36 fifth graders are on a team with the same number on students on each team, if there are more then then 1 but less then 20 tea

frosja888 [35]

Depending on the number of teams, the possible numbers of students per team are in the set:

{2, 3, 4, 6, 9, 12, 18}

<h3>How many students can be on each team?</h3>

We know that there are 36 students divided equally into N teams.

Such that the number of teams is larger than 1 and smaller than 20.

Then we could have 2 teams, such that the number of students in each team is given by the quotient between the total number of students and the number of teams.

36/2 = 18

There are 18 students in each team.

Notice that the numbers of teams can only be factors of 36, where:

36 = 6*6 = 2*2*3*3

So the factors are:

2, 3, 2*3, 3*3, etc...

If there are 3 teams we have:

36/3 = 12 students per team.

If there are 6 teams we have:

36/6 = 6 students per team.

if there are 9 teams:

36/9 = 4 students per team.

If there are 12 teams:

36/12 = 3 students per team.

If there are 18 teams:

36/18 = 2 students per team.

These are all the possibilities.

Which function could this graph represent?

puteri [66]

Answer:

y = -2sin(x) + 2

Step-by-step explanation:

The sin(x) function is zero at x=0, so you want a sine function of some sort. The slope of your graph at x=0 is negative so you want a sine function with a negative multiplier. The appropriate choice is the one shown above.

The cos(x) function is 1 at x=0, so any graph involving the cosine will not go through the point (0, 2) the way your graph does.

Help! Please this is hard 8th grade

Nezavi [6.7K]

Combine like terms in Qx + 12 = 13x + P:

x(Q-13) = P-12
P-12
Then x = ----------
Q-13

Note that Q may not = 13. But none of the answer choices present Q = 13.

Let's go thru the answer choices one by one.

P-12
x = ----------
Q-13
-24
Check out A: Q=12 and P= -12: x = -------- = 24 This is OK (ONE sol'n)
-1
-25
Check out B: Q = -13 and P = -13: x = ----------- = 25/26 OK
-26
13-12
Check out C: Q = -13 and P = 13: x = ------------ = -1/26 OK
-13-13

12-12
Check out D: Q = 12 and P = 12: x= ---------- = 0 OK
12-13

It appears that in all four cases, the equation has ONE solution.

What is the measure of an angle if it is 660 less than 6 times its own supplement

otez555 [7]

Answer:

Step-by-step explanation:

Since this angle is unknown, let's just represent it with the variable "x". So the supplement angle of "x" is essentially, the value of the angle that we need to add to "x" to get 180. In other words let's just say that the supplement angle is "y". This means that: $x+y=180$ . If we subtract x from both sides we can represent "y" or the supplement angle as: $(180-x)$ .
