Hi there,
Properties of Equality is two equations that have the same solution which are called equivalent equations. For example: 5+3=2+6 which all equal to 8.
In geometry, properties of Equality are the reflexive (2x=2x, a=a, b+1=b+1), symmetric (2a=3b then 3b=2a) and transitive property (if a+1=3 and 3=1-b, then a+1=1-b)
Hope this helped :)
Have a great day
Hello!
First of all we will need to find the circumference, as it is the distance around the wheel. We will use 3.14 for pi.
42(3.14)=131.88
Now we multiply by three to see how far they go in a minute.
131.88(3)=395.64
Now we multiply by 5 to see five minutes.
395.64(5)=1974.2
A passenger will travel approximately 1978.2 feet in 5 minutes.
I hope this helps!
When going through York Canal, his speed is 1 mile per 3 minutes.
If going by this speed while crossing Stover Lake, he would drive 10 miles in 30 minutes.
Therefore, he drove 10 miles.
