25. ⅕

24. The fastest the runner ran was Wednesday.

Step-by-step explanation:

12⁄138 = 6⁄69 ≈ 0,0869565217

$\frac{3}{31,5} ≈ 0,0952380952$

___

4⁄37 = 0,108

6⁄72 = 1⁄12 = 0,083 ← smallest quantity, fastest time

4⁄38 = 2⁄19 ≈ 0,1052631578

$\frac{1}{5} = \frac{16}{80}$

Greatest Common Divisor [GCD]: 16

$\frac{2}{5} = \frac{4}{10}$

Greatest Common Divisor [GCD]: 2

$\frac{6}{25} = \frac{48}{200}$

Greatest Common Divisor [GCD]: 8

The value of good wine increases with age. Thus, if you are a wine dealer, you have the problem of deciding whether to sell your

Katyanochek1 [597]

Answer: 64 years

Step-by-step explanation:

Let assume the dealer sold the bottle now for $P, then invested that money at 5% interest. The return would be:

R1 = P(1.05)^t,

This means that after t years, the dealer would have the total amount of:

$P×1.05^t.

If the dealer prefer to wait for t years from now to sell the bottle of wine, then he will get the return of:

R2 = $P(1 + 20).

The value of t which will make both returns equal, will be;

R1 = R2.

P×1.05^t = P(1+20)

P will cancel out

1.05^t = 21

Log both sides

Log1.05^t = Log21

tLog1.05 = Log21

t = Log21/Log1.05

t = 64 years

The best time to sell the wine is therefore 64years from now.

Just think of it as normal subtraction. They both have the same denominators all you need to do is subtract. 11/12-7/12 is 4/12 if you simplify which just means to find the number that both 4 and 12 can go into equally the simplified answer would be 1/3. You just need to divide 4 by both the top and the bottom (numerator and denominator).

Scrat [10]

Answer:

4.5 cm.

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

$\text{Circumference of a circle}=2\pi r$
