Length of circular track is:
L = 2*r*pi
He run 3/4 of it so length is:
L' = 3*2/4*r*pi = 3/2*r*pi
To calculate speed of his movement we use formula:
v = s/t where s = L' and t = 1 minute 45 seconds = 105 seconds
v = L'/t = 3*r*pi/2*105
v = r* pi/70
If we take that r = 1
answer
Answer:
90
Step-by-step explanation:
it is 90 because in the first slot there can be any 10 numbers and in the second slot the set can contain any of the remaining 9 numbers and then we can multiply these two numbers together to find the total amount of sets.
hope this helps :)
The answer is 2x-10.
(x-5)2
=(x+-5)(2)
=(x)(2)+(-5)(2)
=2x-10
Answer:
<h2>V=1/3 pie r^2h (Formula)</h2><h2>12×22/7=1/3×22/7×3^2×h</h2><h2>Eliminate 22/7</h2><h2>12=(9×h)/3</h2><h2>Make "h" the subject of the equation </h2><h2>h=36/9</h2><h2>h=4m</h2>
The greatest common factor of 6 and 24 is 6.
Divide the numerator and denominator by 6.
6/24 = (6/6) / (24/6) = 1/4
