How do you find the percent of increase from 12 to 18?

1 answer:

4 0

Let's get the data out of the problem:

Nv = 18

Ov = 12

Now, we can apply in this equation that relates the new and the old values:

i = Nv / Ov

i = 18 / 12

i = 1.5

Now, we just consider what has passed from 1, and this is 0.5, converting to percentage it is:

p = 0.5 . 100

p = 50%

The increase was 50%.

Hope it helps.

Graph the following inequality and then select the correct graph below. x - y - 2 ≥ 0

-Dominant- [34]

Answer:

the graph in the attached figure

Step-by-step explanation:

we have

$x-y-2\geq 0$

Isolate the variable y

$-y\geq -x+2$ -----> Multiply by $-1$

$y\leq x-2$

The solution of the inequality is the shaded area below the solid line

The equation of the line is $y= x-2$

The slope of the line is positive

The y-intercept of the line is the point $(0,-2)$

The x-intercept of the line is the point $(2,0)$

Which statement about a dilation with a scale factor of 3 is true?

Valentin [98]

Given : dilation with a scale factor of 3

To find : Which statement is true

Solution:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size

if Dilation factor N then image Size is multiplied by N

if Scale factor < 1 then image get reduced

if scale factor > 1 then image get enlarged

scale factor = 1 lead to Same size image

Here is given that Scale factor of 3

=> image will be enlarged to 3 times the original image

Hence correct option is :

C)Each side in the pre-image is multiplied by three to find the corresponding side length in the image

Find the volume of the cone.

Ne4ueva [31]

Answer:

3142.86 cubic cm

Step-by-step explanation:

volume of cone is given by formula

volume of cone = 1/3(area of base*height)

Given radius of base = 10cm

we know area of circle is given by $\pi r^2$ where r is radius of circle

thus area of base of cone is calculated below

$\pi 10^2\\=> 22/7 *100\\=> 314.2857$

area of base of cone is 314.2857 square cm

height = 30 cm

Thus volume of cone = 1/3* (area of base*height)

= 1/3(314.2857*30)

= 1/3 *9428.571 = 3142.857.

Thus, volume of cone is 3142.857 cubic cm.

volume of cone to the nearest hundredth is 3142.86 cubic cm
