What is the scale factor of the dilation

Marizza181 [45]

Looking at how the image shrinked from the original, you can assume that the scale would be a fraction. Since they remained negative, then the fraction wouldn't contain a negative. Therefore the answer would be C.

nignag [31]

Answer:

39

Step-by-step explanation:

To find the intervals you will need to find the lowest and highest numbers, in this case, it would be 1 and 35. A general rule would be 5-7 intervals, I will use 5.

Here are the intervals with the number of people that were in each:

1-7 (9)

8-14 (14)

15-21 (8)

22-28 (3)

29-35 (5)

14+9+8+3+5=39

Help plz<br>Find the measurement of the angles of a triangle if they are in the ratio 5:4:3

Lerok [7]

Answer:

<u>See below:</u>

Step-by-step explanation:

Let the angles be 5x , 4x , 3x.[Since the angles are in ratio 5:4:3 ] respectively.

We know that sum of all angles of a triangle is 180°.

So,

$5x + 4x + 3x = 180 {}^{ \circ}$

Now Find the value of x of this equation.

$\sf \implies \: 5x + 4x + 3x = 180 {}^{ \circ}$

$\sf \implies12x = 180 {}^{ \circ}$

$\sf \implies \: x = \cfrac{180 { {}^{ \circ} }}{12}$

$\sf \implies \: x = \cfrac{ \cancel{180 {}^{ \circ}} }{ \cancel{12}}$

$\sf \implies \: x = 15 {}^{ \circ}$

Now,

Multiply each ratio given by 15 which is the value of x we got.

That is;

$\therefore \sf\implies \: First \: Angle = 5 \times 15 {}^{ \circ} = \boxed{75 {}^{ \circ}}$

$\sf \sf \implies \: Second\: Angle = 4\times 15 {}^{ \circ} = \boxed{60 {}^ \circ}$

$\sf \implies \: Third\: Angle = 3 \times 15 = \boxed{ {45}^ \circ}$

Hence,the measurements of the angles of the triangle would be 75°[First Angle],60°[Second angle],and 45° [Third Angle].

$\rule{225 pt}{2pt}$

I hope this helps!
