Answer:

There are 7 chairs in each row.

Step-by-step explanation:

Hue is arranging some number of chairs. If she arranges them in 6 rows of equal lengths then there will be 3 chairs leftover, or she arranges them in 8 rows of that same length then she requires 11 more chairs.

Let us assume that there are P numbers of chairs and there are x chairs in each row.

Therefore, we can write that  

6x + 3 = P ....... (1) and  

8x = P + 11  

⇒ 8x - 11 = P ........ (2)

Now, from equations (1) and (2) we get,

6x + 3 = 8x - 11

⇒ 2x = 14

⇒ x = 7

Therefore, there are 7 chairs in each row. (Answer)

Nana76 [90]

Y = mx + c

7= (-5)(-2)+ c

7= 10 +c

7-10=c

-3=c

Equation of the line: y = -5x-3

Sub in (a, 2)

2= - 5(a)-3

2+3= -5a

5= - 5a

1= - a

A = -1

Find the derivative of f(x) = 7 divided by x at x = 1.
julsineya [31]
I find it best to switch everything exponents when taking derivatives.
F(x) = 7/x
Same as..
F(x) = 7x^-1
Take derivative..
F'(x) = -7x^-2
Plug in x = 1
F'(1) = -7(1)^-2
F'(1) = -7

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.
