The answer would be: 67.89 x 10^6
The rules of significant numbers used:
- any non-zero digit is significant
- zeroes that are in the right side of the non-zero whole number would not be significant
Thus, only the significant numbers left in the equation:
67.89 x 10^6
Answer:
πx² -6πx + 9π
or
π(x² - 6x + 9)
Step-by-step explanation:
area = πr² = π(x-3)² = π(x² - 6x + 9) = πx² - 6πx + 9π
- Let r represent Rick’s height.
- Therefore, the quotient of Rick’s height and 4

- Fred is 5 inches shorter than the quotient of Rick’s height and 4.
- Therefore, an expression that represents Fred’s height is

Answer:

Hope you could get an idea from here.
Doubt clarification - use comment section.
Answer:
C
Step-by-step explanation:
C is the correct answer because the other 3 points are not correct when you put the numbers into the equation.
y = 16 + 0.5x
20 = 16 + 0.5(8)
20 = 20
The expression is consistent witch means and can keep going a long time the answer is x0x0
