If there are n different things in a circular arrangement, the number of ways of arranging them is (n - 1)!
The number of ways the desserts can be arranged on the circular tray is:
(7 - 1)! = 6 * 5 * 4 * 3 * 2 * 1 = 720 ways

An apartment lease states that the rent will go up $60 each year. The rent in the 6th year is $1250. Identify the slope and poin
oksano4ka [1.4K]

Answer:

The slope of the linear equation will be 60 and the point on the line will be (6,1250).

R - 1250 = 60(y - 6)

Step-by-step explanation:

An apartment lease states that the rent will go up by $60 each year. The rent in the 6th year is $1250.

Therefore, the slope of the linear equation will be 60 and the point on the line will be (6,1250).

Now, the point-slope form of the linear equation which models the rent (R(y)) in terms of how many years (y) the tenants have lived there will be

R - 1250 = 60(y - 6) (Answer)

Find the distance between the points (0,-8) and (3,2). Round your answer to the nearest hundredth.
Reil [10]

Answer:

10.44

Step-by-step explanation:

First plot each of the points on to a graph at their respective positions.

Following that create a 90° triangle out of the points. This will create a 3 by 10 triangle. (3 to 0 is 3) (-8 to 2 is a difference of 10)

You can then use the pythagorean theorem a^{2} +b^{2} = c^{2}.

Insert the lengths of each of the sides that we got earlier which would be 3 and 10 into the equation. 3^{2} + 10^{2} = c^{2}

Since we want to find the hypotenuse which is equal to c we work the equation to 9+100 = c^{2} which in turn is 109 = c^{2}

Then take the square root of 109 to remove the square from the c to get c = 10.44

Can someone explain to me in words how to do this problem 3x+122=22x-11
inn [45]

When you have this type of problem, you need to combine the like-terms and isolate the variable.

3x + 122 = 22x - 11

Add 11 to both sides to get rid of it

3x + 122 + 11 = 22x - 11 + 11     (-11 + 11=0)

3x + 133 = 22x

Then you would bring the 3x to the other side, so subtract 3x from both sides

3x + 133 = 22x

-3x             -3x

133 = 22x - 3x

133 = 19x

Then divide both sides by 19 to isolate x

133/19 = 19x/19

133/19 = 7, so x = 7

Hope this helps!!
