What is 0.50 written as a percent

Debora [2.8K]

There r a couple of ways to do this...

(1) to turn a percent to a decimal, multiply by 100
0.50 * 100 = 50%

(2) to turn a percent to a decimal, move the decimal point two spaces to the right. Making 0.50 = 50%

Use intercepts to graph the line described by the equations-2x-4y=8

tekilochka [14]

-- The x-intercept is the point where the line crosses the x-axis.
So y=0 there.

 -2x - 4y = 8
 -2x - 4(0) = 8
 -2x = 8

Divide each side by -2 : x = -4 => the x-intercept is (-4, 0)

-- The y-intercept is the point where the line crosses the y-axis.
So x=0 there.

 -2x - 4y = 8
 -2(0) - 4y = 8
 -4y = 8

Divide each side by -4 : y = -2 => the y-intercept is (0, -2)

Now you have two points on the graph ... the points where the line crosses each axis.

Mark little dots at both points, then lay your ruler across both dots, and draw
the line along the edge of the ruler, as far as you want to in both directions.

The volume of a cylinder is 32.25 cubic inches. If a cone has the same height and radius as the cylinder, what is its volume?

Whitepunk [10]

This math question is under the Solid Mensuration topic. Let us recap the formulas of the volume of both the cylinder and the cone.
$V_{cylinder}= \pi r^2h$
$V_{cone}= \frac{1}{3} \pi r^{2}h$

So if the volume of the cylinder is 32.25 inches,
$32.25=V_{cylinder}$
Then,
$32.25= \pi r^2h$

So, to obtain the value of the volume of the cone is we simply multiply $\frac{1}{3}$ to both of the sides of the equation.
$\frac{1}{3} 32.25= \frac{1}{3} \pi r^2h$
 $10.75= \frac{1}{3} \pi r^2h$
 $10.75=V_{cone}$ [/tex]
So its value if the radius and its height is the same as to the cylinder is 10.75 cubic inches.

Suppose y varies directly with x, and y= 7 when x = 3. What is the value of x when y = 28? If 7 = k(3) then 28 = k(x) Find x

Rama09 [41]

Let y and x be the numbers that varies directly (that means they keep the same proportion)

Then we have 7y = 3x, OR y/x =7/3 (this ratio should be kept for any value of x and y:
y/x = 7/3, if y = 28, then 28/x = 7/3 or x = (3)(28)/7 = 12

SO X = 12
