DiKsa [7]

8,900. 20% of 22,000 is 2,400 so multiple that by two and you get 8,900 then y’all subtract 8,900 by the 22,000 and get 13,100

(w^5 z^2 )(−9w^2 z^5)

Lady_Fox [76]

We have that
(w^5*z^2)*(-9*w^2*z^5)

Multiplying exponential expressions
we know that
w^5 multiplied by w^2 = w^(5 + 2) = w^7
and
z^2 multiplied by z^5 = z^(2 + 5) = z^7

therefore
(w^5*z^2)*(-9*w^2*z^5) =-9*( w^7)*( z^7)
-9*( w^7)*( z^7)=-(3^2)*( w^7)*( z^7)

the answer is
-(3^2)*( w^7)*( z^7

Solve the system using elimination. 5x + 8y = –29 7x – 2y = –67

Snowcat [4.5K]

7x-2y+-67
multiply both sides of the bottom by 4 and add 5x+8y=-29 
 28x-8y=268

33x=-297
 x=-9 

5(-9) +8y= -29 
-45 +8y =-29 
8y= 16 
y=2

A pyramid has a square base with sides of length s. The height of the pyramid is equal to - of the length of a side on the base.

Vera_Pavlovna [14]

<h3>Question:</h3>

A pyramid has a square base with sides of length s. The height of the pyramid is equal to 1/2 of the length of a side on the base. Which formula represents the volume of the pyramid?

<h3>Answer:</h3>

The formula represents the volume of the pyramid is:

$V=\frac{1}{6}s^3$

<h3>Solution:</h3>

The volume of square pyramid is given by formula:

$V = \frac{1}{3} a^2h$

Where, "h" is the height of pyramid

"a" is the length of side of base

Here given that, pyramid has a square base with sides of length s

Therefore,

a = s

The height of the pyramid is equal to 1/2 of the length of a side on the base

$h = \frac{1}{2} \times s\\\\h = \frac{s}{2}$

Thus the volume of pyramid becomes:

$V = \frac{1}{3} \times s^2 \times \frac{s}{2}\\\\V = \frac{s^3}{6}$

$\boxed{V=\frac{1}{6}s^3}$

Thus the formula represents the volume of the pyramid is $\frac{s^3}{6}$

Multiply both sides of the each equation in order to get the coefficient to be an integer.

monitta

$45= \frac{1}{2}a-3 //+3 \\ 48= \frac{1}{2} a// : \frac{1}{2} \\ 48: \frac{1}{2}=a=\ \textgreater \ 48*2=a=\ \textgreater \ a=96$
Hope that helps.Have a nice day!! ^^
