Answer:
B
Step-by-step explanation:
a proportional relationship must have a straight line when graphed and it must go through the origin (0,0)
Right off the bat we can eliminate answer choice C because the line is not straight
the answer is not a nor d
the line may be straight but it does not go through the origin therefore it is not a proportional relationship
B makes a straight line and the line goes through the origin therefore B is the answer
The answer is 5 you’re welcome
Answer:
The actual mass is either 453 or 447
Step-by-step explanation:
7 percent of 450
= (7/100) * 45
= 3.15
error = 3.15 g
hence actual mass
= 450 + 3.15
= 453.15
or
= 450 - 3.15
= 446.85
The slope is 5/4.
5²+4²=41
√41=6.4
EF=6.4 units.
15/x = 9/4
9x = 60
<em>x = 60/9 = 20/3 = 6.6666</em>
