Answer:
she cut 6 inches of tape 
Step-by-step explanation:
you can start by multiplying 3/8 and 6/1 which gives you 6
 
        
                    
             
        
        
        
The anser is C for reasons of science ;)
        
             
        
        
        
Total ratio = 4+7 = 11
33/11 = 3
4x3 = 12
7x3 = 21
so the two groups are 12:21
which is also = 4:7
        
             
        
        
        
Answer:
This is trigonomentry
Use SOHCAHTOA
where :
s is sin
c is cos
t is tan
o is opposite (side)
h is hypotenuse (opposite of 90 degree angle)
and a is adjacent (side)
Sin = o/h
cos = a/h
tan = o/a
in this case we are looking for side BC which is the hypotenuse(h)
and we have the side adjacent(a) to angle 71
since we have a and h determine what to use SIN, COS, OR TAN?
we should use Cos
they‘ve given the angle so we should do this...
Cos71 =  
 
Cos71 = 
now apply algebra...
6.3/cos71= BC
BC= 19.3507869666
BC = 19.4   (3SF)
