Answer:
We conclude that Linda is right, and that it really is bad because it's a 25% increase.
Step-by-step explanation:
Harry notes that the state sales tax went from 2% to 2.5%.
Therefore, we get the following proportion.
We calculate:
2% : 100% = 2.5% : x
2x=100 · 2.5
2x=250
x=125%
So, we conclude it's a 125% - 100% = 25% increase.
We conclude that Linda is right, and that it really is bad because it's a 25% increase.
Area of the window:
A ( window ) = 16 · 100 + 1/2 · 20² π = 1600 + 200 π = 2,228
A ( window + shade ) = 48 · 40 + 1/2 · 24² π = 2,824.32
A ( shade ) = 2,824.32 - 2,228 = 596.32 ≈ 596 in²
Answer:
Area of the shade is 596 in².

We will use additional formula:
sin ( 90°+ theta ) = sin 90° * cos(theta) + cos 90° * sin(theta)=
= 1 * cos(theta) + 0 * sin(theta)= cos (theta) It is proved.
Answer:
y < -2
Step-by-step explanation:
7 - 6y > 19
Subtract 7 from each side
7-7 - 6y > 19-7
-6y > 12
Divide each side by -6. remembering to flip the inequality
-6y/-6 < 12/-6
y < -2
