Answer:
2 hours.
Step-by-step explanation:
Money earned for 14 hours of life-guarding = 14*18 = $252. If he worked another 5 hours to make the maximum of 19 he would earn 252 + 5*9
= $297 but he wants to work a minimum of hours for a minimum of 270.
Thus we have the inequality:
252 + 9x ≤ 270
9x ≤ 18
x ≤ 2.
So the number of hours he must do clearing tables = 2.
ANSWER
x=35°
EXPLANATION
The sine and cosine ratio are complementary trigonometric ratios.
This means that:
sin(A)°=cos(90-A)°
The given equation is:
sin(55)°=cos(x).
This implies that,
x=90-55
x=35°
The answer is choice “Yes”
Answer:
15.) BAD = 10. (Since AC is 8 and CD is 2 you'll add em together to form a right angle, and BAD is a right angle so therefore they are the same.)
16.) AB = 2. (CD is 2 so therefore AB is 2, Again same size...)
17.) BD = 8. (Same size as AC...)
