Answer:
539
Step-by-step explanation:
Let the total population of grizzly bears=x
In the first capture, 97 were tagged.
Therefore, ratio of the total population to the tagged=x:97
A month later, when 200 bears were captured, 36 were tagged.
Ratio of the sample to the tagged=200:36
Since a sample is representative of the population, the ratios are the same. We therefore have:
x:97=200:36
There are about 539 grizzly bears in the population
Answer:
<u><em>14 pounds of strawberries and 42 pounds of peaches are sold</em></u>
Step-by-step explanation:
Suppose the pounds of strawberries sold are x and pounds of peaches sold are y. then
$182= x(1) + y(4)--------A
or 182= x(1) +3x(4)------- B
182=x+12x
182/13=x
x=14
A:line and a prism.
B:line and rectangle
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).
