60 out of 1240 fruit trees are poisonous. What percent of trees are poisoned? Round to the nearest tenth.

4.8%

Step-by-step explanation:

to do this create a ratio and cross-multiply

now that we have a our ratio, where x = the percent of poisonous trees, we can cross-multiply and solve to find its value

cross-multiplying leaves you with

now solve for x, dividing both sides of your equation by 1240

once you've divided, you should be left with

since this number is already out of 100, it is equivalent to your percent, so slap a percent sign on the end and you're done!

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

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.
