Angle e will be 132 because it is a vertical angle with 132, and they are congruent. Angle d will be 48 because it must add up to 180, and 180-132=48. Angle c will be 42 because that and 138 are supplementary angles, and they need to add up to 180, so 180-138=42. Angle b will be 90 because it is across from the 90 degree angle, and so they are congruent. And angle a will be 90 as well because angles a and b are supplementary angles, so they need to add up to be 180 degrees. I hope that helps! :)

Answer is 2 terms
If 2 boxes remain empty, it means that we put all three balls in one single box.
Suppose the full box is box number 1. For each ball, we have three choices - we may put it in box number 1, 2 or 3. This means that each box has a 1/3 chance of receiving each ball.
So:
- we choose box 1 for ball 1 - that's a 1/3 chance
- we choose box 1 for ball 2 - that's a 1/3 chance
- we choose box 1 for ball 3 - that's a 1/3 chance
So, the probability of putting all balls in box 1 is
But this is the probability of putting all ballx in box 1, and you can repeat this logic for box 2 and 3.
So, the probability of putting all balls in one single box is 1/27 for each box, for a total of
Answer:
there are thirty kids in the class
Step-by-step explanation:
there are two boys to three girls so 18 divided by 3 is 6. 2 times 6 is 12. 12 plus 18 is 30.
(1.3 x 10^-4) n = (2.6 x 10^12)
n = (2.6 x 10^12) / (1.3 x 10^-4)
n = 2 x 10^16
