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:
1m 54cm
Step-by-step explanation:
10 students at 1m 40cm
15 students at 1m 58cm
13 students at 1m 60cm
Keep in mind that ratio between cm to m is 1cm/0.01m.
So let find the average by converting cm to m first for the 38 students.
10 students: 1m + (40cm)(0.01m/1cm) => 1.4 m
15 students: 1m + 58cm(0.01m/1cm) => 1.58 m
13 students: 1m 60cm(0.01m/1cm) => 1.60 m
so the average is weighted:
(10*1.4 +15*1.58 + 13(1.6))/38
Therefore the average model height is 1.54 m or 1m 54cm
