Answer: 32.5 units (choice C)</h3>
This value is approximate.
=============================================================
Explanation:
To find the perimeter, we simply add up the lengths of the three external sides.
The horizontal side from D to E is 16 units long since |-10-6| = 16. I subtracted the x coordinates of the points and applied absolute value. You could also count out the spaces and you should count 16 spaces from D to E.
Unfortunately, the diagonal lengths aren't as straight forward. We have two options here: The pythagorean theorem, or the distance formula.
I'll go with the distance formula.
Let's find the distance from C to D, aka the length of side CD

Side CD is roughly 9.2195 units long.
Repeat this idea to find the length of CE

Side CE is roughly 7.2801 units long
The perimeter of triangle CDE is approximately...
P = DE+CD+CE
P = 16 + 9.2195 + 7.2801
P = 32.4996
This then rounds to 32.5 units. The answer is choice C.
Answer:
Sine 3 books are for 60-
60/3
Rs20 (per book)
and 5 books for Rs 90-
90/5
Rs18 (per book)
Thus we can save 2Rs and 5 books for Rs 90 iscthe best buy
2/30 in percentage is 6,67%
you must divide first the fraction and multiply by 100
Answer:
It is both a relation and a function.
Step-by-step explanation:
Keith collected the names and ages of all of his classmates and organized them in the ordered pair (name, age).
Here, if we consider the name as the input and age is the output, then each and every different input there is a single output.
Because a single person can not have more than one age.
Therefore, it is both a relation and a function. (Answer)
100% of her middle school class = 56
200% of her middle school class = 112 (56 x 2)
25% of her middle school class = 14 (56/4)
225% of her middle school class = 126 (112 + 14)
There are 126 students in her high school class.
