Let us say that,
<span>A = perimeter of football field of the 1st
school</span>
B = perimeter of football field of the 2nd school
C = perimeter of football field of the 3rd school
So that:
A = 320 m
B = 360 m
C = 400 m
So the first thing we have to do to find for the minimum
laps to make is to divide every perimeter by the smallest one, therefore divide
all by 320 m, hence:
A’ = 1
B’ = 1.125
C’ = 1.25
Now multiply everything by a number such that all laps
will be a whole number, in this case multiply everything by 8:
A’ = 8
B’ = 9
C’ = 10
Hence the laps to run are:
<span>8, 9 and 10</span>
Answer:
y = - 4.4
Step-by-step explanation:
Given that t varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 6.6 when x = 9.9 , that is
- 6.6 = 9.9k ( divide both sides by 9.9 )
k =
= - 
y = -
k ← equation of variation
When x = 6.6, then
y = -
× 6.6 = - 2 × 2.2 = - 4.4
Answer:
kinectic + electric = internal
Step-by-step explanation:
Internal energy U of a system or a body with well defined boundaries is the total of the kinetic energy due to the motion of molecules and the potential energy associated with the vibrational motion and electric energy of atoms within molecules. Internal energy also includes the energy in all the chemical bonds.
