The area of a rectangular park is 82,520 square feet. the length of the park is 350 feet. which equation can u use to find w, the width of the garden in feet?
350 x w =82,520
82,520-w=350
2w+2(350)=82,520
82,520 x 350=w

The equation used to find the width of the garden in feet is 350 x w = 82520 Hence Option 1 is correct

Solution:

Given that area of rectangular park = 82,520 square feet

Length of rectangular park = 350 feet

Width of rectangular park in feet is represented by variable w.

Need to identify correct expression from given expressions which can be used to get value of variable w , width of park.

As area of rectangle = length x width  

so area of rectangular park = length of the park x width of the park

On substituting the given values of area , length and width as variable w is above formula we get

82520 = 350 x w

=> 350 x w = 82520

Hence first expression that is 350 x w = 82520 can be use to find width w  of the garden in feet.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

solution:

the given function is ,

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
