Answer:
31.2
Step-by-step explanation:
To work out 60% of 52 you would first need to find 10%. You can do this by dividing 52 by 10, this gives you 5.2.
The final step is to multiply 5.2 by 6, this gives 31.2. This is because in order work out 60% you multiply 10% by 6.
1) Divide 52 by 10.
2) Multiply 5.2 by 6.

b) Use the Quadratic Formula to solve the equation. Write the solution in terms of i.
The two numbers are represented by x and 8 - x. By setting x * (8 - x) = 80, we obtain a quadratic equation which can be solved using the Quadratic formula to find x = 2 and x = -40. However, we ignore the negative solution as we're dealing with positive numbers, resulting in 2 and 6 as the two numbers.
First, let's identify the two numbers. Let's let x represent one of these numbers. Because we're told that the sum of the two numbers is 8, we can express the second number as 8 - x.
Next, let's use this information to write our equation. We're told that the product of our two numbers is 80. In terms of x, we can write this as: x * (8 - x) = 80. Simplify this to obtain the quadratic equation: -x^2 + 8x - 80 = 0.
From this, we can apply the Quadratic Formula, which is x = [-b ± sqrt(b^2 - 4ac)] / (2a). Substituting a = -1, b = 8, and c = -80 into the formula, we find the solutions are x = 2 and x = -40. However, since we're dealing with positive numbers here, we can ignore the negative solution, leaving us with the two numbers as 2 and 6.

Answer:
122.5g
Step-by-step explanation:
You would multiply 140 by 12.5% to get 17.5, and then you subtract 140-17.5 to get your answer of 122.5g.
