Hey there!
A dolphin swims 40 miles per hour. In feet, this is 211,200 because there’s 5,280 feet in a mile. Divide 211,200 by 60 to get 3,520. The dolphin travels 3520 feet a minute.
I hope this helps!

UW=67
Answer:
$760
Step-by-step explanation:
The number of adult ticket is the same as the number of (age 5-12) tickets.
Let the number of adult ticket be x
Number of (age 5-12) tickets be x
Total ticket sold = 38
x + x = 38
2x = 38
x = 19
Cost of each adult ticket = $23
Total cost for 19 such tickets = 23×19
= $437
Cost of each (age 5-12) ticket = $17
Total cost for 19 such tickets = 19×17
= $323
Total cost of 38 tickets = 437 + 323
= $760
Hence, the total cost of tickets is $760

The second option is the correct answer
A function has the property that each element of the domain maps to only one element. For example, if there's ever the case where a relation includes point (1,2) and (1,3) then that relation is not a function. So for each case write down all the points as described. If one point in the domain ever maps to two different points, then it's not a function
