Answer:
9 blue marbles
Step-by-step explanation:
4 : 3 ratio
12 : x
12 / 4 = 3
4 × 3 : 3 × 3
12 : 9
Let b and h represent the length of the side of the base and the slant height, respectively. Then the total surface area is
A = b² + 4*(1/2)bh
A = b² +2bh
Substituting the given numbers, you have
336 = 12² +2·12·h
192 = 24h . . . . . . . . . subtract 12² = 144
8 = h . . . . . . . . . . . . . divide by 24
The slant height is 8 inches.
In order to get the answer to this question you will have to use PEMDAS and solve.

Using PEMDAS:










Therefore your answer is "-103."
Hope this helps.
Answer:
382000
Step-by-step explanation:
-126 = -34 + 2x is the equation you would use. solve for x, which would be -46. it would take 46 minutes for the diver to reach 126 feet below sea level.
