Mildred’s salary has increased from £24,600 to £25,338. By what percentage has her salary increase?
Illusion [34]

Answer:

<h3>The answer is 3%</h3>

Step-by-step explanation:

To find the percentage increase we use the formula

Percentage  \: change =  \frac{ change}{original \: quantity}  \times 100

To find the change subtract the smaller quantity from the bigger one

From the question

original price = $24,600

Current price = $ 25,338

Change = $25,338 - $ 24,600

Change = $ 738

So the percentage increase is

\frac{738}{24600}  \times 100

=  \frac{3}{100}  \times 100

We have the final answer as

<h3>Percentage increase = 3%</h3>

Hope this helps you

Find the equation of the straight line passing through the point (0,1) which is perpendicular to the line y= -2x + 2
mylen [45]

Answer:

y = 1/2x + 1

In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.

-2 ⇒ 1/2

Next, we need to substitute the information given into the point-slope formula.

The point-slope formula is:

y - y₁ = m(x - x₁)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1

Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.
