Answer:

40 books

Step-by-step explanation:

Divide 20 kg by 500 g, or, alternatively, divide 20 kg by 0.5 kg.

Either way, the result is 20/0.5, or 40.

40 books of the same mass would have the same mass as the bookcase.

Hope this helps :)

2 Points<br> What is the center of the circle given by the equation (x+ 5)^2 + (y-8)^2 = 1?
Y_Kistochka [10]

Answer:

(- 5, 8 )

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x + 5)² + (y - 8)² = 1 ← is in standard form

with centre (h, k ) = (- 5, 8 )

I GIVEEEDDE BRAINLILSTTT
Natasha_Volkova [10]

Answer:

\frac{1}{5}

Step-by-step explanation:

To find the scale factor of a dilation, we first find two corresponding sides. For example, the top edge of the black shape corresponds with the top edge of the purple shape. The top edge of the black shape measures 15 units while the top edge of the purple shape measures 3 units

Now, we divide the length taken from the figure by the length taken from the original shape. In this case, we divide the length of 3 by the length of 15.

3/15=\frac{1}{5}

I hope this helps!
