6 foot makes 4.5 foot shadow
1 foot makes=4.5/6
so 50 foot =4.5/6*50 = tree makes 37.5 foot shadow
Answer:The answer is C
Step-by-step explanation:
A. Meters
B. Seconds squared
C. Seconds
D. Seconds per meter
Answer:
D
Step-by-step explanation:
Terms are separated by addition and subtraction symbols.
Polynomials consist of terms that are constant and/or variable. The variable terms must have 0 or positive exponents. Polynomials will not consist of division of variable expressions.
Examples of polynomials:




Examples of non-polynomials:


In general a polynomial when written in standard form should be comparable to:

where the
's could be zero and all the exponents,n, are positive or 0.
D is comparable since all of these are 0 except
which is 1 and
which is -2.
Also the other choices have either division by variable expressions and/or negative exponents on variables.
This is how you would arrive to the answer 37
The time taken for radio signal to the earth's surface we shall proceed as follows;
time=(distance)/(speed)
Distance=7.5×10^6 meters
speed=3×10^8 meters/second
therefore:
Time=(7.5×10^6)/(3×10^8)=0.025 seconds
We conclude that it will take the signal 0.025 seconds to reach the surface of the earth.
