Step-by-step explanation:
50 gallons(8 pints/gallon) = 400 pints
400 pints(4 drops/pint) = 1600 drops red dye
400 pints(3 drops/pint) = 1200 drops blue dye
Answer:
2.4 days
Step-by-step explanation:
Time working together,t ,is
1/t = 1/a+ 1/b where a and b is the times working alone
1/t = 1/4 + 1/6
Multiply each side by 12t to clear the fractions
12t( 1/t )= 12t(1/4 + 1/6)
12 = 3t+2t
12 = 5t
Divide by 5
12/5 = 5t/5
2 2/5 =t
2.4 days
Answer:
--- one of the dimension
Step-by-step explanation:
Given

Required
The side dimension
Factorize the given expression

Factor out x - 5

Volume is the product of base area and height'
Hence:


Answer:
We will add 64 to both sides.
x=8±√20
Step-by-step explanation:
Here we are given the equation:

Now we take half of the coefficient of x and add it to x.
Coefficient of x is 16, half of 16 is 8.
Also we add square of 8 to both sides.
So new equation becomes:

Completing the square:

NOw let us simplify it to get the value of x.
Taking square root on both sides:

Bringing 8 to the right side:
x=8±√20
