If one foot on the model represents 70 feet on the real object, the scale is 1:70. That scale applies to all dimensions and units. In other words, you can divide any object dimension by 70 to find the corresponding model dimension in the same units.
model tail height = 392 inches / 70 = 5.6 inches
model wing span = 2537 inches / 70 ≈ 36.2 inches
model length = 2785 inches / 70 ≈ 39.8 inches
Answer:
l x - 9 l ≤ 0.3y
Step-by-step explanation:
Let x is the length of the pipe
Let y is the length of the diameter
Given that:
- A pipe is to be cut to a length of 9 accurate, we have : x - 9
- Within three tenths of its diameter : 0.3 y
So we have the inequality that model this situation is:
l x - 9 l ≤ 0.3y
Hope it will find you well.
Step-by-step explanation:
the slope of a line is the ratio y/x.
that means, when going from one point to the other, how many units y changes, when x changes a certain number of units.
the sign indicates the direction of the change (+ for larger and - for smaller).
so, here x changes by 6 units (from -3 to 3), and y changes by -2 units (from 4 to 2).
therefore, the slope is
-2/6 = -1/3
