S is inversely proportional to t . When s = 0.6 , t = 5 Work out s when t = 0.3
madreJ [45]

Answer:

s = 10

Step-by-step explanation:

Given s is inversely proportional to t , then the equation relating them is

s = \frac{k}{t} ← k is the constant of proportion

To find k use the condition when s = 0.6, t = 5

0.6 = \frac{k}{5} ( multiply both sides by 5 )

3 = k

s = \frac{3}{t} ← equation of proportion

When t = 0.3, then

s = \frac{3}{0.3} = 10

murzikaleks [220]

Answer: 20 feet

Step-by-step explanation:

This represents a right angled triangle with the length of the slide being the hypotenuse, the height of the ladder being the height of the triangle and the distance from the base of the ladder being the length.

Solve with Pythagoras rule:

c² = a² + b²

c = hypotenuse

a= length

b = height

29² = 21² + b²

841 = 441 + b²

b² = 841 - 441

b² = 400

b = √400

b = 20 feet
