The height of the top of the mountain is 50.67 feet
<h3>The mirror</h3>Jackson placing the mirror in front of him will result in relations that have equivalent ratios.
<h3>Equivalent ratios</h3>So, the equivalent ratios are represented as:
Where x represents the height of the mountain
Cancel out the common units
Express as fractions
Make x the subject
Multiply
Convert the unit to feet
Hence, the height of the top of the mountain is 50.67 feet

Answer:
We can write proportion as:
Step-by-step explanation:
A cyclist rides at a constant speed, traveling 30 miles in 1.5 hours. Write a proportion that gives the number x of miles the cyclist rides in 4 hours
Proportion:
A proportion is used when two ratios are equal. It can be written as a/b=c/d
In our case we have:
a= 30 miles
b = 1.5 hours
c = x miles
d = 4 hours
We can write proportion as:
Answer:
23.05 x 10.85
Step-by-step explanation:
Area of Rectangular Fence = L * W = 250
L * W = 250
W = ................................... (i)
Perimeter = 2L + 2W
Three sides cost 4 dollars per foot = 4(2L) + 4W
(The two lengths must be constructed with the 4 dollars materials)
Fourth side costs 13 dollars per foot = 13W
Cost = 4(2L) + 4W + 13W
C = 8L + 17W ...................................... (ii)
Substitute (i) into (ii)
C = 8L + 17 ()
C = 8L +
Plotting this equation with L on the x-axis and cost on the y-axis
minimum cost will be when L ≈ 23.05 ft
W = ≈ 10.85 ft
minimum cost = 8(23.05) +
minimum cost = 184.4 + 184.382
minimum cost ≈ 368.78 dollars
