Adelia had 4 dollars. she found 50 cents then bought a snack. she ended up with 6 quarters.

Adelia brought a snack that costed 3 dollars.

Step-by-step explanation:

4 quarters in each dollar

(4dollars*4quarters)

$4.00=16 quarters

(she found 2 more quarters)

16+2=18

0.25*18= $4.50

She brought a snack that left her with 6 quarters ($1.50)

$4.50-$1.50=$3.00

Adelia brought a snack for $3.00

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

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.
