Answer:
- Robert is wrong, the correct answer is 4 times greater
Step-by-step explanation:
Area is the product of two dimensions.
If each dimension is doubled, then the area becomes 2*2 = 4 times greater.
If each face is 4 times greater, then their sum will be 4 times greater.
The sum of the faces is the total surface area, therefore the B's surface area is 4 times as great as A's surface area.
Answer:
1:4
Step-by-step explanation:
There are only two colours available, red and green. We know that there are 11 red marbles and 55 marbles altogether, so the number of green marbles must be 55 - 11, or 44. That means that the ratio of red to green marbles is 11:44, or 1:4.
The answer is the third one
Kenilworth = 9
Total = 40
Divide 9 by 40 to get the probability
9 ÷ 40 = 9/40
Your answer is 9/40 (22.5%)
Hope this helps :)
