Musya8 [376]

Answer: 400 Shoppers

Step-by-step explanation:

Given

156 people spent the night in Wal-mart

These 156 people represent 39% of total shoppers at Wal-mart

Suppose x is the total no of shoppers at Wal-mart

So, we can write

$\Rightarrow 39\%\ \text{of}\ x=156\\\Rightarrow 0.39\times x=156\\\\\Rightarrow x=\dfrac{156}{0.39}=400\ \text{People}$

DIA [1.3K]

Answer:

Option C

Step-by-step explanation:

If we were to consider this question as a whole, all we are being asked is to find an expression equivalent to 2 * ( 5 )^x, as all other function are expressed in the same f ( x ) format. Now all we have to thing about are the expression that = 2 * ( 5 )^2x;

$2( 5 )^2x =\\2( 5^2 )^x =\\2( 25 )^x\\\\Solution - Option C$

Hope that helps!

Graph the equation y=x^2 - <img src="https://tex.z-dn.net/?f=y%20%3D%20x%5E%7B2%7D%20%20-%202" id="TexFormula1" title="y =

rusak2 [61]

Answer:

the graph is attached below

Step-by-step explanation:

$y=x^2 - 2$

LEts make a table to get the coordinates

we need to select integers between -3 and 3

x y=x^2 - 2

-2 y=(-2)^2-2=2 (-2,2)

0 y= (0)^2 - 2= -2 (0,-2)

2 y=(2)^2-2 = 2 (2,2)

Now we use the table for graphing the given equation

The graph is attached below

A rectangular box has length 20cm, width 6cm and height 4cm. find how many cubes of size 2cm that will fit into the box.

Papessa [141]

Answer:

$\boxed{\pink{\sf The \ number \ of \ cubes \ that \ can \ be \ fitted \ is 60 .}}$

Step-by-step explanation:

Given dimensions of the box = 20cm × 6cm × 4cm .

Dimension of the cube = 2cm × 2cm × 2cm .

Therefore the number of cubes that can be fitted into the box will be equal to the Volume of box divided by the Volume of the cube. So ,

$\boxed{\red{\bf \implies No. \ of \ cubes \ = \dfrac{Volume \ of \ box}{Volume \ of \ cube }}}$

$\bf \implies n_{cubes} = \dfrac{20cm \times 6cm \times 4cm .}{2cm \times 2cm \times 2cm } \\\\\bf\implies n_{cubes} = 10 \ times 3cm \times 2cm \\\\\implies \boxed{\bf n_{cubes}= 60 }$

<h3>Hence the number of cubes that can be fitted in the box is 60 .</h3>
