For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9
Answer:
x = -3
Step-by-step explanation:

5x+3x^4+15-7x^3
In standard form:3x^4-7x^3+5x+15
Degree:quartic i believe
# of terms:polynimial or 4 terms
8x - (5x + 4) ≥ -31
8x -5x - 4 ≥ -31
3x ≥ -31 + 4
3x ≥ -27
x ≥ - 9
Answer: a numbe line with a circle on - 9 and shading to the left.
Because that drawing represents the number that are less or equel than -9 and the answer is the numbers greater or equal than -9.
Since the only difference in the two meals is one egg mcmuffin, then the difference in the calorie count has to be due to the mcmuffin. So
750 - 450 = 300 calories for an egg mcmuffin.
Jack's egg mcmuffin and hashbrowns totaled 450 calories. Since we know that an egg mcmuffin is 300 calories, then the hashbrowns have to be
450 - 300 = 150 calories
