Maria donates a fixed amount, a, to a charity each month. If she donates $300 in 12 months, what is the equation for a? A.
a + 300 = 12
B.
a × 300 = 12
C.
a × 12 = 300
D.
a + 12 = 300
E.
a + 32 = 100

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

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.  

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
