Answer:
15 pieces
Step-by-step explanation:
a ratio of 1:3 has 4 total parts, meaning that each part is 5.
20/3 = 15 so that means he has 5 pieces of chocolate and 15 of hard candy.
Answer:
7/9
Step-by-step explanation:
If the chances of an outcome are 2/9, the odds against it can be found by subtracting that from 1.
1 - 2/9
= 7/9
So, the odds against that outcome are 7/9
Answer:
A
Step-by-step explanation:
The gcf of 8 & 18 is 2 because no other number can go into both except 2
the lcm is 72 because thats the lowest number that both of them can be multiplied to get
Answer:
a) 23.5619449 m^2 b) 351.8583772 cm^2 c) 75.39822369 cm^2
Step-by-step explanation:
a):
SA = 2πr^2+2πr
r= 3/2 = 1.5
SA= 2π*1.5^2 + 2π*1.5
SA= 15/2 ∏
SA= 23.5619449 m^2 round it as you want
b): Same steps as "a" but rather than m^2 it is cm^2
the answer will be:
SA= 112π
SA= 351.8583772 cm^2 round it as you want
c): the radius is already given so just place it in place of r
SA= 2π*3^2 + 2π*3
SA= 24π
SA= 75.39822369 cm^2
