Ok so first, you need to figure out the change in elevation for each after one min. so we will write it as a ratio
10:-160 20:-300
So for the 10 min one, we will divide both sides by 10
1:-16 So the change in elevation per min. is -16
Now for the 20 one, we will divide by 20.
1: -15 So the change in elevation per min. is 15
So, the 10 min section of the walk the change of elevation was greater. Hope that helps! if you need me to explain something just ask!

Step-by-step explanation:
this is an arithmetic sequence :
a1 = 1
an = an-1 + 2 = a1 + (n-1)×2
the sum of n terms of an arithmetic sequence is
S = n×(a1 + an)/2
n = 5000
an = a1 + 4999×2 = 9999
S = 5000×(1 + 9999)/2 = 5000×5000 = 25,000,000
Answer:
Step-by-step explanation:
get the x alone by subtracting 3 from each side.
3x+3-3<36-3
3x<33
divide by three
3x/3<33/3
x<11
The sales tax is $1.40 and the cost is $21.50. I think!
Answer:
= $ 4344.05
Step-by-step explanation:
Using the formula
A = P (1 +r/n)^nt
Where A is the amount accumulated, P is the principal amount, n is the number of interest periods, t is the time taken in years.
A = $4369.20
r = 0.033
n = 4
t = 21/12
Therefore;
$4369.20 = P ( 1 + 0.033/4)^ (21/12×4)
$4369.20 = P (1.000825)^7
$4369.20 = 1.005789 P
P = $4369.20/1.005789
<u> = $ 4344.05</u>
