Answer:
Step-by-step explanation:
Given
f(t) = Population of females
g(t) = Population of people
Required
Determine the population of males
Represent the required population with h(t)
With the assumption that, one can either be male or female (but not both), the relationship between f(t), g(t) ang h(t) is:
i.e.
Make h(t) the subject in
Answer:
60 degrees
Step-by-step explanation:
set up like 240-120
240-120=120
120 divided by 2 equals 60
therefor, the angle is 60 degrees
Circumference = 2πr
So the circumference of the track is C = 2π .2 or .4π
3 times around the track is .4π x 3 or 1.2π - this is the answer but most teachers will want you to use 3.14 for pi.
so 1.2 x 3.14 = 3.768 km
Do you notice that I waited until the end to use the actual value of pi (3.14) in my calculations.
Keeping things in pi units until the very end saves time.
Answer:
50.3
Step-by-step explanation:
area of a circle = πr²
where r = radius
given radius = 4yd
so we have A = πr²
==> plug in r = 4 ( because the given radius is 4yd )
A = π(4)²
==> evaluate exponent
A = 16π
==> simplify 16π
A = 50.3 ( rounded to the nearest tenth )
