Answer:
1000
Step-by-step explanation:
If the number of protesters per minute remains a constant, then you could write the proportion ...
p/12 = 177/2.1
Multiplying by 12 gives ...
p = 12(177/2.1) ≈ 1011.4
Here, minutes are given to 2 significant figures, and the initial count is given to 3 significant figures. The best you can hope for is that your estimate is good to 3 significant figures:
1010 protesters
It is probably sufficient to report the number to 2 significant figures*:
1000 protesters
_____
* Unfortunately, with a number like 1000, the only way you can tell it has 2 significant figures is to report it as 1.0×10³ or 10. hundreds. The trailing zeros are usually not considered significant.
Answer: 10.0
Step-by-step explanation: In this problem, we are asked to round 10.034 to the nearest tenth. It's important to understand that the tenths place is 1 place to the right of the decimal point. So the digit in the rounding place is 0.
Next, look at the digit to the right of the rounding place which in this case is 3. Since the digit to the right of the rounding place, 3, is less than 5, we round down.
This means that the digit in the rounding place, 0, stays the same and we change all digits to the right of the rounding place to 0.
So 10.034 rounded to the nearest tenth is 10.000 or just 10<em>.</em>0 since we can drop zeroes at the end of a decimal.
Answer:
2x³ - 2x² - 12x
Step-by-step explanation:
2x (x - 3)(x + 2) = (2x² - 6x)(x + 2)
= 2x³ + 4x² - 6x² - 12x
= 2x³ - 2x² - 12x
