Three tennis balls have the same mass. If the total mass of the 3 balls is 6310 grams, what is the mass of 1 ball?(1 point) Responses 2310 grams 2 Start Fraction 3 over 10 End Fraction grams 18910 grams 18 Start Fraction 9 over 10 End Fraction grams 10189 grams Start Fraction 10 over 189 End Fraction grams 2110 grams
To find the mass of one ball, we divide the total mass of the three balls by 3.
6310 grams ÷ 3 = 2103.33 grams
Rounded to the nearest gram, the mass of one ball is 2100 grams.
Therefore, the correct answer is 2110 grams.
Noel has been working on making handmade birthday cards for 1112 hour. If each card takes 16 hour to make, how many cards did he make?(1 point) Responses 15 card Start Fraction 1 over 5 End Fraction card 512 cards 5 Start Fraction 1 over 2 End Fraction cards 56 card Start Fraction 5 over 6 End Fraction card 5 cards
To find the number of cards Noel made, we divide the total hours he worked by the number of hours it takes to make one card.
1112 hours ÷ 16 hours/card = 69.5 cards
Since we cannot have half of a card, we round down to the nearest whole number.
Noel made 69 cards.
Therefore, the correct answer is 69 cards.
