Perimeter of the carpet = 21.8 m

Area of the carpet = $29.4 $ m^{2}$

Given:

Dimension of the living room:

$l = 4.9 $ m\\w = 6 $ m$

A. Perimeter of the carpet = perimeter of a rectangle

Perimeter = $2(l + w)$

Substitute

$Perimeter = 2(4.9 + 6)\\= 21.8 $ m$

Perimeter of the carpet = 21.8 m (The digits here are significant)

B. Area of the carper = area of a rectangle 

Area = $l \times w$

Substitute

$Area = 4.9 \times 6\\= 29.4 $ m^{2}$

Area of the carpet = $29.4 $ m^{2}$ (the digits here are significant)

Therefore, considering the rules of significant digits:

Perimeter of the carpet = 21.8 m

Area of the carpet = $29.4 $ m^{2}$

What is the answer and work to this problem. 4x+2y=14 2x+y=7

Nimfa-mama [501]

The given system of equation has no solution.

Step-by-step explanation:

step 1 :

The given equations are 4x + 2y = 14 and 2x + y = 7.

step 2 :

Let 4x + 2y = 14 be the first equation.

Let 2x + y = 7 be the second equation.

The solution (x,y) can be determined by solving the two equations, if only the given two equations are different.

step 3 :

In first equation taking 2 out as a common factor on both sides, the equation becomes:

2 (2x + y) = 2 (7)

So, the first equation resembles the second one.

step 4 :

Since both the equations are similar, they cannot be solved to get a solution. Therefore, the system of equation has no solution which is also known as inconsistent.

In scientific notation

mrs_skeptik [129]

$(3.9 \times {10}^{ - 3}) + 0.0026 =$

$(39 \times {10}^{ - 4}) + (26 \times {10}^{ - 4}) =$

$39 \times {10}^{ - 4} + 26 \times {10}^{ - 4} =$

$Factoring \: {10}^{ - 4}$

${10}^{ - 4} \times (39 + 26) =$

$65 \times {10}^{ - 4} = 6.5 \times {10}^{ - 3}$
