4 0

Answer:

about 0.196  

Step-by-step explanation:

4 + 18 + 10 + 8 = 40, this means that the piggy bank has 40 coins in total.  Probability of the FIRST coin being a dime is 18/40 and the probability of the SECOND coin being a dime too is 17/39. To find the answer you would multiply 18/40 x 17/39.

18/40 x 17/39 = 306/1560 = about 0.196  

Hope this helps :D

Answer:

C 109

Step-by-step explanation:

First add all the known angles inside the triangle first to get 109°

Then since all angles in a triangle add to 180°

you take away 109 from 180 so

180-109 which equals 71

Then since all angles on a straight line add up to 180°

you take 71 from 180 so

180-71 = 109

so x = 109°

Help please............

Hello!!

Well, the angles in a triangle must add up to 180 degrees.
So, since one angle is 40 degrees, the other two angles must add up to 140 degrees.
A quick look over the answer choices will show that option C, 35 degrees and 105 degrees, is the only possible answer.

Hope this helps!! Let me know if you have ANY questions.
