Answer:
21
Step-by-step explanation:
Since the order of the essays isn't important, the number of ways you can choose 2 from 7 is:
₇C₂ = 7! / (2! (7−2)!)
₇C₂ = 7! / (2! 5!)
₇C₂ = 7×6×5! / (2×1 × 5!)
₇C₂ = 7×6 / 2
₇C₂ = 21
Answer:
Take this algebraic expression in pieces:
5 times x:
5x
The difference of 5x and 4 means we subtract 4 from 5x:
5x - 4
We want to cube this difference, which means we raise the difference to the power of 3.
(5x - 4)^3
Step-by-step explanation:
Answer:
The percent of decrease can be calculated with this formula:
(Original value - New Value)/(Original Value)
In this case, the original value is 117 and the new value is 91.
So the percent of decrease is 26/117, or about 22%.
Hope this helps!
Answer:
c
Step-by-step explanation:
The identified for the construction is the endpoint of rays BA and BC option (C) is correct.
<h3>What is an angle?</h3>
When two lines or rays converge at the same point, the measurement between them is called a "Angle."
It is given that:
Angle ABC has point E on ray BA and point D on ray BC.
Points E and D are equidistant from point B.
The ED distance because if the distance between E and D is even slightly different, the entire angle ABC will vary.
Thus, the identified for the construction is the endpoint of rays BA and BC option (C) is correct.
