Answer:16.5
first subtract 5 then divide by 2
43.75 divided by 7 is 6.25, thus your answer is 6.25 hours
All you have to do is this, area = Base * height or B*H so now you all you do is, 90*25 = 2250 then since 10 more yd is put on all you do is 2250 = 1400 yd.
As the sum of the angles of a triangle is 180 degrees, we can find the measure of Angle A.
180 - 102.9 - 18.6 = 58.5
Now that we know angle A, we can use the Law of Sines to find AB. The angle opposite BC is 58.5 degrees, which we found above. The angle opposite AB is angle C, which is 18.6 degrees.
By the Law of Sines,
AB / sin (18.6) = 943 / sin (58.5)
AB / .31896 = 943 / 0.85264
AB / .31896 = 1105.97652 by simplifying the right side
AB = 1105.97652 * .31896 by multiplying both sides by .31896 and clearing fractions
AB = 352.7622, which is 353 rounded to the nearest whole number.
Thus, AB is 353 feet and choice A is the best answer.

Answer:
C
Step-by-step explanation:
Judging by the answers, the lines have slopes of 7/3 and 2/5. (We could verify this by close examination of the graph.) The shading is above (greater than) the line with the smaller slope value (2/5), and below (less than) the line with the steeper slope value (7/3).
That means we're looking for a pair of inequalities with the symbols ...
y ≥ 2/5x ...
y ≤ 7/3x ...
This combination is found in choice C.
