I think it’s the third or second
Answer:
14,334 actually that might not be the answer im just thinking that because the 4 is in the tenths place and ur rounding that u would make it into a whole number
Answer:
400.5 m
Step-by-step explanation:
To avoid any confusion regarding the width of the track itself affecting the perimeter value, the problem is asking you to find the perimeter of the white inner area only. We know that the straight parts of the track has a total length of 212 m (= 2 x 106 m). If we ignore the straight parts, note that the ends are nothing but two halves of a circle or radius 30m (= 60/2 m) where circumference is
C =2(pi)r = 2(3.14)(30m) = 188.5m
Therefore, the perimeter is
P = 212 + 188.5 = 400.5 m
<em>The </em><em>slope</em><em> of the diagonal line of the </em><em>smaller triangle</em><em> is; 1/2</em>
<em>The </em><em>slope</em><em> of the diagonal line of the largest triangle is; 1/2</em>
<em>Both triangles have the </em><em>same slope</em><em> because the rate of change in y-coordinates to that of x-coordinates is the same.</em>
- We want to find slope of the triangles and in mathematics we will adopt the formula;
m = (y2 - y1)/(x2 - x1)
- This simple means change in y-coordinates divided by change in x-coordinates.
The coordinates of the smaller triangle are;
y2 = 1
y1 = 0
x2 = 2
x1 = 0
Thus, slope; m = (1 - 0)/(2 - 0) = 1/2
- For the largest triangle;
The coordinates of this larger triangle are;
y2 = 3
y1 = 1
x2 = 6
x1 = 2
Thus, slope; m = (3 - 1)/(6 - 2)
m = 2/4 = 1/2

Sol. 1) Prime factors of 12 = 2 x 2 x 3
Prime factors of 15 = 3 x 5
Prime factors of 21 = 3 x 7
So, HCF (Product of all common factors of given three numbers 12, 15 and 21)=3
and LCM of 12, 15 and 21 = Product of common factors with other remaining factors i.e., LCM = 3 x 22 x 5 x 7 = 420
2) Prime factors of 17 = 17 x 1
Prime factors of 23 = 23 x 1
Prime factors of 29 = 29 x 1
So, HCF of 17, 23 and 29 = 1
and their LCM = 17 x 23 x 29 = 11339
3) Prime factors of 8 = 2 x 2 x 2
Prime factors of 9 = 3 x 3
Prime factors of 25 = 5 x 5
So, HCF of 8, 9 and 25 is 1 because their is no common factors in the prime factorization of 8, 9 and 25.
Now LCM of 8,9 and 25 = 8 x 9 x 25=1800
