Answer:
The answer is d.60 degrees
Step-by-step explanation:
When you add up all the angles in a triangle, you get the sum of 180°.
Since this is an equilateral triangle, all of the angles will be 60° because 180/3=60
9 people would want Red pens, and 27 would want Blue pens. You can solve this by first adding the two numbers together to get 12. Then, you would divide 48 by the 12 you just got to get 3. You can then multiply 3 and 9 by 3 to get how many of each color you need to get.

Answer:
D
Step-by-step explanation:
For a sequence to be an arithmetic sequence, it must have a common difference. In other words, it must either go down by the same number or up by the same number.
Let's look at the choices:
A. {-10,5,-2.5,1.25,...}
-10 to 5, that went up by 15. It has to keep going up by 15 to be arithmetic. However 5+15 is not -2.5 so it isn't arithmetic.
B. {100,20,4,0.8,...}
100 to 20, that went down by 80. Since 20-80 is not 4, then this sequence is not arithmetic.
C. {1,4,16,48,...}
1 to 4, that went up by 3. 4+3 is not 16 so this is not arithmetic.
D. {-10,-3.5,3,9.5,...}
-10 to -3.5, that went up 6.5.
-3.5+6.5=3
3+6.5=9.5
This is arithmetic. It keeps going up by 6.5.
