One

Step-by-step explanation:

5% = .05

20x.05 =

1

:)

5% of 20 = 1

Step-by-step explanation:

Step 1: Our output value is 20.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 20=100%.

Step 4: Similarly, x=5%.

Step 5: This results in a pair of simple equations:

20=100%(1).

x=5%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the right hand side of both equations have the same unit (%); we have

20/x = 100%/5%

Step 7: Again, the reciprocal of both sides gives

x/20 = 5/100 ---> 1

Therefore, 5% of 20 is 1.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
