Well there can be two different solutions for this but i will choose the easier one. Obviously one requires a system of equations which obviously will involve a lot of thinking and some good algebra solving in order for them to solve.
As for hit and trial it is very easy, we can just keep adding the distance as we know they are in different directions. 450 + 550 = 1000. So 1000 x 4 = 4000 miles. So after around 4 hours they will be 4000 miles apart if they continue at the same pace.
Answer:
A)100 in
Step-by-step explanation:
Given: Radius of circular table= 16 inches
Now, solving for circumference of the tabletop.
Remember, circumference of circle= 
we know pi= 3.14
∴ Circumference= 
⇒ Circumference of circular tabletop= 100.48 in ≅ 
∴ Circumference of circular tabletop is 100 in.
This is simple!
To begin with, arrange all the numbers in order.
#1
5, 5, 20, 20, 25, 30, 35Mean: add all the numbers together and divide it by how many numbers are there
5+5+20+20+25+30+35=140
there are 7 numbers
Mean:
= 20
Median: The middle number, if the set of numbers have an odd number, then the one in between is the median, if there it is an even number, then the mean of the two in-between numbers is the median.
Median: 20
Mode: The most repeated numbers
Mode: 5 and 20
Range: Highest number - lowest number
Range: 35 - 5
30#2
Order: 44, 48, 48, 49, 59, 61, 63, 68Mean: 440 (sum of all numbers)
there are 8 numbers in total

=
55
Median: there are 8 numbers so, the mean of the in-between numbers will be the median
49+59=108
2 numbers

=
54
Mode: 48
Range = 68 - 44 = 24
