Answer:
t = d/r
Step-by-step explanation:
Given the equation, d = rt for <em>t</em><em>:</em>
Switch sides:
rt = d
Divide both sides by r to isolate<em> t</em>:<em> </em>

t = d/r
Answer:
man's age = 54
daughter's age = 18
Step-by-step explanation:
x = man's age
y = daughters age
x = 3y
x - y = 36
substitute for x:
3y -y = 36
2y = 36
y = 18
x = 54
Answer:
V = π /2 volume units
Step-by-step explanation:
Volume of y = √x bounded by y = x and y = 1
y = √x
limits of integration ( see Annex )
By simple inspection limits of integration are x = 0 to x = 1
or y = √x and y = x
solving these two equations
x = 0 y = 0 x = 1 y = ± 1
V = ∫ π*f(x)²*dx
V = π * ∫₀¹ x*dx = π * x²/2 |₀¹
V = π * (1/2) - 0
V = π /2 volume units

Answer:
18,432 Km/ h
Step-by-step explanation:
Using the conversions
• 1 Km = 1000 m
• 1 hour = 60 × 60 = 3600 seconds
Then
5120 m =
= 5.12 Km and
5.12 Km × 3600 = 18,432 Km / hour
