The airplane is 48 feet long in real dimensions.
To find out how long the airplane actually is, we can use the scale and input our amount of inches that it is measured by.
So, 1 inch equals to 6 feet.
Our model plane is 8 inches.
Now, we plug it in.
8 inches = 6(8)
8 inches = 48 feet
Therefore, the length of the real airplane is 48 feet.
48 feet
If your teacher is asking "which of the following can be used to prove the triangles congruent?" then I agree with your statement that it's "none of the above". We simply don't have enough information to determine if the triangles are congruent or not. If we wanted to use SAS, then we'd have to know if EB = BD was true. If we wanted ASA, then we'd have to know that A = C. If we wanted AAS, then we'd have to know that E = D.
In short, you have the correct answer. Nice work.
<u>Answer:</u>
Piston displacement = 84.8
<u>Step-by-step explanation:</u>
We will find the volume of the cylinder in order to find the piston displacement.
Here, (bore = diameter, so r = diameter/2) (height = stroke)
Volume =
= 21.2 cubic units
Since the engine has 4 cylinders, so we will multiply the piston displacement by 4 to get:
Piston displacement =
= 84.8
