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

A pharmacist is filling small empty bottles with cough syrup from a larger bottle. He can solve the inequality to find the numbe
andrey2020 [161]

Let us assume capacity of large bottle = 1000 ml.

And capacity of each small bottle = 25 ml.

Reaming milliliters in large bottle = 250 milliliters.

Number of bottles = x bottles.

Total capacity of large bottle - capacity of a small bottle × number of bottles > Reamining milliliters in large bottle.

Therefore, we can setup an inequality.

1000 - 25 × x > 250.

1000 -25x >250.

Please help me with this math question.
alex41 [277]

Answer:

275 m^3

Step-by-step explanation:

The volume of a triangular pyramid is V=(1/3)Ah, where A is the area of the triangular base and h is the height.

First, let's find A, the area of the base. The area of a triangle is bh/2, where b is the base and h is the height.

In this question, 5 is the base and 15 is the height, so A=5*15/2=75/2.

Now we know A is 75/2, so let's go back to the formula for the volume of a pyramid. We are given h is 22, so

V=(1/3)(75/2)*22=275
