0.2 is the answer I believe ^^
Answer:
m = 21 inches
The model length is 21 inches
Question;
Use the scale factor 1:12 to find the missing dimension. Great white shark actually lengthy 21ft. Find the model length in inches.
Step-by-step explanation:
Given;
Scale factor = 1:12
Actual length a = 21 ft
Let m represent the model length;
The ratio of model length to actually length is given as;
m/a = 1/12
m = a/12
Substituting a=21 ft;
m = 21/12 ft
Converting to inches;
1 ft = 12 inches
So,
m = 21/12 ft × 12 inches/ft
m = 21 inches
The model length is 21 inches
To find the midpoint of a line use the midpoint formula which is M = (x1+x2/2 , y1 +y2/2) After plugging in the coordinates for your variables you should get (-1+5/2, -1+2/2) This simplifies to (2, 1/2) which is the coordinates for the middle point of the base XY.
X must be 4.
