C:5
just divide 445 by 89 and you get 5
In rounding, a number must be 5 or more to round up, and 4 or less to round down.
To round up to 4.26 you would need a number between 4.255 and 4.264
4.258 and 4.261 are two examples
Answer:
Explanation:
You are comparing irrational numbers.
By inspection, i.e. at first sight you can only compare 
because they have the same radicand.
You can order: 
You can introduce the 2 inside the radical by squaring it:
Since 5 is between 3 and 12, you can order:
Which is:
You must know that π ≈ 3.14.
5 is less than 9 and the square root of 9 is 3; hence, 
and 
Now you must determine whether π is less than or greater than 
Using a calculator or probing numbers between 3 and 4 you get 
Hence, the complete order is:
Answer:
103.
Step-by-step explanation:
The initial budget is $5,323 and has already spent $2,748, so the remain budget is $2,575. If the meal price per guest is $25, so:
$2,575 / $25 = 103
She can invite up to 103 guests.
Let us assume the width of the rectangle = x cm
Then
The length of the rectangle = (x + 4) cm
It is already given that
Perimeter of the rectangle = 80 cm
Now we also know the formula for perimeter of a rectangle
Perimeter = 2 ( length + width)
80 = 2 (x + 4 + x)
80 = 2 (2x + 4)
80/2 = 2x + 4
40 = 2x + 4
Dividing both sides by 2 we get
20 = x + 2
20 -2 = x
x = 18
Then
Width of the rectangle = 18 cm
Length of the rectangle = (18 + 4) cm
= 22 cm
So the rectangle has a length of 22 cm and a width of 18 cm.
