first of all we need to know our place values.
4= hundreds
5= tens
5= units/ones
2= tenths
1= hundredths
8= thousandths
7= ten thousandths.
To round a number to the nearest thousandth, look at the next place value to the right (the ten thousandths). If it's 4, or less, just remove all the digits to the right. If it is 5 or greater, add 1 to the digit in the thousandths place and then remove all the digits to the right.
Now to your question; the ten thousandths digit is greater than 5 (7). So we would add 1 to the digit in the thousandths place ( which is 8) then remove all digits to the right.
So our result end up in :
455.219
Please mark as brainliest.
Let a be the amount needed of 70% pure antifreeze, and let b be the amount needed of 95% pure antifreeze.
0.7a + 0.95b = 180 * 0.9 .........(1)
a + b = 180 .............................(2)
b = 180 - a ..............................(3)
Plugging the expression for b in equation (3) into equation (1), we get:
0.7a + 0.95(180 - a) = 162 ......(4)
Solving equation (4) gives the value a = 36, and plugging this value for a into equation (2) we get b = 144.
Amounts needed are therefore 36 gallons of 70% pure antifreeze and 144 gallons of 95% pure antifreeze.

Step-by-step explanation:
- So it takes 5 pounds to make 9 jars of peanut butter and x pounds to make 24 jars of peanut. The equation is written as
5pounds=9 jars
? =24 jars
Then you cross multiply /work it out as
<h3> 5×24÷9 </h3>
And your final answer will be
13 1/3 pounds
