Answer:
1 mi/hr
Step-by-step explanation:
Given that:
Speed in still water, s = 5 mi/hr
Let speed of current = x
Time = distance /speed
Upstream (subtract speed of current) = 5 - x
Upstream time = 8 / 5 - x - - - (1)
Downstream (add speed of current) = 5 + x
Downstream time = 12 / 5 + x - - - (2)
Equate (1) and (2)
8 / (5 - x) = 12/ (5 + x)
8(5 + x) = 12(5-x)
40 + 8x = 60 - 12x
40 - 60 = - 12x - 8x
-20 = - 20x
x = 1
Spwed of current = 1 mi/hr
Answer:
<h2><em><u>448</u></em><em><u> </u></em><em><u>sq.ft</u></em></h2>
Step-by-step explanation:
The following figure is a <em><u>trapezium</u></em><em><u>, </u></em>
<em><u>So</u></em><em><u> </u></em><em><u>Given</u></em><em><u>,</u></em>
Parallel sides of the trapezium = 17ft and 39ft
Height of the trapezium = 16ft
<em><u>Therefore</u></em><em><u>, </u></em>
Area of the trapezium





<em><u>Hence</u></em><em><u>,</u></em>
<em><u>448</u></em><em><u> </u></em><em><u>sq.ft</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>area</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>trapezium</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Answer:
Mean, range, mode, median
Answer:

Step-by-step explanation:
From the question we are told that:
Angle of F 
Length of 
Length of 
Generally the equation for Angle D
is mathematically given by
Since
.The triangle is a right angle Triangle
Therefore




Answer:
Solving for the value of x in the inequality will give us an answer of x > 7. Thus, the side of the congruent side of the triangle should be greater than 7 feet.
