12 red and 36 blue pens. 12/36 = 3/9 so the ratio is correct, and 12+36 = 48 workers.
I think it's to find the sum of the factors of −40.
Hope this helps !

V = u + at
2.8 = u + a*8.5
2.8 = u + 8.5a
s = ut + 0.5at^2
40 = u*8.5 + 0.5*a*8.5^2
40 = 8.5u + 36.125a
(2.8 = u + 8.5a) * 8.5
23.8 = 8.5u + 72.25a
Subtract those equations
16.2 = - 36.125a
a = 0.448
2.8 = u + (8.5*-0.448)
2.8 = u - 3.8
u = 6.6 m/s
Answer:
The circumference of this circle is
feet.
Step-by-step explanation:
Circumference of a circle = 
Where,
r is the radius of the circle.
Therefore, we can find the circumference of the circle by substituting the values to the equation:



The circumference of this circle is
feet. (Rounded to the nearest tenth)
