If a person lives to be 75 years old, which three life stages make up the majority of that person's life? I
a. infancy/toddlerhood, childhood, b. young adulthood, middle adulthood,
adolescence
later adulthood
c. childhood, adolescence, young
d. adolescence, young adulthood, middle
adulthood
adulthood

b is the correct answer

Explanation:

young adulthood = 18 years

middle adulthood = 15 years

later adulthood = 20 years

Later Adulthood.

Explanation:

Later adult hood has the longest reign of age in years sitting at 22, the only other one that comes close is at 18 years for young adults, 15 for medium adults, 10 for adolescents, 8 for childhood, and 4 for infancy.

This means, even though your answer choices are setup in an unorganized fashion, that the answer would have to include all age ranges of young adults, medium adults, and later adult hood. If they include any about childhood, adolescents, or infancy, it is wrong because those 3 main groups, young adults, medium adults, and later adult hood are all larger in the range of ages.

Hope this helps!

"a scientist studying a whale and its surroundings would need to understand the structure of atoms in case something was negatively affecting the whale or its surroundings."

explanation:

this was from the link provided:

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
