3/6 = 0.5 for 1 metre

6 metres - 3.00
1 metre - x

$6 \cdot x = 1 \cdot 3 \\
6x=3 \\
x=\frac{3}{6}=\frac{1}{2}=0.5$

1 metre costs 0.5.

In Ms.Khans class,22 out of 25 students hand in their projects on time. What percent of the class hand in their projects on time

Nikitich [7]

88 % students of the class hand in their projects on time

Solution:

Given that, Ms.Khans class, 22 out of 25 students hand in their projects on time

Total number students = 25

Students hand in their projects on time = 22

To find: percent of the class hand in their projects on time

$\text{ percent of class hand in time } = \frac{\text{Students hand in projects on time}}{\text{total students}} \times 100$

Substituting the values, we get

$\text{ percent of class hand in time } = \frac{22}{25} \times 100\\\\\text{ percent of class hand in time } = 0.88 \times 100\\\\\text{ percent of class hand in time } = 88$

Thus 88 % students of the class hand in their projects on time

Use the limit theorem and the properties of limits to find the limit. Picture provided below

sashaice [31]

Answer:

b. 1/2

Step-by-step explanation:

lim (x -3)(x +2)

x-->-∞ ---------------

2x^2 + x +1

= lim (x^2 -3x +2x - 6)

x-->-∞ -----------------------

2x^2 + x +1

= lim (x^2 -x - 6)

x-->-∞ -----------------------

2x^2 + x +1

When we plug in x = -∞, we get indeterminate form.

Now we have to use the L'hospital rule.

d/dx (x^2 - x - 6) = 2x -1

d/dx (2x^2 + x + 1) = 4x + 1

Now apply the limit

lim (2x - 1) / (4x + 1)

x--->-∞

Here we have to degree of the numerator and the denominator of the same. In this case, if x --> -∞, we get the result as the coefficient of the leading term as the result.

According to the rule, we get

= 2/4

Which can simplified as 1/2

The answer is 1/2

Hope this will helpful.

Thank you.
