The SAS congruence is basically:
S- side
A- angle
S - side
If two triangles have two congruent sides and share one angle (or have one angle in between), then it (the triangles) are considered congruent.
Kenny can buy 15 t shirts and 3 sweatshirts.
Step-by-step explanation:
Given,
Number of members = 18
Cost of each t shirt = $9
Cost of each sweatshirt = $15
Money = $180
Let,
x be the number of t shirts
y be the number of sweatshirts
According to given statement;
x+y=18 Eqn 1
9x+15y=180 Eqn 2
Multiplying Eqn 1 by 9
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 6
Putting y=3 in Eqn 1
Kenny can buy 15 t shirts and 3 sweatshirts.

Answer:
The probability that none of the $100 bills are selected is 79.6%.
Step-by-step explanation:
The urn contains forty $1 bills and ten $100 bills. This gives a total of 50 bills in the urn.
To draw 3 dollar bills one at a time out of an urn, the probability of not selecting a $100 bill, decreases with each selection.
And the probability of not selecting a $100 bill is the probability of selecting a $1 bill in the first selection = 80% (40/50 x 100).
The probability of selecting a $1 bill the second time = 79.6% (39/49).
The probability of selecting a $1 bill the third time = 79.2% (38/48).
The sum of the probabilities divided by 3 = 79.6% (238.8/3)
b) Probability arises when there is a chance that an event may occur from a set of events that could have occurred. It is based on an estimate that one event happens when all the events in the set are given no less equal chance.
