Answer:the answer would be B
Step-by-step explanation:
the operation is +
Nothing "weighs" 56.7 grams. "Gram" is a unit of mass, not force or weight.
On Earth, 28.35 grams of mass weigh about 1 ounce .
1 dozen of anything = 12 of them
If each tennis ball has 56.7 grams of mass, then a dozen of them
have
(12) x (56.7) = 680.4 grams of mass .
Their weight is (680.4 grams) x (1 ounce / 28.35 grams) =
(680.4 / 28.35) = 24 ounces.
That's 1.5 pounds.
Answer:
14 squares
Step-by-step explanation:
1. We know if the mosaic is a square shape, all sides are the same length and consist of the same amount of squares
2. Area is L×W, so in this case A×A=196
3. We can test this by replacing A with 14 and seeing if the answer is correct.
4. 14×14=196 is true
This can also be done by finding the square root of 196.
The total = 3.5 * 4 = 14
(14 + x) / 5 = 4
14 + x = 20
x = 6
