Answer:
8 ≤ x + y
Step-by-step explanation:
First you need to consider what is in the problem.
max number of cups = 8
x = number of peach cups
y = number of blueberry cups
Using this information, create an inequality that represents the situation
8 ≤ total number of cups
total number of cups = x + y
8 ≤ x + y
This is therefore the most representative equation for the situation.
We rewrite the equation:
y = y0 * e ^ (- 0.0002 * t)
In this equation:
I = represents the initial amount of the isotope
We have then:
89% of the isotope left:
0.89 * y0 = y0 * e ^ (- 0.0002 * t)
We clear the time:
e ^ (- 0.0002 * t) = 0.89
Ln (e ^ (- 0.0002 * t)) = Ln (0.89)
-0.0002 * t = Ln (0.89)
t = Ln (0.89) / (- 0.0002)
t = 582.6690813
round to the nearest year:
t = 583 years
Answer:
There will be 89% of the isotope left in about:
t = 583 years
Answer:
3 times as great
Step-by-step explanation:
The most amount of water is 3/4 full
The least amount of water 1/4 full
To get from 1/4 to 3/4, you multiply by 3:
(I made 3 into 3/1 to show how you multiply across easier)
(10/n +6) -3
10/2+6-3
5+6-3
11-3
8
Hope this helped!
