the perimeter of a rectangle is 62 feet.if the width of the rectangle is 19ft. what is the length of the rectangle
denis23 [38]
Perimeter = 2(l+w) or 2(length+width)

So far you have the width, which is 19feet. Since you have two sides of the rectangle which are 19 feet, add 19+19=38

Subtract 62-38 to get 24.

You now have the length of both of the sides combined. So you need to divide 24/2 = 12
The length of the rectangle = 12ft.

bezimeni [28]

Answer: k = - 6.6667

Step-by-step explanation:

this is quite very simple to begin. I would encourage you take other practice questions similar to help with understanding it.

let us begin.

Given that ;

dT/dt = k ( Tm - T)       where Tm is the temp of the medium

dT/dt = 5 degrees Celsius per minute    when T = 70

so we have that, 5 = k ( 25 - 70)

remember to convert 5 degree celsius per minute to seconds

we have that;

5*60(sec) = k ( 25 - 70)  

k = 5*60 / ( 25 - 70)

k = - 6.6667

note K is negative because we consider it for cooling process  (temp decreasing).

cheers i hope this helps!!!
