In both cases,

(as a consequence of the interesecting secant-tangent theorem)
So we have
10.





(omit the negative solution because that would make at least one of AB or AD have negative length)
11.




(again, omit the solutions that would give a negative length for either AB or AD)
Answer:
T = 7.5
Step-by-step explanation:
One table = 4 students
? table = 30 students
To get the answer we criss-cross
30 * 1 = 4T(amount of table)
4T = 30
T = 30/4
T = 7.5
There should be 8 tables but the last table has 2 people sitting on it rather than 4.
Answer:
y intercept: 1
slope: -2
equation: y=-2x+1
Step-by-step explanation:
Answer:
they payed 3.825 each
Step-by-step explanation:
15% of 51 is 7.65 so you divide that by two and get 3.825
