Answer:
13,440
Step-by-step explanation:
10 possible digits 0 - 9
5 possible numbers for position 5 (odd digits only)
8 possible numbers for position 1 (cannot be zero or the odd number selected for position 5)
8 possible numbers remain for position 2 (10 minus 2 already selected)
7 possible numbers remain for position 3 (10 minus 3 already selected)
6 possible numbers remain for position 4 (10 minus 4 already selected)
5•8•8•7•6 = 13,440
Answer:
option . D
Step-by-step explanation:
The reason for this is because it is turned around which is able to be turned around and have the same answer in the end.
CommentThe measurement of an arc in degrees is the same as the central angle. We must assume that the central angle is the measurement given.
= 49
To find the next one you need to find the measurement from B to C, the arc that is over 180 degrees. Maybe you could put another letter between B and C so that we could refer to that top arc greater than 180 degrees. Call the point you inserted D.
= 360 - 49 - 107 = 204
=
+
Arc(
ABC) = 204 + 49 = 253
Arc(
BAC) = Arc(BC) + Arc(AB)
Arc(
BAC) = 107 + 49
Arc(
BAC) = 156
Arc(
ACB) = 107 + 204 = 311
Regarding this question it can said that there is nothing special about it. Only thing is converting the word one fifth into the number 1/5 and then multiplying it with the total number of 12000.
One fifth of 12000 = (1/5) * 12000
= 12000/5
= 2400
So 2400 is the one fifth of 12000. Care should be taken while dividing. I hope this is the answer you were looking for and the procedure is perfectly clear to you. In future you can attempt such problems on your own without requiring any kind of outside help. I am glad to have helped you.
Answer: 3 cm
Work Shown:
(1 cm)/(5 m) = (x cm)/(15 m)
1/5 = x/15
1*15 = 5*x ... cross multiply
15 = 5x
5x = 15
x = 15/5
x = 3
The model is 3 cm tall.
