The scale factor of the blueprint of a wall to the actual wall is 0.07. The area of the actual wall is 36ft² what is the area of
ss7ja [257]

Answer:

The area of the wall on the blueprint is 0.1764 ft²

Step-by-step explanation:

The scale is the relationship that exists between the magnitudes of a drawing and the actual dimensions.

The scale factor is the ratio of the dimensions in two similar figures. The term "similar figures" refers to figures that have the same shape but different sizes.

 The ratio between areas is equal to the squared scale factor. This is,  the scale factor for areas is the squared scale factor,

To solve scale problems in this case, then the following proportion must be proposed:

\frac{representation area}{actual area} =scale factor^{2}

Being:

  • representation area=?
  • actual area=36 ft²
  • scale factor=0.07

Replacing:

\frac{representation area}{36 ft^{2} } =0.07^{2}

Solving:

representation area= 0.07²*36 ft²

representation area=0.1764 ft²

<u><em>The area of the wall on the blueprint is 0.1764 ft²</em></u>

Yuri [45]

i think first you must multiply $45.5 × 13.7/100

then you will get 6.2335

later you add 6.2335 to $45.5 and you will get $51.7335

i hope it is correct

Factor by gcf 6x2+3x+21 The 2 is supposed to be small.
nexus9112 [7]

Given:

The expression is:

6x^2+3x+21

To find:

The factor of the given expression by GCF.

Solution:

It is given that,

6x^2+3x+21

The terms of the given expression are 6x^2,3x,21. The greatest common factor of these terms is 3.

6x^2+3x+21=3\times 2x^2+3\times x+3\times 7

So, taking out the GCF, the given expression can be rewritten as:

6x^2+3x+21=3(2x^2+x+7)

Therefore, the factor form of the given expression by GCF is 3(2x^2+x+7).
