For every £1.00 a company spends on advertising, it spends £0.75 on its website. Express the amount spent on advertising to the
Mandarinka [93]

Answer:

4:3

Step-by-step explanation:

For every £1.00 a company spends on advertising, it spends £0.75 on its website.

From the above question:

The ratio is given as:

Amount spent on advertising : Amount spent on website

= £1.00 : £0.75

Convert ratio sign to division

= 1/0.75

Multiply Numerator and Denominator by 100

= 1 × 100 / 0.75 × 100

= 100/75

= 4/3

= 4 : 3

Therefore, the ratio in its simplest form = 4:3

An angle measure 20 more than the measure of its supplementary angle.What is the measure of each angle?
SOVA2 [1]

Based on the definition of supplementary angles, the measure of both angles are: 80° and 100°.

<h3>What are Supplementary Angles?</h3>

The sum of angles that are supplementary to each other equals 180 degrees.

Let the measure of the supplementary angle be x.

The other angle will be: x + 20.

(x + 20) + x = 180

x + 20 + x = 180

2x + 20 = 180

2x = 180 - 20

2x = 160

x = 160/2

x = 80°

The other angle will be x + 20 = 80 + 20 = 100°.

The measure of the angles are: 80° and 100°.

Here are some answers

<u>Remember if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)</u>

<u>if leg b is unknown, then. b = √(c² - a²)</u>

<u>for hypotenuse c missing, the formula is. c = √(a² + b²)</u>
