Answer:
20 ft
Step-by-step explanation:
Keep in mind that, both ratios are the same, let the length of the shadow be x, then you can make an equation that 30/ 40 = 15 / x, then 30x = 15 * 40 = 600, so x = 20.
Answer:
5,000 meters * 1 kilometer / 1,000 meters = 5 kilometers answer is B
Step-by-step explanation:
I am probably wrong but it might be 28 or 28.3 (I’m really sorry if this is wrong lol)
So you are given a recursive series, which is an equation that writes itself. Now we want to create a explicit rule. Explicit rule is a pattern that uses our first term and add our common difference. So it gives us our first term.

Lets find the second term of the recursive series.
a_2 = -3 +7 = 4
So it is increasing by 7
So our explicit rule is:
a_n = -3 + 7(n-1)
Answer:
put b because u can see that
