Answer:
or
Step-by-step explanation:
we know that
One astronomical unit is about 93,000,000 miles
so
using proportion
Find out how many astronomical unit represent 20,000 miles
Let
x ----> the number of astronomical unit
simplify
or
Since the ratio is 3:4, and 12/4 is 3 than you do 3x3 and get 9 so the answer is 9:12 or 9 boys and 12 girls. To check your answer, you can do 3/4 (for 3:4) and that is 0.75. If you do that with 9:12 you also get 0.75.
5 ≥ 2, so the second rule of <em>C(x)</em> applies :
<em>C</em> (5) = 25 + 3•(5 - 2) = 25 + 3•3 = 25 + 9 = 34
Yea do you have anything that can show for the question then I might help with your questions:)
Answer:
37
Step-by-step explanation:
Substitute x = 10 into g(x), then substitute the result into f(x)
g(10) = 10 - 4 = 6, then
f(6) = 6² + 1 = 36 + 1 = 37
