Answer:
5:9
Step-by-step explanation:
the ratio of the number of girls to the number of boys who attended the competition is 5:9
3/2x - 3 = y
using y = mx + b, where m is slope and b is the y intercept, we can eliminate the top two answers by finding the y intercept at -3.
You can find the slope of the graph by using any given point and then calculating rise over run. In this case, the rise is 1.5, and the run is 1, which equates to 3/2
b = -3
m = 3/2
Answer:
The inequality best represents the length of the femur that would suggest the woman had a height greater than 160 cm is:
f > 40
Step-by-step explanation:
Woman's height (cm): h = 60 + 2.5 f
Length of the femur (cm): f
Height greater than 160 cm:
h > 160
Replacing h by 60+2.5f in the inequality above:
60+2.5f > 160
Solving for f: Subtracting 60 both sides of the inequality:
60+2.5f-60 > 160-60
Subtracting
2.5f > 100
Dividing both sides of the inequality by 2.5:
2.5f/2.5 > 100/2.5
f > 40
Answer: The inequality best represents the length of the femur that would suggest the woman had a height greater than 160 cm is:
f > 40
