Answer:
Option A.
Step-by-step explanation:
The given word is "mathematician".
Here, total number of letter is 13 and
Number of distinct letters = 8
We need to select 2 distinct letters from word "mathematician".
It means we need to select 2 letters from 8 distinct letters.
Total ways 
Therefore, the correct option is A.
Answer:
(C)On a coordinate plane, 2 rays form an angle. One ray sits on the x-axis.
Step-by-step explanation:
In the coordinate plane, an angle is said to be in standard position when its value is stated with respect to the x-axis.
Therefore, for an angle to be in a standard position, one of its rays must be on the x-axis.
From the given options, only Option C has a ray that sits on the x-axis. Therefore, it is the only angle in standard position.
Answer:
The distance between the pair of points is 12.0 (to the nearest tenth)
Step-by-step explanation:
The distance between a pair of points in a coordinate system is found by the formula:
d =
where, the points are:
From the graph,
Substitute the points into the formula:
Answer:
10 degrees
Step-by-step explanation:
The angle between hour and minute hand in 4:20 is 10 degrees. For a minute, the hour hand rotates by 30/60 = 1/2 degrees. hence, for 20 minutes it rotates by an angle of 20*1/2 = 10 degrees.
(Answer: 120) angle EHF = 90 degrees+30 degrees=120 angle
