AfilCa [17]
The information's given in the question are of vital importance. These information's should be very useful while getting to the desired answer of the given question.Let us now concentrate on the problem that needs to be solved.
The height of the sign that casts a shadow of 4 meters is = 5 meters
Then
The height of the tree that casts a shadow of 30 meters = (5/4) * 30 meters
                                                                                          = 150/4 meters
                                                                                          = 37.5 meters
So the tree casting a shadow of 30 meters is actually 37.5 meters in height. I hope the procedure is simple enough for you to understand.

Lesechka [4]

Answer:

1%

Step-by-step explanation:

24(400) = 9600 = total amt paid

9600 - 8000 = 1600 = amt of interest paid

I = PRT         T = 2 yr

1600 = 8000(2)R

1600 = 16000R

1600/16000 = 1/10 = .01 = 1%

weeeeeb [17]

Answer:

Step-by-step explanation:

There has to be at least two T in each result of the simulation. This means you can also have 3 T's and 4 T's in the result.

These are the results that qualify as having at least two T's.

1. TTTT, 2. TTTT, 3. THTH, 4. HTTT, 5. TTTT, 7. HTHT, 9. THTH

That is 7 out of the 10 results which is 7/10 or 70%
