Answer:
$343
Step-by-step explanation:
To get 30% of 490 we divide 30% by 1
30% ÷ 1 = 147
Now, we subtract 490 by 147
490 - 147 = 343
Answer:
A. 2 (0)=0
B. 2 (2)=4
Step-by-step explanation:
You have to multiply the X numbers by 2 for example 2x , x=2 , 2x2=4
Note that
108° = 90° + 18°
so
sin(108°) = sin(90° + 18°) = sin(90°) cos(18°) + cos(90°) sin(18°) = cos(18°)
Then
sin²(108°) + sin²(18°) = cos²(18°) + sin²(18°) = 1
by the Pythagorean identity.
Answer: Hi! I would say it is D because the other answers really don’t make sense. And the passages said that they were rated low for air quality.

I hope this helps!
Step-by-step explanation:
normally, if we have the gradient (or slope of inclination or change rate) and a point, we start using the point-slope form :
y - y1 = a(x - x1)
with (x1, y1) being a point on the line, and a being the slope of gradient (or ... however you want to call it).
y - 1 = 2(x - 2) = 2x - 4
y + 3 = 2x
2x - y = 3
