den301095 [7]

Answer:

24 feet

Step-by-step explanation:

We are given that an open box is to be constructed from a square piece of sheet metal by removing a square side 6 feet from each corner and turning up the edges.

We have to find the dimensions of the sheet metal

Let x feet be the side of square metal sheet

Length of box=x-12 feet (because 6 feet removed from each corner)

Width of box=x-12 feet

Height of box=6 feet

Volume of box=864 cubic feet

We know that volume of cuboid= $l\times b\times h$

Box is in cuboid shaped

Therefore, volume of box= $6(x-12)(x-12)$

$6(x^2-24x+144)=864$

$x^2-24x+144=\frac{864}{6}$

$x^2-24x+144=144$

$x^2-24x+144-144=0$

$x(x-24)=0$

Then , $x=0 , x-24=0$

$x=24$

x=0 is not possible because side of square metal sheet can not be zero

Therefore, x=24

All sides of square metal sheet are equal.

Hence, side of square metal sheet =24 feet

Moshde runs a hairstyling business from her house. She charges $48 for a haircut and style. Her monthly expenses are $1100. She

AlexFokin [52]

Answer: 48

Step-by-step explanation:

Moshde charges 48 dollars for haircut + style

She loses 1100 dollars over expenses.

If she wants to get a revenue of 1168 dollars:

$1168 + $1100 = $2268

She has to make $2268 dollars

2268/48 = 47.25

Therefore, 47.25 haircuts are needed.

Of course, this is silly and ridiculous. How can you give fractions of a haircut, therefore, we round UP for 48 haircuts at minimum.

I hope this helps :)

Lisa and Daisy work at a hair salon. The salon charges $18 for a hair styling session with Lisa and $12 for a session with Daisy

Zina [86]

You would want to divide 216 by 18 and by doing that you would get 12.
