Answer:
f(t) = 160t,
d = f(t)
The function that relates the distance traveled d to the time t is:
f(t) = 160t, where d = f(t)
Step-by-step explanation:
If the train travels 480 kilometers in 3 hours, then it will travel 160 kilometers in one hour:
d = 160t
Now we replace d by f(t) because d = f(t):
f(t) = 160t
for any given value of t, d will be equal to t multiplied 160 times
Answer:18
Step-by-step explanation:
Answer:
The answer is 25 plants because all the frequencies add up to 25. While this graph could represent plants when they’re growing, all bars would be the same length though as all plants would hit a certain height.
B) Interval 150-155 has the highest frequency as 8 plants are 150-155cm.
Step-by-step explanation:
Ok,
The total is 63$:
= 63
It shows us one of the numbers for the equation, 13
+ 13 = 63
Two passes together plus the thirteen equals the total of 63$
the price of the pass is unknown, so we can use a variable to figure it out:
2x + 13 = 63
Now we solve
First subtract 13 from both sides:
2x + 13 - 13 = 63 - 13
Then divide both sides by 2:
2x ÷ 2 = 50 ÷ 2
Now we get our answer:
x = 25
Answer:
yes, $20.
Step-by-step explanation:
If you draw a line through the points it makes a straight line, so it is linear. And you get $20 by dividing $100 per the 5 people.
