If you take the total height and divide it by the number of cases it, it will then give you the heigh of just one case.
90 divided by 6=15
It’s 15 millimeters per DVD case. Then you take 15 and multiply it by 13 to get the total height of the stack of 13 cases.
Hope this helps!

A circle circumference is 600 M. what is the good approximation of the circle area

wlad13 [49]

Answer:

The area of the circle is 28662 M².

Step-by-step explanation:

Given:

Circumference of circle = 600 M.

Now, to find the area of the circle.

So, to get the area we need to find the radius.

By putting the formula of circumference we get the radius:

Let the radius be r.

Circumference = 2πr

$600 = 2\times 3.14\times r$ (taking the value of π = 3.14.)

$600=6.28r$

Dividing both sides by 6.28 we get:

$95.54=r$

Now, for getting the area we put the formula:

Area = πr²

$Area = 3.14\times 95.54^{2}$

$Area = 3.14\times 9127.89$

$Area = 28661.57$

So, approximately the area of the circle = 28662 M².

Therefore, the area of the circle is 28662 M².

The standard form of the equation of a parabola is y= x2 - 8x + 29.

fomenos

Answer:

Step-by-step explanation:

Put brackets around the first two tems.

y = (x^2 - 8x) + 29

Take 1/2 coefficient of the linear term -8. Square that result. Add it inside the brackets.

1/2 (- 8) = - 4

(- 4)^2 = 16

y = (x^2 - 8x + 16) + 29

Subtract 16 outside the brackets.

y = (x^2 - 8x + 16) + 29 - 16

Do the subtraction

y = (x^2 - 8x + 16) + 13

Represent what is inside the brackets as a square.

y = ( x - 4)^2 + 13

The answer is A
