Writing exercises

Priam bought a jacket that was on sale for $\text{40%}$ off. The original price of the jacket was $\text{150}.$ While the sales clerk figured the price by calculating the amount of discount and then subtracting that amount from $\text{150},$ Priam found the price faster by calculating $\text{60%}$ of $\text{150}.$

1. Explain why Priam was correct.
2. Will Priam's method work for any original price?

1. Priam is correct. The original price is 100%. Since the discount rate was 40%, the sale price was 60% of the original price.
2. Yes.

Roxy bought a scarf on sale for $\text{50%}$ off. The original price of the scarf was $\text{32.90}.$ Roxy claimed that the price she paid for the scarf was the same as the amount she saved. Was Roxy correct? Explain.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

why surface tension is zero at critical temperature
Shanjida
I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
