Answer:
2 because of the way the question is written
2/5 if you get 2 wrong.
Step-by-step explanation:
1/2 * 4/5 of means multiply
numerator: 1*4 = 4
denominator = 2 * 5 = 10
Answer: 4 / 10 but this will reduce. Divide Top and Bottom by 2
4/2 = 2
10/2 = 5
Answer: 2/5
The way you should answer is 2 because the question gives you the fact that it is in 5ths. If you get it wrong then put in 2/5.
Answer:
Initial Amount=1
Decay Factor=0.99987
Decay Rate=0.013%
Step-by-step explanation:
If P = 0.99987ᵃ
I. Initial amount
The initial amount is when a=0
P = 0.99987⁰ = 1
The Pressure at Sea Level=1
II. Decay factor
This is like the decay constant. From the model, P = 0.99987ᵃ, the decay constant/factor is 0.99987.
III. Decay Rate = 1-0.99987 = 0.00013
Expressed in Percentage = 0.013%
Answer:
102
Step-by-step explanation:
3x - 5y = 18 over
-10x + 5y = 10
Add them because the 5y's have the right symbols for us to add
-7x = 28
Divide
x = -4
Now you can plug in -4 for x in one equation, I would use the first equation!
3(-4) - 5y = 18
-12 - 5y = 18
Add 12
-5y = 30
Divide
y = -6
Your solutions are going to be:
x = -4
y = -6
To check your work plug x and y into one equation:
3(-4) - 5(-6) = 18
-12 + 30 = 18
18 = 18
Since 18 does equal 18 you know that your solution's work!
