Answer:
<h3>The number is 500</h3>Step-by-step explanation:
Let the number be x
The quotient of a number divided by five is written as
the number decreased by 400 is written as
x - 400
Equate the two expressions
We have
Multiply through by 5
That's
x = 5x - 2000
x - 5x = - 2000
- 4x = - 2000
Divide both sides by - 4
x = 500
Hope this helps you
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;
The dimension of the ceiling is as follows:
20ft by 25ft
Calculating the area of the ceiling
So, the area Micky will cover = Area of 4 walls + Area of ceiling
Total Surface Area
Total Surface Area =
Hence, Micky will cover 1400ft²
Answer:
The length of the statue's arm is<u> 26.22 ft.</u>
Step-by-step explanation:
Let the length of the statue's arm be 'x'.
Given:
Height of statue is,
Height of male is,
Length of the male's arm is,
Now, as the size of Sam Houston's statue is proportional to that of an adult male, therefore, their heights and arm lengths will also be in proportion. So,
Now, plug in the given values and solve for 'x'.
Therefore, the length of the statue's arm is 26.22 ft
