Actually that answer is wrong. You need to divide not add. The answer is -3 b/c 51 divide -17=-3. You divide because theres a variable. If no variable is present then it would be subtracting
Option B: 36 : 1 is the ratio of the surface area of Solid A to Solid B
Explanation:
Given that the Solid A is similar to Solid B.
The volume of Solid A is 3240 m³
The volume of Solid B is 15 m³
We need to find the ratio of the surface area of Solid A to Solid B.
Thus, we have,
Dividing the terms, we get,
Taking cube root, we get,
Squaring the ratios, we get,
Thus, the ratio of the surface area of Solid A to Solid B is 36 : 1
Hence, Option B is the correct answer.
You have 3hours 25seconds left to assemble the machine.
By process of elimination and plugging in the math we can say that Jack earns 8.25 an hour by multiplying 2*8.25=16.50. Isa must then earn 9.50, therefore she earns a greater hourly pay then Jack as a result
Yes, this is a random sample because he chose a random group of kids to answer. However, this is also a terrible sample because it is small and doesn't include a wide variety of people. You could make the case to say that it isn't a random sample, but I believe the right answer is that it is.
