Answer:
25
Step-by-step explanation:
Since y varies inversely with x, the relation between y and x will be:
Introducing the proportionality constant, we can write:
Using the first set of given values of x and y, we get:
This means, the relation between y and x is:
We have to find y if x = 20. Using this value in above equation, we get:
Thus y would be 25 if x is 20.
Answer:
1) 147
2) 87
Step-by-step explanation:
1) Area of triangle = × base length × height
= × 14 × 10
= 70
Area of a semicircle = ( r is the radius)
Radius = half of diameter = = 7m
Area of semicircle =
= 77 ( Nearest whole number )
Total area = 77 + 70 = 147
2) Divide the shape into 2 rectangles
Area of a rectangle = length × width
Rectangle 1 = 7 × ( 3+3+5 )
= 7 × 11 = 77
Rectangle 2 = 2 × 5
= 10
Total Area = 77 + 10 = 87
