Answer:
6 ft/min
Step-by-step explanation:
Theres a neat trick to note; whenever you say per think of it as a fancy word for divide, because the label is always gonna be a/b (a per b)
Therefore,
the rate of feet per minute will be the feet divided by the minutes;
18 feet in 3 minutes = <u>18</u>/3 <u>ft</u>/min
Therefore the rate is 6 feet per minute.
<u>IF you need an explanation on what average rate implies:</u>
<em>Note; the word average is not prudent to answer as its extraneous, however if there was more data like "Cami descends 18 ft in 3 min and Nami descends 9 ft in 3 minutes; whats the average rate at which they descend" then you'd have to add the two rates up and divide by two.</em>
Hope this helps :)
Answer:
Range : {11,27,43,59}
Step-by-step explanation:
Given:
f(x) = 4x - 1
Domain : {3,7,11,15}
f(3) = 4(3) -1 = 11
f(7) = 4(7) -1 = 27
f(11) = 4(11) -1 = 43
f(15) = 4(15) -1 = 59
hence Range : {11,27,43,59}
You would do 1/4 and get the answer plus 3/8s answer
The first answer we see is true the other is based on personal experience
