Answer:
Jamal added 9 purple sox
Step-by-step explanation:
Here, we want to increase the probability
Initially the probability is;
18/(6 + 18 + 12) = 18/36 = 1/2 or 0.5 or 50%
So now, the probability is 60% which is 60/100 or 0.6
If we added x socks, then we number of purple socks become (18 + x)
The total number of x will be (36 + x)
so the probability now will be;
18+x/36 + x = 0.6
18 + x = 0.6(x + 36)
18 + x = 0.6x + 21.6
x-0.6x = 21.6-18
0.4x = 3.6
x = 3.6/0.4
x = 9
Answer:
A1) 125
A2) 47.5%
B) 30
Step-by-step explanation:
Remember 'of' in this sentence means times(*). % shows a certain number/100.
a1) 48% 'of' what number is 60?
(let unknown number be x)
48/100 *x=60
Solve the equation, and the answer is x=125
a2) what percentage 'of' 120 is 57?
(let the unknown percentage be x)
(x/100)*120=57
x=47.5%
b) 24 students= 80% of the total number of students
1%=24/80
100% of the total number of students=30
So, there are total of 30 students
The temperature started at 15 degrees.
It dropped 25 degrees.
Subtract 25 from 15:
15 - 25 = -10
The temperature was -10 degrees.
