Answer:

60%

Step-by-step explanation:

Since theres 80 people and 32 do recieve the free dessert... 80-32=48 which is the amount of people that dont get free dessert. 48/80 to a decimal is 0.6 and 0.6 to a percentage is 60%

hope I helped :)

A hiker walks at a speed of 3 2 5 kilometers per hour. How many kilometers will the hiker walk in
Vika [28.1K]

Answer:

  = 2  4/15 km

Step-by-step explanation:

Speed = 3 2/5 km/hour

The units are not the same.  The speeds is in hours and the time is in minutes

Lets convert minutes to hours.  60 minutes = 1 hour

40 minutes * 1 hour/ 60 minutes = 40/60 hours = 2/3 hour

Distance = speed * time

                  = 3 2/5 * 2/3

Change the mixed number to an improper fraction

  3 2/5 = (5*3+2)/5 = 17/5

                   = 17/5 * 2/3

                  = 34/ 15  km

Change this back to a mixed number

 15 goes into 34 2 times  (15*2 = 30)  with 4 left over

                  = 2  4/15 km

  • Distance Formula: \displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-6, -5)

Point (2, 0)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

  1. Substitute [DF]:                    \displaystyle d = \sqrt{(2+6)^2+(0+5)^2}
  2. Add:                                      \displaystyle d = \sqrt{(8)^2+(5)^2}
  3. Exponents:                           \displaystyle d = \sqrt{64+25}
  4. Add:                                      \displaystyle d = \sqrt{89}

Solve.. -x/6&gt;3<br><br> A)x&lt; -18<br><br> B)x&lt;18<br><br> C)x&gt;18<br><br> D)x&gt; -18
ehidna [41]

Answer:

x < -1/2

Step-by-step explanation:

Starting with -x/6>3, multiply both sides by -1/6, to remove fractions.  Remember to reverse the direction of the inequality sign, which is required because we're multiplying -x/6>3 by a negative number.

x < 3(-1/6), or x < -1/2
