How does the DMV point system work?
Elodia [21]

Answer:

A. It keeps track of a driver's offenses so that they can suspend his license if they need to

Step-by-step explanation:

The DMV keeps a record of a person's driving history. This records any accidents or another traffic offenses like red light violations or speed violations etc.

A bus went halfway from a village to a city at a certain speed. Then it stopped in traffic for an hour. In order to catch up the
k0ka [10]
We have to assume that the speed before being stuck was sufficient to get to the destination on time had there been no delay. Call that speed "s" in km/h.

Since 200 km is "halfway", the total distance must be 400 km.

time = distance / speed
total time = (time for first half) + (delay) + (time for second half)

400/s = 200/s + 1 + 200/(s+10) . . . .times are in hours, distances in km
200/s = 1 + 200/(s+10) . . . . . . . . . . subtract 200/s
200(s+10) = s(s+10) +200s . . . . . . .multiply by s(s+10)
0 = s² +10s - 2000 . . . . . . . . . . . . . .subtract the left side
(s+50)(s-40) = 0
Solutions are s = -50, s = 40

The speed of the bus before the traffic holdup was 40 km/h.

15. Evaluate the expression 13 ÷<br> (2.5-1-3).33.
OlgaM077 [116]

Evaluation of the expression using order of operation gives 26/11.

How to evaluate the expression

Given 13 ÷(2.5-1-3).33 =  13 ÷ 33( 2 x 5 - 1 - 3)

To evaluate this expression we need to apply the order of operation rule, BODMAS or PEMDAS.

13 ÷(2.5-1-3).33 =  13 ÷ 33( 2 x 5 - 1 - 3)  Evaluate multiplication

                         = 13 ÷ 33(10 - 1 - 3)        Evaluate what is in the bracket

                        =   13 ÷ 33(6)                  Evaluate division

                        = 13/33 x 6

                        = 78/ 33 = 26/11

Therefore, evaluating the expression gives 26/11.
