Answer:
2. 94.0 km/h
Step-by-step explanation:
since the airplane is moving at angle of 54° from the ground, the horizontal component of the velocity is given by cos component
speed of air plane= 160 km/hr
horizontal component of velocity v= 160 cos 54°
= 94.045 km/hr
Thus the truck must travel at an speed of 94.0 Km/hr hence second option is correct.

Answer:
7.0%
Step-by-step explanation:
Here, we want to get the value of the percentage increase
mathematically, we have the formula for this as follows ;
(new value - old value/old value * 100%
from the question, old value is 8,300 ft and the new value is 8,881 ft
So we have the percentage increase as follows;
(8,881 - 8,300)/8,300 * 100%
= 7.0%
You are going to find the different of the new price from the old price . 175.90-153.77=22.13
then you divide the difference by the new prince 22.13/153.77= 0.1439
you are you to multiple the decimal by 100
Your answer is going to be 14.39
Your estimate can be 14%
76.6% so rounded up would be 77% as an a fraction 46/60
