Running time for 1 day = 15
Running time for 1 week = 15*7= 105
So, yes she has completed her goal
Giulia will complete her running goal in seven days.
To determine if Giulia will complete her running goal in seven days, we need to calculate her total running time. Since she runs for an average of 15 minutes each day, her total running time in seven days would be 15 minutes/day * 7 days = 105 minutes. Therefore, Giulia will be able to complete her running goal of 100 minutes in seven days.

Answer:
10.4 hours
Step-by-step explanation:
It is convenient to write the exponential growth function in these terms:
population = (initial value)·((value at later time)/(initial value))^exponent
where ...
exponent = (t - (initial time))/(time difference to later time)
Here, we have ...
So, the exponential function is ...
p(t) = 456·(988/456)^((t-2)/2.2)
__
We can find t for p(t) = 8700 a couple of ways. My favorite is to use a graphing calculator to find t such that ...
p(t) -8700 = 0
This shows t ≈ 10.4 hours.
__
Alternatively, you can solve the equation using algebra.
8700 = 456·(988/456)^((t-2)/2.2)
8700/456 = (988/456)^((t-2)/2.2) . . . . . . . . . . .divide by 456
log(8700/456) = (t -2)/2.2 · log(988/456) . . . . taking logs
2.2·log(8700/456)/log(988/456) = t -2 . . . . . . multiply by the inverse of the coefficient of t
t = 2 + 2.2(log(8700/456)/log(988/456)) ≈ 10.389774
We can expect the population to be 8700 at 10.4 hours.
Hi there!
Step-by-step explanation:
First, you subtract by 8 from both sides of an equation.
x+8-8>14-8
Then, you subtract by the numbers from left to right.
14-8=6
The answer must have a positive sign.
Answer: →→ x>6
Hope this helps!
Have a nice day! :)
