I would first suggest turning them all to one thing, like all decimals, or fractions. I chose decimals.
5.2, -5.6, 3.9, √21. To solve the square root, you have to simplify it. There is the square root of 3, times the square root of 7 which gets 21. These can't be simplified, so we can't simplify through that. But, the closest whole number that is a square root is 16. You can check by multiplying the same number together twice. Doing this will get you about 4.58
5.2, -5.6, 3.9, and ≈ 4.58. This is a simple ordering problem now.
It ends up as -5.6, 3 9/10, √21, 5.2
There are 2 decimals, one negative. There is one square root, and one mixed number. The square root is an infinite decimal when simplified

Answer:
800
Step-by-step explanation:
Find the area of everything first.
30 times 38 = 1140. ( This would be if everything was shaded)
Next, find the area of the mini square.
To do that, calculate the length first.
30-7-6= Length= 17
20 times 17 = 340
1140-340= 800
Answer:
7 people
Step-by-step explanation:
Start with $160. and subtract $12 for parking because you have to pay that no matter how many people you buy tickets for.
160-12=148
Now you can see how many tickets you can buy with $148 by dividing by the price of the ticket which is $20.50
148/20.5=7.21951219512
You can buy 7 tickets
if you do the math, there is $4.50 leftover
