The minute hand of a clock is 8 inches long. To the nearest tenth of an inch, how far does the tip of the minute hand travel as
lesya692 [45]

Answer:

The tip of the minute hand travels 20.9 inches.

Step-by-step explanation:

We are given that the minute hand of a clock is 8 inches long. And we have to find that how far does the tip of the minute hand travel as the time progresses from 12:00 to 12:25.

<u>So, firstly we will find the circumference of circle;</u>

       Circumference of circle (C)  =  2\pi r   {where r is radius of circle}

                                                      =  2 \times \pi \times 8   {given r = 8 inches long}

                                                      =  16 \pi

Now, as we know that the minute hands completes the full circle in 60 minutes, therefore, the length of the arc between time 12:00 to 12:25 represents  \frac{25}{60}  which is  \frac{5 }{12}  of the circumference, that means;

The length of arc from time 12:00 to 12:25  =  \frac{5}{12}\times \text {Circumference of circle}

                                                                       =  \frac{5}{12} \times 16 \pi

                                                                       =  \frac{20}{3} \pi = 6.67\pi

Now, assuming value of \pi = 3.14; so 6.67\pi =  6.67 \times 3.14 = 20.9 inches (in nearest tenth)

Hence, the tip of the minute hand travels 20.9 inches.

Let Jenny = J

Let Mica = M

J = M + 4

Now you have to represent 5 years ago

J - 5 = 2*(M - 5)

J - 5 = 2M - 10                Substitute J = M + 4 Into this equation

M + 4 - 5 = 2M - 10        Combine terms on the left

M - 1 = 2M - 10               Add 10 to both sides    

M - 1 + 10 = 2M              Combine one the left

M + 9 = 2M                    Subtract M from both sides

9 = 2M - M              

9 = M                             Answer Miki

J = M + 4                       Substitute Miki's age for M

J = 9 + 4                         Answer Jenny

J = 13

Answer:

Jenny = 13

Mika = 9

What is the answer (x+5/2)^2= (-5/2)
sashaice [31]

(x + 5/2 * 2/5)^2 = -5/2

(x)^2 sqrt 2 = -5/2 sqrt 2

(x) = i sqrt10/2 - 5/2, i sqrt10/2 - 5/2
