Answer: 0.82 laps per minute

Step-by-step explanation:

Lin is running 21 laps in 25.6 minutes.

To find out her speed in laps per minute, divide the distance she has ran by the time it took her to run it.

= Distance / time

= 21 / 25.6

= 0.82 laps per minute

Phantasy [73]

Answer:

14 units

Step-by-step explanation:

Solution:-

A(5,1)B(7,1)

\sqrt{(x_{1}-x_{2} ) ^{2}(y_{2} -y_{1}x^{2}    }

AB=\sqrt{(7-5)^{2} +(1-1)^{2} }

= \sqrt{2^{2} } =2

BC=\sqrt{7-7^{2}+(6-1)^{2}  }

=\sqrt{5^{2} } =5

perimeter=2(AB)+2(BC)

= 2(2)+2(5)\\

= 4+10= 14

-----------

hope it helps...

NemiM [27]
<h3>Answer:</h3>

Rise: -4

Run: 3

<h3>Solution:</h3>
  • The rise is how many units we move up or down.
  • The run is how many units we move left or right.
  • We move down 4 units, so the rise is -4.
  • Then, we "run" 3 units, so the run is 3.

Hope it helps.

a jar contains half dollars and quarters. there are 30 coins in all in the jar. the total value of the coins is $8.75. how many
OLEGan [10]
25 quarters because if you set up a system of equations you get x+y=30 since there are x number of half dollars and y number of quarters plus each other is 30. Next equation is .5x+.25y=8.75 half dollar is 50cents while a quarter equals 25 cents and together they have to equal 8.75. Now you eliminate one variable then you add the remaining variable and the amounts together then you divide if you eliminated the x variable your answer is the one you get after you divide. If you eliminate the y variable then you have to plug it then you get your answer. hope this helped
