The sum of three consecutive numbers is 72. What is the smallest of these numbers?
WINSTONCH [101]
If n stands for the smallest number, then the second and third number would be (n + 1) and (n + 2)

Write the equation based on what are given
the sum of three numbers = 72
n + (n + 1) + (n + 2) = 72

Then, solve the equation
n + (n + 1) + (n + 2) = 72
3n + 3 = 72
3n = 72 - 3
3n = 69
n = 69/3
n = 23

The smallest number is 23

X+y=12
8x+10y=102

8x+8y=96
8x+10y=102 _
-2y= -6
y=3

x+y=12
x=12- 3
x=9

or
8x+10y=102
8x+30=102
8x=102-30
8x=72
x=9

In the figure below, one side of the right triangle is a diameter of the semicircle.
olga55 [171]

Answer:

Option (A)

Step-by-step explanation:

One side of the given triangle is a diameter of the semicircle given.

Measure of the diameter = 10 units

Total area of the semicircle = \frac{1}{2}\pi (r^{2})

                                              = \frac{1}{2}\pi (5)^2

                                              = 39.27 square units

Area of the right triangle = \frac{1}{2}(\text{Base})(\text{Height})

                                         = \frac{1}{2}(6)(8)

                                         = 24 square units

Area of the shaded region = Area of the semicircle - Area of the right triangle

                                            = 39.27 - 24

                                            = 15.27 square units

                                            ≈ 15 square units

Therefore, option (A) will be the answer.
