Answer:
if im right its number 4!! if its not right sorry i did the math and thats what i got!!
Answer:
We know that:
Energy released by fusion of hydrogen in 1 liter of solution A = 7.6x10^10 J
Energy used daily in a certain family home = 3x10^4 J
(you did not write the units, so i suppose that are the same in both cases)
Then, if x is the number of liters of solution A used, the energy produced will be:
E(x) = x*7.6x10^10 J
And we want this equal to 3x10^4
then:
E(x) = x*7.6x10^10 J = 3x10^4 j
now we solve this for x.
x = (3x10^4 j)/(7.6x10^10 j) = 3.9x10^-7
Then you need to use 3.9x10^-7 L of solution a.
Answer:
![\boxed {x = 623}](https://tex.z-dn.net/?f=%5Cboxed%20%7Bx%20%3D%20623%7D)
Step-by-step explanation:
Solve for the value of
:
![-377 = x - 1,000](https://tex.z-dn.net/?f=-377%20%3D%20x%20-%201%2C000)
-Switch sides:
![-377 = x - 1,000](https://tex.z-dn.net/?f=-377%20%3D%20x%20-%201%2C000)
![x - 1,000 = -377](https://tex.z-dn.net/?f=x%20-%201%2C000%20%3D%20-377)
-Add
on both sides:
![x - 1,000 + 1,000 = -377 + 1,000](https://tex.z-dn.net/?f=x%20-%201%2C000%20%2B%201%2C000%20%3D%20-377%20%2B%201%2C000)
![\boxed {x = 623}](https://tex.z-dn.net/?f=%5Cboxed%20%7Bx%20%3D%20623%7D)
Therefore, the value of
is
.
Answer: 165=11h
Step-by-step explanation:
I believe it would be 165=11h because you have to multiply the number of hours she worked times 11 to get the amount that would equal 165!
I would assume b ^5 .. add 3 plus 2 and put it as the power or exponent whatever it’s called
