Any equation where you have a y and a x
The two figures are congruent because the side lengths are the same, therefore making the angle measures the same.
Answer: $112, 16 trips
Step-by-step explanation:
You would plug 9 into the equation for t. Then for the total amount until she was out of money you would divide 256 (her total amount of money) by 16 (the toll cost per trip)
The possible combinations are:
1,9
2,8
3,7
4,6
9,1
8,2
7,3
6,4
Total straws: 9
Probability of first being 1: 1/9
Probability of second being 9: 1/8
Probability of both: 1/9 x 1/8 = 1/72
This will be multiplied by 8 as there are 8 possible combinations:
8 x 1/72
= 8/72
= 1/9
