Answer:
$0.27
Step-by-step explanation:
1/4 The ratio of meters of streamers to cost of streamers is 1 : 0.09
We want to know the ratio of centimeters of streamers to cost of
streamers.
2/4 We need to convert meters to centimeters.
There are 100 centimeters in 1 meter.
So, if 1 meter of streamers costs $0.09, then 100 centimeters of
streamers also cost $0.09.
3/4 The ratio centimeters of streamers to cost for 300 centimeters of
streamers.
Now, we can find an equivalent ratio to find the cost for 300
centimeters of streamers.
4/4 The streamers cost $0.27 per 300 centimeters.
Answer:
∠ ABD = 49°, ∠ CBD = 28°
Step-by-step explanation:
∠ ABD + ∠ CBD = ∠ ABC , substitute values
3x + 22 + 5x - 17 = 77 , that is
8x + 5 = 77 ( subtract 5 from both sides )
8x = 72 ( divide both sides by 8 )
x = 9
Thus
∠ ABD = 3x + 22 = 3(9) + 22 = 27 + 22 = 49°
∠ CBD = 5x - 17 = 5(9) - 17 = 45 - 17 = 28°
Table C represents a function
This is because each x value has only one y value. For the other tables, the x values of 4, 9, and 8 have 2 different y values.
