Use a proportion to find the length of side x for pair of similar figures. there a small triangle and a big triangle small triangle 14cm and 10cm big triangle x and 22 cm

14/10=x/22

X is equal to 30.8

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

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.
