Answer:

Step-by-step explanation:

$x+4y-3z=1$

$x=1-4y+3z$

$3(1-4y+3z)+12y-9z=8$

$3-12y+9z+12y-9z=8$

$3=8$

so your answer is No solution

Whats the Diameter? I really need help understanding this

Arada [10]

Answer:

1.8 in.

Step-by-step explanation:

Hi there!

<u>1) Determine the radius of the base</u>

$V=\frac{1}{3} \pi r^2h$ where r is the radius of the base and h is the height of the cone

Plug in the known values (h=4.2, V=3.6)

$3.6=\frac{1}{3} \pi r^2(4.2)$

Isolate r; divide both sides by 4.2

$\frac{3.6}{4.2} =\frac{1}{3} \pi r^2\\\frac{6}{7} =\frac{1}{3} \pi r^2$

Multiply both sides by 3

$\frac{6}{7}*3 =\pi r^2\\\frac{18}{7}=\pi r^2$

Divide both sides by π

$\frac{18}{7\pi }=r^2$

Take the square root of both sides

$\sqrt{\frac{18}{7\pi }} =r$

<u>2) Determine the diameter</u>

Now that we have the radius, to find the diameter, multiply r by 2:

$d=\sqrt{\frac{18}{7\pi }}*2\\d=1.8$

Therefore, the diameter is 1.8 in. when rounded to the nearest tenth.

I hope this helps!
