Answer 1

Answer: c. 17.13 in

Step-by-step explanation:

Given : Length of pencil = 15.80 cm

There are 30.48 centimeters in a foot.

i.e. $\text{ 1 cm}=\dfrac{1}{30.48}\text{ foot}$

i.e. Length of pencil  (in foot)= $15.80\times\dfrac{1}{30.48}$

Since 1 foot = 12 inches

Then,  Length of pencil  (in inches)= $15.80\times\dfrac{1}{30.48}\times12$

$6.22047244094\approx6.22\text{ inches}$             (2)

Length of Candle = 0.303 yards

∵ 1 yard = 3 feet

Then, Length of Candle ( in feet)=$3\times0.303$

1 foot = 12 inches

then, Length of Candle ( in inches)=$3\times0.303\times12=10.908$

$\approx10.91\text{ inches}$              (2)

If the two items placed end-to-end, the total length will be :-

$6.22+1091=17.13\text{ inches}$  [Add (1) and (2)]

Hence, the best answer is c. 17.13 in .
