Answer:

800 to the nearest hundred

Step-by-step explanation:

To Estimate the sum of 405 and 385, we will add 405 together with 385 I.e 405+385 to get 790.

Rounding 790 to a hundred is 800 since the second place value in 790 which is '9' is greater than 5, we will add 1 to the first place which is 7 to give us 8. This will change the second place value to '0' which make the value of 790 to be 800 to a hundred.

Note that 1 can only be added to a preceding value of a number if the succeeding value is greater than 5.

Answer:

Step-by-step explanation:

So if u divide each number of players by the number of winners each time u come out with 3.something

So if ur looking for 100 players ud want the number of winners divided by that to equal 3.something

So 100/33=3.something

Plus every answer goes up so u also know its true

Carl earns $5.25 per hour walking his neighbors dogs. He walks them 2/6 of an hour in the morning and 1/2 of an hour in the afte

DIA [1.3K]

2/6 = 1/3 = 20 minutes
1/2 = 30 minutes
20 + 30 = 50 minutes

50 minutes x 7 = 350 minutes = 5 hours and 50 minutes
5 x $5.25 = $26.25
50 minutes = 5/6
5/6 of $5.25 = 4.375

Add $26.25 to the total for 50 minutes to get your answer. :)
