Sin. Cos. Tan.
1) we have a opposite and adjacent so we're going to use tan.
48÷Tan(73)=14.6750
2) we have the hypotenuse and the adjacent so we use cos.
40×cos(70)=13.6808
WE know that (distance) = Speed * time
and Speed = distance/time & time = distance/speed
Let AB = 60 mi. & the speed is 55 mi/h , then the spent to reach the rink is
t= 60/55 = 1.09 h
Since the total time is 2.75 h & he spent 1.09h to go to the rink, so the time spent on his way back is 2.75-1.09 = 1.659 h
So his speed on his way back is 60/1.659 =36.16 mi/h
Answer:
B. 1/392 cubic yard
Step-by-step explanation:
The volume is the product of base area and height:
V = Bh = (1/28 yd²)·(1/14 yd) = 1/(28·14) yd³ = 1/392 yd³
