The figure below shows the ideal pattern of movement of a herd of cattle, with the arrows showing the movement of the handler as

he moves the herd. The arc the handler makes from the starting point to the return point should be a quarter of a circle.. . . . Based on this theory, what distance will the handler move from the starting point to the return point if he creates an arc of a circle of radius 85 feet?. Answer. 21.25. 66.73 feet. 88.97 feet. 133.45 feet.

<span>The arc length in degrees (same as central angle that cuts it off) is to 360 (degrees in a circle) AS the arc length in linear measure is to the circumference of the circle (2 pi r).
90/360 = AL/[2 pi (85)] where AL is the arc length in linear measure.
 1/4 = AL/[170 pi]
4 AL = 170 pi
 AL = 42.5 pi
 AL = 133.45 feet (approx)

I hope your satisfied with my answer in feel free to ask for more

Answer:

Each hat is $5

Each mask is $3

Step-by-step explanation:

Hat= x dollars

Mask= y dollars

Now,

3 hats and 4 mask sold = $27

We can write

3x + 4y = 27

Adding the second equation (-1 times 1st equation) gives us;

3x + 6y = 33

-1* (3x + 4y = 27)

3x + 6y = 33

-3x -4y = 27

2y = 6

y = 6/2

***y = 3***

Now we replace y= 3 into 1st equation and solve for x:

3x + 4y = 27

3x + 4(3) = 27

3x + 12 = 27

3x + 15

x = 15/3

***x= 5***

Each hat costs $5

Each mask costs $3

The expressions 100×10 and the more complicated

(100 - 4a)(10 + a)

are calculating annual (expected) revenue.  In 100×10 the 100 is the number of decks and the 10 is the price per deck.  In (100 - 4a)(10 + a) the 100-4a is the number of decks and the 10+a is the price per deck.  So a must be the amount the price increases.

Answer: amount of price increase, last choice
