Cheryl has to pay a total charge of £100.98.
Step-by-step explanation:
Step 1; A ticket for an adult costs £12 and a ticket for a child costs £6. So for 6 adults and 3 children, the ticket price is
Ticket price= 6 × £12 + 3 × £6 = £72 + £18 = £90.
So the ticket prices alone are £90. A booking fee of 10% is added to this £90.
Booking fee = 10% of £90 = £9.
Ticket price inclusive of booking fee = £90 + £9 = £99.
Step 2; Cheryl pays by credit card so an additional 2% is added to the final price i.e. 2% is added to the £99.
Credit card charges = 2% × £99 = £1.98
Final booking fee = £99 + £1.98 = £100.98.
So buying the tickets with credit card, Cheryl pays £100.98 to buy the tickets.
Answer: f(6) = (6)2 + 1 = 36 + 1 = 37
If we wanted to find and expression for f(g(x)) we could plug in g(x), which is "x - 4" into the function f(x) wherever we see an "x". So:
f(x) = x2 + 1
f(g(x)) = (x - 4)2 + 1 because g(x) is "x - 4"
Step-by-step explanation:
the probabiltity is:
outcome/total possible outcomes
therefore, 100/101
DOB
that is from 55 to 145
acute means angle is less than 90 degrees
right means equal to 90
obtuse means greater than 90
so
55 to 145
145-55=90
it is right angle
H/1000 = tan(65°)
h = 1000*tan(65°) ≈ 2145 . . . . ft
The helicopter is about 2145 ft high.
