The equation of proportion is y equals 2 over 9 x and , y = ( 2/9 )x

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

where y varies directly with x, and y is 16 when x is 72

So , when x = 72 , y = 16

y = kx

16 = k ( 72 )

Divide by 72 on both sides , we get

k = 16 / 72

k = 2/9

Therefore , the value of A is y = ( 2/9 )x

Hence , the equation is y = ( 2/9 )x

Answer:

3)

3.73 mph [miles per hour]

6 km/h [kilometers per hour]

1.67 m/s [meters per second]

4) Yes, because 1.67 m/s is faster than 1.5 m/s

Answer: 2.5

Step-by-step explanation:

I believe 2.5 because If we take y/x we have 4,10 so I divide.

Answer:If the triangles are similar, the ratio of corresponding sides will be equal.

AC / DF = BC / EF

Substitute their values,

12 / 10 = 18 / EF

EF = 18/12 * 10

EF = 3/2 * 10

EF = 30/2

EF = 15 cm

In short, Your Answer would be 15 cm

Answer:

27 cubic meters

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Area of cube = 54 square meters

Let, Side = a

Then, Area of cube = 6[tex]a^{2}[/tex]

54 = 6 [tex]a^{2}[/tex]

[tex]a^{2}[/tex] = 9

a = 3

So, we can calculate the volume of cube by using following formula

Volume of cube = [tex]a^{3}[/tex]

By putting the value in the formula, we get

Volume of the cube = [tex]3^{3}[/tex]

= 27 cubic meters

Step-by-step explanation:

To find the area of a parallelogram, one uses the following formula,

[tex]A=(base)(hieght)[/tex]

Substitute in the given values, and find the area of the parallelogram.

1.

Base = 16

Hieght = 11

 [tex]Area=(base)(height)\\= (11)(16)\\=176[/tex]

2.

Base = 1.5

Hieght = 13

[tex]Area=(base)(hieght)\\=(1.5)(13)\\=19.5[/tex]

Answer:

Q1: 18 degrees

Q2: 60 sides

Step-by-step explanation:

The sum of the exterior angles is always 360 degrees. With this, do 360/20 to get the amount of sides that are within the shape.

360/20  --> 18 degrees.

Now with the interior angles, it can be found with the equation ((n-2) * 180 degrees) / n = Angle Given. With this, plug 174 degres into your equation.

(n-2) * 180 degrees) / n = Angle Given

(n-2) * 180 degrees) / n = 174

180n -360 / n = 174

180n -360 / 174n

360 = 6n

n = 60

It would be 60 sides.
