Astudent in wildlife management studied trout habitat in the upper shavers fork watershed in west virginia. the springtime water ph of 29 randomly selected tributary sample sites were found to have the following values:

6.2 6.3 5.0 5.8 4.6 4.7 4.7 5.4 6.2 6.0 5.4 5.9 6.2 6.1 6.0 6.3 6.2 5.8 6.2 6.3 6.3 6.3 6.4 6.5 6.6 6.1 6.3 4.4 6.7

do the data of exercise 17.8 (above) give good reason to think that the springtime water the tributary water basin around the shavers fork watershed is not neutral. (a neutral ph is the ph of pure water, ph 7.)

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
