Hey how about using a calculator?

1/4 x 125.60 = 157/5 = 31.4

A looooooooong one.

ElectricPavlov is right. It's 42 by a long shot.

can you try to do this??? This is very complicated as you know

Just to  make the problem interesting.....let's assume that they start from opposite sides......If Alex has a 30 ft head-start.........the distance between them  is only [199-30] ft  = 169ft

So........in one minute.......they close this distance by  [ 2 + 1.5] ft =  [3.5] ft

So.......the amout of time it will take them to meet   = D/R  = T = 169/3.5 = about 48 +2/7 minutes = about 48 minutes 17 seconds......so, Alissa  passes Alex  after this............

Alissa will never pass him....if she moves 3ft every 2 minutes.......[assuming the rate is constant]....then she only moves 1.5 ft every minute.......and alex is already traveling faster than that [ 2 ft per minute ]

Never !   Not ONLY did Alex get a head start....he is moving faster @ 2 ft/min and Alissa is only going 1.5 ft/min.

If you mean they start on opposite sides then that is something else....but that is not what is written.  o/w 48.28 minutes

199-(2t+30) = 1.5t

169 = 3.5t    t = 48.28 minutes they will pass each other if going in opposite directions.

V_cone =   pi * r^2 * h / 3         where h is the height and pi* r^2 is the area of the base.....so we have....

345  = [ pi * r^2] * 9   / 3     multiply both sides by 3      

1035  /  [ 9 * pi]   = r^2         take the square root of both sides

√ ( [ 1035] /  [9 * pi]   )  =  r  = about 6.05 units

So....the base area =  pi * (6.05)^2  = about  115  units^2

4 is the awnsr

x=2.247

20% = 20/100 = 1/5

Multiply that by 1/5

1,154,358,778 * (1/5) = 230871755.6

same

I'll bet you meant   sqrt(12345678901234567890)         Use a calculator!

587/60 =   9 hrs   +  .78333333 hrs    

.7833333 hrs  x   60 min/hr  =  47 mins          9 hrs 47 minutes  

  27 tadpoles

___________           X    315 Mosquitoes      =   189   tadpoles

45 Mosquitoes
