Answer:

Rectangle A is not a scale drawing.

Rectangle B is a scale drawing.

Step-by-step explanation:

A scale drawing involves ratios.

Rectangle A:

10cm is double the original 5cm giving us a 1 : 2 ratio.

However, 25cm is <em>not</em> double the original 20cm. This means that this rectangle is not to scale of the given rectangle.

Rectangle B:

10cm is double the original 5cm giving us a 1 : 2 ratio once again.

This time however, 40cm is double the original 20cm. This means that this rectangle is a scale drawing of the given rectangle.

~Hope this Helps!~

Write an equivalent expression to 9y -1/2(4y+20)
Leya [2.2K]
An equivalent expression could just be one that is simplified. So we get 9y - 2y - 10 if we distribute the 1/2, which is 7y - 10.

14. Of the 400 students in the 8th grade, four-
In-s [12.5K]

Answer:

8 or 9

Step-by-step explanation:

So, you first need to take 4/5 of 400 (320).  Then, you can count by 75s for a bit

75students; 2chaperones

150; 4

225; 6

300; 8

now, you have 20 students left over...since one chaperone would watch about 37 kids, you can either divide the remaining kids up among the other chaperones, or you can add one more chaperone to watch the 20 kids.  i don't know what the teacher wants, so either 8 or 9 chaperones
