<h3>
Answer: Choice A. 13 & 5/8 inches</h3>
Ideally you should always post the diagram to help us see the entire problem; however, the diagram is not needed in this case because we are told the figure is regular decagon. So there are 10 sides and each side is the same length. If each side is x inches long, then the perimeter is 10x inches.
10x = 136 & 1/4
10x = 136 + 1/4
10x = 136 + 0.25
10x = 136.25
x = 136.25/10
x = 13.625
x = 13 + 0.625
x = 13 + 625/1000
x = 13 + 5/8
x = 13 & 5/8
Answer:
Step-by-step explanation:
Total distance = 3 + 2.5 = 5.5mi/h
Total time = 0.75h + 2hr = 2. 75 hr
Average speed = 5.5 / 2.75 = 2
Answer:
2.4
Step-by-step explanation:
3 / 28 = 0.12
(we do this to see how many miles he ran in a minute)
0.12 x 20 = 2.4
(then we multiply how many miles he can run in 20 minutes)
The x-intercept is when y = 0
y = x - 5 → 0 = x - 5 → x = 5
The y-intercept is when x = 0
y = x - 5 → y = 0 - 5 → y = - 5
Answer: x-intercept is (5, 0), y-intercept is (0, -5)
Answer:
The two graphs are perpendicular
Step-by-step explanation:
The slope of the first one is the reciprocal of the second. Also I graphed it.
