Equation of the existing water pipe's line
a) slope, m = rise / run = Δy / Δx = 3/2
b) y-intercept, b = 3
equation: y = mx + b = (3/2)x + 3
Equation of the new water pipe's line
slope, m = - 1 / (slope of the perpendicular line) = - 1 / (3/2) = - 2/3
point (0,2)
=> y - 2 = (-2/3) (x - 0) => y = (-2/3)x + 2 <---- equation of the new pipe
28)
two parallel lines have the same slope =>
slope, m = rise / run = Δy / Δx = [4 - 0] / [11 - 8] = 4 / 3
point (4,5) => y - 5 = (4/3) (x - 4)
=> y = (4/3)x - 16/3 + 5 = (4/3)x - 1/3
y = (4/3)x - 1/3 <--- equation of the new bike path
Ratio: 303 million to 7.7 billion. Divide 303 million by 7.7 billion ?...
Answer:
42
Step-by-step explanation:
Write 2% as
2
100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
2
100
of 2100 =
2
100
× 2100
Therefore, the answer is 42
If you are using a calculator, simply enter 2÷100×2100 which will give you 42 as the answer.
