Answer:

D) 300 seconds

Step-by-step explanation:

if the river is traveling 1 m/s and Britney is traveling 2 m/s, then half of her speed would be canceled out, resulting in her only traveling 1 m/s taking her 300 seconds or 5 minutes to complete the trip.

Her speed against current= speed in still water - speed of current
= 2 - 1 =1 meter/seconds
Time taken = distance/ speed
= 300/1
= 300 seconds

Answer:

  • r = √(3V/(πh))
  • r ≈ 1.78 cm

Step-by-step explanation:

Multiply by the inverse of the coefficient of r², then take the square root.

  V=\dfrac{1}{3}\pi r^2h\\\\V=\dfrac{\pi h}{3}r^2\\\\r^2=\dfrac{3V}{\pi h}\\\\\boxed{r=\sqrt{\dfrac{3V}{\pi h}}}

For V=50, h=15, this is ...

  {r=\sqrt{\dfrac{3(50)}{\pi(15)}}=\sqrt{\dfrac{10}{\pi}}\approx\boxed{1.78\quad\text{cm}}

What is the value of. X in this equation<br><br> 1.54x+6.814=8.2
sveticcg [70]

Answer:

x=0.9

Step-by-step explanation:

1. You first have to isolate the x term so you subtract 6.814 from both sides which makes the equation 1.54x=1.386

2. Then, to isolate "x", you divide 1.54 on both sides to get rid of the 1.54 which makes x=.9

A farmer needs 3x2 − 4x + 10 seeds for each of x3 + 5x − 20 fields. What expression would represent the seeds the farmer needs t
Fittoniya [83]

Answer:

Step-by-step explanation:

(3x^2-4x+10)(x^3+5x-20) =3x^5-4x^4+25x^3-80x^2+130x-200

x=1 is not a good value since when you plug it in you get -126 and you can't have a negative number of seeds.
