Answer: 45
Step-by-step explanation:
The rectangle is: 7 * 5
The triangle is: (4 * 5)/2
7 * 5 = 35
4 * 5 = 20
20/2 = 10
10 + 35 = 45
Answer:
yes
Step-by-step explanation:
Odd question; there's no real rate exact 50 meters per lap (assuming the last is a typo), i.e we have a 50 meter pool.
d = 50 n
so when n=15
d = 50(15) = 750 meters
Answer:
(7.5)^2 pi
Step-by-step explanation:
Circumference= pi x diameter
area= radius^2 x pi
radius= 1/2 diameter
1. find radius: 15/2= 7.5
2. square radius: (7.5)^2
3. multiply by pi: (7.5)^2 x pi
Total number of cards = 52
Total number of spades = 13
Total number of face cards that are not spades = 3 x 3 = 9
Total number of spades or face cards = 13 + 9 = 22
P(a or b) = 22/52 = 11/26
Answer: 11/26
