A room is 20 feet by 25 feet with a 10-foot ceiling. If Mickey paints the walls and the ceiling, how much surface area will he c

Svetradugi [14.3K]

Answer:

1400ft²

Step-by-step explanation:

Given

Room Dimension: 20 ft by 25 ft by 10 ft

Where Length = 20 ft

Width = 25 ft

Height = 10 ft

Required

Surface area of painted walls and ceiling

We'll assume that the room is rectangular in shape and all 4 sides are covered.

<em>This means that Mickey will paint 4 walls and 1 ceiling.</em>

The dimension of the 2 of the 4 walls is as follows;

20ft by 10ft, 25ft by 10ft,

Because opposite sides of a rectangle are equal, the dimension of the remaining 2 walls is: 20ft by 10ft, 25ft by 10ft

Calculating the area of the 4 walls;

$Area = 20ft * 10ft + 25ft * 10ft + 20ft * 10ft + 25ft * 10ft$

$Area = 200ft^2 + 250ft^2 + 200ft^2 + 250ft^2$

$Area = 900ft^2$

The dimension of the ceiling is as follows:

20ft by 25ft

Calculating the area of the ceiling

$Area = 20ft * 25ft$

$Area = 500ft^2$

So, the area Micky will cover = Area of 4 walls + Area of ceiling

Total Surface Area $= 900ft^2 +500ft^2$

Total Surface Area = $1400ft^2$

Hence, Micky will cover 1400ft²

3 times a number x, subtracted from 18, is less than−90.

Leokris [45]

3x-18 is less than -90
First, you add 18 to both sides of the inequality (getting 3x is less than -72). Then you divide by 3 on both sides giving you your answer x is less than -24

Answer: Addition and subtraction is performed after multiplication, division and remainder

Step-by-step explanation:

The correct order of operations is to calculate whatever is in the parenthesis first.

Then calculate multiplication and division depending on which comes first as you move from left to right.

Then addition and subtraction can be performed also depending on which comes first as you move left to right.
