Answer:
The value of x = 100 ft^3/ day
Step-by-step explanation:
We need to look at what amount of water comes in and what amount of water leaves
What comes in: x ft^3/ day
What leaves : 500x ft^3/ day
We start with 146 000 ft^3
Water in tank = what we start with + what comes in - what leaves
water in tank = 146000 + x*d - 500*d where d is the number of days
After 365 days , the tank has 0 ft^3 of water
0 = 146000 + x*365 - 500*365
Multiply
0 = 146000 + 365x - 182500
Combine like terms
0 = -36500+365x
Add 36500 to each side
36500 = 36500-36500+365x
36500 = 365x
Divide by 365
36500/365 = 365x/365
100=x
The value of x = 100

Exponential rules: add the exponents
Answer:
The value of a = -12.
Step-by-step explanation:
Given that the points are Q( -6, 5) and R ( -2, 3) -
As we know that-
If a line segment AB is with endpoints ( ) and ( ) then the mid points C are-
<em>C = ( , )</em>
Here,
Q( -6, 5) and R ( -2, 3)
then the midpoints C are-
( a/3, 4) = ( , )
We have to find the value of x therefore we need to compare only x coordinate -
<em>a/3 = ( -6 - 2)/2</em>
<em>a/3 = -8/2</em>
<em>a/3 = - 4</em>
<em>a = -12</em>
Hence the value of a = -12.
D is not equivalent because it equals 4/25 y 5 I think
