Find the area of the shaded region.

kondor19780726 [428]

The region is made up of

• a right triangle with short leg 10 m and hypotenuse 26 m

• a parallelogram with sides 40 m and 26 m (the 26-m side corresponds to the aforementioned hypotenuse)

• another triangle with two known legs of length 20 m and 26 m

Find the height of the right triangle using the Pythagorean theorem. If the height is h, then

(10 m)² + h² = (26 m)² ⇒ h² = 576 m² ⇒ h = 24 m

This height is common to all three shapes.

Now find the area of each shape.

• right triangle:

1/2 × (10 m) × (24 m) = 120 m²

• parallelogram:

(40 m) × (24 m) = 960 m²

• other triangle:

• 1/2 × (20 m) × (24 m) = 240 m²

Then the total area of the shaded region is 1320 m².

The mean computed from ungrouped data is a more accurate measure than the mean computed from grouped data?

<h3>⚜Cost + Mark-up= Selling price</h3>

Why is this an important equation for businesses that sell products?

This equation is important for businesses that sell products because this formula can help them find the selling price of items.
And we know that selling price can be used to determine profit or loss. Determination of profit and loss is important when running a business.

Next, rearrange the equation to solve for ‘Markup.’ In other words, ‘Markup = …’. What is that equation saying about Markup? How is ‘Markup’ related to the other two quantities?

Mark-up = Selling price - Cost
Since, The sign of constant is changed when moving to the other side, The positive Cost will become negative.
This equation is telling us the mark-up price when the selling price and cost is known.
Mark up is the Cost that is not given, In other words Mark up is the price subtracted after giving discount on something.
