-7.2x+112.32= -9
-7.2x= -9-112.32
-7.2x= -121.32
x= -121.32/ -7.2
x=16.85

WHY CAN'T ANYONE HELP ME? PLEASE What one is the standard form of the equation y = – 1/4 x – 2? A. x + 4y = 8 B. x + 4y = – 2 C.

Answer:

C. x+4y=-8

Step-by-step explanation:

The standard form of an equation is Ax+Bx=C

y= - $\frac{1}{4}$ x-2

Multiply 4 by both sides

4y= -x-8

1+4y= -8

The volume of a cylinder is 539 cm cube and the circumference of the base is 22 cm. find the height of the cylinder.

Alexandra [31]

Answer:

13.994 $cm (5.sf)$

Step-by-step explanation:

We know that the base of the cylinder is a circular base.

So circumference of base = $2\pi r$

Given $2\pi r=22cm\\\\r=\frac{22}{2\pi } \\r=\frac{11}{\pi } cm\\$

Volume of a cylinder = $\pi r^{2} h$ = 539 $cm^{3}$

Substitute r into the formula for volume of cylinder.

$\pi (\frac{11}{\pi } )^{2} h=539\\\pi (\frac{121}{\pi ^{2} } )h=539$

Now, we will cancel $\pi$ from the numerator and denominator.

$(\frac{121}{\pi } )h=539\\h = \frac{539}{\frac{121}{\pi } } \\h = 539 * \frac{\pi }{121} \\h = 13.994cm(5s.f)$
