Answer:
The rate of plane in still air is 834 km/hr and the rate of wind is 80 km/hr.
Step-by-step explanation:
The airplane travels 6032 km in 8 hours against the wind.
So,  ........ (1) {Where u is the speed of plane in still air and v is the wind speed}
 ........ (1) {Where u is the speed of plane in still air and v is the wind speed}
Again, the airplane travels 7312 km in 8 hours with the wind.
So,  ........ (2)
 ........ (2)
Now, adding equations (1) and (2) we get,
2u = 1668
⇒ u = 834 km per hour.
So, from equation (1), we get  
v = u - 754 = 834 - 754 = 80 km per hour.
Therefore, the rate of the plane in still air is 834 km/hr and the rate of wind is 80 km/hr. (Answer)
 
        
             
        
        
        
Answer:
The angles across from the legs are called base angles
Step-by-step explanation:
we know that
The isosceles triangle is a triangle with two equal angles and two equal sides
The two equal sides are called legs and the third side is called base
The two equal angles are called base angles and the third angle is called vertex angle
 
        
                    
             
        
        
        
Answer: C. 966
Step-by-step explanation: First find the ft. of the entire area, the deck, and pool. Then get the area of the pool 
Entire area: (35+7+7) * (20+7+7)= 1666
Pool: 35*20=700
Then subtract the ft. of the entire area by the pool
1666-700= 966
