Answer:
16.65 feet
Step-by-step explanation:
Okay, we have three boards that are each 6.85 feet long. If we cut 3.4 feet off one board, that board has:
6.85
−
3.4
=
3.45
feet left
If we cut off 0.5 feet off another board, that board has:
6.85
−
0.5
=
6.35
feet left
So, if we take our three new boards, the total length of plywood left is:
6.85
+
3.45
+
6.35
=
16.65
feet
Hope this helps!
Answer:
No
Explanation:
The distance between the two points on the ground = 43km

First, we calculate the distance between the two points in meters.
• 43km = 43,000 m.
Next, determine the distance it will take using the scale.

The distance between the points using the scale is 1.72m.
Next, we see that the dimensions (1.32 m by 0.85 m) are smaller than the length.
As a final check, calculate the length of the diagonal of the map. The diagonal is usually the longest part.
![\text{Diagonal}=\sqrt[]{1.32^2+0.85^2}=1.57m](https://tex.z-dn.net/?f=%5Ctext%7BDiagonal%7D%3D%5Csqrt%5B%5D%7B1.32%5E2%2B0.85%5E2%7D%3D1.57m)
Since 1.57m is still less than 1.72m, the two points cannot be placed on the map.
