If you would like to calculate 57 divided by 8, you can do this using the following steps:
57 divided by 8:
57 / 8 = 7 1/8 = 7.125
The correct result would be 7 1/8 or 7.125.
Use the Cosine Rule
q^2 = 20^2 + 30^2 - 2^20*30 cos 15
= 140.89
so q = sqrt 140.89 = 11.9 (answer)
Answer: "Point A is a solution because it is in the shaded area
Step-by-step explanation:
When we have an inequality like the one shown in the graph, the shaded area represents the possible solutions to the inequality.
If we have a dashed line, then the points in the line are not solutions (this is the case of the symbols > and < )
If the line is solid, then the points of the line are solutions (this is the case of the symbols ≤ and ≥)
In the graph we can see that point A is inside the shaded area, then point A is a solution.
Then the correct option is:
"Point A is a solution because it is in the shaded area"
