A shadow 4 feet long is cast by a wooden barrel that is 3 feet tall. If a nearby stop sign is 6 feet tall, then how long will the stop sign's shadow be?

4 ft shadow=3 ft tall

?(x)=6 ft

4×6=3x

24=3x

24/3=x

8=x

that's my answer I think

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
