Answer:
90 beats per minute
Step-by-step explanation:
By looking at the graph, we see that exactly at second 6, the 9th beat occurs. We can take that to beats/min by multiplying that relation by 10 (since there are ten 6sec in one minute).
9beats every 6sec * 10 = 90beats/min
Answer:
Step-by-step explanation:
Consecutive angles of a parallelogram are are supplementay.
Slope = -1 -4 / 4 --1
slope = -5 / 5
slope = -1
Answer:
increase = 59-50
increase = $9.00
Percent = (increase/whole value) x 100
Percent = (9/50) x 100
Percent = 18%

Answer: y = -(9/5)x - 1
Step-by-step explanation:
Rewrite the equation in standard form: y = (5/9)x+(8/9). [y=mx+b]
A line perpendicular to this would have a slope that is the negative inverse of the original slope (5/9), which would make it -(9/5). The y-intercept would also change, but we don't know the value, yet. For now, we'll use "b" for the y-intercept. This results in a perpendicular line:
y = -(9/5)x + b
We can calculate b, the y-intercept, by using the point (-5,8) and solving for b.
8 = -(9/5)*(-5) + b
8 = (9) + b
b = -1
The line perpendicular to 5x−9y=−8 that passes through the point (−5,8) is
y = -(9/5)x - 1
