Drag and drop the constant of proportionality into the box to match the table. If the table is not proportional, drag and drop "
olga_2 [115]

Answer: not proportional


Step-by-step explanation:

The constant is called the coefficient of proportionality if one variable is always the product of the other variable and a constant. And the variables are said to be directly proportional.

In the given table , let the variables are proportional then the constant of proportion(k)=\frac{y}{x}

\Rightarrow\ k=\frac{3}{2}=1.5

\Rightarrow\ k=\frac{7}{4}=1.45

⇒ k is not a constant of proportionality.

⇒ the variables x and y are not proportional.

For the polyhedron, use Euler's Formula to find the missing number.
disa [49]

If the number of the edges of the polyhedron is 14 and the vertices are 9. Then the number of the faces of the polyhedron is 7.

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

A polyhedron is a solid made composed of polygons in three dimensions. It has vertices, flat faces, and straight edges.

We know the Euler's formula

F + V - E = 2,

where, F = number of faces, V = number of vertices, and E = number of edges

Edges: 14

Vertices: 9

F + 9 - 14 = 2

            F = 14 + 2 - 9

            F = 16 - 9

            F = 7

Then the number of the faces of the polyhedron is 7.

More about the polyhedron link is given below.

The expression 2y + 2.7 is equal to for y = 4. ​
Darya [45]

Answer:

10.7

Step-by-step explanation:

i am not certain but since y is the 4 you will have 2(4) + 2.7 so you get 8+2.7 since you do 2x4 then you add 8 and 2.7 to get 10.7
