An open box is made from a 20 cm x 3 cm piece of tin by cutting a square from each corner and folding up the edges. The area of

Marta_Voda [28]

Answer:

Length of the final sides: 6 cm and 16 cm

Step-by-step explanation:

The lengths of the sides of the original box are

$L=20 cm\\W=10 cm$

Later, a piece of tin is cut out from each corner; the piece cut out has the shape of the square: we can call the length of its generic side x. Therefore, the dimensions of the box will now be:

$L'=L-2x\\W'=W-2x$

We also know that the area is

$A=96 cm^2$

And the area can be written as product of length and width, therefore:

$A=L'W'$

So we find:

$A=(L-2x)(W-2x)\\96=(20-2x)(10-2x)$

Solving for x,

$96=200-20x-40x+4x^2\\4x^2-60x+104=0\\\\x^2-15x-26=0$

Which has two solutions:

x = 13 cm (this is larger than the initial length of the width, therefore we discard it)

x = 2 cm

So, the length of the new sides are

$L=20-2x=20-2(2)=16 cm\\W=10-2x=10-2(2)=6 cm$

Answer:

1.) 7

2.)7

3.)-7

4.)7

5.)7

Step-by-step explanation:

1.) Just count -2 to 5 with your hands

2.) since two negative signs make a addition sign when they are close to each other, you will just add 5 and 2.

3.) Just add 5 and 2 and add the negative sign before the number.

4.)Same as I said in number 2, it stays 7.

5.) Finally, as number 3, it will be -7 but because of the negative signs it will be 7.

A) a shopkeeper buys a camera for $300 and sells it at $360. Calculate the percentage profit.

Lilit [14]

A) profit/original price x100 =percentage profit

(Profit: 360-300=$60)

=60/300 x100
=20%

b) two cameras (original price): 300x2= $600
two cameras (price sold): 360x2 = $720

Profit without discount: 720-600= $120

120-100= $20 discount

20/720 x100 =2.78%
