Since you're given the number of meters in a mile and seconds in a hour, you have
So, 65 miles per hour are equivalent to
Answer:
Robyn model makes more sense and Mark's is nonsense
Step-by-step explanation:
In this question ,calculations not required .All we have to do is consider each model logically .
Marks
Marks model shows 20 rather than 2 which means 200 is 10 times as much as 20. It does not make any sense.
Robyn
Robyn model shows 2 which means 200 is 100 times as much as 2 and this is not only correct but also makes sense because 100 *2=200
Answer:
Step-by-step explanation:
False if you rely solely on deduction you may miss importent details to support your claim. you conclusion should summarize all your points, not just one.
Listing out a few elements of the set of perfect squares, we get the following values
{1, 4, 9, 16, 25, 36, 49, 64, 81, 100, ...}
we can stop there because 82 is between 81 and 100
So if x^2 = 82, then x^2 is between 81 and 100 meaning
81 < x^2 < 100
apply the square root to all sides of the compound inequality and we get
9 < x < 10
So the square root of 81 is between 9 and 10
Answer: the value falls between 9 and 10
Answer:
Step-by-step explanation:
4(2x-1)=3x+5-x
8x-4=3x+5-x
8x-4=2x+5
6x-4=5
6x=9
x=3/2
