Answer:
See below
Step-by-step explanation:
Part A
<em><u>Formula</u></em>
M = 2/3 * log(E/Eo)
<em><u>Givens</u></em>
M = ??
E = 2 * 10^15 joules
Eo = 10^4.4
<em><u>Solution</u></em>
M = (2/3) * log(2 * 10^15 / 10^4.4)
M = (2/3 ) log (7.96 * 10 ^ 11)
M = (2/3) * 11.901
M = 7.934
Part B
What the question is saying is that E/Eo = 10000
You don't have to figure out exact values.
M = 2/3 * log(10000)
M = 2/3 * 4
M = 8/3 or 2 2/3 or 2.66667
If you have choices, please list them.
Hello there!
The answer to your question is:
-(2.6+2.9+7.1)
This is because that negative sign can be distributed into the parentheses to get the same expression.
-2.6-2.9-7.1=-2.6+(-2.9)+(-7.1)
I hope this helps!

Answer:
33
Step-by-step explanation:
To find the interquartile range , first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 and quartile 3 . The IQR is the difference between Q3 and Q1.
A=k/b, where k is a non zero constant.
When a=0.5, b=3.25, is
0.5=k/3.25
k=3.25×0.5=1.625
meaning that when there is a value for b, dividing 1.625 by it will form the value of a.
therefore, when b=2, 1.625/2=0.8125, which is 13/16.
answer is 13/16
Answer:
They baked 54 brownies
Step-by-step explanation:
We have a total of b brownies
Then we threw away 24
b-24
Then we split them between the 3 siblings
(b-24)/3
Everyone got 10
(b-24)/3 =10
Solve for b
(b-24)/3 =10
Multiply by 3 on each side
(b-24)/3 *3 =10*3
b-24 = 30
Add 24 to each side
b-24+24 = 30+24
b = 54
They baked 54 brownies
