Answer:
The answer is below
Step-by-step explanation:
A tangent is a line which touches a circle at one point. The angle between a tangent and a circle is 90°.
The two tangent theorem states that tangent that meet at the same point are equal in length.
Therefore:
CD = c + d
but c = 5.1, hence:
CD = 5.1 + d
12.1 = 5.1 + d
d = 7
AD = a + d; but AD = 12.2, d = 7
12.2 = a + 7
a = 5.2
AB = a + b; but b = 3.3
AB = 5.2 + 3.3 = 8.5
BC = b + c = 3.3 + 5.1 = 8.4
Perimeter of ABCD = AB + BC + CD + AD = 8.5 + 8.4 + 12.1 + 12.2 = 41.2
Answer:
Step-by-step explanation:
GIVEN: A hotel charges a annual fee plus an additional
for each night you stay there.
TO FIND: average cost per night if you stay at the hotel for nights.
SOLUTION:
Annual fee charged by hotel
amount charged each night we stay there
Total number of nights we stay
Total amount paid for nights
Total amount paid
average cost per night
putting values,
average cost per night
Hence average cost per night if we stay at hotel for days is
