Cannot work out part a and b (ii)!
a) The ratio 2.5 metres to 60 centimetres can be written in the form 1:n. Find the value of n.

b) ii) Find the rate at which the water is now flowing from the tap. Give your answer in cubic centimetres per second (cm^3/s).

a)n = 24

b) 100 cm^3/s

Step-by-step explanation:

1/n = 2.5/60

n = 24

b) assuming you are not in calculus, the rate of the water will be constant k.

k = 4000/40 = 100 cm^3/s

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
