Answer:
width = 5cm
length = 10cm
Step-by-step explanation:
1. the ratio is 1:5 so 50 metres in real life is 10 centimetres on paper so length = 10 cm
2. 25 metres in real life is 5 centimetres on paper so width = 5 cm
Answer:
Step-by-step explanation:
m∠1+∠2=180
2x+40+2y+40=180
2x+2y=180-80
2x+2y=100
x+y=50
x=50-y
m∠1=m∠3
2x+40=x+2y
2x-x=2y-40
x=2y-40
2y-40=50-y
2y+y=50+40
3y=90
y=30
x=50-y=50-30=20
m∠1=2x+40=2×20+40=80°
m∠2=2y+40=2×30+40=60+40=100°
m∠3=x+2y=20+2×30=80°
1.) Which variable did you plot on the x-axis, and which variable did you plot on the y-axis?
x-axis represents people's arms span, y-axis represents their corresponding height
2.) Explain why you assigned the variables in that way.
because you can find the height of people(y) by plugging arm span in x. And i can find people's arm span(x) by plugging height as y
