Answer:
The answer is $20.21
Step-by-step explanation:
So first you find the subtotal cost of the lunches. Each lunch costs $20, so that would be $40 in total.
Now you find the total cost.
She has to pay 5% sales tax so to find the total, you have to multiply 40 by 0.05. That gives you a total of $2. Then you add that to your $40 to get $42.
Now for the tip.
It says to find 10% of 20, so you have to multiply 20 by 0.1. That equals 0.208. Then you add that to 20 to get 20.208.
If you round off, you get a total of $20.21

Step-by-step explanation:
The side lengths on the new dilated rectangle will be 30cm and 16cm
<h3>How to calculate dilation</h3>
Given the following parameters
- Length = 8cm
- Breadth = 15cm
If the length and breadth are dilated by a factor of 2, hence the new dimansion will be:
New length = 2(15) =30cm
New width =2(8) = 16cm
Hence the side lengths on the new dilated rectangle will be 30cm and 16cm

Answer:
The answer is 1/12
Step-by-step explanation:
For each tank just divide the number of L by the number of fish to get the volume or fish.
For tank A it is 40/5=8, for tank B it is 100/12=8.3, and for tank C it is 180/23=7.8.
If you number them least to greatest, it is (tank C, tank A, tank B)
