Answer:
y = 2.4
Step-by-step explanation:
Given y varies inversely with x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 8 when x = 3
k = yx = 8 × 3 = 24
y = 
← equation of variation
When x = 10, then
y = 
= 2.4
Answer:
-1/9
Step-by-step explanation:
Shaded area = 21.46
Step-by-step explanation:
First find area of square,
Area = length × width
A = 20 × 20
A = 400 cm^2
Secondly, find area of circle
Area of circle = (π)r^2
A = (π)10^2
A = 100 π
Thirdly, find the area outside of the circle
Area of square - Area of circle
400cm^2 - 100π
= 85.84
lastly divide the answer by 4 to find the shaded area
85.84 ÷ 4
= 21.46
