\implies-y=-5-5x$

$\implies-(-y)=-(-5-5x)\implies y=5+5x$

Then substitute this into the second equation and you get

$3x-6(5+5x)=24\implies3x-30-30x=24\implies-27x-30+30=24+30$

$\implies-27x=54\implies x=2$

so that

$y=5+5(2)=15$
