Start at 125 create a pattern that subtract 6 from each number

Mathematics

Kay [80]3 years ago

If you want a sequence that subtracts 6 each time, then we'd have to have a nth term.

125, 119, 113 etc will be your pattern

Since we are subtracting 6 each time, the nth term will start with -6n

Then we see what that equation looks like: -6 as the first term, -12 as the second etc.

So we have to add a certain amount so the sequence starts at 125, which is to plus 131 to get to 125.

So now the pattern starts at 125 and decreases by 6 each term.

So U_n = -6n + 131

The population of a city in 2005 was 18,000. By 2010, the city’s population had grown to 45,000. If the population growth follow
olga_2 [115]
First find the rate of growth
45000=18000(1+r)^(2010-2005)
Solve for r
r=((45,000÷18,000)^(1÷5)−1)×100
R=20%
Use it to find the population in 2015
P=45000(1+0.20)^(2015-2010)
P==111,974.4

CAn you help me with ratios? Mrs. Sturkie mixed 3 quarts of blue paint and 2 quarts of red paint to make purple paint to her cla
fredd [130]
So as we already know the ratio is 3 quarts blue paint to 2 quarts red paint, also written as 3:2. if she only has 1 quart blue paint she will need half of a quart of red paint because the ratio has to remain the same amount. if you multiply one side then you must multiply the other. same goes with division. If she only has 1 quart of red paint then that shows she divided the 2 red by 2. There fore you would have to divided the 3 by 2 in order to get 1.5 which would then make the ratio 1.5:1
