A bill for repairing the breaks on the Johnsons car was $125.25. If 20% of the bill was for parts and the rest for labor, how much were the Johnsons charged for labor?
When the graph rises one square for a run of one square, the slope is 2 km/(0.5 h) = 4 km/h. When the graph rises half that fast, the slope is 2 km/h. When the graph is horizontal, the slope is 0. The slope of the distance vs time curve is the speed.
- S = 4 km/h, when 0 < t < 2 h
- S = 0, when 2 h ≤ t < 2.5 h
- S = 4 km/h, when 2.5 h ≤ t < 3 h
- S = 0, when 3h ≤ t < 4 h
- S = 2 km/h, when 4 h ≤ t < 5 h
Answer:
AB =24
Step-by-step explanation:
So, since all the sides are equal, you can just take two of the sides and set em equal to each other to find x and then, solve for AB
4x+8 =6x
8= 6x-4x
8=2x
8/2 =x
x= 4
Now, find AB, which is 4x+8
4(4) + 8
16+8 = 24

Answer:
126.
Step-by-step explanation:
This is the number of combinations of 4 cards from 9 cards:
= 9C4
= 9! / 4! 5!.
A quick way of calculating this is
9*8*7*6
----------- = 9*2*7 = 126 combinations.
4*3*2*1
