<span>To calculate how many pieces that can be cut, we calculate the number of 5 1/2 -inch pieces in 66 inches. To calculate this, we divide 66 by 5 1/2 (i.e. 66 divided by 11/2). 66 divided by 11/2 implies 66 multiplied by 2/11 = 132 / 11 = 12. Therefore, 12 pieces of 5 1/2 - inches pieces can be cut out.</span>

A number of friends decided to go on a picnic and planned to spend rs. 96 on eatables. four of them, however, did not turn up. a
mr Goodwill [35]

The number of those who attended the picnic was 8.

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax^{2} + bx + c = 0 where a, b, c, ∈ R and a ≠ 0.

Such questions are best examples of quadratic equations where  the unknown is simply assumed to be a variable which when substituted according to the conditions yield a quadratic equation which can easily be solved.

Let x represent the whole population.

Total Spending = Rs. 96

Thus, each individual's contribution is equal to 96/x.

Four people did not show up causing

others to contribute Rs. 4 extra.

So the given condition can be written as

96/(x-4) – 96/x = 4

=>96x – 96(x-4) = 4x(x-4)

=> 96x -96x + 384 = 4x2 – 16x

=> 4x2 – 16x – 384 = 0

=> x2 – 4x – 96 = 0

=> (x – 12)(x + 8) = 0

=> x = 12 or x = -8 (neglect)

So x = 12

x-4 = 8  ( because  four of them did not turn up)

∴ The number of those who attended the picnic was 8.

A spinner is split into 4 equal parts labeled 1, 2, 3, and 4.
ivolga24 [154]

Answer:

50%

Step-by-step explanation:

If there are 4 parts to the spinner, 4 is the whole. Since there are 2 even numbers (2&4), the fraction would be \frac{2}{4}, which is simplified to \frac{1}{2}. And because \frac{1}{2} could also turn into \frac{50}{100}, the percentage is 50%.

Hope this helps :)
