Solution:

Area of Parallelogram = Base × Height

Opposite Sides of Parallelogram are equal.

⇒  Area of Parallelogram 1 ,

Since it is a Rectangle , because Adjacent sides have angle between their legs has measure equal to 90°.

Product of slopes

    =\frac{6-2}{2-0} \times \frac{2-0}{0-4}\\\\=2 \times \frac{-1}{2}\\\\= -1

Area of Rectangle=Length × Breadth

        =\sqrt{(2-0)^2+(6-2)^2}\times \sqrt{(0-4)^2 \times (2-0)^2}}\\\\=\sqrt{20}\times \sqrt{20}\\\\=20 Square units

⇒Area of Parallelogram 2,

\text{Base}=\sqrt{(2-0)^2+(-8+2)^2}\\\\=\sqrt{40}\\\\=2\sqrt{5}\\\\Height=\sqrt{[2-(-0.4)]^2+[0-(-1)]^2}=\sqrt{5.76+1}\\\\=\sqrt{6.76}\\\\=2.6

Height =2.6 units

   =\sqrt{40} \times 2.6\\\\=6.23 \times 2.6\\\\=16 \text{Square units}Approx

⇒≡ Difference in Area

=Area of Parallelogram 1 - Area of Parallelogram 2

    =20 -16

  =4 Square units  

Option A:

  Area of Parallelogram 1 is 4 unit greater than area of Parallelogram 2.

If the pattern below was tripled, what would be the ratio of black squares to gray squares
andrezito [222]

If the pattern (see attachment) below was tripled, the ratio of black squares to gray squares would be equal to 1:2.

<h3>What is a proportion?</h3>

A proportion can be defined as an equation which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.

Mathematically, a direct proportion can be represented by the following equation:

y = kx

Where:

  • y and x are the variables.
  • k represents the constant of proportionality.

<h3>What is a ratio?</h3>

A ratio can be defined as a mathematical expression that's used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.

For this exercise, the ratio of black square to gray squares is given by:

B:G = 1:2

Tripling the pattern, we would multiply by three (3) as follows:

B:G = [1:2] × 3

B:G = 3:6

Dividing all through by 3, we have:

B:G = [3:6]/3

B:G = 3/3 : 6/3

B:G = 1:2.

Word problem plz help pt.1​
shusha [124]

equation csn be represented as

money left = 500 - (n-1)×4.65

so we can see in first week money left

= 500 - (1-1)×4.65= 500-0=500

which is true because first week chaya got gift card and does not spend any money.

now lets assume that on week n money left is 327.95

so by equation

500 -(n-1)×4.65 = 327.95

500- 327.95 =( n-1)× 4.65

n -1 = 172.05/4.65=37

n = 37+1 = 38

in 38th week money left would be 327.95
