871 divided by 5 is 174.2
Answer:
B, 9
Step-by-step explanation:
Let g represent the number of glass items. Then the number of plastic items is (9g -30). If 85% of items are plastic, then 100%-85% = 15% of items are glass. The ratio of plastic to glass is ...
85%/15% = (9g -30)/g
17/3 = 9 -30/g . . . . simplify
30/g = 9 -17/3 = 10/3 . . . . . . add 30/g -17/3
g = 30(3/10) = 9 . . . . . . . . . . multiply by 3g/10
There are 9 glass items.
_____
<em>Additional comment</em>
The number of plastic items is 9(9) -30 = 51, and the total number of items is 51+9 = 60. The percentage of plastic items is 51/60 = 85%.
__
There are many other ways the equation(s) could be written, including using a system of two equations. For example ...
- p = 9g -30
- p/(p+g) = 0.85 . . . . . plastic is 85% of the total
Answer:
60 degrees
Step-by-step explanation:
On the diagram, we can see that the two angles have a dash on each of them. This means that they have the same measure.
So, if angle ABD is 60 degrees, then angle DBC would also be 60 degrees.
I hope this helps!
