Mallorie has $5 in her wallet. If this is 10% of her monthly allowance, what is her monthly allowance? Jacob has $10 in his wallet. If this is 40% of his weekly allowance, what is his weekly allowance?

13 is 26% of what number?

In the first year, a new car can lose 20% of its value. If a car lost $4,200 of value in the first year, how much did the car originally cost?

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

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.
