Find the constant of proportionality k. Then write an equation for the

Nookie1986 [14]

Answer:

see explanation

Step-by-step explanation:

Given x and y are in proportion then the equation relating them is

y = kx ← k is the constant of proportion

To find k use an ordered pair from the table

Using (2, 10 ), then

10 = 2k ( divide both sides by 2 )

5 = k , thus

y = 5x ← relationship between x and y

The area of the regular hexagon is 169.74 ft2 what is the perimeter, rounded to the nearest tenth

Bess [88]

Answer:

Perimeter of given regular hexagon is 48.5 ft.

Step-by-step explanation:

Let ABCDEF be the regular hexagon as shown in the attached figure.

O be the intersection point of the diagonals EB, FC and AD.

As per the property of regular hexagon, all the 6 triangles formed are equilateral triangles.

In other words,

$\triangle EOD, \triangle DOC, \triangle BOC, \triangle AOB, \triangle AOF , \triangle FOE$ are equilateral $\triangle s$ .

Area of an equilateral $\triangle$ is defined as :

$\dfrac{\sqrt{3}}{4} \times a^{2}$

Where a is the side of $\triangle$ .

Area of hexagon = $6 \times \dfrac{\sqrt{3}}{4}\times a^{2}$

We are given that area of hexagon = 169.74 $ft^{2}$

Let s be the side of hexagon.

$\Rightarrow 6 \times \dfrac{\sqrt{3}}{4}s^{2} = 169.74 ft^{2}\\\Rightarrow s = 8.08 ft$

A regular Hexagon is made up of 6 equal sides, so

Perimeter of a regular hexagon = $6 \times side$

Perimeter = $6 \times 8.08$

$\Rightarrow 48.5 ft$

So, perimeter of given regular hexagon is $48.5 ft$ .

Malala is following this recipe for bread rolls. She uses 400 ml of water. How much of each of the other ingredients does she us

geniusboy [140]

Answer:

320 g flour

8 g salt

12 g yeast

20 ml oil

Step-by-step explanation:

To get from 600 to 400, divide by 1.5

To find the amounts of the other ingredients she will use, divide by 1.5

480/1.5 = 320 g flour

12/1.5 = 8 g salt

18/1.5 = 12 g yeast

30/1.5 = 20 ml oil

I WILL GIVE BRAINLIEST. HURRY PLEASE

notsponge [240]

Answer:

Concept: Linear Algebra

Let us pick -5 and -4 which are one unit apart.
We will find the difference by finding the slope: -3-(-11)/-4-(-5)= 8
Next for 2 units apart we will choose 1 and 3
We do the same thing: 53-37/3-1= 16/2=8
Next we will pick something 2 units apart. Let's pick 0 and 3
Hence we will do the same: 53-29/3-0= 24/3=8
No matter what difference we pick, whether that be one, two or three units, the difference is the same and consistent.
