Ruby conducted a survey and found that 5/6 of her classmates have a pet and 2/3 of them are dogs what fraction of her classmates
lina2011 [118]
This is how I would solve it, I would act as if there were 36 people in the class.
36÷6=6×5=30
30÷3=10×2=20
20/36=10/18=5/9
You could also try another number such as 24;
24×(5÷6)=20
20×(2/3)=13.3(3 repeating)
13.333/24=5/9
5/9 people have dogs.
Tell me if this helps.

Which points are on the graph of the equation - 3x + 6y + 5 = -7?
ludmilkaskok [199]

Answer:

C and E

Step-by-step explanation:

To solve this problem, let's plug in each coordinates into the equation.

A:

  • -3(-3) + 6(6) + 5 = -7
  • 9 + 36 + 5 = -7
  • 50 = -7
  • 50 \neq -7
  • A. cannot be the answer, as 50 does not equal -7.

B:

  • -3(-2) + 6(0)+5=-7
  • 6+0+5=-7
  • 11=-7
  • 11\neq -7
  • B. cannot be the answer, as 11 does not equal -7.

C:

  • -3(0) + 6(-2) + 5 = -7
  • 0 - 12 + 5 = -7
  • -12 + 5 = -7
  • -7 = -7
  • C. can be the answer, as -7 does equal -7.

D:

  • -3(6)+6(-3)+5=-7
  • -18-18+5=-7
  • -36+5=-7
  • -31\neq -7
  • D. cannot be the answer, as -31 does not equal -7.

E:

  • -3(8) + 6(2) + 5 = -7
  • -24 + 12 + 5 = -7
  • -12 + 5 = -7
  • -7 = -7
  • E. can be the answer, as -7 does equal -7.

Which measure is equivalent to 25,200 seconds?<br><br> 1 min = 60 s<br><br> 1 h = 60 min
sertanlavr [38]

Solution:

<u>Note that:</u>

  • 1 min = 60 sec
  • 1 h = 60 min.

<em>The given time is in seconds. Convert it into minutes by dividing it by 60.</em>

  • => 25,200 seconds = 25,200 ÷ 60 minutes = 420 minutes

<em>The obtained time is in minutes. Convert it into hours by dividing it by 60.</em>

  • => 420 minutes = 420 ÷ 60 hours = 7 hours

<u>We can conclude that:</u>

  • 25,200 seconds = 420 minutes = 7 hours

Consider he following table. Does the table represent a function? Why or why not?
Damm [24]
This is considered a function because each input has a different output. For example, a certain x value doesnt equal 2 different y values, making this a function. Take this: if there is (2,4) and (3,4), this is a function because although the y values are the same, the x values are different. (2,3) and (2,4) do not convey a function because the x values are the same, but each has a different y value.
hope this helped!!!
