AnswerAnd Step-by-step explanation:
7-5x2+3
x= times or multiplied
First, 10 goes into 47, 4 times.
4 is your whole number.
10 x 4 = 40
47 - 40 = 7
then put 7/10
Put them together and your answer will be (4 7/10)
The median would be 13.5 because that's the middle of all the numbers lined up from smallest to largest and the mean would be 12.7 because that's all the numbers added up divided by how many numbers there are
Suppose the length of the card board was x cm by x cm
After squares of 4cm was cut from the corner, the dimension for the box will be:
length=(x-8) cm
width=(x-8) cm
height=4 cm
thus the volume will be:
V=length*width*height
V=4×(x-8)×(x-8)=144
x²-16x+64=36
this can be simplified to form a quadratic equation given by:
x²-16x+28=0
solving the quadratic equation we get:
x=2 or x=14
Thus we conclude that the original dimensions was:
length=14 cm ; width=14 cm
For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:
Where "r" represents the radius of the circle, in this case 
Substituting in the perimeter equation we have:
Rationalizing we have:
Taking out common factor
