Anastaziya [24]

Total mass in grams of the carton and the 4 boxes is 18.5 kg .

Step-by-step explanation:

Here we have , Monica has 4 boxes to place in an empty carton the mass of each box is 4.5 kilograms the mass of the carton is 500 grams.

We need to find the total mass in grams of the carton and the 4 boxes . Let's find out:

Total mass = Mass of 4 boxes + Mass of empty carton

Mass of 1 box = 4.5 kg

Mass of 4 boxes = $4.5(4) = 18kg$

Mass of 4 boxes = $18kg$

Mass of empty carton = $500g$ = 0.5 kg

⇒ Total mass = Mass of 4 boxes + Mass of empty carton

⇒ Total mass = $18 + 0.5$

⇒ Total mass = $18.5\ kg$

Therefore, total mass in grams of the carton and the 4 boxes is 18.5 kg.

Look at the following numbers and their labels A,B,C, and D.

zhuklara [117]

Answer:

Third option listed

Step-by-step explanation:

To find where to plot each letter, we have to round to the nearest ten--called the tens place.

321 [tens place underlined]

when rounding to a certain place value [like tens, hundreds, etc.], we round the digit by rounding the digit to the right of it.

If the digit to the right (in this case, the ones place ; 321)

is less than 5, we keep the digit in the tens place the same (and write a 0 in the ones place)

if the digit is greater than or equal to 5, we round the digit up (increase it by 1, and then write 0 in ones place)

so, here are the letters rounded:

A 269 = 270 [9 is greater than 5]

B 317 = 320 [7 is greater than 5]

C 298 = 300 [8 is greater than 5, and we carry the 1 from the tens place]

D 327 = 330 [7 is greater than 5]

Now, to find each value on the number line, we can look for that number [below each tick/mark]

So, the third option listed is correct

hope this helps!!
