Answer:
R = V/I
Step-by-step explanation:
I = V/R
Multiply both sides by r
IR = V
Divide both sides by I
R = V/I
Ex:
2 = 6/3
3 = 6/2

Define price and weight
--------------------------------------------------------------------------------
Let the price of the diamond be y and the weight be x.
--------------------------------------------------------------------------------
General equation for y varies directly as square root of x
--------------------------------------------------------------------------------
y = kx², where k is a constant
--------------------------------------------------------------------------------
Find the constant k
--------------------------------------------------------------------------------
when x = 12, y = 7200
7200 = k(12)²
7200 = 144k
k = 7200 ÷ 144
k = 50
--------------------------------------------------------------------------------
Substitute k into the equation
--------------------------------------------------------------------------------
y = 50x²
--------------------------------------------------------------------------------
Calculate the weight of the two broken diamonds
--------------------------------------------------------------------------------
The diamond is broken into 3:1
3 + 1 = 4
4 shares = 12
1 share = 12 ÷ 4
1 share = 3 decigrams
3 shares = 3 x 3
3 shares = 9 decigrams
Ratio 1 : 3 = 3 decigrams : 9 decigrams
--------------------------------------------------------------------------------
Find price of the of the 3 decigrams
--------------------------------------------------------------------------------
y = 50(3)²
y = $450
--------------------------------------------------------------------------------
Find the price of the 9 decigrams
--------------------------------------------------------------------------------
y = 50(9)²
y = $4050
--------------------------------------------------------------------------------
Total price of the 3 decigrams and the 9 decigrams
--------------------------------------------------------------------------------
$450 + $4050 = $4500
--------------------------------------------------------------------------------
Lost incurred
--------------------------------------------------------------------------------
$7200 - $4500 = $2700
--------------------------------------------------------------------------------
Answer: The lost incurred is $2700
--------------------------------------------------------------------------------
Answer: 4^-2
Step-by-step explanation:
the Bases stays the same the powers changes to negative -2 because you are stubtracting 6-8 which gives you negative -2.
Since you have 4 people total splitting the money, you can find the total amount made in the two months by:
Since you only want the second month, subtract the total profit by the first month profit:
So the answer is $360
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression. Hope this helps! :)
