Answer:
Step-by-step explanation:
BED is the same angle as AEC
CEB is 180 - 150 (AEC) =30
Answer:
Option D is correct.
75 miles is the total distance in miles to Kirk's grandmother's house
Step-by-step explanation:
Let x represents the total distance in miles to Kirk's grandmother's house.
As per the statement:
Kirk's family drove 36 miles in 50 minutes, which was 48% of the distance to his grandmother's house
⇒ Distance Kirk's family drove = 36 miles.
then;
36 = 48% of x
Multiply both sides by 100 we get;
3600 = 48x
Divide both sides by 48 we have;
75 miles = x
Therefore, the total distance in miles to Kirk's grandmother's house is 75 miles
Answer:
2nd, 4th and 5th one
Step-by-step explanation:
Hey There!
So remember in order for it to be a proportional relationship it has to be a straight line and it has to go through the origin (0,0)
The 2nd, 4th and 5th ones are non proportional relationships
Why? Well because they don't go through the origin
