There are multiple chickens and rabbits in a cage. There are 72 heads and 200 feet inside the cage. How many chickens and how many rabbits?
Answers
heads = 72
feet = 200
Chicken = c
Rabbit = r
c + r = 72
2c + 4r = 200
c = 72 - r
2c + 4r = 200
2(72-r) + 4r = 200
144 - 2r + 4r = 200
2r = 200 - 144
2r = 56
r = 56/2
r = 28
c = 72 - r
c = 72 - 28
c = 44
There are 44 chicken and 28 rabbits.

a) How far does the earth travel in one orbit about the
sun? That is, what is the approximate circumference of the earth's path?
b) Approximately how fast is the earth traveling in its orbit in space? Calculate
your answer in miles per hour.
Answers
a. The circumference should be 186000000π mile
b. The speed of the earth should be 7750000π miles per hour.
Calculation of the circumference & speed of the earth:
Since the radius is 93000000 miles
a.
So, here the circumference is
= 2πr
= 2π(93000000) miles
= 186000000π miles
b) Now the speed is
speed = distance ÷ time
Here the time should be 24 hours
So,
Speed = 186000000π ÷ 24
= 7750000π miles per hour

The circumference= 186000000π miles and the speed or the earth is 7750000π miles per hour.
Step-by-step explanation:
Radius (r) = 93000000 miles
a) circumference= 2πr
= 2π(93000000) miles
= 186000000π miles
b) speed = distance / time
Here distance is the circumference and time is 24hrs because if the earth completes 1 revolution around the sun in 24hrs.
Speed = 186000000π/24
= 7750000π miles per hour

Answer:
The answer is
Step-by-step explanation:
In order to determine the answer, we have to know that it means "solution".
In any expression where there is a variable, we can replace any value in the variable and we get a result. When we replace a value that it makes the expression equal to zero, that value is called "solution".
So in this case, we have to find a solution for "m":
Finally, the solution is only one and it is 8.
(m - 8)
if m = 8,
Solution for the expression m - 8 = 8 - 8 = 0.
So there is only 1 solution for the expression.
