Cheryl wants to paint a rectangular section on her bedroom wall with texture paint. She makes this scale drawing of the section on a piece of paper using the scale 1 cm = 1.5 ft.



What is the area, in square feet, of the rectangular section of wall that Cheryl will apply texture paint? Round the answer to the nearest tenth.

1 cm = 1.5 ft is your scale

2.5 cm (on the paper) * 1.5 ft (scale) = 3.75 ft

4.5 cm (on the paper) * 1.5 ft (scale) = 6.75 ft

Since area = length * width

3.75 ft * 6.75 ft = 25.3125 ft^2

The area of the rectangular section in square feet that Cheryl will apply texture paint to would be 25.3125 ft^2

Use the proportion to convert millimeters to centimeters. 10mm/1cm=47mm/x
miskamm [114]
- The centimeter is defined as a unit of lenght. Its symbol is: "cm".

 - 1 centimeter=10 milimeters.

 - The milimeter is defined as a unit of lenght and its symbol is "mm".

 1. If you want to convert 47 milimeters to centimeters by using proportions, you have:

 10 mm/1 cm=47mm/x

 2. Then, you only have to clear the "x":

 (10 mm)x=(47mm)(1 cm)
 x=(47 mm)(1 cm)/10 mm

 3. Therefore, the result is:

 x=4.7 centimeters

Solve for x 11^(x-4)=121^(x)
mina [271]

Step-by-step explanation:

11 {}^{x - 4}  = 121 {}^{x}  \\ 11 {?}^{x - 4}  = 11 {}^{11x}  \\ x - 4 = 11x \\ x  - 11x = 4 \\  \\  - 10x = 4 \\ x =  - 0.4

Step 1: 4 x minus x + 2 + 6 = 6 x + 16
anzhelika [568]

The error from Jorge's arithmetic operation on the given algebraic expression is that he distributed it incorrectly.

<h3>What is an algebraic expression?</h3>

An algebraic expression is a mathematical equation that is made up of variables together with arithmetic operations.

From the given expression, we have:

4x - x + 2 + 6 = 6x + 16

Add similar elements together;

3x + 8 = 6x + 16

Using distributive property, subtract 8 from both sides:

3x + 8 - 8 = 6x + 16 - 8

3x = 6x + 8

Simplify

3x-6x = 8

-3x = 8

Divide both sides by -3

-3/-3x = -8/3

x =  -8/3

So from Jorge's calculation, because he distributed incorrectly, we can conclude that could be his error.
