Answer:
Step-by-step explanation:
Bottom triangle
Area = b * height
b = 4 + 4 = 8 cm
h = 5.75
Area = 1/2 * 5.75 * 8
Area = 23 cm^2
Trapezoid
b1 = 8
b2 = 4
h = 2
Area = (b1 + b2)*h/ 2
Area = (8 + 4)*2 /2
Area = 12
Total area = 23 + 12
Total area = 35
Answer:
Step-by-step explanation:
"Inversely proportional to x" in this situation is represented by a = k/x.
Find k:
Let a = 15 and x = 25, then calculate k:
15 = k/25)
Multiplying both sides by 25 yields k = 15(25), or k = 3/5
3
and so a = -----------
5x
48 = 12*4
12 = 12*1
The greatest common factor of 12 and 48 is 12
10% of 27,650 is 2,765
5% of 27,650 is half of 2,765 = 1,382.50.
answer= 5%.
There are 12 total people who enjoy reading (7+5), of which 5 don't ride a motorcycle. So the relative frequency of people that don't ride motorcycles is
