Answer:
57.1428571429 miles per hour <em>Round off the answer to what your teacher asked.</em>
Step-by-step explanation:
Since we want final answer in miles per hour, lets change the 30 mins to 0.5 hours
Phase 1 =25miles per 0.5 hours
Phase 2 = (200miles-25miles) per 3 hours
Speed = distance/time
Average speed = total distance/ time
Total distance is 200miles because both phases say from new york that means it travels 25 miles away from new york then 3 hours later it is 200 miles away from new york
total time =3 hours+0.5 hours = 3.5 hours
Average speed = 200/3.5
Average speed = 57.1428571429 miles per hour

Answer:
x = 16 y = 22.627 (or 16
)
Step-by-step explanation:
cos(45) = 16/y
y = 16/cos(45)
y = 22.627
tan(45) = 16/x
x = 16/tan(45)
x = 16
*this can also be found because we know this is a right triangle with two angles of 45 degrees. This means that both sides will be equal so x will be 16 and the diagonal will be 16 root 2 (22.627)
Answer:
x=5.4
Step-by-step explanation:
-2.3(x - 1.2) = -9.66
Distribute -2.3
-2.3x + 2.76 = -9.66 (2 negatives make positive)
Subtract the constant (2.76)
-2.3x = -12.42
Divide by coefficient on both sides to get:
x=5.4
