Answer:
a ration 3:4 can be written as a fraction 3/4 or a percent 75%
Step-by-step explanation:
to go from a fraction to a percent divide the numerator by the denominator and multiply by 100.
3/4 = .75
.75 X 100 = 75%
if something happens 3 out of 4 times (3:4) then it will happen in 75 of 100 instances.
100 x = 75
or using the percentage above (in decimal form)
.75(100) = 75
These are just different methods for representing the same information.
1:4 ration is equal to fraction is equal to 25% (or .25)

Answer:
The distance of base of wire to the base of tower is 13.27 ft
Step-by-step explanation:
Given as :
The measure of wire connected between base ad antenna top = 20 ft
The wire is connected to the antenna on tower at height h = 15 ft above the ground
Let The distance of base of wire to the base of tower = x ft
Let the angle drawn on ground = Ф
Now, According to question
<u>In figure AOB</u>
Sin angle =
i.e SinФ =
Or, SinФ =
Or, SinФ =
Or, SinФ =
or, Ф =
∴ Ф = 48.5°
<u>Now, Again from figure</u>
Tan angle =
i.e TanФ =
Or, Tan 48.5° =
Or, 1.13 =
∴ x =
i.e x = 13.27 feet
So, The distance of base of wire to the base of tower = x = 13.27 ft
Hence, The distance of base of wire to the base of tower is 13.27 ft Answer
