A hot air balloon went from an elevation of 3,832 feet to an elevation of 3,101 feet in 34 minutes. What was its rate of descent?

Rate of descent in minutes?

Step-by-step explanation:

Step 1. Subtract.  3832 - 3101 = 731

Step 2. Divide.   731 / 34 = 21.5

Step 3. Label.  21.5 Feet

Hope this helps.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
