76.3 rounded to the nearest whole number is 76
475,805 rounded to the nearest ten thousand would be 476,000.
Answer:
25.6 units
Step-by-step explanation:
From the figure we can infer that our triangle has vertices A = (-5, 4), B = (1, 4), and C = (3, -4).
First thing we are doing is find the lengths of AB, BC, and AC using the distance formula:

where
are the coordinates of the first point
are the coordinates of the second point
- For AB:
![d=\sqrt{[1-(-5)]^{2}+(4-4)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%5B1-%28-5%29%5D%5E%7B2%7D%2B%284-4%29%5E2%7D)



- For BC:





- For AC:
![d=\sqrt{[3-(-5)]^{2} +(-4-4)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%5B3-%28-5%29%5D%5E%7B2%7D%20%2B%28-4-4%29%5E%7B2%7D%7D)





Next, now that we have our lengths, we can add them to find the perimeter of our triangle:




We can conclude that the perimeter of the triangle shown in the figure is 25.6 units.
A) For object with mass m1,
F = m1 * 3
m1 = F/3
For object with mass m2,
F = m2 * 1
m2 = F
Ratio of m1/m2
(F/3) / F = 1/3
<u>We are given:</u>Distance covered by the fastest man in 9 seconds = 100m
<u>To Find: </u>The distance covered in 1 min 2 seconds or 62 seconds
<u>Finding the Speed of the man:</u>
We know that:
speed = distance covered / time taken
Speed = 100 / 9 <em>(we are given that he travels 100 m in 9 seconds)</em>
Speed = 11.11 m/s
<u>Distance travelled in 62 seconds:</u>
We know that:
distance covered = speed * time
<em>replacing the value of speed and time</em>
Distance = 11.11 * 62
Distance = 688.82 m
