Speed = distance / time
Speed = ?
Distance = 350km
Time = 5 hours
350km / 5hours = 70
He averages 70km/h
Answer:
-3=b
Step-by-step explanation:
since its a -4 u seperate it from the vari by dividing 12 by the -4 ( since -4b inplies multiplcation. u always do inverse operation.)
Answer:
? = 500
Step-by-step explanation:
-589 + 90 = -499
-499 + (-1) = -500
-500 + ? = 0
? = 500
i hope this helps! have a wonderful rest of ur day :)
and if its not too much to ask could you mark me as brainliest, im trying to rank up this month and i only need 2 more, if not thats ok! ty and tell me if theres anythign else you need help with!!

Answer: 24pi feet</h3>
Work Shown:
The area is 144pi square feet. So A = 144pi is plugged into the formula below to isolate r
A = pi*r^2
144pi = pi*r^2
144 = r^2 .... divide both sides by pi, the pi terms cancel
r^2 = 144
r = sqrt(144) ... take the square root of both sides
r = 12
This is plugged into the circumference of a circle formula
C = 2*pi*r
C = 2*pi*12
C = 2*12*pi
C = 24pi
This is approximately equal to 75.36 when you use the approximation pi = 3.14
