Answer:
Step-by-step explanation:
1/R = 1/R1 + 1/R2
R = 15
R1 = 23
The best way to do this question is to convert the resistances to decimals.
1/R = 1/15 = 0.0666666
1/R1 = 1/23 = .04348
0.066666666 = 0.0438 + 1/R2 Subtract 0.0438 from both sides.
0.023188 = 1/R2 Take the reciprocal of both sides.
43.125 = R2
========================
You can use fractions if you prefer. But it will a lot messier.
1/15 - 1/23 = 1/R2
23/345 - 15/345 = 1/R2
8/345 = 1/R2 Take the reciprocal of both sides.
345/8 = R2
R2 = 43.125
Answer:
farming for points sorry
Step-by-step explanation:
One pound is 0.454
So 2 pounds would be 2 multiplied by 0.454 which is 0.907185
Question:
The diagram below shows the graph of a proportional relationship. The plotted point is (6,9) .
What is the unit rate of this graph? Be sure to simplify your answer.
Answer:
The unit rate of this graph is 1.5
Explanation:
The graph shows a proportional relationship and the plotted point is (6,9).
The unit rate of the graph can be determined by the formula,
Thus, from the graph, the coordinates are (0,0) and (6,9)
Substituting the coordinates in the formula, we have,
Subtracting, we get,
Thus, the unit rate of the graph is 1.5
