Answer:

108 centimeters

Step-by-step explanation:

Given that :

Scale model used for the Eiffel Tower :

2 centimeter represents 6 meters;

This means 2 centimeters on the model represents 6 meters of the Eiffel Tower.

To obtain the height of the model in centimeter :

Let the height of the model = h

h of model = actual height of tower

Actual Height of tower = 324 meters

Using cross multiplication :

2 = 6

h = 324

6 * h = 324 * 2

6h = 648

h = 648 / 6

h = 108

Hence, height of the model = 108 centimeters

Find the mean of the set of data: 10, 12, 29, 2, 19, 42, 23, 23
Softa [21]
To find mean, 
first add all the numbers together:
10 + 12 + 29 + 2 + 19 + 42 + 23 + 23 = 160

Then divide the total by the <em>amount </em>of numbers there are:

In this case, there are 8 numbers.

160/8 = 20 

20 is your mean for this set of data

hope this helps

What is the determinant of the matrix [598−2]
mihalych1998 [28]

Answer:

  -82

Step-by-step explanation:

Maybe you want the determinant of ...

  \left[\begin{array}{cc}5&9\\8&-2\end{array}\right]

The determinant of a 2×2 matrix is the difference of the products of elements on the down diagonal and the up diagonal:

  D = (5)(-2) -(8)(9) = -10 -72 = -82

The determinant of this matrix is -82.

How do you find the radius of a right cylinder with having the height and surface area?
RoseWind [281]
So we know that surface area is top circle +bottom circle+ (circumfurence times height so) 2(π(radius)^2)+(height(2π(r))) so fill in the blanks
it's kind of hard to see but πr means pi times radius (r)
2πr^2+((4.2)(2)(π)(r))=628.3
factor out the 2 so  the equation would mean
2((πr^2)+(4.2πr))=628.3
divide both sides by 2
πr^2+4.2πr=314.15
what's interesting is that the first few digits of pi are 3.1415 so we aproximate pi as 3.14 and divide both sides by 3.1415
r^2+4.2r=100
subtract 100 from both sides
r^2+4.2r-100=0
factor
(x-8.11812)(x+12.3181)=0
so (if xy=0 then x or/and y must be 0 so)we set them to 0 so
x-8.11812=0
x=8.11812

second one
x+12.3181=0
x=-12.3181
since radii (or any legnth) cannot be negative, we can cross this solution out so

radius=8.11812
