Answer:
A landform is a feature on the Earth's surface that is part of the terrain. Mountains, hills, plateaus, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins. Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills.
 
        
             
        
        
        
Answer:
a) θ =  b) r = 31.27 inch
     b) r = 31.27 inch
Step-by-step explanation:
(a)
area of sector:  * r² * θ
 * r² * θ
384 =  * r² * θ
 * r² * θ
384 =  * (24)² * θ
 * (24)² * θ
θ = 384/288
θ = 
(b)
384 =  * r² *
 * r² * 
r² = 384 * 2 * 
r² = 977.848
r = √977.848
r = 31.27 inch
 
        
             
        
        
        
Answer:
23. 1/5 24.7/10 25. 23/50
 
        
                    
             
        
        
        
0.6.
5/9 = 0.5555555... which rounds to 0.6
 
        
             
        
        
        
5% fail
so 100-5=95% are left
percent means parts out of 100
95% of 100 is 

 times 100=95
95 students are left assuming that the 5% that fail fail within 12 months
