2 paintings
Because 1/4 of 64 is 16.
Day 1: 16 left
Day 2: 1/2 of 16 is 8
Day 3: 1/2 of 8 is 4
Day 4: 1/2 of 4 is 2
So after day four he is left with 2.
Answer:
The ratio of blue to red marbles is 3 to 8.
Hope this helps :) have a good day!
To solve the quadratic equation given by 0=x^2-9x-20, we use the quadratic formula given by:
x=[-b+\- sqrt(b^2-4ac)]/(2a)
where,
a=1,b=-9,c=-20
thus substituting the above values into our formula we get:
x=[9+\-sqrt(9^2-4(-20*1))/(2*1)
x=[9+\-sqrt(161)]/2
x=[9+sqrt161]/2 or x=[9-sqrt161]/2
Answer:
Your answer is 12 and -6
Step-by-step explanation:
12 X -6= -72
12 + -6= 6
