Answer:
x=11 and the number of solutions is one solution
Step-by-step explanation:
The square root of 121 is 11. There are no other solutions, I believe.
Answer:
It should be the last one because rigid transformations doesn't change in size just where it is
Answer:
135 cm
Step-by-step explanation:
Let Jose's height = x
The mean of their heights = 150
Given the Heights:
150cm, 170cm, 140cm, 155cm
The mean is the sum if the heights divided by the number of people
Here :
(150 + 170 + 140 + 155 + x) / 5 = 150
(615 + x) / 5 = 150
615 + x = 750
x = 750 - 615
x = 135 cm
Answer:
A mile is equal to 5280 feet
You start off with
200 miles per hour
If you multiply 200 by 5280 you can find the speed in feet per hour
1,056,000 feet per hour
There are 60 minutes in an hour
If you divide 1,056,000 by 60 you can find the speed in feet per minute
So 17,600 feet per minute
Then if you divide that by 60 you can find the speed in feet per seconds
It is 293 1/3 or 293.333 feet per second.
Step-by-step explanation:
By definition, if is the least upper bound of the set , it means two thing:
In other words, the least upper bound of a set is greater than or equal to every single element of the set, but it is "close enough" to the elements of the set, because you guaranteed to find elements in the set between and
For example, pick . Obvisouly, the least upper bound is . In fact, every number in is smaller than 10, but as soon as you take away something from 10, say 0.01, you get 9.99, and there are elements in greater than 9.99, say 9.9999.
So, the claim is basically proven by definition: if , let . By definition, there exists .
