Answer:
x = ⅔ hr
V = 4 km³
Step-by-step explanation:
The volume of the first cloud is given as:
V1 = 4^(3x - 1)
The volume of the second cloud is given as:
V2 = 8^x
When the two clouds have the same volume, V1 = V2:
=> 4^(3x - 1) = 8^x
We can rewrite this as:
2^[2(3x - 1)] = 2^[3(x)]
=> 2^(6x - 2) = 2^(3x)
According to the law of indices, we can equate the powers because their bases are equal (2 is the base).
=> 6x - 2 = 3x
6x - 3x = 2
3x = 2
x = ⅔ hr
Hence, after 2/3 hr, their volumes will be equal.
To find the volume after 2/3 hr, we can use the equation of either cloud but let us use the equation for the second cloud for simplicity sake:
V2 = 8^(⅔)
V2 = 4 km³ or 4 cubic kilometers
10x6=60 thats it it really is
A number reduced by a number larger would have a negative sum.
Example:
5 - 15 = -10
An easy way to solve equations like this is to subtract the smaller number from the larger number then add a negative sign to the sum.
Example:
5 - 15 would become 15 - 5
15 - 5 = 10
Just add a negative sign and that is the answer.
5 - 15 = -10
Now, to solve your equation, we would first reverse the order.
2 - 233
233 - 2 = 231
Lastly, add the negative sign.
231 would change to -231
Your answer would be -231.
I hope this helps!
