slega [8]

<u>Answer:</u>

0.8 meters

<u>Step-by-step explanation:</u>

We know that One Shell Square is the tallest building in New Orleans with a height of about 212 meters and Marlie is creating a scale model of this building, using the scale 250 meters : 1 meter.

So to find the height of the scale model, we can simply use the ratio method.

\frac{212 m}{250m} =\frac{x}{1}

x=\frac{212}{250} = 0.848

Therefore, the height of the scale model to the nearest tenth of a meter will be 0.8 meters.

4n + 8 = 20Which value of n from the solution set 3, 8, 10, 12) will make the equation true ?
Brilliant_brown [7]

The value of n from the solution set is <u>3.</u>

<u>calculation:-</u>

⇒ 4n + 8 = 2

⇒ 4n = 20 - 8

=  4n   = 12

= n = 12/4

⇒ n = <u>3</u>

Therefore, from the given set 3,8,10,12, the value of n will be 3.
