Answer:
t = 0.7
Step-by-step explanation:
s = k/t  where 'k' is the constant of variation
given:  0.5 = k/7 so k = 3.5
5 = 3.5/t
5t = 3.5
t = 0.7

Answer:
It is a fraction that represents one integer (1) being divided by a second integer (11). The fraction 1/11 is a rational number. It is a fraction that represents one integer (1) being divided by a second integer (11).
 
        
                    
             
        
        
        
Answer:
x = 20°
y = 30
Step-by-step explanation:
The triangle given on close inspection, it is an equilateral triangle. 
Each angle in an equilateral triangle is equal. Likewise, each side is equal. 
Thus;
16 + y = 46
y = 46 - 16
y = 30
The triangle that has angle 80°, the other complete angle is 60° because it's an angle of an equilateral triangle. 
Thus, the smaller angle there is;
180 - (80 + 60) = 40°
Because sum of angles in a triangle is 180°
Now, x + 40 = 60°
Since that's also an angle of an equilateral triangle. 
x = 60 - 40
x = 20°
 
        
             
        
        
        
Answer:
a = 1.8 cm 
Step-by-step explanation:
Here. we want to find the value of a 
To do this, we are going to use the sine rule 
it states that the ratio of a side and the sine of the angle that faces the side is a constant for all the sides of a triangle 
From the diagram, we have that;
The angle facing a is;
180-15-105 = 60
So, we have that 
a/sin 60 = 2/sin 105 
a = 2sin 60/sin 105
a = 1.794 cm
