The difference between a number divided by 3 and 4 is 20.
Alexxandr [17]
Let, the number be "a"

Now, according to the question,
\frac{a}{3} - 4=20

\frac{a-12}{3} =20

a-12 =20*3

a-12=60

a = 60 + 12

a = 72


So, the number is 72

Someone please solve & explain
den301095 [7]

Answer:

y+20 = 9(x+2)

Step-by-step explanation:

The slope that passes through the points is

m = (y2-y1)/(x2-x1)

    = (79- -20)/ (9--2)

    = (79+20)/(9+2)

     = 99/11

     = 9

We can use point slope form to write an equation.  It says to use the first point.

y-y1 = m(x-x1)

y--20 = 9(x--2)

y+20 = 9(x+2)

The height of a rectangular prism is half its width The width of the prism is 1/3 of its length If the width of the prism is 3 c
Leno4ka [110]

Answer:

40.5 centimeters.

Step-by-step explanation:

Given:

The width of the prism is 3 centimeters.

The width of the prism is 1/3 of its length.

The height of a rectangular prism is half its width.

To find:

<u>Volume of a rectangular prism = ?</u>

Solution:

Width of the prism = 3 cm

As given, height of a rectangular prism is half its width.

height of a rectangular prism = \frac{1}{2} \times3=\frac{3}{2} \ cm

Similarly, as given, the width of the prism is 1/3 of its length.

Width of the prism = \frac{1}{3}\  of\ length

                            3=\frac{1}{3}\times length

By multiplying both sides by 3

                            3\times3=\frac{1}{3} \times3\ length\\9= length\\

Thus, length of prism = 9 cm

Now, as we know:

Volume\ of\ rectangular\ prism=length\times breadth\times height

                                                 =9\times3\times\frac{3}{2} \\\\ =\frac{81}{2} \\ \\ =40.5\ cm

Therefore, the volume of a rectangular prism is 40.5 centimeters.
