Probabilities! In order to find the answer you first have find out the total amount of marbles that you have. So:
[7 + 9 + 6] = 22
This number will go into the denominator.
The next step is to find how how many marbles are not green. To do that you simply add the red marbles and the blue marbles. So:
[7 + 9] = 16
This number will go in the numerator.
The probability of you choosing a marble that is not green is 16/22. You can also simply this and it would be 8/11.
Answer: 10 inches.
Step-by-step explanation:
v=l*w*h
Let’s plug in your numbers:
4,331.25=22.5*19.25*h
Let’s simplify it.
4,331.25=433.125*h
Then divide both sides by 433.125 (.125=1/8 by the way).
10=h
The height is 10 inches.
Answer:
x = 10 m∠3 = 74
Step-by-step explanation:
(10x + 6) + (7x + 4) = 180 degrees
17x + 10 = 180
17x = 170
x = 10
check answer
(10(10) + 6) + (7(10) + 4) = 180
106 + 74 = 180
180 = 180
true!
angle 5 is vertical angles with 3, so they are congruent
use same equation as 5
7(10) + 4
70 + 4
74 :)
Answer:
The percentage rate of decay per year is of 3.25%.
The function showing the mass of the sample remaining after t is 
Step-by-step explanation:
Equation for decay of substance:
The equation that models the amount of a decaying substance after t years is given by:
In which A(0) is the initial amount and r is the decay rate, as a decimal.
Every 21 years, its mass decreases by half.
This means that 
. We use this to find r, the percentage rate of decay per year.
![\sqrt[21]{(1-r)^{21}} = \sqrt[21]{0.5}](https://tex.z-dn.net/?f=%5Csqrt%5B21%5D%7B%281-r%29%5E%7B21%7D%7D%20%3D%20%5Csqrt%5B21%5D%7B0.5%7D)
The percentage rate of decay per year is of 3.25%.
Given that the initial mass of a sample of Element X is 80 grams.
This means that 
The equation is:
The function showing the mass of the sample remaining after t is
Your answer would be: 4.62e-11
