Answer:

The three digit number will be 254 or 344.            

Step-by-step explanation:

Given : When this 3-digit number is rounded up to the nearest hundred, it rounds to 300. The digit in the ones place is 4. The sum of the digits in the 3-digit number is 11.

To find : What is the number?

Solution :

There is a three-digit number.

When this 3-digit number is rounded up to the nearest hundred, it rounds to 300.

i.e. At hundredth place it can be either 2 or 3.

The digit in the ones place is 4.

The sum of the digits in the 3-digit number is 11.

Taking cases :

1) When digit at hundredth place is 2.

The digit in the ones place is 4.

So, The digit at tenth place is 11-4-2=5

The number form will be 254.

2) When digit at hundredth place is 3.

The digit in the ones place is 4.

So, The digit at tenth place is 11-4-3=4

The number form will be 344.

Rosa believes she can use a division expression to find the cost per pound of ground beef when 1 pound sells for $4. Which state
DiKsa [7]

Answer:

Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word.

Step-by-step explanation:

Given that

1 pound of ground beef sells for $4.

To find the cost per pound:

We need to divide the cost with the number of pounds.

i.e.

\text{Cost per pound = }\dfrac{\text{Total Cost}}{\text{Number of pounds}}

If 'Number of pounds' = 1, then cost per pound = Total Cost

Therefore, the above division expression can be used to find the Cost pound.

Putting the values given to find the 'Cost per pound':

\text{Cost per pound = }\dfrac{\$4}{1} = \$4

Therefore, Rosa's belief is correct that, a division expression can be used.

The correct answer is:

Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word.
