Answer:
<h2>$2.33</h2>
Step-by-step explanation:
To find the cost of 1 pound of bananas we use ratio and proportion
From the question
3 pounds of bananas costs $7
Then 1 pound will cost
We have the final answer as
<h3>$2.33</h3>
Hope this helps you
S = d/t
st = d
t = d/s
The time going is t1.
The time returning is t2.
The total time is 4 hours, so we have t1 + t2 = 4
The speed of the current is c.
The speed going is 9 + c.
The speed returning is 9 - c.
t1 = 16/(9 + c)
t2 = 16/(9 - c)
t1 + t2 = 16/(9 + c) + 16/(9 - c)
4 = 16/(9 - c) + 16/(9 + c)
1 = 4/(9 - c) + 4/(9 + c)
(9 + c)(9 - c) = 4(9 - c) + 4(9 + c)
81 - c^2 = 36 - 4c + 36 + 4c
81 - c^2 = 72
c^2 = 9
c^2 - 9 = 0
(c + 3)(c - 3) = 0
c + 3 = 0 or c - 3 = 0
c = -3 or c = 3
We discard the negative answer, and we get c = 3.
The speed of the current is 3 mph.
The answer is 2, because 4x+20=x+20 if you solve for x the answer will be 2
If two angles are congruent, then they are at the same degree. For example, if one angle is 20 degrees, and another is 20 degrees, then they are congruent. Hope this helps!
