Answer:
Your <u>correct</u> answer is 14t - 40
Step-by-step explanation:
Combine like terms:
10t + 3t + t = 14t
Since there are no other integers, just tag on the -40:
14t - 40

Answer:
15.035 years
Step-by-step explanation:
The exponential function to calculate population growth is
P(t) = Poe^kt
P(t) = Population size after t years = 3.6 million
Po = Initial population size = 2.1 million
k = growth rate = 3.65% = 0.0365
t = time in years = ???
Hence:
3600000 = 2100000 × e ^0.0365t
Divide both sides by 2100000
3600000/2100000 = e^0.0365t
1.7142857143 = e^0.0365t
Find the log of both sides
Log 1.7142857143 = log (e^0.0365t)
Log 1.7142857143 /Log 0.0365 = t
t = 15.035 years
50 / (3/7) =
50 * 7/3 =
350/3 =
116.66....so it would fill 116 glasses
Answer:
The equation would be y=4x+1
This is because b is the y intercept and would cross the graph at +1
Distance ran by Tara = 1600 m
Time taken by Tara to ran 1600 m = 5 min 20 seconds
We have to calculate the speed.
Firstly, we will convert the unit of time in one unit.
Time = 5 min 20 seconds
= 5 min +
min (Because 1 min = 60 sec)
= 
=
=
min
Now we will use Distance speed formula which states,
Distance = speed 
time
1600 m = speed
speed = 
Speed = 300 m/min
So, the speed of Tara was 300 meter/min.
