Answer 1

Answer: C

Step-by-step explanation: Length of pencil = 15.80 cm

There are 30.48 centimeters in a foot.

i.e.

i.e. Length of pencil (in foot)=

Since 1 foot = 12 inches

Then, Length of pencil (in inches)=

(2)

Length of Candle = 0.303 yards

∵ 1 yard = 3 feet

Then, Length of Candle ( in feet)=

1 foot = 12 inches

then, Length of Candle ( in inches)=

(2)

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

[Add (1) and (2)]

Hence, the best answer is c. 17.13 in .

Answer 2

Answer: c. 17.13 in

Explanation:

Given : Length of pencil = 15.80 cm

There are 30.48 centimeters in a foot.

i.e.
`\text{ 1 cm}=(1)/(30.48)\text{ foot}`

i.e. Length of pencil (in foot)=
`15.80*(1)/(30.48)`

Since 1 foot = 12 inches

Then, Length of pencil (in inches)=
`15.80*(1)/(30.48)*12`

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

Length of Candle = 0.303 yards

∵ 1 yard = 3 feet

Then, Length of Candle ( in feet)=
`3*0.303`

1 foot = 12 inches

then, Length of Candle ( in inches)=
`3*0.303*12=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 .
