There is now 1/4 or half a liter left of juice still.
You had mistakes, so I did all of them.
9) -6(1 + 11b) = -6 - 66b
10) -10(a - 5) = -10a + 50
11) -3(1 + 2v) = -3 - 6v
12)-4(3x + 2) = -12x - 8
13) (3 - 7k)*-2 = -2 * (3 - 7k) = -6 + 14k
14) -20(8x + 20) = -160x - 400
15) (7 + 19b)*-15 = -15(7 + 19b) = -105 - 285b
16) (x + 1) * 14 = 14(x + 1) = 14x + 14
Level, x 1 0.8 0.65
time, y 0 1 2
The graph is not a straight line, it is curved. You can observe this only if you include the point (1,0), which is the level at the begining (100%)
The y - intercept is the full level, at the beginning of the experiment.
Solution :
We know that,
- Sum of the measures of all exterior angles = 360°
Measure of each exterior angle = 45°
- The number of sides of the polygon = 360°/45° = 8 .
Hence, the number of sides of the polygon is 8.
As, each exterior angle is 45° ,
Therefore,
- The measure of each interior angle = 180° – 45° = 135°
