The correct answer is 2160

2160. This is the answer because you must multiply the 3 and 4 for the area of the model and to get it to the real life size you must multiply it by 180.

How do I Round 53879 to the nearest hundred.

Elenna [48]

So,

53,879 rounded to the nearest hundred:

If the number in the tens place is greater than or equal to 5, then round up. If not, round down.

7 is greater than or equal to 5, so round up.

53,879 --> 53,900

HELP NEEDED, GIVING BRAINLIEST!

The correct answer is:

B. This is a dilation about (0, 0) with a scale factor of 4; A'(8, 4), B' (16, 4), C' (16, -12).

Step-by-step explanation:

Given

Dilation: D : (x,y) => (4x,4y)

And Vertices

A ( 2, 1 ), B ( 4, 1 ), C ( 4, -3 )

Applying dilation on all vertices

$A ( 2, 1 ) => A'(4*2, 4*1) => A'(8,4)\\B ( 4, 1 ) = > B' (4*4 ,4*1) = > B'(16,4)\\C(4,-3) => C' (4*4 , 4*-3) => C'(16, -12)$

To find the scale factor,

As we are multiplying each vertex coordinate by 4, the dilation factor is 4.

Moreover,

$\frac{A'}{A} = \frac{(8,4)}{(2,1)} = (4,4)$

Hence the scale factor is 4.

So,

The correct answer is:

B. This is a dilation about (0, 0) with a scale factor of 4; A'(8, 4), B' (16, 4), C' (16, -12).
