First calculate the circumference. Usually this is the diameter times pi, but since we are told to estimate pi, the circumference equals 56 * 22/7 or 176 feet.
In 4 minutes, 4 * 60 = 240 seconds pass. In this time, a 20 second period will occur 240/20 = 12 times.
So we know that the rider rotates 12 times and each rotation takes them 176 feet, meaning that they will travel 12 * 176 = 2112 feet
Answer:
4x12=48
Step-by-step explanation:
1 car=4 wheels
12cars= 48 wheels
Answer:
There are 40 more females than males.
In total there would be 60 females, and 20 males.
Step-by-step explanation:
If you mean
the decomposition would be of the form
We have
which gives
Or, if you prefer the standard approach, combining the partial fractions on the right side of the equation above would have given
so that
Solve for <em>a</em> and <em>b</em> :
Answer:
x = -5
Step-by-step explanation:
The equation y = x^2+10x+25 can be factored to (x+5)^2
when (x+5)^2 = 0
x = -5
meaning the equation has a line of symmetry at x = -5
