In a picture graph, if there is no key specified, then it is already assumed that the viewer knows that each symbol would stand for 1. If each symbol stands for more than one, then a key is required, but if each symbol stands for one, you can assume that the viewer knows.
Answer:
3 hours
Step-by-step explanation:
Recall:
Distance = speed x time
we are given that speed = 18 km/h and distance = 54 km.
hence,
54 = 18 x time (divide both sides by 18 and rearrange)
time = 54/18 = 3 hours
Answer:
10 times greater hun
Step-by-step explanation:
70000 times 10 equals 700000
Answer:
C, y=-2/3x+1
Step-by-step explanation:
using points (0, 1) and (3, -1) obtained from the graph:
slope = -1-1/3-0 = -2/3
use one of the points above lets take (1, 0) and another point (x,y)
slope = y-0/x-1 = -2/3
y=-2/3x+1
My best estimate for this figure is 15
