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

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
