During one calendar year, a state trooper issued a total of 375 citations for warnings and speeding tickets. Of these, there wer
timama [110]

Answer:

169 Speeding Tickets, 206 Warnings.

Step-by-step explanation:

If there were 37 more warnings than tickets, then the first thing you want to do is remove that from the total by subtracting it: 375-37 = 338.

You then halve this to split them into tickets and warnings: 338/2 = 169.

Lastly, you add back the 37 more warnings, giving you 169 speeding tickets and 206 warnings.

If p q r is prime numbers such that pq+r=73, what is the least possible value of p+q+r
Jobisdone [24]
The answer to this question would be: p+q+r = 2 + 17 + 39= 58

In this question, p q r is a prime number. Most of the prime number is an odd number. If p q r all odd number, it wouldn't be possible to get 73 since
odd x odd + odd= odd + odd = even
Since 73 is an odd number, it is clear that one of the p q r needs to be an even number. 

There is only one odd prime number which is 2. If you put 2 in the r the result would be:
pq+2= 73
pq= 71
There will be no solution for pq since 71 is prime number. That mean 2 must be either p or q. Let say that 2 is p, then the equation would be: 2q + r= 73

The least possible value of p+q+r would be achieved by founding the highest q since its coefficient is 2 times r. Maximum q would be 73/2= 36.5 so you can try backward from that. Since q= 31, q=29, q=23 and q=19 wouldn't result in a prime number r, the least result would be q=17
r= 73-2q
r= 73- 2(17)
r= 73-34=39

p+q+r = 2 + 17 + 39= 58

Line CD contains points A (4, 6) and B (−2, 6). What is the slope of the line CD?
vazorg [7]
The slope of the line given the points is calculated through the equation,
                                 m = (y2 - y1) / (x2 - x1)
Substituting the known values,
                                 m = (6 - 6) / (-2 - 4)   = 0
The slope of the given line is equal to 0 which means that it is a horizontal line.
