A
The volume (V) of a pyramid is found using the formula
V = × area of base × height(h)
area of base = 9² = 81 ← area of a square, hence
324 = × 81 × h = 27h ( divide both sides by 27 )
h = = 12 → A

Answer:
No, they will need an additional £34 to stay the planned 10 nights.
Step-by-step explanation:
Attached screenshot of a spreadsheet.
The cost for 10 nights for the 2 people is £100.
The tent site rental (over 10m^2) for 10 nights is £150.
Savings for the two over the 9 weeks is £216.
They will need an additional £34 to camp as planned.
I suggest fibbing about the extra 0.5m^2 needed for the tent site. That will reduce the bill by £30, so they are only £4 short. Time to make a couple of friends.
Answer:
Option B,C and E are solution to given inequality
Step-by-step explanation:
We need to check which ordered pairs from given options satisfy the inequality
Ordered pairs are solutions to inequality if they satisfy the inequality
Checking each options by pitting values of x and y in given inequality
A ) (1, -5)
So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.
B) (-3, - 2)
So, this ordered pair is solution of inequality as it satisfies the inequality.
C) (0, -9)
So, this ordered pair is solution of inequality as it satisfies the inequality.
D) (2, -1)
So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.
E) (5, 4)
So, this ordered pair is solution of inequality as it satisfies the inequality.
So, Option B,C and E are solution to given inequality
