Answer:
48
Step-by-step explanation:
If we know that the max possible score is 100%, and she got 80% for getting 60 marks, we can set it up as a porportion. 
60 * 80 = 4800
4800/100 = 48

Answer:
a. m<B = 100°
b. m<L = 55°
c. Scale factor = 9/11
Step-by-step explanation:
a) Similar triangles have their three corresponding angles congruent to each other, while the ratio of their corresponding sides are proportional to each other.
Since ∆ABC ~ ∆GLJ, therefore,
<A = <G,
<B = <J
<C = <L
m<J = 100° (given)
Therefore,
m<B = m<J = 100°
m<B = 100°
b) m<A = m<G
m<A = 25° (given)
Therefore,
m<A = m<G = 25°
m<G = 25°
m<L = 180° - (m<J + m<G)
Substitute
m<L = 180° - (100° + 25°)
m<L = 55°
c) scale factor of smaller triangle to the larger = side length of smaller triangle / corresponding side length of bigger triangle 
Scale factor = AB/GJ
Substitute
Scale factor = 18/22
Simplify 
Scale factor = 9/11
 
        
             
        
        
        
Answer:
-1.9f-20
Step-by-step explanation:
-2.7f+0.8f-16-4
<em>Collect similar items</em>
-2.7f+0.8f=-1.9f
=-1.9f-16-4
<em>Subtract the numbers</em>
-16-4=-20
=-1.9f-20
