Answer:

97.8 liters

Step-by-step explanation:

We use proportions:

If 7.4 liters are needed for 100 km, then we can write the rate:

7.4 L / 100 km  which should equal the rate for the x number of liters needed for a 1322 km trip:

7.4 L / 100 km = x / 1322 km

solving for "x" by multiplying both sides by 1322:

x = 97.828 liters

which we may be able to round to 97.8 liters

There were 63 equal piles of plantain fruit put together and 7 single fruits. They were divided evenly among 23 travelers. What
antiseptic1488 [7]

Answer:

There are 28 fruits in each pile.

Step-by-step explanation:

We are given the following in the question:

Let x denote the number of fruits in each pile and y denote the number of fruits that every traveler receive.

Consider the diophantine equation:

63x + 7 = 23y\\63x-23y = -7

We obtain the greatest common divisor of (63,-23).

The greatest common divisor f 63 and -23 is 1.

Therefore, there exist \alpha,\beta such that

-23\alpha+63\beta=1

By applying extended Euclidean Algorithm, we have,

1 = (1\times 6)+(-1\times 5)\\1 = (1\times 17)+(3\times 6)\\1 = (3\times 23)+(-4\times 17)\\1 = (-4\times 40)+(7\times 23)\\1 = (7\times 63)+(-11\times 40)\\1 = (-11\times -23)+(-4\times 63)

1 = (-11\times -23) + (-4\times 63)

Multiplying -7 on both sides, we get,

-7 = (77\times -23) + 28\times 63)

Thus, we get,

x = 28\\y=77

Thus, there are 28 fruits in each pile.
