She would get £2.50
4 times 2 is 8
2 times 3 is 6
0.7 times 5 is 3.5
Add them together
Minus it from 20
It equals £2.50
The maximum volume would be when the bottom of the box is a square.
The perimeter of the bottom is 36, so the side of the square would be 36/4 = 9 cm.
Then to find volume multiply the length by the width by the height:
Volume = 9 x 9 x 4 = 324 cm^3
The answer would be a.
Hello there!
12/15 and 8/10 don't have the same value.
Reason:
let's simplify both.
12/3 = 4
15/3 = 5
12/15 = 5/4
8/2 = 4
10/2 = 5
8/10 = 4/5
5/4 is greater than 4/5
5/4 > 4/5
Hope i helped!
Let me know if you need anything else!

i was going to answer but siomeome beat me lol but hdjwStep-by-step explanation:
Answer:
3rd option
Step-by-step explanation:
Given z is inversely proportional to (y - 2)² then the equation relating them is
z = 
← k is the constant of proportion
To find k use the condition when y = 5, z = 9 , then
9 = 
= 
= 
( multiply both sides by 9 )
81 = k
z = 
← equation of proportion
