Let m be time in months.   When m=0 we have 2500, when m=3 we have double that.  That makes our equation

A = 2500 \cdot 2 ^{m/3}

For 10 months we get

A = 2500 \cdot 2^{10/3}

if there are 2040 seats in a section of a stadium, 20 seats in the first row, and 4 more seats in each row, how many rows are th
Lorico [155]


2040 = n/2(20+(n-1)4)

4080 = n(20+4n-4)

4080= 20n +4n^2 -4n

1020 = 4n + n^2

n^2 +4n -1020 =0

use common formula (can't write out so just look at answers. sorry)

which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge

By direct division, we will find that the length of each piece of rope is 10.5m

<h3>How to perform the division?</h3>

So e start with a 42 meter long rope and we cut it into 4 equal parts, then we know that each one of these pieces will have a length equal to:

L = (42m/4)

To perform that division, you can see that 42<u> is not a multiple of 4</u>, so we can write:

L = (40m + 2m)/4 = (40m/4) + (2m/4)

The first quotient is just equal to 10m, while the second one is:

(2m/4) = (1m/2) = 0.5m

Then we have:

L =  (40m/4) + (2m/4) = 10m + 0.5m = 10.5m

Each piece of rope has a length of 10.5m
