Order of operations:

2 • {390 – [5 • (10 – 4 ÷ 2)] + 15} • 2

so PEMDAS

the order of simplification/operation is
parenthaseese
exponents
multiplication or division whichever comes first
addition or subtraction whichever comes first

so we work the parenthasees inside to out

inside parenthaseese=(10-4/2)
so no exponents so skip
there's division so we do that
4/2=2/1=2
then we have
(10-2)
subtraction
10-2=8
(8)
next parenthaseese/bracket
[5 times (8)+15]
multiplication
5 times 8=40
[40]
other brackets
{390-[40]+15}
subtraction
390-40=350
{350+15}
350+15=365
outside
2 times {365} times 2
multiplication
2 times 365=730
730 times 2=1460

2 * {390 - [ 5 *( 10 - 4 / 2)] + 15} * 2.
2*{390-[5*(8)]+15}*2
2*{390-[40]+15}*2
2*{390[-40]+15}*2
2* {-135,585}*2
{-271170}*2
-542,340

Step-by-step explanation:

Rupert drove home at an average rate of 58 miles per hour. Find his rate in feet per second.

To find this, you must first multiply 58 by the number of feet in a mile, 5280, to get a total number of feet. This comes out to 306,240 feet per hour. Next, you divide this by 60, since there are 60 minutes per hour, to find the rate of feet per minute, which comes out to 5,104 feet per minute. Finally, you divide this number by 60 again, since there are 60 seconds per minute, to get the final answer of a rate of about 85.0666... feet per second.

Step-by-step explanation:

What is 284 rounded to the nearest hundred

284 rounded to the nearest hundred is 300.

### What is a place value?

Place value, which is related to a digit's location in a number, is the amount that each digit is worth.

Given:

The number is 284.

To round the number to the nearest hundred:

The digit in the hundredth place is 8.

And 8 > 4.

So, the number left to the number 2 will increase by 1.

And the number right next to 8 will become zero.

So, the value of 2 becomes 2 + 1,

and the rest number becomes zero.

So, 284 rounded to the nearest hundred is 300.

Therefore, the result is 300.
