Find the arc length for arcs of circles as follows:
Sauron [17]

Answer:

≈ 11.78 in

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{\frac{\pi }{4} }{2\pi } ( cancel 2π on numerator/ denominator )

     = 15 × \frac{\pi }{4}

     = \frac{15\pi }{4}

     ≈ 11.78 in ( to 2 dec. places )

Lin took 75 boxes of carrots and 80 boxes of potatoes to the market. She sold 68 boxes of carrots and 71 boxes of potatoes. How
enot [183]

For this case we have:

x: Represents the number of carrot boxes

y: Represents the number of boxes of potatoes

Initially we have:

x = 75\\y = 80

If you sold 68 boxes of carrot we have:

x = 75-68 = 7

If you sold 71 boxes of potatoes, we have:

y = 80-71 = 9

The number of boxes I take home is given by:x + y = 7 + 9 = 16

ANswer:

7 boxes of carrots left

There are 9 boxes of potatoes left

A total of 16 boxes remain

What is -(5x+6)-x=-6-6x
Veronika [31]

Answer: All real numbers are solutions.

Step-by-step explanation:

<u>Let's solve your equation step-by-step.</u>

−(5x+6)−x=−6−6x

<u>Step 1: Simplify both sides of the equation.</u>

−(5x+6)−x=−6−6x

−5x+−6+−x=−6+−6x(Distribute)

(−5x+−x)+(−6)=−6x−6(Combine Like Terms)

−6x+−6=−6x−6

−6x−6=−6x−6

<u>Step 2: Add 6x to both sides.</u>

−6x−6+6x=−6x−6+6x

−6=−6

<u>Step 3: Add 6 to both sides.</u>

−6+6=−6+6

0=0
