You have a semicircle attached to a trapezium
Area of semicircle = 1/2 Pi r^2 = 1/2 + pi * 4^2 = 25.13 ( note r = 1/2 * 8 = 4)
Area of the trapezium = h/2 ( sum of 2 parallel sides) = 1/2 * 6 * (13 + 8)
= 63
Total area = 63 + 25.13 = 88.1 to nearest tenth
Answer:
even = 1/2
prime = 1/2
multiple of 5 = 1/6
Step-by-step explanation:
probability is the chances of obtaining a certain result out of many attempts.
when rolling a die, the maximum number of results you can get is 6
Then, calculate how many times each of the occurrences appear(even, prime or multiples of 5)
Even = There are only 3 even numbers from 1 to 6
Prime: There are only 3 primes from 1 to 6
Multiples of 5 = There is only one multiple of 5.
Now you present each of this out of 6:
Even: 3/6 = 1/2
Prime: 3/6 = 1/2
Multiple of 5 = 1/6
This can also be presented as a decimal or percentage:
Even: 50% = 0.5
Prime: 50% = 0.5
Multiple of 5 = 16.67% = 0.16
Hope this helps.
Good Luck
Answer:
part A 17/23
part B 31/40
part C 23/40
part D Yes, sorry you gotta figure that out. Im to lazy to write a sentence
Step-by-step explanation:
The result of division is 21.392
Rounded to the nearest tenth its 21.4 answer
(because the hundredth digit is 9 so you add 1 to the tenth digit.)
