You decide to take your car on a drive through Canada, where gas is sold in liters and distances are measured in kilometers. Suppose your car's gas efficiency is 39.0 mi/gal. How many liters of gas will you need to complete a 213 km trip? Use the conversions 1 gal = 3.78 L and 1 km = 0.6214 mi.

12.846 liters

Step-by-step explanation:

Efficiency of car is  39.0 mi/gal

using the conversion given, converting the efficiency of the car from miles/gallon to kilometers/liters.

So,  39.0 mi/gal ÷ 2.352 km/liter

16.5808 km/liter

if  16.5808 km/liter is consuming gas of 1 liter

therefore, for 213 km, it takes gas = 213/ 16.5808

=> 12.846 liters

Thus, you will need 12.846 liters of gas will you need to complete a 213 km trip

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

- 70

this is the answer for you hope it
