We know that this is a geometric sequence. Keep in mind that in a geometric sequence, the next term is found by shamelessly multiplying it by "some number", namely the "common ratio".
therefore, if you divide any "next term" by the "previous term", the quotient will just be that "some number", thus, if 1.5 ÷ 7.5 will give it to us, and is, yeap, you guessed it, is 2.
you can check say 3 ÷ 1.5 or 6 ÷ 3, you'll see it.
so, we know the common ratio is 2, and the first term is 0.75, so
Answer:
petunias, snapdragons, then pansy
Step-by-step explanation:
Ok first, lets find the percentage of 18 out of 40: 18/40= 0.45
The 21 out of 50= 21/50= 0.42
Lastly, 12/30= 0.40
And its very simple to put from least to greatest:
0.40, 0.42, 0.45
Hope this helped ;)
Answer: (0, 1.5)
Step-by-step explanation: Use the midpoint formula
Answer:
m = 2
Step-by-step explanation:
First we must distribute on both sides of the equation. If we distribute the 5 on the left we should end up with,
-20m + 10 = -2(3 + 6m)
Then we can distribute the right side,
-20m + 10 = -6 - 12m
We want to move the m's to one side so let's move the -20m to the right by adding it to both sides.
-20m + 10 + 20m = -6 - 12m + 20m
This gives us,
10 = -6 + 8m
Finally we want to move the -6 over to the left by adding it to both sides.
10 + 6 = 8m
16 = 8m
From here we divide both sides by 8 to get m alone.
m = 2
