The actual wingspan of fly is 5.5cm
Step-by-step explanation:
Given,
Scale of drawing;
4mm = 1cm
Ratio of mm to cm = 4:1
Wingspan of fly in drawing = 22mm
Let,
x be the actual wingspan.
Ratio of mm to cm = 22:x
Using proportion;
Ratio of mm to cm :: Ratio of mm to cm
Product of extreme = Product of mean
Dividing both sides by 4
The actual wingspan of fly is 5.5cm

Answer:
The equation of line is y = 4x + c
Step-by-step explanation:
Given the following data;
Slope, m = 1/2
Points = (-6, 12)
To find the equation of line;
Equation of straight line is y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Substituting the values in order to find the intercept, we have;
12 = ½(-6) + c
12 = -3 + c
c = 12 + 3
c = 15
Therefore, the equation of line is y = 4x + c
