Answer:
The correct answer is 54 rails.
Step-by-step explanation:
Max builds rail fences. For one style of fence, each section uses 3 vertical fence posts and 6 horizontal rails.
For every style of fence Max uses 3 vertical fence posts and 6 horizontal rails.
For every style of fence Max uses vertical fence posts and horizontal rails in the ratio of 1 : 2.
Max uses 27 posts . Therefore he needs to use 27 × 2 = 54 rails.
Therefore Max needs 54 rails for a fence that has 27 posts.
Answer:
<em>q =</em> 150
Step-by-step explanation:
Supplementary angles are angles that form a straight line and have a sum of 180 degrees, e.g. 120 and 60. If its supplement is thirty, and angle <em>q </em>is five times its supplement, it's 150. We know this is correct because 150 + 30 = 180, which is what we need for a supplementary angle.
