Lsat month, harri drove 850 miles in his car. his car's fuel consumption is 45.6 miles per gallon. petrol cost £1.09 per litre. given that 8pints = 1gallon, work out how much Harri spent on fuel last month. You must show working out.

£76.904

Step-by-step explanation:

Lsat month, harri drove 850 miles in his car. his car's fuel consumption is 45.6 miles per gallon. petrol cost £1.09 per litre. given that 8pints = 1gallon, work out how much Harri spent on fuel last month. You must show working out.

a) 45.6 miles per gallon

45.6 miles = 1 gallon

850 miles = x

Cross Multiply

x = 850/45.6

x = 18.640350877 gallons

b) 8pints = 1gallon,

8 pints = 3.785 litres

1 gallon = 3.785 litree

18.640350877 gallons = y

Cross Multiply

18.640350877 litres × 3.785

= 70.5537280694 gallons

c) 1 litres = £1.09

70.5537280694 litres = z

Cross Multiply

z = 70.5537280694 × £ 1.09

z = £76.9035635957

Approximately = £76.904

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
