Answer:
5
Step-by-step explanation:
44 - 29 = 15
15 \ 3 = 5
D. (I used 3.14 as pi so my answer was a little off so I just went with the one closest to my answer)
P=2L+2W
L=3+w
24=2x(3+w)+2w
24=6+2w+2w
24=6+4w
24-6=4w
18=4w
4 and 1/2 = 2
Answer:

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.
