She uses 11/36 yards of string for each.
In this problem, you're dividing the amount of string by the number of banners, so 11/12 ÷ 3. To do this though, it's easiest to convert the 3 into a fraction. After you do this, you're left with:
11/12 ÷ 3/1
When dividing fractions, you flip the second fraction upside down and change the operation to its opposite, which gives you:
11/12 × 1/3
Then you just multiply across. 11×1=11 and 12×3=36, so you're left with 11/36 yards of string.
Answer:
cost price = 5000 rs.
selling price = 6500 rs.
as selling price > cost price there is a profit
profit = selling price - cost price = 6500 - 5000 = 1500 rs.
profit percentage = profit x 100 / cost price = 1500 x 100 / 5000 = 30 %
By factoring the quadratic equation, 4 porcelain vases can be glazed with 20 pints of glaze. (Correct choice: B)
<h3>How much vases can be glazed with a certain amount of pints of glass?</h3>
Herein we have a quadratic equation that models the quantity of pints as a function of the number of vases, we need to solve the quadratic equation for v to find the required quantity. The complete procedure is shown below:
v² + v = 20 Given
v² + v - 20 = 0 Compatibility with addition / Existence of the additive inverse / Modulative property
(v + 5) · (v - 4) = 0 x² - (r₁ + r₂) · x + r₁ · r₂ = (x - r₁) · (x - r₂)
The result must be a positive number and, thus, the maximum number of vases must be equal to 4. By factoring the quadratic equation, 4 porcelain vases can be glazed with 20 pints of glaze. (Correct choice: B)
