Answer:
Variation equation: y = k/√x
constant of variation: 200
Variation Equation by plugging the value of k: y = 200/√x
Step-by-step explanation:
If y varies inversely with the SQUARE ROOT of x, then;
y = k/√x
If x = 4, y = 100.
100 = k/√4
100 = k/2
200 = k
k = 200
Substitute into the expression
y = k/√x
y = 200/√x

10 the inequality would be :
12 inch box is x
15 inch box is y
12x+15y≤84
The amount eroded at millimetre per hour is 0.002283
In order to determine the answer, take the following steps :
1. determine how many hours are in a year
there are 24 hours in a day
There are 365 days in a year
Number of hours in a year = number of days in a year x number of hours in a day
24 x 365 = 8760 hours
2. convert centimetre to millimetre
1 cm = 10mm
2cm x 10 = 20mm
3. Amount eroded per hour in millimetres = amount eroded per year / total number of hours in a year
20 / 8760 = 0.002283 millimetre / hour
