A number is a solution when it fits within the range of answers that the function generates.
Answer:
8
Step-by-step explanation:
Lines have angles that are equal to 180. Therefore, because we already have 140 of the 180 necessary, we can subtract 140 from 180 to get 40. 40 divided by 5 is 8.
Hope that this helps!
Answer:
The expression used to find the change in temperature per hour is Algebraic expression
Thus per hour; the temperature falls at the rate of
Step-by-step explanation:
A temperature falls from 0 to
in ![3\dfrac{1}{2} \ hours](https://tex.z-dn.net/?f=3%5Cdfrac%7B1%7D%7B2%7D%20%5C%20hours)
Which expression finds the change in temperature per hour.
From the above given information;
The initial temperature is 0
The final temperature is
The change in temperature is ![\Delta T = T_2 - T_1](https://tex.z-dn.net/?f=%5CDelta%20T%20%3D%20T_2%20%20-%20%20T_1)
![\Delta T = -12\dfrac{1}{4} -0](https://tex.z-dn.net/?f=%5CDelta%20%20T%20%3D%20-12%5Cdfrac%7B1%7D%7B4%7D%20-0)
![\Delta T = -12.25](https://tex.z-dn.net/?f=%5CDelta%20T%20%3D%20-12.25)
Thus;
-12.25 ° = 3.5 hours
To find the change in x° per hour; we have;
x° = 1 hour
The expression used to find the change in temperature per hour is Algebraic expression
From above if we cross multiply ; we have;
(- 12.25° × 1 hour) = (x° × 3.5 hour)
Divide both sides by 3.5 hours; we have:
![\dfrac{-12.25^0*1 }{3.5}=\dfrac{ x^0 *3.5}{3.5}](https://tex.z-dn.net/?f=%5Cdfrac%7B-12.25%5E0%2A1%20%7D%7B3.5%7D%3D%5Cdfrac%7B%20x%5E0%20%2A3.5%7D%7B3.5%7D)
x° = - 3.5
x° = ![- 3\dfrac{1}{2}](https://tex.z-dn.net/?f=-%203%5Cdfrac%7B1%7D%7B2%7D)
Thus per hour; the temperature falls at the rate of

Answer:
110 grams
Step-by-step explanation:
CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).
So first finding the mass of 1 molecule of CO2 which is equals to
= mass of 1 carbon atom + masses of 2 oxygen atom, we get
= 12+(16*2)= 12+32= 44 a.m.u.
Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )
1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams
So our answer is 110 grams.
lowkey hope this helped you, good luck whatever you need it for Imaooo
