Answer:
x = 66.5
x + 1 = 67.5
x + 2 = 68.5
x + 3 = 69.5
x + 4 = 70.5
x + 5 = 71.5
x + 6 = 72. 5
x + 7 = 73.5
x + 8 = 74.5
x + 9 = 84.5
Step-by-step explanation:
Given that :
Age of 10 friends are consecutive integers :
Let the ages be :
x, x+1, x+2, x+3, x+4, x+5, x+6, x+7, x+8, x+9
The sum of their ages = 710
Hence,
x + x+1 + x+2 + x+3 + x+4 + x+5 + x+6 + x+7 + x+8 + x+9 = 710
10x + 45 = 710
10x = 710 - 45
10x = 665
x = 665 / 10
x = 66.5
x + 1 = 67.5
x + 2 = 68.5
x + 3 = 69.5
x + 4 = 70.5
x + 5 = 71.5
x + 6 = 72. 5
x + 7 = 73.5
x + 8 = 74.5
x + 9 = 84.5
Answer:
x = -10

Answer:
260,548668 or 260.55 round to the nearest hundreds
Step-by-step explanation:
Area of the trapezoid:
[(major base + minor base)x height]/2
[(22 + 12) x 12]/2 = 204 cm^2
radius = diameter / 2 = 12 / 2 = 6 cm
Area of a semicircle
(radius^2 x pi)/2 = (6^2 x pi)/2 = 56.548668 cm^2
total area = 204 + 56,548668 = 260,548668 cm^2
