Karo-lina-s [1.5K]

Answer:

d_2=-8.32ft

Step-by-step explanation:

From the question we are told that:

Height of first draw down h=30

Pump Discharge Q=250gallons/day

Well 1 depth d_1=10ft

Transmissivity\=T 10.0 ft2/day

Radiusr=0.5

Well 2 depth d_2=50ft

Generally the Thiem's equation for Discharge is mathematically given by

 Q=\frac{2\piT(h_2-h_1)}{ln(\frac{r_2}{r_1})}

 250=\frac{2*\pi 10 (10-d_2)}{ln(\frac{50}{0.5})}

 1151.293=2*\pi 10 (10-d_2)

 d_2=-8.32ft

1. Ashley and Emma are reading the same article. Ashley is on page 1 of
konstantin123 [22]

Answer:

It will take 6 minutes by Ashley and Emma to read the same amount of pages.

Step-by-step explanation:

Let in 't' minutes Ashley and Emma will read the same amount of pages.

If  Ashley can read one page in a minute then she can read the number of pages in t minutes = 1×t =t

If she starts from page 1 then after time 't' she will be at the page = (t + 1)

Similarly, if Emma takes 3 minutes to read the amount of pages = 1

Then she can read amount of pages in t minutes = \frac{t}{3}

If Emma starts from page 5 then after t minutes she will be at the page = (\frac{t}{3}+5)

If both have read the same amount of pages then,

(t+1)=\frac{t}{3}+5

t-\frac{t}{3}=5-1

\frac{2t}{3}=4

t = 6 minutes

Therefore, it will take 6 minutes by Ashley and Emma to read the same amount of pages.

Answer:

  11/6

Step-by-step explanation:

  \dfrac{6}{3}+\left(-\dfrac{1}{6}\right)=\dfrac{12}{6}-\dfrac{1}{6}=\dfrac{12-1}{6}\\\\=\boxed{\dfrac{11}{6}}

As a mixed number, this is 1 5/6.
