The Cartoon lasts 1080 seconds.
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A cartoon lasts 18 minutes.
We know, 1 minute = 60 seconds
So, 18 minutes= 60 x 18
= 1080 seconds
Hence, the cartoon lasts 1080 seconds.

Answer:
20 ≤ L + W ≤ 40
Step-by-step explanation:
[answer is marked by ** symbol]
The perimeter (P) of a rectangle is given by the formula:
P = 2L + 2W
In this case, you want to spend between $100 and $200 on fencing, and the cost is $2.50 per foot. So, you can write the cost equation as:
Cost = 2.50 (2L + 2W)
Now, you want the cost to be between $100 and $200, which leads to a compound inequality:
$100 ≤ 2.50 (2L + 2W) ≤ $200
Now, divide each part of the compound inequality by 2.50 to isolate the expression (2L + 2W):
$100 / 2.50 ≤ 2L + 2W ≤ $200 / 2.50
40 ≤ 2L + 2W ≤ 80
Now, divide each part by 2 to find L + W:
**20 ≤ L + W ≤ 40
**This compound inequality models the possible length of the dog run. It states that the length plus the width of the dog run must be between 20 feet and 40 feet to stay within the budget of $100 to $200 for fencing.

X = 220 rabbits
Answer:
4+0.75(m-5) ≤ 10
Step-by-step explanation:
We start out with 4, since the car wash charges $4 for the first 5 minutes. We add to this the cost based on the minutes over 5 that he used the car wash.
Since m is the number of minutes, we first subtract 5 from this. This is because the first 5 minutes are included in the initial $4. Since each minute past 5 costs $0.75, we multiply m-5 by 0.75:
0.75(m-5)
Together this gives us
4+0.75(m-5)
He only has $10 to spend. This means he must spend less than or equal to $10; this gives us
4+0.75(m-5) ≤ 10
