lin ran 4 laps around the track in 5 minutes, if lin ran 21 laps, how long does it take her

Answers

Answer 1

Answer:

26 1/4 minutes or 1635 seconds

Step-by-step explanation:

Lin runs 4 laps in 5 minutes. You must turn this into a unit rate. In order to do this, you divide 4 laps by 4 to get 1 lap. To get the equivalent, you also have to divide 5 minutes (300 seconds) by 4. This will get you one lap for every 75 seconds. Because Lin ran 21 laps, see how many times 4 can go into 20 using a remainder if necessary. 4 can go into 21 5 times with a remainder of 1. 4*5=20 5*5=25. Now you add 75 seconds because you have an extra lap.

a line has a slope of -19/8 and passes through the point (0,12). what is its equation in slope intercept form​

Answers

Answer:

y=-19/8x+12

Step-by-step explanation:

Slope intercept form is

y=mx+b

m is slope

b is y-intercept

So we already know what the slope is so we can plug that in

y=-19/8x+b

Now  with the point we can substitute x and y with the point values

[Remember a point is (x,y)]

0 is x

12 is y

12=b

So the slope intercept form of this is

y=-19/8x+12

Two sides of a triangle measure 27 inches and 32 inches. Which could represent the length of the third side?

Answers

Answer:

Step-by-step explanation:

The third side could have dimension x

32 - 27 < x < 32 + 27

         5 < x < 59

There are a few special triangles

Equilateral triangle could have legs

27, 32, 27

or

32, 27, 32

A right triangle could have the third side

√(27² + 32²) = √1753 which is about 41.87

or

√(32² - 27²) = √295 which is about 17.18

Notice all these fit within the original limits specified.

Answer:

The third side is greater than 5 but less than 59.

Step-by-step explanation:

Remember: Given any two sides of a triangle, the length of the third side is greater than the difference but less than the sum of the length of the two given sides.

So 27 and 32       The given two sides

   32 - 27 = 5        Greater than the difference   (greater than 5)

   32 + 27 = 59     Less than the sum   (less than 59)

 

the ratio of collectible pennants kyle owns to pennants that yasmine owns is 3:2 yasmine has 36 pennants . How will the ratio of kyles pennants to yasmines pennants change if they both sell half of their pennants Explain

Answers

Answer:

If they both sell half then Kyle would have 1.5:1 and Yasmine would have 18 pennants.

Step-by-step explanation:

It will change because if they both sell half, they would have to multiply by .05  or divide by 2 because that is half of something.

3/2 or 3*0.5 = 1.5

2/2 or 2*0.5 = 1

36/2 or 36*0.5 = 18

So Kyle would have 1.5:1 pennants left and Yasmine would have 18 pennants left.

solve 2/3 - 6y = - 1 5/6

Answers

Answer:

y = 19/36

Step-by-step explanation:

Assuming that what you want is the value of y, you can pass all the right side stuff to the left, and the y to the right:

2/3 + 15/6 = 6y

Then you can sum the fractions on the left by using the same denominators:

4/6 + 15/6 = 6y       ==>      19/6 = 6 * y

then  you can pass the 6 that is multiplying on the right to the left - now dividing:

y = 19/36

Answer:

  y = 5/12

Step-by-step explanation:

  2/3 - 6y = -1 5/6 . . . . . given

  4 -36y = -11 . . . . . . . . . multiply by 6

  15 = 36y . . . . . . . . . . add 36y+11

  15/36 = y = 5/12 . . . . divide by 36, reduce the fraction

_____

Check

  2/3 -6(5/12) = -1 5/6

  4/6 -15/6 = -11/6 . . . . true

A class of 22 students has taken an exam, and the mean of their scores is 76.5. One student takes the
exam late, and scores 92. After including the new score, what is the mean score for all 23 exams? Round
to the nearest hundredth.

Answers

The mean score for all 23 students is 77.17.

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number.

The first step is to determine the total scores of the 22 students.

Total scores = mean score x number of students

22 x 76.5 = 1683

The second step is to add the score of the student that took the exam late tot he total scores.

New total score = 1683 + 92 = 1775

The third step is to determine the new mean score.

new mean score = new total score / total number of students

1775 / 23 = 77.17

Now we have to,

→ Find the required value of x.

The equation is,

→ -6x - 3 = 27

Then the value of x will be,

→ -6x - 3 = 27

→ -6x = 27 + 3

→ -6x = 30

→ x = 30 ÷ (-6)

→ [ x = -5 ]

Hence, the value of x is -5.
