Let L represent the length of the rectangle.
Let W represent the length of the rectangle.
We know that the perimeter of the rectangle is 48cm, which is equal to 2(L + W).
Therefore, L + W = 24cm.
We also know that L = 2W.
Hence, Length = 16cm and Width = 8cm.

Step-by-step explanation:
The Binomial Coefficient can be used to calculate the number of ways objects can be arranged.
<u>Binomial Coefficient</u>

The exclamation mark "!" placed after a number means factorial and indicates to multiply all whole numbers from the given number down to 1.
Example: 4! = 4 × 3 × 2 × 1
The Binomial Coefficient gives us the number of ways of picking "r" unordered outcomes from "n" possibilities.
As there are 8 friends ⇒ n = 8.
As each car takes 4 friends ⇒ r = 4.
Substitute these values into the formula:

Answer:
1.47 mm
Step-by-step explanation:
In week 1 there was 2.6 mm
In week 4 there was 4.07
You want to find the difference of week 1 and 4 meaning you have to subtract week 4's value from week 1's to find how much more rain there was in week 4 than week 1
You would do 4.07-2.6
This is equal to 1.47
THEREFORE there was 1.47 mm more rain in week 4 than week 1
