Mathematics
1 answer:
ch4aika [34]2 years ago
6 0

Answer:

B

Step-by-step explanation:

A rational number can be expressed in the form

\frac{a}{b} ← where a and b are integers

From the set

3 is rational as it can be expressed as \frac{3}{1}

and \sqrt{9} = 3 ← rational

\sqrt{2}, \sqrt{3} and \sqrt{7} ← are irrational numbers

Thus there are 2 rational numbers out of the 5 given, thus

P( rational ) = \frac{2}{5} → B

What is the area??????
Westkost [7]
Your answer would be 91.1 units².
We can split this shape into a trapezium and a semicircle, and then find the area of both and add them.
To find the area of a trapezium, the formula is
(a + b)/2 × h, which means we do 14 (the length of AD) + 8 (the length of BC) = 22, and 22/2 = 11. Then we multiply 11 by the height of the trapezium, which is 6 because 10 - 4 = 6. This gives us the area of the trapezium as 66 units².
To find the area of a semicircle, the formula is πr²/2, and the radius is 4 because the diameter is 8 (16 - 8 = 8). This means we do π4²/2 = 16π\2 = 8π = 25.13.
Then we need to add together 66 and 25.13, which equals 91.13, or 91.1 to the nearest tenth.
I hope this helps!
