Answer:
which part are you stuck on
Step-by-step explanation:
Use the formula for simple interest:
i = p* r* t
Here, $120 = $2000*r* (18/12 years)
$120
Then r = ------------------ = 0.04. That's 4% per year.
$2000(1.5)
Answer:
C
Step-by-step explanation:
Answer:
Sketch the following three graphs:
1) y = (x - 5)²
2) y = -(x - 5)²
3) y = x - 5
First two are parabolas with vertex at (5,0)
Third one is a line which intersects both the parabolas as (5,0)
Answer:
There are multiple possibilities. One is there are 12 boys, and 16 girls. 12+16= 28 which is between 20 and 30. That would be 12:16, which can be simplified to 3:4. There is also 9 boys, and 12 girls. that would be 9:12, which can be simplified to 3:4. Also, 9 + 12 = 21, which is between 20 and 30.
