Answer:

64.80

Step-by-step explanation:

Sathish is alone for 150 at the beginning and 150 at the end for 300 km

2100 - 300 = 1800

He shares the trip with his 2 friends for 1800 km

We will use ratio to determine the gas need for this part of the trip

100 km       1800 km

---------- = ------------

6 liter          x liters

Using cross products

100x = 1800*6

100x =10800

Divide each side by 100

100x/100 = 10800/100

x = 108 liters

It costs 1.2 per liter

108*1.2 =129.6

But this is divided by 3  (Sathish and his 2 friends)

129.6/3 =43.2

Now we need to find how much for his solo part

100 km       300 km

---------- = ------------

6 liter          x liters

100x = 6*300

100x = 1800

Divide by 100

100x/100 =1800/100

x = 18

It costs 1.2 per liter

18*1.2 =21.6

Add his two costs together

43.20+21.60 =64.80

9.1 x 10-31 kg.
Reptile [31]
1 electron has a mass of 9.1 X 10-31 kg. How many electrons n does it take to make 1 kg?

(1 e)/(9.1 X 10-31 kg) = n/(1 kg)

So, n = 1.10 X 1030 electrons

Each electron has a charge of 1.6 X 10-19 C, where C stands for Coulombs. So, the n electrons have a charge of q = ne = (1.10 X 1030 electrons) X (1.6 X 10-19 C/electron) = 1.76 X 1011 C.
