An open topped box is constructed as follows: A 24 in. x 24 in. square bottom has four identical squares cut off at each corner.

Arte-miy333 [17]

Answer:

Step-by-step explanation:

Given

square bottom area is $24\times 24\ in.^2$

Suppose x in. is cut from each corner to make a open box with maximum volume

New base area is $(24-x)\times (24-x) in.^2$

Volume of box

$V=(24-x)^2\times x$

Differentiate V w.r.t x to get maximum volume

$\frac{\mathrm{d} V}{\mathrm{d} x}=2\cdot (24-x)(-1)+1\cdot (24-x)^2$

Put $\frac{\mathrm{d} V}{\mathrm{d} x}=0$

$\left ( 24-x\right )\left [ -2x+24-x\right ]=0$

$\left ( 24-x\right )\left [ 24-3x\right ]=0$

$x=24,8$

but x=24 is not possible therefore x=8 will yield maximum volume

$V=(24-8)^2\cdot 8=2048\ in.^2$

a washer and dryer costs $951 combined. The washer costs $51 more than the dryer. what is the cost of the dryer?

Over [174]

Answer:

$450

Step-by-step explanation:

We know that the washer costs $51 more dollars than the dryer.

The washer costs x+51

The dryer costs x

So to simplify this we can do this equation:

2x+51=951

Substitute and simply the equation, and you should get this:

2x=900

x=450

Hope this helps! :)

So this has to do with permutations and honestly I need an explanation on how I can figure these out.

AnnZ [28]

Well, the answer quite simple ....there are 4! ways to arrange these numbers...and as 4! = 4*3*2*1 = 24

hence 24 is the correct answer....

u can also remember it by theorem of multiplication as.....in first place (I.e. first code can be any no. out of 4,5,2&7 ....so 4*.....

as first place is acquired by a certain no. that leaves three no. to fill third place and when third place I'd occupied it leaves 2 numbers to fill second place and lastly only one no. to fill the last place .....so it's result will be like 4*3*2*1.

I know this is pretty much confusing ....but still I tried my best....

if anything troubles u here feel free to ask me
