√1x 9/16 

√25/16 

√5^2 / 4^2 

√(5/4)^2 

=5/4 

= 1 x1/4

Explanation

Let:

• M1 = Number of machines in the first case = 8
• D1 = Number of days taken in the first case = 10
• M2 = Number of machines in the second case = 16
• D2 = Number of days taken in the second case =?

The formula for inverse proportion is: M1 * D1 = M2 * D2

Substitute the values: 8 * 10 = 16 * D2 80 = 16 * D2

To find D2, divide both sides by 16: D2 = 80 / 16 D2 = 5

So, it will take 16 machines 5 days to do the work.

Explanation

To evaluate this expression, follow the order of operations (PEMDAS):

1. Evaluate the expression inside the parentheses:

2 + 3 = 5

So, the expression becomes:

8 * 5 - 4^2

2. Multiply 8 and 5:

8 * 5 = 40

3. Calculate 4 squared:

4^2 = 16

4. Finally, subtract 16 from 40:

40 - 16 = 24

25% of 200 is calculated by

multiplying 200 by 25/100,

which equals 50.

Explanation

To solve the equation 4x - 3 = 9:

Add 3 to both sides:

4x = 12

Divide both sides by 4:

x = 3

Explanation

The perimeter of a rectangle is calculated as 2 × (Length + Width).

2 × (7 + 4) = 2 × 11 = 22.

Explanation

2.39x + 2.79y = 1344.50

where x + y = 550.

Solving the equations, we get:

y = 75

So, 75 gallons of premium gasoline were sold.
