Answer:
10⁴
Step-by-step explanation:
10 is repeated 4 times, so your exponent would be 4 with a base of 10.
Answer:
b=√3
a=2
Step-by-step explanation:
Since you are given one side and an angle, you can immediately think of using cos, sin, and tan
When solving for b, you would set up your equation with tan30=1/b since tangent is opposite/adjacent
Next for a, you would solve for sin30=1/a since sine is opposite/hypotenuse
Hope this helps! :)

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.
Grace can just fold the string in half, making two pieces. You collect both pieces and cut half of each string to create 4 pieces. This is essentially fractions.
