2.67 - 1.84 = 0.83
Tina added 0.83 liters of olive oil.
Answer:
The answer is Angle 5 duhhhhh
The polygon have 59 sides.
Solution:
Sum of the measure of interior angle of the polygon = 10260°
Interior angle theorem of polygon,
<em>The sum of measure of interior angles of a polygon is (n – 2) × 180°.</em>
By this theorem,
(n – 2) × 180° = 10260°
Divide by 180° on both sides.
Add 2 on both sides, we get
n – 2 + 2 = 57 + 2
n = 59
Hence the polygon have 59 sides.
First you would simplify what's in the square root, to get root 20. If you want the exact number, and not the approximation, you would take out whatever squares are in that number (20=2*2*5) so your answer is 2root5.
However, if you want the approximation, simply plug it into your calculator and get 4.18154055.
1. The absolute value function takes any quantity and makes it positive, so it's impossible to have |3x + 7| < 0. There is no solution.
2. If b + 5 ≥ 0, then
|b + 5| = b + 5 = 2b - 9
b = 14
Otherwise, if b + 5 < 0, then
|b + 5| = -(b + 5) = 2b - 9
-b - 5 = 2b - 9
3b = -4
b = -4/3
However, this second solution is extraneous, since the left side is positive,
|-4/3 + 5| > 0
while the right side is negative,
2•(-4/3) - 9 = -8/3 - 9 < 0
