just do it with a calculator the answer is -3
Answer: 15.25
1/4 is 0.25, so 15 + 0.25 is 15.25.
Step-by-step explanation:
Before the industrial revolution, most of the moth population had white wings. During and after the industrial revolution, the moth population has evolved to have a majority black population. This happened due to changing natural selection pressures. The black moths were able to camouflage in the ‘dark environment’ caused by soot from the industrial revolution. The moths were less linly to be preyed on compared to white moths that stood out in the ‘black’ environment. Over a generation, the allele for white-color, because it offered a disadvantage, becomes ‘weeded out’ of the population.
Answer:
4(x-7)(x+1)
Step-by-step explanation:
Answer:
64 times more paint will be needed since the volume of the second is 64 times the volume of the first
Step-by-step explanation:
If the original sphere is 12 cm diameter
its radius will be half this measure which is 12/2 = 6 cm
The new diameter is 4 times this, so its radius would be 4 times this and it is 24 cm
Now, the volume of the sphere means we have to raise the power of the radius by 3
The other terms in the formula remains the same for both, so we are simply comparing the radii
so we will have the difference in volume in times of multiples as ;
(24/6)^3 = 4 * 4 * 4 = 64
