The diagram shows a partly-filled petrol tank
a quarter of the tank is filled with petrol
1 cubic metre is equivalent to 1000 litres
work out how many more litres of petrol are needed to fill the tank
height =1.6m
width=2 m
length=1.3m

3120 litres

Step-by-step explanation:

1.6×2×1.3 = 4.16 m³

¼ is filled

1 - ¼ = ¾ is to be filled

¾ × 4.16 = 3.12m³

3.12×1000 = 3120 litres

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
