Answer:

Step-by-step explanation:

Number of shells she had in the begining = 40

Number of shells collected in the morning and at noon = 6 + 3 = 9

Now the number of shell at the end = 40 + 9 = 49

Icreased shells = 49 - 40 = 90

\text{Percentage increase = $\dfrac{49- 40}{40}*100$}

                                =\dfrac{9}{40}*100\\\\\\= 22.5 \ \%

Prove that if a is a natural number, then there exist two unequal natural numbers k and l for which ak−al is divisible by 10.
EastWind [94]
Assume a is not divisible by 10. (otherwise the problem is trivial). 
<span>Define R(m) to be the remainder of a^m when divided by 10. </span>
<span>R can take on one of 9 possible values, namely, 1,2,...,9. </span>
<span>Now, consider R(1),R(2),......R(10). At least 2 of them must have the sames value (by the Pigeonhole Principle), say R(i) = R(j) ( j>i ) </span>
<span>Then, a^j - a^i is divisible by 10.</span>

Given:B is the midpoint of AC. Complete the statement. If AB = 7,then BC = _____, and AC = ____.
Alex73 [517]

Midpoint

We know AC is a segment and B is its midpoint. This means the length of the segment AB is half the length of the segment AC. This also means the length of the segment BC is half the length of AC, and equal to AB.

This can be visualized as follows:

Since AB=7, then BC = 7 and AC=AB+BC = 14

Answer: BC = 7, and AC=!4
