The number of children is 4 and the number of notebooks is 60.

<u><em>Explanation</em></u>

Lets assume, Mama has x number of children and y number of notebooks.

If she give 13 notebooks to each of her children, then 8 books are left. So,

y=13x+8 ...............................(1)

And If she give 15 notebooks to each of her children, she will have nothing left. That means y= 15x ..............................(2)

Now solving the system of equations, we will get ....

13x+8=15x\\ \\ 13x-15x= -8\\ \\ -2x= -8\\ \\ x=\frac{-8}{-2}=4

Now, y=15x=15(4)=60

So, the number of children is 4 and the number of notebooks is 60.

A rectangle is 6 inches longer than it is wide. The perimeter of the rectangle is 44 inches.Write and solve an equation for the
Nataly_w [17]

Answer:

Length is 14 in

Width is 8 in

Step-by-step explanation:

<u>Given:</u>

  • Length = l
  • Width = w
  • Perimeter = P = 44 in
<h3>Solution</h3>

<u>Equations as per given:</u>

  • l - w = 6
  • P= 2(l+w) = 44 ⇒ l +w = 22

<u>Adding up the two equations:</u>

  • l - w  + l +w = 6 + 22
  • 2l = 28
  • l = 28/2
  • l = 14 in

<u>Then finding the value of w:</u>

  • w = l -6
  • w = 14 - 6
  • w = 8 in

<u>Answer:</u> The length of the rectangle is 14 inches and width is 8 inches

Three of the four vertices of a rectangle are located at (4, 2), (7, 2) and (4, 8). a. What are the coordinates of the missing v
34kurt

Answer:

a) The coordinates of the missing vertex = (7, 8)

b) Area = 18 square units

   Perimeter = 18 units

Step-by-step explanation:

a) We know three of the four vertices:

A: (4, 2)           C ______ D(?)

B: (7, 2)               |             |

C: (4, 8)           A |______| B  

To find the coordinates of the missing vertex we need to calculate the distance in the x-direction from point A to point B:

B_{x} - A_{x} = 7 - 4 = 3                    

Hence, the distance of point D from point C in the x-direction is:

D_{x} = C_{x} + 3 = 4 + 3 = 7

Now, to find the coordinate in "y" we need to calculate the distance in the y-direction between point C and point A:

C_{y} - A_{y} = 8 - 2 = 6  

Then, the distance of point D from point B in the y-direction is:

D_{y} = B_{y} + 6 = 2 + 6 = 8

Therefore, the coordinates of the missing vertex (point D) are:

D = (D_{x}, D_{y}) = (7, 8)    

b) The area of the rectangle is:

a = (B_{x} - A_{x})*(C_{y} - A_{y}) = 3*6 = 18 units^{2}

The perimeter is given by:

p = 2*(3 + 6) = 18 units

I hope it helps you!

In the diagram below, ΔABC is inscribed in circle P. The distances from the center of circle P to each side of the triangle are
4vir4ik [10]
Supposing the sides with 6 and 8 is a right angle, you can create a new line from C and P, and find the length using the equation of a²+b²=c² or 6²+8²=c², with c equaling the radius of the circle.

After finding c, you will have to find the length from C to the midpoint of AC, using the same equation a²+b²=c². If both the lengths of C to the midpoint of AC, and A to the midpoint of AC are equal, you can do b+b to find the length of AC.

Using the same approach, you can find AB. Hope this makes sense, if not, I can clarify more.
