Answer:
about 23 inches
Step-by-step explanation:
Table:
<span>Years (x) 1 2 3 4 5 6
Money (y) (hundreds of dollars) 15 30 45 60 75 90
</span>
y = 15(x)
y = 15(9)
y = 135 hundreds of dollars
<span>y = 15x, in 9 years he will have saved $13,500</span>
This is an easy half-life problem.
Every half-life, a substance loses half its radioactivity. So, after 2 half-lives, a substance will have a quarter of its radioactivity.
2 * 5,700 = 11,400 years
answer is C
I'm pretty sure it's d. y=-3x
Answer:
28% as a fraction can be written in many ways. The most simplest way to convert a percentage to a fraction would just to put it over 100. For example, 50% would be 50/100 therefore 28% would be 28/100.
However, we can simplify that fraction even more by doing (28/4)/(100/4) which would give us 7/25.
